*SVN*
* Fixed that HasManyAssociation#count was using :finder_sql rather than :counter_sql if it was available #445 [Scott Barron]
* Added better defaults for composed_of, so statements like composed_of :time_zone, :mapping => %w( time_zone time_zone ) can be written without the mapping part (it's now assumed)
* Added MacroReflection#macro which will return a symbol describing the macro used (like :composed_of or :has_many) #718, #248 [james@slashetc.com]
*1.7.0* (24th February, 2005)
* Changed the auto-timestamping feature to use ActiveRecord::Base.default_timezone instead of entertaining the parallel ActiveRecord::Base.timestamps_gmt method. The latter is now deprecated and will throw a warning on use (but still work) #710 [Jamis Buck]
* Added a OCI8-based Oracle adapter that has been verified to work with Oracle 8 and 9 #629 [Graham Jenkins]. Usage notes:
1. Key generation uses a sequence "rails_sequence" for all tables. (I couldn't find a simple
and safe way of passing table-specific sequence information to the adapter.)
2. Oracle uses DATE or TIMESTAMP datatypes for both dates and times. Consequently I have had to
resort to some hacks to get data converted to Date or Time in Ruby.
If the column_name ends in _at (like created_at, updated_at) it's created as a Ruby Time. Else if the
hours/minutes/seconds are 0, I make it a Ruby Date. Else it's a Ruby Time.
This is nasty - but if you use Duck Typing you'll probably not care very much.
In 9i it's tempting to map DATE to Date and TIMESTAMP to Time but I don't think that is
valid - too many databases use DATE for both.
Timezones and sub-second precision on timestamps are not supported.
3. Default values that are functions (such as "SYSDATE") are not supported. This is a
restriction of the way active record supports default values.
4. Referential integrity constraints are not fully supported. Under at least
some circumstances, active record appears to delete parent and child records out of
sequence and out of transaction scope. (Or this may just be a problem of test setup.)
The OCI8 driver can be retrieved from http://rubyforge.org/projects/ruby-oci8/
* Added option :schema_order to the PostgreSQL adapter to support the use of multiple schemas per database #697 [YuriSchimke]
* Optimized the SQL used to generate has_and_belongs_to_many queries by listing the join table first #693 [yerejm]
* Fixed that when using validation macros with a custom message, if you happened to use single quotes in the message string you would get a parsing error #657 [tonka]
* Fixed that Active Record would throw Broken Pipe errors with FCGI when the MySQL connection timed out instead of reconnecting #428 [Nicholas Seckar]
* Added options to specify an SSL connection for MySQL. Define the following attributes in the connection config (config/database.yml in Rails) to use it: sslkey, sslcert, sslca, sslcapath, sslcipher. To use SSL with no client certs, just set :sslca = '/dev/null'. http://dev.mysql.com/doc/mysql/en/secure-connections.html #604 [daniel@nightrunner.com]
* Added automatic dropping/creating of test tables for running the unit tests on all databases #587 [adelle@bullet.net.au]
* Fixed that find_by_* would fail when column names had numbers #670 [demetrius]
* Fixed the SQL Server adapter on a bunch of issues #667 [DeLynn]
1. Created a new columns method that is much cleaner.
2. Corrected a problem with the select and select_all methods
that didn't account for the LIMIT clause being passed into raw SQL statements.
