Question

I am working with Rails and I cannot seem to get past this error. A course has many notes and a note belongs to course.

The error I get is:

Can’t mass-assign protected attributes: course

Here is my course.rb

class Course < ActiveRecord::Base
belongs_to :semester
has_many :notes, :dependent => :destroy

attr_accessible :course_name, :course_number, :instructor, :instructor_email, :class_meets, 
                :class_starts, :semester_id
end

note.rb

class Note < ActiveRecord::Base
belongs_to :course
attr_accessor :course_name, :course_id
attr_accessible :title, :date, :body, :extra, :course_name, :course_id 
end

notes/_form.html.erb (User can select a course and create notes)

<%= f.select("course", Course.find(:all).collect {|c| [c.course_name, c.id]})%>

Is there anyway to resolve this error?

Answer 1

you need to add

attr_accessible :course

inside your Note.rb
