중첩 된 자원 만 편집 새로운 것이 아니다 작업 나는 다음과 같은 자원을 정의 5.0.0.1

Question

레일 :

class Building < ApplicationRecord 
    has_many :building_regular_hours 

    def to_s 
    name 
    end 
end 

class BuildingsRegularHours < ApplicationRecord 
    belongs_to :building 
end 

내가 양식을 만들려고 오전 :

resources :buildings do 
    resources :buildings_regular_hours 
end 

내 모델

은 다음과입니다 BuildingRegularHours을 만들고 편집 할 수 있습니다. 현재 양식은 #edit에 표시되지만 #new에는 표시되지 않습니다.

new.html.erb :

<%= render 'form', buildings_regular_hour: @buildings_regular_hour, building: @building %> 

edit.html.erb :

<h1>Editing Buildings Regular Hour</h1> 

<%= render 'form', buildings_regular_hour: @buildings_regular_hour, building: @building %> 

<%= link_to 'Back', building_buildings_regular_hour_path(@building) %> 

_form.html.erb :

<%= form_for([building,buildings_regular_hour]) do |f| %> 
    <% if buildings_regular_hour.errors.any? %> 
    <div id="error_explanation"> 
     <h2><%= pluralize(buildings_regular_hour.errors.count, "error") %> prohibited this buildings_regular_hour from being saved:</h2> 

     <ul> 
     <% buildings_regular_hour.errors.full_messages.each do |message| %> 
     <li><%= message %></li> 
     <% end %> 
     </ul> 
    </div> 
    <% end %> 

    <div class="field">

    <div class="field">

콘솔을 통해 BuildingRegularHours을 추가 했으므로 #edit 작업을 시도했지만 제대로 작동하여 예상대로 양식을 표시합니다. @building 및 @building_regular_hour 모두가 컨트롤러에 의해 설정되어 있는지,

내가 제대로 form_for 태그에 자원을 중첩 한 점에 유의하고, 그 I : 나는 #new 조치를 시도 할 때, 나는 다음과 같은 오류가 발생합니다 #edit과 #new 모두 정확히 같은 방식으로 양식을 호출합니다. 이것은 이전에 중첩 된 리소스가 작동하도록하기 위해 수행해야했던 모든 작업이므로 다음에 수행해야 할 작업으로 손실이 조금 있습니다.

양식을 아직 만들지 않으 셨습니다. 거기서 할 일이 있다는 것을 알고 있습니다. 양식을 표시하기 위해 #new을 얻으려고합니다.

Answer 1

당신은 항상 BuildingsRegularHour 단수해야한다 협회에게

class Building < ApplicationRecord 
    has_many :buildings_regular_hours 

    def to_s 
    name 
    end 
end 

class BuildingsRegularHour < ApplicationRecord 
    belongs_to :building 
end
