[PATCH] [TEST] Short hand declaration style for lock_version

Reported by: lawrence Assigned to: core
Priority: normal Milestone: 2.x
Component: ActiveRecord Version: edge
Severity: normal Keywords: patch test
Cc:

Description

Like the shorthand notation for timestamps, add a short hand notation for lock_version for optimistic locking. E.g.: 

    create_table :products do |t|
      t.lock_version
    end

This would add column lock_version as integer with default 0

  • attachment lock_version.patch added.

Added test: moved creation of people table from .sql files to schema.rb file. Note that the definition of the table is now: 

  create_table :people, :force => true do |t|
    t.string :first_name    
    t.lock_version
  end

and that the existing locking_test.rb, method OptimisticLockingTest uses the lock_version column of table people.

Note: sqlserver_lock_version.patch must be patched against sqlserver adapter plugin.
