ruby - 울타리 - 데이터베이스에 숨겨진 필드 태그 저장

초보자 레일 질문 :

와이즈 비즈가있다 내 양식의 맨 위에 구독을 쉽게 만들 수 있도록 params 값을 데이터베이스에 저장하고 싶습니다. 아래에 내보기, 컨트롤러 및 모델 파일이 있습니다. 가장 좋은 방법은 무엇입니까? info .. 여기에서 배우고 감사의 말이 필요하면 알려주십시오!

컨트롤러 :

      <%= hidden_field_tag :plan, params[:plan] %>
      <div class="form-group">

모델 :

class SchoolRegistrationsController < ApplicationController
  def new
    @register = SchoolRegistration.new
  end
  def create
    @register = SchoolRegistration.new(register_params)
      if @register.save_with_subscription
      flash[:success] = "Congratulations!  You registered your school!"
      redirect_to new_user_registration_path
      else
      flash[:danger] = @register.errors.full_messages.join(", ")
      redirect_to new_registration_path
      end
  end
  private
    def register_params
      params.require(:school_registration).permit(:name_of_person_completing_form, :email, :role_in_school, :school_name, :grade_levels, :street_name, :city, :state, :zip_code)
    end

        save!
      # This runs save on the spot and sends it to the database

답변 # 1
hidden_field_tag 대신 hidden_field를 사용해야합니다 .
hidden_tag 사용 당신은 plan 를 잡을 수 있습니다 와이즈 비즈 .

이것은 당신이 원하는 것을 할 것입니다 :
```
params[:school_registration]
```
와 <%= f.hidden_field :plan, value: params[:plan] %> 를 허용하는 것을 잊지 마세요

업데이트

plan 로 갈 수 있습니다 또한이 경우 필드 이름을 수동으로 지정해야합니다.
```
hidden_field_tag
```
답변 # 2
다음을 시도하십시오
```
hidden_field_tag 'school_registration[plan]', params[:plan]
```
<%= f.hidden_field :plan, value: params[:id] %> 업데이트 register_params 의 방법 섹션
```
private
```
params.require(:school_registration).permit(:name_of_person_completing_form, :email, :role_in_school, :school_name, :grade_levels, :street_name, :city, :state, :zip_code, :plan) 추가

도움이 필요합니다
답변 # 3
plan_id를 허용 된 매개 변수에 포함 시키려고합니다 :
```
plan
```
숨겨진 매개 변수를 양식의 일부로 추가합니다 :
```
def register_params
  params.require(:school_registration).permit(:name_of_person_completing_form, :email, :role_in_school, :school_name, :grade_levels, :street_name, :city, :state, :zip_code, :plan_id)
end
```
컨트롤러에서 값을 설정합니다 :
```
<%= form_for @register, html: {id: 'payment-form'} do |f| %>
  <%= f.hidden_field :plan_id %>
```
def new # You should also validate if the plan exists in advance @register = SchoolRegistration.new(plan_id: params[plan]) end