3. Implemented the string_to_time method in order to create proper instances of the time class.
4. Added logic to the simplified_type method that allows the database to specify the scale of float data.
5. Adjusted the quote_column_name to account for the fact that MS SQL is bothered by a forward slash in the data string.
* Fixed that the dynamic finder like find_all_by_something_boolean(false) didn't work #649 [lmarlow@yahoo.com]
* Added validates_each that validates each specified attribute against a block #610 [bitsweat]. Example:
class Person < ActiveRecord::Base
validates_each :first_name, :last_name do |record, attr|
record.errors.add attr, 'starts with z.' if attr[0] == ?z
end
end
* Added :allow_nil as an explicit option for validates_length_of, so unless that's set to true having the attribute as nil will also return an error if a range is specified as :within #610 [bitsweat]
* Added that validates_* now accept blocks to perform validations #618 [Tim Bates]. Example:
class Person < ActiveRecord::Base
validate { |person| person.errors.add("title", "will never be valid") if SHOULD_NEVER_BE_VALID }
end
* Addded validation for validate all the associated objects before declaring failure with validates_associated #618 [Tim Bates]
* Added keyword-style approach to defining the custom relational bindings #545 [Jamis Buck]. Example:
class Project < ActiveRecord::Base
primary_key "sysid"
table_name "XYZ_PROJECT"
inheritance_column { original_inheritance_column + "_id" }
end
* Fixed Base#clone for use with PostgreSQL #565 [hanson@surgery.wisc.edu]
*1.6.0* (January 25th, 2005)
* Added that has_many association build and create methods can take arrays of record data like Base#create and Base#build to build/create multiple records at once.
* Added that Base#delete and Base#destroy both can take an array of ids to delete/destroy #336
* Added the option of supplying an array of attributes to Base#create, so that multiple records can be created at once.
* Added the option of supplying an array of ids and attributes to Base#update, so that multiple records can be updated at once (inspired by #526/Duane Johnson). Example
people = { 1 => { "first_name" => "David" }, 2 => { "first_name" => "Jeremy"} }
Person.update(people.keys, people.values)
* Added ActiveRecord::Base.timestamps_gmt that can be set to true to make the automated timestamping use GMT instead of local time #520 [Scott Baron]
* Added that update_all calls sanitize_sql on its updates argument, so stuff like MyRecord.update_all(['time = ?', Time.now]) works #519 [notahat]
* Fixed that the dynamic finders didn't treat nil as a "IS NULL" but rather "= NULL" case #515 [Demetrius]
* Added bind-named arrays for interpolating a group of ids or strings in conditions #528 [bitsweat]
* Added that has_and_belongs_to_many associations with additional attributes also can be created between unsaved objects and only committed to the database when Base#save is called on the associator #524 [Eric Anderson]
* Fixed that records fetched with piggy-back attributes or through rich has_and_belongs_to_many associations couldn't be saved due to the extra attributes not part of the table #522 [Eric Anderson]
* Added mass-assignment protection for the inheritance column -- regardless of a custom column is used or not
* Fixed that association proxies would fail === tests like PremiumSubscription === @account.subscription
* Fixed that column aliases didn't work as expected with the new MySql411 driver #507 [Demetrius]
* Fixed that find_all would produce invalid sql when called sequentialy #490 [Scott Baron]
*1.5.1* (January 18th, 2005)
* Fixed that the belongs_to and has_one proxy would fail a test like 'if project.manager' -- this unfortunately also means that you can't call methods like project.manager.build unless there already is a manager on the project #492 [Tim Bates]
* Fixed that the Ruby/MySQL adapter wouldn't connect if the password was empty #503 [Pelle]
*1.5.0* (January 17th, 2005)
* Fixed that unit tests for MySQL are now run as the "rails" user instead of root #455 [Eric Hodel]
* Added validates_associated that enables validation of objects in an unsaved association #398 [Tim Bates]. Example:
class Book < ActiveRecord::Base
has_many :pages
belongs_to :library
validates_associated :pages, :library
end
* Added support for associating unsaved objects #402 [Tim Bates]. Rules that govern this addition:
== Unsaved objects and associations
You can manipulate objects and associations before they are saved to the database, but there is some special behaviour you should be
aware of, mostly involving the saving of associated objects.
=== One-to-one associations
* Assigning an object to a has_one association automatically saves that object, and the object being replaced (if there is one), in
order to update their primary keys - except if the parent object is unsaved (new_record? == true).
* If either of these saves fail (due to one of the objects being invalid) the assignment statement returns false and the assignment
is cancelled.
* If you wish to assign an object to a has_one association without saving it, use the #association.build method (documented below).
* Assigning an object to a belongs_to association does not save the object, since the foreign key field belongs on the parent. It does
not save the parent either.
=== Collections
* Adding an object to a collection (has_many or has_and_belongs_to_many) automatically saves that object, except if the parent object
(the owner of the collection) is not yet stored in the database.
