当我将提要部分包含在我的主页中时，代码可以正常工作。但是，当我将删除链接添加到提要项时，我不断收到“未定义方法 'todo_path'”错误。有谁能够帮我？
这是我的 Rspec 失败：
1) Todo pages todo destruction as correct user should delete a todo
Failure/Error: before { visit root_path }
ActionView::Template::Error:
undefined method `todo_path' for #<#<Class:0x00000004eac910>:0x00000004eb2b08>
这是我在本地主机上的错误：
8: Posted <%= time_ago_in_words(feed_item.created_at) %> ago.
9: </span>
10: <% if current_user?(feed_item.user) %>
11: <%= link_to "delete", feed_item, method: :delete, data: { confirm: 'Are you sure?' } %>
12: <% end %>
13: </li>
这是我的 _feed_item.html.erb：
<li id="<%= feed_item.id %>">
<%= link_to gravatar_for(feed_item.user), feed_item.user %>
<span class="user">
<%= link_to feed_item.user.username, feed_item.user %>
</span>
<span class="entry"><%= feed_item.entry %></span>
<span class="timestamp">
Posted <%= time_ago_in_words(feed_item.created_at) %> ago.
</span>
<% if current_user?(feed_item.user) %>
<%= link_to "delete", feed_item, method: :delete, data: { confirm: 'Are you sure?' } %>
<% end %>
</li>
这是我的 TodosController.rb：
class TodosController < ApplicationController
before_filter :signed_in_user, only: [:create, :destroy]
before_filter :correct_user, only: :destroy
# GET /todos
# GET /todos.json
def index
#@user = User.find(params[:user_id])
@user = User.find_by_id(params[:user_id])
@todo = @user.todos
respond_to do |format|
format.html # index.html.erb
format.json { render json: @todos }
end
end
# GET /todos/1
# GET /todos/1.json
def show
@todo = Todo.find(params[:id])
@todo.user = User.find_by_id(params[:user_id])
@user = @todo.user
respond_to do |format|
format.html # show.html.erb
format.json { render json: @todo }
end
end
# GET /todos/new
# GET /todos/new.json
def new
@user = current_user
@todo = Todo.new
respond_to do |format|
format.html # new.html.erb
format.json { render json: @todo }
end
end
# GET /todos/1/edit
def edit
@todo = Todo.find(params[:id])
@todo.user = User.find_by_id(params[:user_id])
@user = @todo.user
end
# POST /todos
# POST /todos.json
def create
@todo = current_user.todos.build(params[:todo])
#@todo.user = User.find_by_id(params[:user_id])
@todo.user = current_user
@user = @todo.user
respond_to do |format|
if @todo.save
#format.html { redirect_to user_todo_path(@user, @todo), notice: 'Todo was successfully created.' }
format.html { redirect_to user_todo_path(@user, @todo), notice: 'Todo was successfully created!' }
format.json { render json: @user, status: :created, location: @user }
else
@feed_items = []
format.html { render action: "new" }
format.json { render json: @todo.errors, status: :unprocessable_entity }
end
end
end
# PUT /todos/1
# PUT /todos/1.json
def update
@todo = Todo.find(params[:id])
respond_to do |format|
if @todo.update_attributes(params[:todo])
format.html { redirect_to @todo, notice: 'Todo was successfully updated.' }
format.json { head :no_content }
else
format.html { render action: "edit" }
format.json { render json: @todo.errors, status: :unprocessable_entity }
end
end
end
# DELETE /todos/1
# DELETE /todos/1.json
def destroy
@todo.destroy
respond_to do |format|
format.html { redirect_to root_url }
format.json { head :no_content }
end
end
private
def correct_user
@todo = current_user.todos.find_by_id(params[:id])
redirect_to root_url if @todo.nil?
end
end
编辑：这是我的规范文件（todo_pages_spec.rb）：
require 'spec_helper'
describe "Todo pages" do
subject { page }
let(:user) { FactoryGirl.create(:user) }
before { sign_in user }
describe "todo creation" do
before { visit new_user_todo_path(user) }
describe "with invalid information" do
it "should not create a todo" do
expect { click_button 'Submit' }.not_to change(Todo, :count)
end
describe "error messages" do
before { click_button 'Submit' }
it { should have_content('error') }
end
end
describe "with valid information" do
before{ fill_in 'Entry', with: "Lorem ipsum" }
it "should create a todo" do
expect { click_button 'Submit' }.to change(Todo, :count).by(1)
end
end
end
describe "todo destruction" do
before { FactoryGirl.create(:todo, user: user) }
describe "as correct user" do
before { visit root_path }
it "should delete a todo" do
expect { click_link "delete" }.to change(Todo, :count).by(-1)
end
end
end
end
这是我的 routes.rb：
home_index GET /home/index(.:format) home#index
user_todos GET /users/:user_id/todos(.:format) todos#index
POST /users/:user_id/todos(.:format) todos#create
new_user_todo GET /users/:user_id/todos/new(.:format) todos#new
edit_user_todo GET /users/:user_id/todos/:id/edit(.:format) todos#edit
user_todo GET /users/:user_id/todos/:id(.:format) todos#show
PUT /users/:user_id/todos/:id(.:format) todos#update
DELETE /users/:user_id/todos/:id(.:format) todos#destroy
users GET /users(.:format) users#index
POST /users(.:format) users#create
new_user GET /users/new(.:format) users#new
edit_user GET /users/:id/edit(.:format) users#edit

PUT /users/:id(.:format) users#update
DELETE /users/:id(.:format) users#destroy
sessions POST /sessions(.:format) sessions#create
