Title
Body
I have photos that belong to collections and users. Photos always belong to a user, but may not be assigned to a collection. In my controller, this works perfectly: @collection_photos = Photo.where( :collection => @collection, :user => current_user ) However, this fails... @other_photos = Photo.where( :collection => nil, :user => current_user ) ...but this works: @other_photos = Photo.where( :collection_id => nil, :user => current_user ) When collection is set to nil I get this error message: No attribute named 'collection' exists for table photos . If I pass an object, it knows to search for collection_id from the symbol :collection , but if I don't pass an object it doesn't seem to be aware of the association. Am I understanding this correctly? Could anyone explain a little better why :collection=>nil doesn't work?
