FormulairesController #create中的ActiveModel :: ForbiddenAttributesError

Posted 2021-04-19

我按照本教程了解嵌套表单（http://railscasts.com/episodes/196-nested-model-form-part-1?autoplay=true）。我必须创建表单/问题/答案。它可以用于表单和问题但是当我想在我的数据库中插入答案时它不起作用。

我尝试了两种创建方法：

def create
  @formulaire = current_user.formulaires.new(formulaire_params)
  if @formulaire.save    
    redirect_to @formulaire, notice: "Votre formulaire a bien été crée"   
  else     
    render :new
   end
 end

和＃@ form = Form.new（params [：form]）

我的formulaire_params方法：

    def formulaire_params
      params.require(:formulaire).permit(:name, :description,       questions_attributes: [:id,:nom, :typequestion,
      answer_attributes:[:id, :content]]) if params[:formulaire]
end

在我看来，我有一个带有fields_for的表单：带有text_field内容的答案，但我的数据库中没有任何内容。

谢谢

答案

 class Formulaire < ActiveRecord::Base

belongs_to :user
has_many :questions, dependent: :destroy
accepts_nested_attributes_for :questions, :reject_if => lambda { |a|       a[:nom].blank? }, :allow_destroy => true


 validates :name, presence: true
 validates :description, presence: true

end

class Question < ActiveRecord::Base
belongs_to :formulaire
has_many :answers, :dependent => :destroy
 accepts_nested_attributes_for :answers, :allow_destroy => true

 #self.inheritance_column = nil
enum typequestion: [:reponse_courte, :choix_multiple, :choix_simple]

end

当我创建提交表单时的日志：
