What is resource?
A resource is the term used for a collection of similar objects, such as organization, people or books. You can create, read, update and destroy items for a resource and these operations are referred to as CRUD operations.
Rails provides a resources method which can be used to declare a standard REST resource. For example, you can add a posts resource to the config/routes.rb for your blog.
Rails.application.routes.draw do
get 'welcome/index'
resources :posts
root 'welcome#index'
end
And then run:
administrator@ubuntu:~/blog$ rails routes
Prefix Verb URI Pattern Controller#Action
welcome_index GET /welcome/index(.:format) welcome#index
posts GET /posts(.:format) posts#index
POST /posts(.:format) posts#create
new_post GET /posts/new(.:format) posts#new
edit_post GET /posts/:id/edit(.:format) posts#edit
post GET /posts/:id(.:format) posts#show
PATCH /posts/:id(.:format) posts#update
PUT /posts/:id(.:format) posts#update
DELETE /posts/:id(.:format) posts#destroy
root GET / welcome#index
This shows that you have a complete CRUD actions implicitly ready inside the routing table.
