我在刪除和顯示用戶記錄時遇到問題。Ruby on Rails：路由錯誤
這裏是我的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
這裏是我的管理控制器：
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
這是我的觀點：
<%= 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>
我可以顯示用戶的數據庫，但當我去刪除一條記錄。我得到這個錯誤No route matches [DELETE] "https://stackoverflow.com/users/11"。我是新手，因此請在試圖幫助時記住這一點。提前致謝。
編輯：這裏是我的路線=>
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：這是我的routes.rb文件應該怎麼看過。使用耙路我可以改變路徑來解決我的問題。
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
我希望用戶能夠登錄，如果他們已被授予管理員身份，他們可以訪問網站的管理員部分，在那裏可以創建，編輯和刪除新用戶。我會給你一個建議。謝謝。 – Jazz
謝謝，現在完美。更新我的問題以顯示答案。 – Jazz
雖然可以嘗試命名空間某些動作/控制器，但我會建議在/ admin下使用一些用戶動作而不是名稱空間，而只是爲某些動作添加冗餘檢查，以確保只有那些用戶才能執行重要動作。隨着您的應用程序的增長，您將需要多種限制（由用戶狀態（管理員，讀者，其他？））。看看這個cancan，或者建立你自己的更簡單的角色系統。 –