* If saving any of the objects being added to a collection (via #push or similar) fails, then #push returns false.
* You can add an object to a collection without automatically saving it by using the #collection.build method (documented below).
* All unsaved (new_record? == true) members of the collection are automatically saved when the parent is saved.
* Added replace to associations, so you can do project.manager.replace(new_manager) or project.milestones.replace(new_milestones) #402 [Tim Bates]
* Added build and create methods to has_one and belongs_to associations, so you can now do project.manager.build(attributes) #402 [Tim Bates]
* Added that if a before_* callback returns false, all the later callbacks and the associated action are cancelled. If an after_* callback returns false, all the later callbacks are cancelled. Callbacks are generally run in the order they are defined, with the exception of callbacks defined as methods on the model, which are called last. #402 [Tim Bates]
* Fixed that Base#== wouldn't work for multiple references to the same unsaved object #402 [Tim Bates]
* Fixed binary support for PostgreSQL #444 [alex@byzantine.no]
* Added a differenciation between AssociationCollection#size and -length. Now AssociationCollection#size returns the size of the
collection by executing a SELECT COUNT(*) query if the collection hasn't been loaded and calling collection.size if it has. If
it's more likely than not that the collection does have a size larger than zero and you need to fetch that collection afterwards,
it'll take one less SELECT query if you use length.
* Added Base#attributes that returns a hash of all the attributes with their names as keys and clones of their objects as values #433 [atyp.de]
* Fixed that foreign keys named the same as the association would cause stack overflow #437 [Eric Anderson]
* Fixed default scope of acts_as_list from "1" to "1 = 1", so it'll work in PostgreSQL (among other places) #427 [Alexey]
* Added Base#reload that reloads the attributes of an object from the database #422 [Andreas Schwarz]
* Added SQLite3 compatibility through the sqlite3-ruby adapter by Jamis Buck #381 [bitsweat]
* Added support for the new protocol spoken by MySQL 4.1.1+ servers for the Ruby/MySQL adapter that ships with Rails #440 [Matt Mower]
* Added that Observers can use the observes class method instead of overwriting self.observed_class().
Before:
class ListSweeper < ActiveRecord::Base
def self.observed_class() [ List, Item ]
end
After:
class ListSweeper < ActiveRecord::Base
observes List, Item
end
* Fixed that conditions in has_many and has_and_belongs_to_many should be interpolated just like the finder_sql is
* Fixed Base#update_attribute to be indifferent to whether a string or symbol is used to describe the name
* Added Base#toggle(attribute) and Base#toggle!(attribute) that makes it easier to flip a switch or flag.
Before: topic.update_attribute(:approved, !approved?)
After : topic.toggle!(:approved)
* Added Base#increment!(attribute) and Base#decrement!(attribute) that also saves the records. Example:
page.views # => 1
page.increment!(:views) # executes an UPDATE statement
page.views # => 2
page.increment(:views).increment!(:views)
page.views # => 4
* Added Base#increment(attribute) and Base#decrement(attribute) that encapsulates the += 1 and -= 1 patterns.
*1.4.0* (January 4th, 2005)
* Added automated optimistic locking if the field <tt>lock_version</tt> is present. Each update to the
record increments the lock_version column and the locking facilities ensure that records instantiated twice
will let the last one saved raise a StaleObjectError if the first was also updated. Example:
p1 = Person.find(1)
p2 = Person.find(1)
p1.first_name = "Michael"
p1.save
p2.first_name = "should fail"
p2.save # Raises a ActiveRecord::StaleObjectError
You're then responsible for dealing with the conflict by rescuing the exception and either rolling back, merging,
or otherwise apply the business logic needed to resolve the conflict.
#384 [Michael Koziarski]
* Added dynamic attribute-based finders as a cleaner way of getting objects by simple queries without turning to SQL.
They work by appending the name of an attribute to <tt>find_by_</tt>, so you get finders like <tt>Person.find_by_user_name,
Payment.find_by_transaction_id</tt>. So instead of writing <tt>Person.find_first(["user_name = ?", user_name])</tt>, you just do
<tt>Person.find_by_user_name(user_name)</tt>.
