* Ensure calling first/last with options correctly set inverse associationCarlos Antonio da Silva2012-11-011-1/+3
| | | | Also related to #8087. Thanks @al2o3cr.
* Fix issue with collection associations and first(n)/last(n)Carlos Antonio da Silva2012-11-011-1/+1
| | | | | | | | | | | | | | | | | When calling first(n) or last(n) in a collection, Active Record was improperly trying to set the inverse of instance in case that option existed. This change was introduced by fdf4eae506fa9895e831f569bed3c4aa6a999a22. In such cases we don't need to do that "manually", since the way collection will be loaded will already handle that, so we just skip setting the inverse association when any argument is given to first(n)/last(n). The test included ensures that these scenarios will have the inverse of instance set properly. Fixes #8087, Closes #8094.
* Fix has_many assocation w/select load after createErnie Miller2012-10-121-1/+1
| | | | | | | | | | If you create a new record via a collection association proxy that has not loaded its target, and which selects additional attributes through the association, then when the proxy loads its target, it will inadvertently trigger a deprecation notice during attribute writing when CollectionAssociation#merge_target_lists attempts to do its thing, since the newly loaded records will possess attributes the created record does not.
* Eager autoload Preloader classesJohn Firebaugh2012-10-101-10/+14
| | | | | | Without eager autoloading, these would be autoloaded only when #preloader_for is called, which is too late in threaded applications.

* Do not use update_column where update_attribute is not interchangeableRafael Mendonça França2012-08-151-1/+1
| | | | | | | | | | | | Revert "Deprecate update_attribute." This reverts commit b081f6b59fb3f15d12043072ad9b331ffd2bc56e. Reason: Since the new deprecation policy we removed the deprecation of update_attribute but we didn't reverted the changes to use update_column. Fixes #7306

| | | | | | | | | | This reverts commit a79bfa92e7bdc31b346d13ee5447d3fdac382bfb. Conflicts: activerecord/CHANGELOG.md We shouldn't introducing deprecations in point releases. It will be deprecated in 4.0 instead.
* Deprecate :finder_sql, :counter_sql, :insert_sql, :delete_sql.Jon Leighton2012-07-202-0/+21
|
* Deprecate update_attribute.Steve Klabnik2012-06-141-1/+1
| | | | | | | | | | | Historically, update_attribute and update_attributes are similar, but with one big difference: update_attribute does not run validations. These two methods are really easy to confuse given their similar names. Therefore, update_attribute is being deprecated in favor of update_column, and will be removed in Rails 4.

* Restore behavior of Active Record 3.2.3 scopesAndrew White2012-06-011-3/+2
| | | | | | | | | | | | | | A series of commits relating to preloading and scopes caused a regression. Cloning the relation calls initialize_copy which resets a number of instance variables to nil. Without this the scope thinks that it is already loaded when it is called again. Reverts the following commits: 13f1401a6cf0266a3b0a91b173f976db2d4e50f3 8491740ca5361ba9df20e1c8b906c709f5bfbc12 dffbb521a0d00c8673a3ad6e0e8ff526f32daf4e Fixes #6575, #6576 & #6577

* Ensure that CollectionAssociation#replace returns proper targetPiotr Sarnacki2012-05-191-1/+1
| | | | | | | | The fix commited in e2a070c was returning the `new_target`, as a try to return whatever user replaced association with. The problem is, the resulting association target may be ordered differently. In such case we want to return the target that will be later used for that association.

| | | | | | | | Causes a subtle regression where record.reload includes the default scope. Hard to reproduce in isolation. Seems like the relation is getting infected by some previous usage. This reverts commit dffbb521a0d00c8673a3ad6e0e8ff526f32daf4e.

|\ | | | | association methods are now generated in modules
| * avoid warningsJosh Susser2011-11-276-15/+15
| | | | | | | | | | | | | | This change uses Module.redefine_method as defined in ActiveSupport. Making Module.define_method public would be as clean in the code, and would also emit warnings when redefining an association. That is pretty messy given current tests, so I'm leaving it for someone else to decide what approach is better.

| * association methods are now generated in modulesJosh Susser2011-11-157-30/+25
| | | | | | | | | | | | | | | | | | | | Instead of generating association methods directly in the model class, they are generated in an anonymous module which is then included in the model class. There is one such module for each association. The only subtlety is that the generated_attributes_methods module (from ActiveModel) must be forced to be included before association methods are created so that attribute methods will not shadow association methods.
