I'm having problems building an association that is a has_many :through
with conditions. I have this model:
class Contact < AR
has_many :group_contacts
has_many :groups, :through => :group_contacts, :conditions => {:groups => {:published => true}}
end
problem happens when I try to instantiate a group from a contact. With the above syntax, I get an error:
contact.groups.build
=> ActiveRecord::UnknownAttributeError: unknown attribute: groups
But when I use the following syntax it works:
has_many :groups, :through => :group_contacts, :conditions => ['groups.published = ?', true]
contact.groups.build
=> #<Group id: nil, name: nil, description: nil, created_at: nil, updated_at: nil, published: true>
I see a reference to the exact problem in this question. It is said a ticket would be filed for this bug (back in pre- rai开发者_如何学编程ls 3 versions). I can't find anything however on rails 3.0.x
.
I'm using 3.0.8. Has anyone else found this issue?
Further Notes:
I've also found that when I'm building groups, it actually ignores my conditions on the association when building. The only reason my above build had published => true
is because it's the default in the db.
This seems like a regression, can anyone else verify this?
has_many :groups, :through => :group_contacts, :conditions => {:published => true}
or
has_many :groups, :through => :group_contacts, :conditions => {"groups.published" => true}
