HTTP Verbs
Every web request (such as going to products/3) has an HTTP verb (or "method") associated with it, which explains the action the user wants to perform. The most common verb is GET, to get a web page or file without changing anything. As you can see above, there are other HTTP verbs; here's what each request is for:
- POST - create a resource, such as a new user or product
- GET - display a resource on a site, such as a product information
- PUT - update a resource (we don't need that yet)
- DELETE - delete a resource, such as a user or product
As mentioned in Standard Resources, Rails provides a standard way to map URLs to actions. These 4 HTTP actions correspond to the 4 standard CRUD operations - Create, Read, Update, Delete. Rails helps you create standardized routes where each requests uses the appropriate verb. When your routes follow this standardized format, they are called RESTful resources.
