未定義のメソッド `user_revisers_path '" NoMethodError in Revisers＃new "

Question

私はこの奇妙なエラーが発生しました。これは私のアプリのroutes.rb部分から来ていると仮定しています。私はユーザーがフォームに入るときに改訂者になる機会を与えようとしています。ユーザーは一度だけ改訂者になることができるので、そのhas_one reviserのuser.rbモデルありがとう！

routes.rbを：

Rails.application.routes.draw do 
    root 'pages#home' 

    devise_for :users , 
      :path => '' , 
      :path_names => { :sign_in => 'login', :sign_out => 'logout', :edit => 'profile' }, 
      :controllers => { :omniauth_callbacks => 'omniauth_callbacks', 
           :registrations => 'registrations' 
          } 

    resources :users, only: [:index, :show] do 
    resource :reviser 
    end 

revisers_controller：

class RevisersController < ApplicationController 
    before_action :set_reviser, only: [:show, :edit, :update] 
    before_action :authenticate_user!, except: [:show] 

    def index 
    @reviser = current_user.reviser 
    end 

    def show 
    end 

    def new 
    @reviser = current_user.build_reviser(params[:reviser]) 
    @user = User.find(params[:user_id]) 
    end 

    def create 
    @reviser = current_user.reviser.build(reviser_params) 

    if @reviser.save 
     redirect_to @reviser,notice: "saved...." 
    else 
     render :new 
    end 
    end 

    def edit 
    set_reviser 
    end 

    def update 
    set_reviser 

    if @reviser.update(reviser_params) 
     redirect_to @reviser, notice: "updated.." 
    else 
     render :edit 
    end 
    end 

    private 
    def set_reviser 
    @reviser = Reviser.find(params[:id]) 
    end 

    def reviser_params 
    params.require(:reviser).permit(:description, :average_start, :average_end, :max_pages, :price_per, :active) 
    end 
end 

new.html

<%= form_for [current_user, @reviser] do |f| %> 
    <div class="row"> 
    <div class="div.col-md-4 select"> 
     <div class="form-group"> 
     <label>dsd</label> 
     <%= f.input :description, label: false, class: 'controls',:input_html => { :id => 'description' } %> 
     </div> 
    </div> 
    </div> 

    <%= f.submit "Become Adviser", class: "btn btn-large btn-primary" %> 
<% end %>

Answer 1

あなたは:reviserルートの特異リソース定義を持っています。これはあなたがしようとしていることには意味がありますが、form_for [current_user, @reviser]によって生成されたルートは:user_idと:idの両方を持つルートを生成しようとします。

resource :reviserは:idを作成しないため、:idフィールドはあなたのケースでは定義されていません。

ソリューションは、明示的にルートあなたたいあなたform_forにURLを設定することです：あなたのコードとの大きな問題は、あなたのことです

form_for @reviser, url: edit_user_reviser_path(user_id: current_user.id) 

：それはの線に沿って何かする必要があります

あなたのコントローラのidによって改訂者を直接参照しています。現在のルート設定では、Reviser.find()メソッドでエラーが返されます。しかし、もっと重要なのは、悪意のあるユーザーがPATCH要求にidパラメータを送信して、別のユーザーに属するレコードを乗っ取りして更新する可能性があるためです。

単純な解決策は、リビジョンオブジェクトをcurrent_userで直接参照することです。

def set_reviser 
    @reviser = current_user.reviser 
end
