Replaces mini_record-compat. Define table structure (columns and indexes) inside your ActiveRecord models like you can do in migrations.

ActiveRecordInlineSchema

Define table structure (columns and indexes) inside your ActiveRecord models like you can do in migrations. Also similar to DataMapper inline schema syntax.

Specify columns like you would with ActiveRecord migrations and then run .auto_upgrade! Based on the mini_record gem from Davide D'Agostino, it adds fewer aliases, doesn't create timestamps and relationship columns automatically.

You don't have to be connected to the database when you run the DSL methods.

Production use

Over 2 years in Brighter Planet's environmental impact API and reference data service.

Lots and lots of use in the earth library.

Examples

class Breed < ActiveRecord::Base
  col :species_name
  col :weight, :type => :float
  col :weight_units
end
Breed.auto_upgrade!

class Airport < ActiveRecord::Base
  self.primary_key = "iata_code"
  belongs_to :country, :foreign_key => 'country_iso_3166_code', :primary_key => 'iso_3166_code'
  col :iata_code
  col :name
  col :city
  col :country_name
  col :country_iso_3166_code
  col :latitude, :type => :float
  col :longitude, :type => :float
end
Airport.auto_upgrade!

class ApiResponse < ActiveRecord::Base
  # store with:    self.raw_body = Zlib::Deflate.deflate(body, Zlib::BEST_SPEED)
  # retrieve with: Zlib::Inflate.inflate(raw_body).force_encoding 'UTF-8'
  # just an idea!
  col :raw_body, :type => 'varbinary(16384)'
end
ApiResponse.auto_upgrade!

# you can also do this
ApiResponse.auto_upgrade! :dry_run => true

# this won't delete columns that it doesn't know about
ApiResponse.auto_upgrade! :gentle => true

Massive thanks to DAddYE, who you follow on twitter @daddye and look at his site at daddye.it

TODO

  • make the documentation as good as mini_record
  • investigate switching back to ActiveRecord::ConnectionAdapters::TableDefinition as a way of holding column and index info

History

Forked from mini_record version v0.2.1 - thanks @daddye! See CHANGELOG for a rough outline of the differences.
