여러 양식을 레일에 제출하십시오.

Question

현재 사용자가 하나의 제출 버튼으로 동일한 개체의 여러 양식을 제출할 수있는 새로운 기능을 추가하고 있습니다.

나는 'add_inquery'버튼을 추가했는데, 사용자가 클릭 할 때 새로운 양식이 (같은 페이지에서) 렌더링된다. 사용자가 제출할 양식 수를 제한하지 않습니다. 일반적으로 원할 경우 10 개에서 20 개의 양식으로 제출할 수 있습니다.

내가 오류는 다음과 같습니다

Answer 1

당신은 form_tag 정의 된 형태의 내부 f.fields_for을 요구하고있다. f.fields_for을 사용하려면 form_for을 사용하여 정의 된 모델이 있어야합니다. 당신이 form_for를 사용하지 않고 fields_for를 사용하려면

, 처음에 f.을 제거하려고 그냥 사용 :이 자습서를 따라하고

fields_for '' do |fd| 

Answer 2

fields_for는 특정 모델 객체의 범위를 만들고 form_for 도우미에 대해 사용할 수 있습니다.

난 당신이 form_tag을 사용하고 있고이 때 form_tag에 대한 fields_for 방법을 기대하고 있다고 보았다. 따라서 오류가 발생합니다. fields_for

업데이트에 대한 더 많은 정보를 원하시면 확인하시기 바랍니다 : 아래로

는 fields_for를 사용합니다. 컨트롤러에서 new 작업으로 시작된 pricing_histories 개체를 반복해야합니다.

    - @pricing_histories.each do |pricing_history| 
    = fields_for 'pricing_history[]', pricing_history do |p| 
     = render 'form_body', f: pricing_history, object: @pricing_history
