* Revert "Raise error on unknown primary key."Jon Leighton2011-10-051-3/+3
| | | | This reverts commit ee2be435b1e5c0e94a4ee93a1a310e0471a77d07.
* Raise error on unknown primary key.Jon Leighton2011-10-051-3/+3
| | | | | If we don't have a primary key when we ask for it, it's better to fail fast. Fixes GH #2307.
* Rename first_or_new to first_or_initialize.Jon Leighton2011-09-131-2/+1
| | | | | For consistency with find_or_initialize_by. Also remove first_or_build alias.
* Using more precise method signatures for AR::Relation#first_or_create family ↵Andrés Mejía2011-09-061-6/+6
| | | | of methods.
* Adding first example with no arguments to AR::Relation#first_or_create and ↵Andrés Mejía2011-09-061-15/+15
| | | | removing examples that create several users at the same time (this is confusing and not really helpful).
* Adding first_or_create, first_or_create!, first_or_new and first_or_build to ↵Andrés Mejía2011-08-301-0/+43
| | | | | | | | | | Active Record. This let's you write things like: User.where(:first_name => "Scarlett").first_or_create!(:last_name => "Johansson", :hot => true) Related to #2420.
* Refactor building the update managerJon Leighton2011-08-151-5/+6

|
* Make it the responsibility of the connection to hold onto an ARel visitor ↵Jon Leighton2011-08-081-7/+6
| | | | for generating SQL. This improves the code architecture generally, and solves some problems with marshalling. Adapter authors please take note: you now need to define an Adapter.visitor_for method, but it degrades gracefully with a deprecation warning for now.
* Bring back the ability to provide :order for update_all.thedarkone2011-07-251-9/+5
|
* Foo.joins(:bar).includes(:bar) should result in a single query with :bar as ↵Jon Leighton2011-07-091-1/+11

| | | | test surrounding create_with(nil) behavior
* Fix issue #1272Brian Mathiyakom2011-06-011-1/+1
