Ruby-on-rails 如何将自定义 RESTful 路由添加到 Rails 应用程序？

How to add a custom RESTful route to a Rails app?

提问by ma?ek

I'm reading these two pages

我正在阅读这两页

1. resources
2. Adding more RESTful actions

1. resources
2. Adding more RESTful actions

The Rails Guides page shows

Rails 指南页面显示

map.resources :photos, :new => { :upload => :post }

And its corresponding URL

以及它对应的网址

/photos/upload

This looks wonderful.

这看起来很棒。

My routes.rbshows this

我的routes.rb显示这个

map.resources :users, :new => { :signup => :get, :register => :post }

When I do: [~/my_app]$ rake routes

当我做： [~/my_app]$ rake routes

I see the two new routes added

我看到添加了两条新路线

  signup_new_user GET    /users/new/signup(.:format)
register_new_user POST   /users/new/register(.:format)

Notethe inclusion of /new! I don'twant that. I just want /users/signupand /users/register(as described in the Rails Routing Guide).

注意包含/new! 我不想要那个。我只是想要/users/signup和/users/register（如 Rails 路由指南中所述）。

Any help?

有什么帮助吗？

When you expose a controller as a resource, following actions are automatically added:

当您将控制器公开为资源时，会自动添加以下操作：

show
index
new
create
edit
update
destroy

These actions can be categorized in to two groups:

这些操作可以分为两组：

• :memberactions

• :member行动

The URL for the member action has the id of the target resource. E.g:

成员操作的 URL 具有目标资源的 id。例如：

users/1/edit 
users/1

You can think of :memberaction as an instance method on a class. It always applies on an existing resource.

您可以将:member操作视为类上的实例方法。它始终适用于现有资源。

Default member actions: show, edit, update, destroy

默认成员操作：show, edit, update,destroy

• :collectionactions

• :collection行动

The URL for the :collectionaction does not contain the id of the target resource. E.g:

操作的 URL:collection不包含目标资源的 id。例如：

users/login
users/register

You can think of :collectionaction as a static method on a class.

您可以将:collection操作视为类上的静态方法。

Default collection actions: index, new, create

默认收集操作：index, new,create

In your case you need two new actions for registration. These actions belong to :collection type( as you do not have the id of the user while submitting these actions). Your route can be as follows:

在您的情况下，您需要两个新的注册操作。这些操作属于 :collection 类型（因为您在提交这些操作时没有用户的 id）。您的路线可以如下：

map.resources :users, :collection => { :signup => :get, :register => :post }

The URL for the actions are as follows:

操作的 URL 如下：

users/signup
users/register

If you want to remove a standard action generated by Rails use :except/:only options:

如果要删除由 Rails 生成的标准操作，请使用 :except/:only 选项：

map.resources :foo, :only => :show

map.resources :foo, :except => [:destroy, :show]

I usually treat the confirmationaction as a :memberaction. In this case params[id]will contain the confirmation code.

我通常把这个confirmation动作当作一个:member动作。在这种情况下params[id]将包含确认代码。

Route configuration:

路由配置：

map.resources :users, :member => { :confirm => :get}

URL

网址

/users/xab3454a/confirm

confirm_user_path(:id => @user.confirmation_code) # returns the URL above

Controller

控制器

class UsersController < ApplicationController
  def confirm
    # assuming you have an attribute called `confirmation_code` in `users` table 
    # and you have added a uniq index on the column!!
    if User.find_by_confirmation_code(params[id])
      # success
    else
      # error
    end
  end
end

This can be taken as just another syntax -- something good to know may be.

这可以看作是另一种语法——一些值得了解的东西。

Syntax 1:

语法 1：

resources :users do
  member do
    get 'signup'
    post 'register'
  end
end

Rake Route Output will include

耙路线输出将包括

signup_users GET    /users/signup(.:format)    {:action=>"signup", :controller=>"users"}
register_users POST   /users/register(.:format)  {:action=>"register", :controller=>"use

rs"}

rs"}

Syntax 2:If you have only one collection route

语法 2：如果您只有一个收集路线

resources :users do
    get 'signup', :on => :collection
end

If i'm understanding your question right, you just want to rename the urls of the newand createactions.

如果我正确理解您的问题，您只想重命名new和create操作的网址。

This would be done like so:

这将像这样完成：

map.resources :users, :path_names => {:new => 'signup', :create => 'register'}

If you really would like to addnew routes with corresponding controller actions, then Damiens answer is the way to go.

如果您真的想添加具有相应控制器操作的新路由，那么 Damiens 的答案就是要走的路。

The newoption allows you to create new routes for creating new objects. That's why they're prefixed with that term.

该new选项允许您创建用于创建新对象的新路径。这就是为什么它们以该术语为前缀的原因。

What you're looking for is the :collectionoption.

您正在寻找的是:collection选项。

map.resources :users, :collection => { :signup => :get, :register => :post }

Which will create the /users/signupand /users/registerurls.

这将创建/users/signup和/users/registerurl。
