Seems to be a bug. I can't dig into the core of it (since too many
models), but here is what I know.
I have a model user, which has primary key :id.
I also have a model of action. Two users interact with each other
through the model of action. Say, one user sends a comment to the
other. So, action model has primary key :id, and also :sender_id
and :receiver_id, which are ids of sender and receiver,
correspondingly. There is also a concept of rating. Receiver can rate
the sender for his comment. That is, rating doesn't have a primary
key, yet it has :user_id (which is the id of receiver) and :action_id.
The model for ACTION has:
belongs_to sender, :class_name => 'User', :foreign_key => :sender_id
belongs_to receiver, :class_name => 'User', :foreign_key
The model for USER has:
has_many :sent_actions, :class_name => 'Action', :foreign_key
has_many :received_actions, :class_name => 'Action', :foreign_key
The model for RATING has:
Now the funniest part. When I try to save new rating, it's not saved,
while rating has belongs_to :action. If this line is commented, then
everything is ok - rating is saved and rating.action_id is in place in
I dug into into save! of the ActiveRecord class and put a "raise
'testing...'" there instead of its usual code. Now, if
belongs_to :action is inside the model, then save! doesn't fire off
with an error, which means that rails doesn't even go inside save!. If
belongs_to :action is commented, then 'testing...' appear on the
screen, while trying to save a rating.
Did anyone bump into anything similar? How to override? Or it's a bug
and I need to forget about it and find working workaround?
