In 4 cases


# Example resource route within a namespace:
namespace :admin do
  # Directs /admin/test/* to Admin::ProductsController
  # (app/controllers/admin/test_controller.rb)
  resources :test
Watch carefully

# Directs /admin/test/* to Admin::TestController
# (app/controllers/admin/test_controller.rb)
Create a directory admin on controllers, a new test_controller.rb in admin. Test_controller.rb specific code to see:

# What the controller on Admin::

class Admin::TestController <ApplicationController



The table below details. The resources table with the same, but the front with a admin

HTTP Verb Path action
GET /admin/test index
GET /admin/test/new new
POST /admin/test create
GET /admin/test/:id show
GET /admin/test/:id/edit edit
PATCH/PUT /admin/test/:id update
DELETE /admin/test/:id destroy
PATCH/PUT, DELETE in the general said, can refer to.

If you want to route /test (not /admin prefix) matched to Admin:: TestController, you need it:

scope :module => "admin" do
  resources :test, :comments

Or when matching on a single Resource

resources :test, :module => "admin"

The URL into

http://ip:host/Test can also access to TestController Action

But if you want to: /admin/test routing to match to TestController (no Admin:: controller this module as a prefix), you can use

scope "/admin" do
  resources :test
Or when the matching for a single Resource wrote

resources :test, :path => "/admin/test"

In 5 cases

Resources nested together, individuals will not be used in the actual development, this first pass.

resources :publishers do
  resources :magazines do
    resources :photos
The above several commonly used, is also common, first to some. Below is a list of a few magic usage.

This route will match like /photos/A12345 routing. You can use this more concise way to write the rules:

match 'photos/:id' => 'photos#show', :id => /[A-Z]\d{5}/

match "/stories" => redirect("/posts")
You can also put the dynamic part of the error handling in a match command (rescue) to redirect

match "/stories/:name" => redirect("/posts/%{name}")
:The controller option allows you to select the associated with the resource controller. For example:

resources :photos, :controller => "images"
You can use the constraints option to define: ID format. For example:

resources :photos, :constraints => {:id => /[A-Z][A-Z][0-9]+/}
This statement limits: ID must match the regularization parameter. So, in this example, the route will no longer match /photos/1, and only /photos/RR27 that will be matched. You can use a code block to a single canonical restrictions applied to multiple rules.
constraints(:id => /[A-Z][A-Z][0-9]+/) do
  resources :photos
  resources :accounts

The above according to some online resources and their own understanding, summary. There are parts of the interior is the original copy. Thanks contributors´╝ü
