メソッドのhas_manyスローでは、Rspec削除オブジェクトの失敗は、一致しないルート{：アクション=> "破棄"

Question

私の目標はhas_manyスローメソッドで作成された関係を削除することです。私はこれに続いたMHartl's tutorial。

relationships_controller.rb：

class RelationshipsController < InheritedResources::Base 

     def create 
     user = User.find(params[:followed_id]) 
     current_user.follow(user) 
     redirect_to user 
     end 

     def destroy 
     user = Relationship.find(params[:id]).followed 
     current_user.unfollow(user) 
     redirect_to user 
     end 
    end 

relationships_controller_spec.rb：

require 'rails_helper' 

describe RelationshipsController do 
    let(:relationship) { create(:relationship) } 
    let(:user) { create(:user) } 

    before do 
    sign_in :user, create(:user) 
    end 

    describe '#create' do 
    let!(:followed) { create(:user) } 
    it "should require logged-in user to create relationship" do 
     expect{ 
     post :create, followed_id: followed.id 
     }.to change(Relationship, :count).by(1) 
     redirect_to root_path 
    end 
    end 

    describe '#destroy' do 
    let!(:relationship) { create(:relationship) } 

    it "should require logged-in user to destroy relationship" do 
     expect { 
     delete :destroy, id: relationship.id 
     }.to change(Relationship, :count).by(-1) 
     redirect_to root_path 
    end 
    end 
end 

routes.rbを：

Rails.application.routes.draw do 
    devise_for :users, controllers: { sessions: "users/sessions" } 
    devise_for :admin_users, ActiveAdmin::Devise.config 

    ActiveAdmin.routes(self) 

    mount Peek::Railtie => '/peek' 

    resources :users do 
    member do 
     get :following, :followers 
    end 
    end 
    resources :relationships, only: [:create, :destroy] 

    root to: "records#index" 
end 

user.rb：

class User < ActiveRecord::Base 
    devise :database_authenticatable, :registerable, 
     :recoverable, :rememberable, :trackable, 
     :validatable, :confirmable, :timeoutable 

    # Associations 
    has_many :active_relationships, class_name: "Relationship", 
            foreign_key: "follower_id", 
            dependent: :destroy 
    has_many :passive_relationships, class_name: "Relationship", 
            foreign_key: "followed_id", 
            dependent: :destroy 
    has_many :following, through: :active_relationships, source: :followed 
    has_many :followers, through: :passive_relationships, source: :follower 

    # Follows a user. 
    def follow(other_user) 
    active_relationships.create(followed_id: other_user.id) 
    end 

    # Unfollows a user. 
    def unfollow(other_user) 
    active_relationships.find_by(followed_id: other_user.id).destroy 
    end 

    # Returns true if the current user is following the other user. 
    def following?(other_user) 
    following.include?(other_user) 
    end 
end 

工場：

FactoryGirl.define do 
    factory :relationship do 
    follower_id 1 
    followed_id 1 
    end 
end 

障害：

1) Relationships GET /relationships works! (now write some real specs) 
    Failure/Error: get relationships_path 

    ActionController::RoutingError: 
     No route matches [GET] "/relationships" 

    2) RelationshipsController#destroy should require logged-in user to destroy relationship 
    Failure/Error: active_relationships.find_by(followed_id: other_user.id).destroy 

    NoMethodError: 
     undefined method `id' for nil:NilClass 

Answer 1

破壊するためにあなたのルートは/relationships/:idで、コントローラは、関係を破壊するが、代わりに関係の:idを渡すあなたが:followed_idを渡しているので、実際にはそのようなはありませんルート。

つまり、あなたのルートやコントローラを変更するか、または、現在のコードの作業の変更を行うために：

delete :destroy, id: relationship.id
