I have the following relationships:
class User < ActiveRecord::Base
has_many :pictures
end
class Picture < ActiveRecord::Base
belongs_to :user
end
And now I hace the following code:
@user = User.find params[:id]
@picture = @user.pictures.new params[:picture]
But for user_id to be saved in my pictures db I have to add this line of code:
@picture.user_id = @user.id # should not need this... why?
That makes no sense. I though all this time the foreign key was
automatically stored. Am I going crazy?
Thanks for your input :-).
Your Friend,
John

Are you sure... it works and everything so thanks but according to docs build is protected method and we should use new instead... is this new?

You are right! But it does say here that build is protected: http://api.rubyonrails.com/classes/ActiveRecord/Associations/ClassMethods/JoinDependency.html#M000539 On 9/19/06, Jeremy Kemper <jeremy-w7CzD/W5Ocjk1uMJSBkQmQ@public.gmane.org> wrote:> > > > On 9/19/06, John Kopanas <kopanas-Re5JQEeQqe8AvxtiuMwx3w@public.gmane.org> wrote: > > Are you sure... it works and everything so thanks but according to > > docs build is protected method and we should use new instead... is > > this new? > > > See the has_many docs.