It's also possible to use multiple attributes in the same find by separating them with "_and_", so you get finders like
<tt>Person.find_by_user_name_and_password</tt> or even <tt>Payment.find_by_purchaser_and_state_and_country</tt>. So instead of writing
<tt>Person.find_first(["user_name = ? AND password = ?", user_name, password])</tt>, you just do
<tt>Person.find_by_user_name_and_password(user_name, password)</tt>.
While primarily a construct for easier find_firsts, it can also be used as a construct for find_all by using calls like
<tt>Payment.find_all_by_amount(50)</tt> that is turned into <tt>Payment.find_all(["amount = ?", 50])</tt>. This is something not as equally useful,
though, as it's not possible to specify the order in which the objects are returned.
* Added block-style for callbacks #332 [bitsweat].
Before:
before_destroy(Proc.new{ |record| Person.destroy_all "firm_id = #{record.id}" })
After:
before_destroy { |record| Person.destroy_all "firm_id = #{record.id}" }
* Added :counter_cache option to acts_as_tree that works just like the one you can define on belongs_to #371 [Josh]
* Added Base.default_timezone accessor that determines whether to use Time.local (using :local) or Time.utc (using :utc) when pulling dates
and times from the database. This is set to :local by default.
* Added the possibility for adapters to overwrite add_limit! to implement a different limiting scheme than "LIMIT X" used by MySQL, PostgreSQL, and SQLite.
* Added the possibility of having objects with acts_as_list created before their scope is available or...
* Added a db2 adapter that only depends on the Ruby/DB2 bindings (http://raa.ruby-lang.org/project/ruby-db2/) #386 [Maik Schmidt]
* Added the final touches to the Microsoft SQL Server adapter by Joey Gibson that makes it suitable for actual use #394 [DeLynn Barry]
* Added that Base#find takes an optional options hash, including :conditions. Base#find_on_conditions deprecated in favor of #find with :conditions #407 [bitsweat]
* Added HasManyAssociation#count that works like Base#count #413 [intinig]
* Fixed handling of binary content in blobs and similar fields for Ruby/MySQL and SQLite #409 [xal]
* Fixed a bug in the Ruby/MySQL that caused binary content to be escaped badly and come back mangled #405 [Tobias Luetke]
* Fixed that the const_missing autoload assumes the requested constant is set by require_association and calls const_get to retrieve it.
If require_association did not set the constant then const_get will call const_missing, resulting in an infinite loop #380 [bitsweat]
* Fixed broken transactions that were actually only running object-level and not db level transactions [andreas]
* Fixed that validates_uniqueness_of used 'id' instead of defined primary key #406
* Fixed that the overwritten respond_to? method didn't take two parameters like the original #391
* Fixed quoting in validates_format_of that would allow some rules to pass regardless of input #390 [Dmitry V. Sabanin]
*1.3.0* (December 23, 2004)
* Added a require_association hook on const_missing that makes it possible to use any model class without requiring it first. This makes STI look like:
before:
require_association 'person'
class Employee < Person
end
after:
class Employee < Person
end
This also reduces the usefulness of Controller.model in Action Pack to currently only being for documentation purposes.
* Added that Base.update_all and Base.delete_all return an integer of the number of affected rows #341
* Added scope option to validation_uniqueness #349 [Kent Sibilev]
* Added respondence to *_before_type_cast for all attributes to return their string-state before they were type casted by the column type.
This is helpful for getting "100,000" back on a integer-based validation where the value would normally be "100".
* Added allow_nil options to validates_inclusion_of so that validation is only triggered if the attribute is not nil [what-a-day]
* Added work-around for PostgreSQL and the problem of getting fixtures to be created from id 1 on each test case.
This only works for auto-incrementing primary keys called "id" for now #359 [Scott Baron]
* Added Base#clear_association_cache to empty all the cached associations #347 [Tobias Luetke]
* Added more informative exceptions in establish_connection #356 [bitsweat]
* Added Base#update_attributes that'll accept a hash of attributes and save the record (returning true if it passed validation, false otherwise).
