undefined method 'state'

I can't imagine what I'm trying to do is complicated at all in Rails. Yet, I am now getting this error: undefined method `state' for :StudentFailState:Symbol.

student.rb has_one :student_fail attr_accessor :student_fail_attribute

#controller def student_fail @student = @student.find params[:id]

def update_student_fail   @student.build_student_fail params[:student][:student_fail_attribute]   if @student.save

#view            form_for @student do |f| f.collection_select( :student_fail_attribute, params[:StudentFailState.state], params[:id], params[:key]) end

true is an attribute of the StudentFailState table. There are three records in that table. So in the dropdown it will display the text (key attribute) of each table and each table will have an id.

Any suggestions? Thanks.

This gives undefined method join error:

form_for @student do |f| f.collection_select(:student_fail_attribute, StudentFailState.all, :id, :key) end

Yes. Put Rails aside for a few days and focus on learning Ruby. You're making an elementary syntax error. If you can't see it, then you don't yet know Ruby well enough to use Rails profitably.

Best,
