我在删除和显示用户记录时遇到问题。Ruby on Rails：路由错误
这里是我的routes.rb
FinalApp::Application.routes.draw do
resources :users
devise_for :users, :controllers => { :registrations => 'admin' }
resources :projects
match "search" => "projects#search", :as => :search
root :to => 'projects#index'
end
这里是我的管理控制器：
class AdminController < ApplicationController
def index
@users = User.all
respond_to do |format|
format.html # index.html.erb
format.json { render :json => @users }
end
end
def create
@user = User.new(params[:user])
respond_to do |format|
if @user.save
format.html { redirect_to @user, notice: 'User was successfully created.' }
format.json { render json: @user, status: :created, location: @user }
else
format.html { render action: "new" }
format.json { render json: @user.errors, status: :unprocessable_entity }
end
end
end
# GET /users/1
# GET /users/1.json
def show
@user = User.find(params[:id])
@user_user_id = params[:id]
respond_to do |format|
format.html # show.html.erb
format.json { render json: @user }
end
end
# GET /users/new
# GET /users/new.json
def new
@user = User.new
respond_to do |format|
format.html # new.html.erb
format.json { render json: @user }
end
end
# GET /users/1/edit
def edit
@user = User.find(params[:id])
end
# POST /users
# POST /users.json
# PUT /users/1
# PUT /users/1.json
def update
@user = User.find(params[:id])
respond_to do |format|
if @user.update_attributes(params[:user])
format.html { redirect_to @user, notice: 'User was successfully updated.' }
format.json { head :no_content }
else
format.html { render action: "edit" }
format.json { render json: @user.errors, status: :unprocessable_entity }
end
end
end
# DELETE /users/1
# DELETE /users/1.json
def destroy
@user = User.find(params[:id])
@user.destroy
respond_to do |format|
format.html { redirect_to users_url }
format.json { head :no_content }
end
end
end
这是我的观点：
<%= stylesheet_link_tag "admin" %>
<body>
<div id ="title1">Admin</div>
<div class ="menu"></div>
<div id ="section3">
<table id = "mytable">
<table border = "1">
<tr>
<th>Username </th>
<th>Email</th>
<th>First Name</th>
<th>Last Name</th>
<th>Admin?</th>
<th></th>
<th></th>
<th></th>
</tr>
<%= link_to "New User", admin_new_path %><br />
<% @users.each do |t| %>
<tr>
<td><%= t.username %></td>
<td><%= t.email %></td>
<td><%= t.firstname %></td>
<td><%= t.lastname %></td>
<td><%= t.admin %></td>
<td><%= link_to 'Show', t %></td>
<td> <%= button_to "Delete", t, method: :delete, data: { confirm: 'Are you sure?' } %></td>
</tr>
<% end %>
</table></br>
</body>
</html>
我可以显示用户的数据库，但当我去删除一条记录。我得到这个错误No route matches [DELETE] "https://stackoverflow.com/users/11"。我是新手，因此请在试图帮助时记住这一点。提前致谢。
编辑：这里是我的路线=>
admin_index GET /admin(.:format) admin#index
POST /admin(.:format) admin#create
new_admin GET /admin/new(.:format) admin#new
edit_admin GET /admin/:id/edit(.:format) admin#edit
admin GET /admin/:id(.:format) admin#show
PUT /admin/:id(.:format) admin#update
DELETE /admin/:id(.:format) admin#destroy
new_user_session GET /users/sign_in(.:format) devise/sessions#new
user_session POST /users/sign_in(.:format) devise/sessions#create
destroy_user_session DELETE /users/sign_out(.:format) devise/sessions#destroy
user_password POST /users/password(.:format) devise/passwords#create
new_user_password GET /users/password/new(.:format) devise/passwords#new
edit_user_password GET /users/password/edit(.:format) devise/passwords#edit
PUT /users/password(.:format) devise/passwords#update
cancel_user_registration GET /users/cancel(.:format) admin#cancel
user_registration POST /users(.:format) admin#create
new_user_registration GET /users/sign_up(.:format) admin#new
edit_user_registration GET /users/edit(.:format) admin#edit
PUT /users(.:format) admin#update
DELETE /users(.:format) admin#destroy
projects GET /projects(.:format) projects#index
POST /projects(.:format) projects#create
new_project GET /projects/new(.:format) projects#new
edit_project GET /projects/:id/edit(.:format) projects#edit
project GET /projects/:id(.:format) projects#show
PUT /projects/:id(.:format) projects#update
DELETE /projects/:id(.:format) projects#destroy
search /search(.:format) projects#search
root / projects#index
EDIT2：这是我的routes.rb文件应该怎么看过。使用耙路我可以改变路径来解决我的问题。
FinalApp::Application.routes.draw do
# website home
root :to => 'projects#index'
# devise sessions (NB does not use admin/users controller)
devise_for :users, :controllers => { :registrations => 'users' }
# normal controllers
resources :users
resources :projects
# custom routes
match "search" => "projects#search", :as => :search
end
我希望用户能够登录，如果他们已被授予管理员身份，他们可以访问网站的管理员部分，在那里可以创建，编辑和删除新用户。我会给你一个建议。谢谢。 – Jazz
谢谢，现在完美。更新我的问题以显示答案。 – Jazz
虽然可以尝试命名空间某些动作/控制器，但我会建议在/ admin下使用一些用户动作而不是名称空间，而只是为某些动作添加冗余检查，以确保只有那些用户才能执行重要动作。随着您的应用程序的增长，您将需要多种限制（由用户状态（管理员，读者，其他？））。看看这个cancan，或者建立你自己的更简单的角色系统。 –