Before:
person.attributes = @params["person"]
person.save
Now:
person.update_attributes(@params["person"])
* Added Base.destroy and Base.delete to remove records without holding a reference to them first.
* Added that query benchmarking will only happen if its going to be logged anyway #344
* Added higher_item and lower_item as public methods for acts_as_list #342 [Tobias Luetke]
* Fixed that options[:counter_sql] was overwritten with interpolated sql rather than original sql #355 [bitsweat]
* Fixed that overriding an attribute's accessor would be disregarded by add_on_empty and add_on_boundary_breaking because they simply used
the attributes[] hash instead of checking for @base.respond_to?(attr.to_s). [Marten]
* Fixed that Base.table_name would expect a parameter when used in has_and_belongs_to_many joins [Anna Lissa Cruz]
* Fixed that nested transactions now work by letting the outer most transaction have the responsibilty of starting and rolling back the transaction.
If any of the inner transactions swallow the exception raised, though, the transaction will not be rolled back. So always let the transaction
bubble up even when you've dealt with local issues. Closes #231 and #340.
* Fixed validates_{confirmation,acceptance}_of to only happen when the virtual attributes are not nil #348 [dpiddy@gmail.com]
* Changed the interface on AbstractAdapter to require that adapters return the number of affected rows on delete and update operations.
* Fixed the automated timestamping feature when running under Rails' development environment that resets the inheritable attributes on each request.
*1.2.0*
* Added Base.validates_inclusion_of that validates whether the value of the specified attribute is available in a particular enumerable
object. [what-a-day]
class Person < ActiveRecord::Base
validates_inclusion_of :gender, :in=>%w( m f ), :message=>"woah! what are you then!??!!"
validates_inclusion_of :age, :in=>0..99
end
* Added acts_as_list that can decorates an existing class with methods like move_higher/lower, move_to_top/bottom. [Tobias Luetke] Example:
class TodoItem < ActiveRecord::Base
acts_as_list :scope => :todo_list_id
belongs_to :todo_list
end
* Added acts_as_tree that can decorates an existing class with a many to many relationship with itself. Perfect for categories in
categories and the likes. [Tobias Luetke]
* Added that Active Records will automatically record creation and/or update timestamps of database objects if fields of the names
created_at/created_on or updated_at/updated_on are present. [Tobias Luetke]
* Added Base.default_error_messages as a hash of all the error messages used in the validates_*_of so they can be changed in one place [Tobias Luetke]
* Added automatic transaction block around AssociationCollection.<<, AssociationCollection.delete, and AssociationCollection.destroy_all
* Fixed that Base#find will return an array if given an array -- regardless of the number of elements #270 [Marten]
* Fixed that has_and_belongs_to_many would generate bad sql when naming conventions differed from using vanilla "id" everywhere [RedTerror]
* Added a better exception for when a type column is used in a table without the intention of triggering single-table inheritance. Example:
ActiveRecord::SubclassNotFound: The single-table inheritance mechanism failed to locate the subclass: 'bad_class!'.
This error is raised because the column 'type' is reserved for storing the class in case of inheritance.
Please rename this column if you didn't intend it to be used for storing the inheritance class or
overwrite Company.inheritance_column to use another column for that information.
* Added that single-table inheritance will only kick in if the inheritance_column (by default "type") is present. Otherwise, inheritance won't
have any magic side effects.
* Added the possibility of marking fields as being in error without adding a message (using nil) to it that'll get displayed wth full_messages #208 [mjobin]
* Fixed Base.errors to be indifferent as to whether strings or symbols are used. Examples:
Before:
errors.add(:name, "must be shorter") if name.size > 10
errors.on(:name) # => "must be shorter"
errors.on("name") # => nil
After:
errors.add(:name, "must be shorter") if name.size > 10
errors.on(:name) # => "must be shorter"
errors.on("name") # => "must be shorter"
* Added Base.validates_format_of that Validates whether the value of the specified attribute is of the correct form by matching
it against the regular expression provided. [Marcel]
class Person < ActiveRecord::Base
validates_format_of :email, :with => /^([^@\s]+)@((?:[-a-z0-9]+\.)+[a-z]{2,})$/, :on => :create
end
* Added Base.validates_length_of that delegates to add_on_boundary_breaking #312 [Tobias Luetke]. Example:
Validates that the specified attribute matches the length restrictions supplied in either:
- configuration[:minimum]
- configuration[:maximum]
- configuration[:is]
- configuration[:within] (aka. configuration[:in])
Only one option can be used at a time.
