* Relation#from to accept other Relation objectsRadoslav Stankov2012-05-172-6/+31
| | | | Record.from("(#{sub_query.to_sql})") -> Record.from(sub_query) Record.from("(#{sub_query.to_sql}) a") -> Record.from(sub_query, :a)
* assuming there is only one column, we can simplify the type cast loopAaron Patterson2012-05-161-7/+6

* MySQL returns "SUM(DISTINCT(credit_limit))" as the column name unlessAaron Patterson2012-05-161-4/+11

* CollectionProxy < RelationJon Leighton2012-05-113-28/+33
| | | | | | | | | | | | | | | | | | | | | This helps bring the interfaces of CollectionProxy and Relation closer together, and reduces the delegation backflips we need to perform. For example, first_or_create is defined thus: class ActiveRecord::Relation def first_or_create(...) first || create(...) end end If CollectionProxy < Relation, then post.comments.first_or_create will hit the association's #create method which will actually add the new record to the association, just as post.comments.create would. With the previous delegation, post.comments.first_or_create expands to post.comments.scoped.first_or_create, where post.comments.scoped has no knowledge of the association.
