Changes: * Set config.active_record.timestamped_migrations = false to have migrations with numeric prefix instead of UTC timestamp. #446. * Fixed that create database statements would always include "DEFAULT NULL" [#334] * change_column_default preserves the not-null constraint. #617 * Add :tokenizer option to validates_length_of to specify how to split up the attribute string. #507. Example : # Ensure essay contains at least 100 words. validates_length_of :essay, :minimum => 100, :too_short => "Your essay must be at least %d words."), :tokenizer => lambda {|str| str.scan(/\w+/) } * Always treat integer :limit as byte length. #420 * Partial updates don't update lock_version if nothing changed. #426 * Fix column collision with named_scope and :joins. #46 * db:migrate:down and :up update schema_migrations. #369 * PostgreSQL: support :conditions => [':foo::integer', { :foo => 1 }] without treating the ::integer typecast as a bind variable. * MySQL: rename_column preserves column defaults. #466 * Add :from option to calculations. #397 * Add :validate option to associations to enable/disable the automatic validation of associated models. Resolves #301. * PostgreSQL: use 'INSERT ... RETURNING id' for 8.2 and later. * Added SQL escaping for :limit and :offset in MySQL |