class Person < ActiveRecord::Base
validates_length_of :first_name, :maximum=>30
validates_length_of :last_name, :maximum=>30, :message=>"less than %d if you don't mind"
validates_length_of :user_name, :within => 6..20, :too_long => "pick a shorter name", :too_short => "pick a longer name"
validates_length_of :fav_bra_size, :minimum=>1, :too_short=>"please enter at least %d character"
validates_length_of :smurf_leader, :is=>4, :message=>"papa is spelled with %d characters... don't play me."
end
* Added Base.validate_presence as an alternative to implementing validate and doing errors.add_on_empty yourself.
* Added Base.validates_uniqueness_of that alidates whether the value of the specified attributes are unique across the system.
Useful for making sure that only one user can be named "davidhh".
class Person < ActiveRecord::Base
validates_uniqueness_of :user_name
end
When the record is created, a check is performed to make sure that no record exist in the database with the given value for the specified
attribute (that maps to a column). When the record is updated, the same check is made but disregarding the record itself.
* Added Base.validates_confirmation_of that encapsulates the pattern of wanting to validate a password or email address field with a confirmation. Example:
Model:
class Person < ActiveRecord::Base
validates_confirmation_of :password
end
View:
<%= password_field "person", "password" %>
<%= password_field "person", "password_confirmation" %>
The person has to already have a password attribute (a column in the people table), but the password_confirmation is virtual.
It exists only as an in-memory variable for validating the password. This check is performed both on create and update.
* Added Base.validates_acceptance_of that encapsulates the pattern of wanting to validate the acceptance of a terms of service check box (or similar agreement). Example:
class Person < ActiveRecord::Base
validates_acceptance_of :terms_of_service
end
The terms_of_service attribute is entirely virtual. No database column is needed. This check is performed both on create and update.
NOTE: The agreement is considered valid if it's set to the string "1". This makes it easy to relate it to an HTML checkbox.
* Added validation macros to make the stackable just like the lifecycle callbacks. Examples:
class Person < ActiveRecord::Base
validate { |record| record.errors.add("name", "too short") unless name.size > 10 }
validate { |record| record.errors.add("name", "too long") unless name.size < 20 }
validate_on_create :validate_password
private
def validate_password
errors.add("password", "too short") unless password.size > 6
end
end
* Added the option for sanitizing find_by_sql and the offset parts in regular finds [Sam Stephenson]. Examples:
Project.find_all ["category = ?", category_name], "created ASC", ["? OFFSET ?", 15, 20]
Post.find_by_sql ["SELECT * FROM posts WHERE author = ? AND created > ?", author_id, start_date]
* Fixed value quoting in all generated SQL statements, so that integers are not surrounded in quotes and that all sanitation are happening
through the database's own quoting routine. This should hopefully make it lots easier for new adapters that doesn't accept '1' for integer
columns.
* Fixed has_and_belongs_to_many guessing of foreign key so that keys are generated correctly for models like SomeVerySpecialClient
[Florian Weber]
* Added counter_sql option for has_many associations [bitsweat]. Documentation:
<tt>:counter_sql</tt> - specify a complete SQL statement to fetch the size of the association. If +:finder_sql+ is
specified but +:counter_sql+, +:counter_sql+ will be generated by replacing SELECT ... FROM with SELECT COUNT(*) FROM.
* Fixed that methods wrapped in callbacks still return their original result #260 [bitsweat]
* Fixed the Inflector to handle the movie/movies pair correctly #261 [Scott Baron]
* Added named bind-style variable interpolation #281 [Michael Koziarski]. Example:
Person.find(["id = :id and first_name = :first_name", { :id => 5, :first_name = "bob' or 1=1" }])
* Added bind-style variable interpolation for the condition arrays that uses the adapter's quote method [Michael Koziarski]
Before:
find_first([ "user_name = '%s' AND password = '%s'", user_name, password ])]
find_first([ "firm_id = %s", firm_id ])] # unsafe!
