Hi,

this student. I did the simple code below, and this is the error i get.
I can''t see what i did wrong...

Or, in the controller code that you didn''t show, pluck the tag_attributes out: tag_attributes = params[:student].delete(''tag_attributes'') before you call @student.update_attributes(params[:student]) and add a call to: @student.tag_attributes = tag_attributes -Rob> > validates_uniqueness_of :cb_id > > def tag_attributes=(tags) > splits = tags.split('','') > splits.each do |tag| > Tag.build(tag) > end > end > end > #END > > Thanks for your help > Greg > -- > Posted via http://www.ruby-forum.com/. > > -- > You received this message because you are subscribed to the Google > Groups "Ruby on Rails: Talk" group. > To post to this group, send email to rubyonrails- > talk-/JYPxA39Uh5TLH3MbocFF+G/Ez6ZCGd0@public.gmane.org > To unsubscribe from this group, send email to rubyonrails-talk+unsubscribe-/JYPxA39Uh5TLH3MbocFFw@public.gmane.org > . > For more options, visit this group at http://groups.google.com/group/rubyonrails-talk?hl=en > . >Rob Biedenharn http://agileconsultingllc.com Rob-xa9cJyRlE0mWcWVYNo9pwxS2lgjeYSpx@public.gmane.org -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

Re: Can''t mass-assign these protected attributes: tag_attributes
I think you need to add :tag_attributes to attr_accessible in your model – would this fix the problem?
