I have multiple belongs_to relationships to the same model. Modeling messages between two users as follows (in the Message model):
belongs_to :to, :class_name => 'User', :foreign_key => 'to_id'
belongs_to :from, :class_name => 'User', :foreign_key => 'from_id'
attr_accessible :to, :from # ...
The corresponding has_many calls are in the User model. Everything works in the spec and the console as I need it to, with the exception of the following deprecation warning (for both from_id and to_id):
DEPRECATION WARNING: You're trying to create an attribute `from_id'. Writing arbitrary attributes on a model is deprecated. Please just use `attr_writer`
The relevant spec follows:
it "can associate users" do
User.delete(:all)
ufrom = FactoryGirl.create(:DrKevorkian)
ufrom.save!
uto = FactoryGirl.create(:JohnSmith)
uto.save!
m = Message.new
m.from = ufrom # <-- Warning here
m.to = uto # <-- Warning here
m.save
m.from.id.should == ufrom.id
m.to.id.should == uto.id
end
It seems to me the warning is happening as a result of the belongs_to association -- is there a cleaner/better way to do this?
Thanks very much.
