중첩 된 리소스를 만들지 않기를 accepts_nested_attributes_?

Question

나는 트랙이있다 has_many 퀴즈와 퀴즈 has_many 질문.

quiz.rb :

class Quiz < ActiveRecord::Base 
    belongs_to :track 
    has_many :questions, dependent: :destroy 
    accepts_nested_attributes_for :questions 
end 

question.rb :

class Question < ActiveRecord::Base 
    belongs_to :quiz 
end 

quizzes_controller.rb :에

def new 
    @quiz = Quiz.new 
    @track = Track.find(params[:permalink]) 
    @course = Course.find(@track.course_id) 

    3.times { @quiz.questions.build } 
end 

def create 
    @track = Track.find(params[:permalink]) 
    @quiz = @track.quizzes.build(quiz_params) 
    @course = Course.find(@track.course_id) 
    if @quiz.save 
    flash[:success] = 'Quiz successfully created' 
    redirect_to quiz_path @quiz 
    else 
    redirect_to track_path @track 
    end 
end 

private 

def quiz_params 
    params.require(:quiz).permit(:name, :information, :order, 
           :permalink, :user_id, 
           questions_attributes: [:id, :content]) 
end 

PARAMS 제출

{"utf8"=>"✓", 
"authenticity_token"=>"...", 
"quiz"=> { 
    "name"=>"Test Quiz", 
    "questions_attributes"=> { 
    "0"=>{"content"=>"This is question 1?"}, 
    "1"=>{"content"=>"This is question 2?"}, 
    "2"=>{"content"=>""} 
    }, "user_id"=>"1", 
    "order"=>"3" 
}, "commit"=>"Submit", 
"permalink"=>"1-basics"} 

제출을 누르면 퀴즈가 생성되지만 질문은 생성되지 않습니다.

새로운 PARAMS는 : content이 (요청 매개 변수를 고려) 비어있는 경우

가

reject_if: proc { |q| q['name'].blank? } 

당신은 아마 인스턴스를 거부한다 :

def quiz_params 
    params.require(:quiz).permit(:name, :information, :order, 
           :permalink, :user_id, 
           questions_attributes: [:id, :content, :_destroy, answers_attributes: [:id, :content, :_destroy]]) 
    end 

Answer 1

나는 문제가 accepts_nested_attributes_for에 생각

reject_if: proc { |q| q['content'].blank? } 

Answer 2

문제가 해결되었습니다. 중첩 된 매개 변수는 중괄호로 묶어야합니다.

def quiz_params 
    params.require(:quiz).permit(:name, :information, :order, 
           :permalink, :user_id, 
           { questions_attributes: [:id, :content] }) 
end
