AR Callbacks and associations

rubyonrails-talk

Hello,

I have this model in Rails 2.0: class Contact < ActiveRecord::Base   before_save :update_contact_user

  belongs_to :user

belongs_to :contact_user, :class_name=>'User', :foreign_key=>'contact_user_id'

  validates_presence_of :user, :fullname, :email   validates_as_email :email   validate_phone :home_tel, :mobile_tel, :office_tel

private   def update_contact_user     #check if some user matches the email entered     cuser = User.find :first, :conditions=>["email = ?", email]     contact_user = cuser if cuser   end

end

The callback is called correctly and finds a user, but for some reason the association is not updated. If I do the same code in the calling method (just before I call 'save') then it is working. Any guess? Am I missing something?

Thank you, Julien.

in update_contact_user method, contact_user is a local variable.

Try : self.contact_user = cuser if cuser

Thanks, Julien.
