Is this the proper relationship for this to work? It looks right to me...
What I want to do is add notes to a student through the Attendance Edit form
class Attendance < ActiveRecord::Base
belongs_to :student
accepts_nested_attributes_for :student
has_many :notes, through: :student
accepts_nested_attributes_for :notes
end
class Student < ActiveRecord::Base
# Also used through Attendance Edit
has_many :attendances, dependent: :destroy
has_many :notes, dependent: :destroy
accepts_nested_attributes_for :notes, allow_destroy: true
end
class Note < ActiveRecord::Base
belongs_to :student
end
