Ruby on rails "No route matches"
提问by Chris
I am new to Rails and am just implementing some basic applications. Just starting on my second app and have run into what is a basic problem, but Google is yielding me nothing.
我是 Rails 的新手，只是在实现一些基本的应用程序。刚刚开始我的第二个应用程序并遇到了一个基本问题，但谷歌没有给我带来任何好处。
Getting this error:
收到此错误：
No route matches {:controller=>"user", :action=>"admin_login"}
Here is my routes.rb
这是我的routes.rb
Blah::Application.routes.draw do
resources :items, :cart, :user
end
Here is my applications.html.erb(the idea is this is a header of course, and I'm trying to create a link to 'login'. Right now it's just supposed to set the 'login' session variable to '1'.
这是我的applications.html.erb（当然，这是一个标题，我正在尝试创建一个指向“登录”的链接。现在它只是应该将“登录”会话变量设置为“1”。
<!DOCTYPE html>
<html>
<head>
<title>Blah</title>
<%= stylesheet_link_tag :all %>
<%= javascript_include_tag :defaults %>
<%= csrf_meta_tag %>
</head>
<body>
<div id="headerHolder">
<div id="title">blah</div>
<div id="menu">
<div class ="menuItem">blog</div>
<div class ="menuItem">
<%= link_to "products", :controller => "items",
:action => "index" %>
</div>
<div class ="menuItem">contact</div>
<div class="menuItem">
<%= link_to "cart", :controller => "cart",
:action => "index" %>
</div>
<div class="menuItem">
<%= link_to_unless_current "admin", :controller => "user",
:action => "admin_login" %>
</div>
</div>
</div>
<div id="content">
<%= yield %>
</div>
</body>
</html>
And this is my user_controller.rb
这是我的 user_controller.rb
class UserController < ApplicationController
def index
end
def admin_login
session[:login] = 1
session[:cart] = nil
flash[:notice] = "Admin user successfully logged in, cart reset."
redirect_to :controller => :items
end
end
What am i missing in my routes.rb? Or otherwise...am sure it's something daft.
我缺少什么routes.rb？否则......我肯定这是愚蠢的事情。

You need to add admin_loginmethod to routes, like:-
您需要向admin_login路由添加方法，例如：-
map.connect '/user/admin_login', :controller => 'users', :action => 'admin_login'

For Rails > 3 you should use the new routing syntax:
对于 Rails > 3 你应该使用新的路由语法：
resources :items, :cart
resource :user do
# Route GET /user/admin_login
get 'admin_login', :on => :collection
end
See Rails guidesfor more information about routing.
有关路由的更多信息，请参阅Rails 指南。
