TheBreeze / shadow

Provides a history of attribute and association updates for models. This coincides with a versioning system (such as acts_as_versioned). When used in tandem, you get both a history of changes and a history of what changed.

4 - RSpec test coverage (currently only tested in application originally written for)
5
6 - Need to define create_attribute_shadow_table and create_association_shadow_table, which will generate a migration for you.
7 Usage example:
8 Vacation.create_attribute_shadow_table # options include :attachments => [:user, ...] <- creates user_id
9 # Resulting table: vacation_attribute_shadows
10
11 Vacation.create_association_shadow_table # options include :attachments => [:user, ...] <- creates user_id
12 # Resulting table: vacation_association_shadows
13
14 # And (already defined)
15 Vacation.create_shadow_tables # subsequently calls create_shadow_attributes_table and create_shadow_associations_table
16
17 # This should generate:
18 class CreateVacationShadowTables < ActiveRecord::Migration
19 def self.up
20 create_table :vacation_attribute_shadows do |t|
21 t.text :updated_attributes
22 t.integer :version, :vacation_id, :user_id
23
24 t.timestamps
25 end
26
27 create_table :vacation_association_shadows do |t|
28 t.string :association, :action
29 t.integer :record_id, :record_version, :vacation_id, :user_id
30
31 t.timestamps
32 end
33 end

35 def self.down
36 drop_table :vacation_attribute_shadows
37 drop_table :vacation_association_shadows
38 end
