* Delegate all calculations to the scope.Jon Leighton2012-11-091-4/+2
| | | | | | | So that the scope may be a NullRelation and return a result without executing a query. Fixes #7928
* CollectionProxy#pluck issues no query for a new_record? ownerJon Leighton2012-11-091-0/+4
| | | | | | | Fixes #8102. I couldn't find a nicer way to deal with this than delegate the call to #scope, which will be a NullRelation when we want it to be.
* Nullify the relation at a more general level.Jon Leighton2012-11-091-4/+3
| | | | | | | | | | | | | | | This allows us to avoid hacks like the "return 0 if owner.new_record?" in #count (which this commit removes). Also, the relevant foreign key may actually be present even on a new owner record, in which case we *don't* want a null relation. This logic is encapsulated in the #null_scope? method. We also need to make sure that the CollectionProxy is not 'infected' with the NullRelation module, or else the methods from there will override the definitions in CollectionProxy, leading to incorrect results. Hence the nullify: false option to CollectionAssociation#scope. (This feels a bit nasty but I can't think of a better way.)
* Relations built off collection associations with an unsaved owner should be ↵Jon Leighton2012-11-091-2/+3
| | | | | | | | | | null relations For example, the following should not run any query on the database: Post.new.comments.where(body: 'omg').to_a # => [] Fixes #5215.

* Add CollectionProxy#scopeJon Leighton2012-08-011-1/+5
| | | | | | | | | | | | | | | | This can be used to get a Relation from an association. Previously we had a #scoped method, but we're deprecating that for AR::Base, so it doesn't make sense to have it here. This was requested by DHH, to facilitate code like this: Project.scope.order('created_at DESC').page(current_page).tagged_with(@tag).limit(5).scoping do @topics = @project.topics.scope @todolists = @project.todolists.scope @attachments = @project.attachments.scope @documents = @project.documents.scope end
* Use explicit delegationsJon Leighton2012-08-011-119/+79
| | | | | | | This makes it easier to see what the documentation refers to. It also means that we are not doing unnecessary work for delegations that have no args / splats / block / etc.

* Deprecate ActiveRecord::Base.scoped.Jon Leighton2012-07-271-5/+1
| | | | | | | It doesn't serve much purpose now that ActiveRecord::Base.all returns a Relation. The code is moved to active_record_deprecated_finders.

* | Add support for CollectionAssociation#delete by Fixnum or StringFrancesco Rodriguez2012-05-281-0/+26
|/ | | | | | | | | | | | | | | | | | | | | | | | I found the next issue between CollectionAssociation `delete` and `destroy`. class Person < ActiveRecord::Base has_many :pets end person.pets.destroy(1) # => OK, returns the destroyed object person.pets.destroy("2") # => OK, returns the destroyed object person.pets.delete(1) # => ActiveRecord::AssociationTypeMismatch person.pets.delete("2") # => ActiveRecord::AssociationTypeMismatch Adding support for deleting with a fixnum or string like `destroy` method.