After:
find_first([ "user_name = ? AND password = ?", user_name, password ])]
find_first([ "firm_id = ?", firm_id ])]
* Added CSV format for fixtures #272 [what-a-day]. (See the new and expanded documentation on fixtures for more information)
* Fixed fixtures using primary key fields called something else than "id" [dave]
* Added proper handling of time fields that are turned into Time objects with the dummy date of 2000/1/1 [HariSeldon]
* Added reverse order of deleting fixtures, so referential keys can be maintained #247 [Tim Bates]
* Added relative path search for sqlite dbfiles in database.yml (if RAILS_ROOT is defined) #233 [bitsweat]
* Added option to establish_connection where you'll be able to leave out the parameter to have it use the RAILS_ENV environment variable
* Fixed problems with primary keys and postgresql sequences (#230) [Tim Bates]
* Added reloading for associations under cached environments like FastCGI and mod_ruby. This makes it possible to use those environments for development.
This is turned on by default, but can be turned off with ActiveRecord::Base.reload_dependencies = false in production environments.
NOTE: This will only have an effect if you let the associations manage the requiring of model classes. All libraries loaded through
require will be "forever" cached. You can, however, use ActiveRecord::Base.load_or_require("library") to get this behavior outside of the
auto-loading associations.
* Added ERB capabilities to the fixture files for dynamic fixture generation. You don't need to do anything, just include ERB blocks like:
david:
id: 1
name: David
jamis:
id: 2
name: Jamis
<% for digit in 3..10 %>
dev_<%= digit %>:
id: <%= digit %>
name: fixture_<%= digit %>
<% end %>
* Changed the yaml fixture searcher to look in the root of the fixtures directory, so when you before could have something like:
fixtures/developers/fixtures.yaml
fixtures/accounts/fixtures.yaml
...you now need to do:
fixtures/developers.yaml
fixtures/accounts.yaml
* Changed the fixture format from:
name: david
data:
id: 1
name: David Heinemeier Hansson
birthday: 1979-10-15
profession: Systems development
---
name: steve
data:
id: 2
name: Steve Ross Kellock
birthday: 1974-09-27
profession: guy with keyboard
...to:
david:
id: 1
name: David Heinemeier Hansson
birthday: 1979-10-15
profession: Systems development
steve:
id: 2
name: Steve Ross Kellock
birthday: 1974-09-27
profession: guy with keyboard
The change is NOT backwards compatible. Fixtures written in the old YAML style needs to be rewritten!
* All associations will now attempt to require the classes that they associate to. Relieving the need for most explicit 'require' statements.
*1.1.0* (34)
* Added automatic fixture setup and instance variable availability. Fixtures can also be automatically
instantiated in instance variables relating to their names using the following style:
class FixturesTest < Test::Unit::TestCase
fixtures :developers # you can add more with comma separation
def test_developers
assert_equal 3, @developers.size # the container for all the fixtures is automatically set
assert_kind_of Developer, @david # works like @developers["david"].find
assert_equal "David Heinemeier Hansson", @david.name
end
end
* Added HasAndBelongsToManyAssociation#push_with_attributes(object, join_attributes) that can create associations in the join table with additional
attributes. This is really useful when you have information that's only relevant to the join itself, such as a "added_on" column for an association
between post and category. The added attributes will automatically be injected into objects retrieved through the association similar to the piggy-back
approach:
post.categories.push_with_attributes(category, :added_on => Date.today)
post.categories.first.added_on # => Date.today
NOTE: The categories table doesn't have a added_on column, it's the categories_post join table that does!
* Fixed that :exclusively_dependent and :dependent can't be activated at the same time on has_many associations [bitsweat]
* Fixed that database passwords couldn't be all numeric [bitsweat]
* Fixed that calling id would create the instance variable for new_records preventing them from being saved correctly [bitsweat]
* Added sanitization feature to HasManyAssociation#find_all so it works just like Base.find_all [Sam Stephenson/bitsweat]
* Added that you can pass overlapping ids to find wi
