* Set the inverse when association queries are refinedJon Leighton2013-05-103-1/+20
| | | | | | | | | | | | | | | | | | | | | | | | | Suppose Man has_many interests, and inverse_of is used. Man.first.interests.first.man will correctly execute two queries, avoiding the need for a third query when Interest#man is called. This is because CollectionAssociation#first calls set_inverse_instance. However Man.first.interests.where("1=1").first.man will execute three queries, even though this is obviously a subset of the records in the association. This is because calling where("1=1") spawns a new Relation object from the CollectionProxy object, and the Relation has no knowledge of the association, so it cannot set the inverse instance. This commit solves the problem by making relations spawned from CollectionProxies return a new Relation subclass called AssociationRelation, which does know about associations. Records loaded from this class will get the inverse instance set properly. Fixes #5717. Live commit from La Conf! :sparkles:
* extracted piece of code into a methodNeeraj Singh2013-05-081-13/+12
| | | | | | | | | | | | | | | | In order to fix #10421 I need to enable merge to take an option so that relations could be merged without making the last where condition to win. That fix would forever reside in 4-0-stable branch and would not be merged to master since using scope without lambda has been deprecated. In this commit I have extracted code into a method and I think it makes code look better. Hence the request to merge it in both master and 4-0-stable. If there is any concern then this code can be merged only in 4-0-stable and that would be fine too.

* Handle other pk types in PostgreSQL gracefully.Patrick Robertson2013-05-071-2/+6
| | | | | | | | | | | | | | In #10410 it was noted that you can no longer create PK's with the type of bigserial in PostgreSQL in 4.0.0.rc1. This is mostly because the newer adapter is checking for column type with the id column instead of just letting it pass through like it did before. Side effects: You may just create a PK column of a type that you really don't want to be your PK. As far as I can tell this was allowed in 3.2.X and perhaps an exception should be raised if you try and do something extremely dumb.

| | | | | | | | | | | | | | | | | | counter cache At present, calling destroy multiple times on the same record results in the belongs_to counter cache being decremented multiple times. With this change the record is checked for whether it is already destroyed prior to decrementing the counter cache.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | fixes bug introduced by #3329 These are the conditions necessary to reproduce the bug: - For an association, autosave => true. - An association record is being destroyed - A new association record is being created. - There is a unique index one of the association's fields. - The record being created has the same value as the record being destroyed on the indexed field. Before, the deletion of records was postponed until after all insertions/saves. Therefore the new record with the identical value in the indexed field caused a non-unique value error to be thrown at the database level. With this fix, the deletions happen first, before the insertions/saves. Therefore the record with the duplicate value is gone from the database before the new record is created, thereby avoiding the non-uniuqe value error.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | activerecord/lib/active_record/associations.rb states: # [association=(associate)] # Assigns the associate object, extracts the primary key, sets it as the foreign key, # and saves the associate object. Since commit 42dd5d9f2976677a4bf22347f2dde1a8135dfbb4 to fix #7191, this is no longer the case if the associate has changed, but is the same object. For example: # Pirate has_one :ship pirate = Pirate.create!(catchphrase: "A Pirate") ship = pirate.build_ship(name: 'old name') ship.save! ship.name = 'new name' pirate.ship = ship That last line should trigger a save. Although we are not changing the association, the associate (ship) has changed.
