Here’s the code: = form_for @form do |f| = f.fields_for :questions do |q| %p

  • 0

Here’s the code:

= form_for @form do |f|
  = f.fields_for :questions do |q|
    %p
      = q.object.content
      = q.fields_for :answers do |a|
        %p= a.text_area :content

What the name attribute on the text_area should be form[questions_attributes][0][answer_attribute][content] but it’s showing. form[questions_attributes][0][answers][content].

Here’s my models.

# answer.rb
  belongs_to :question

# question.rb
  has_one :answer
  accepts_nested_attributes_for :answer

# form.rb
  has_many :questions, :order => 'position ASC'
  accepts_nested_attributes_for :questions

So what I’m getting in the log is WARNING: Can't mass-assign protected attributes: answers

Any help would be greatly appreciated. Thanks!

When I add answers to attr_accessible in question.rb I get ActiveRecord::UnknownAttributeError (unknown attribute: answers)

    I left everything in my models as is but I did this to the form:

     = f.fields_for :questions do |q|
    = q.fields_for :answer, q.object.answer do |a|
      = a.hidden_field :question_id, :value => q.object.id
      = a.hidden_field :form_id, :value => @form.id
      %p
        = a.label :content, q.object.content
        %br
        = a.text_area :content

    And it works perfectly. If there’s any refining or anything feel free to comment on this.
