- You can search through routes using the -g option. This shows any route that partially matches the helper method name, the URL path or the HTTP verb:
$ rake routes -g new_user # Matches helper method
$ rake routes -g POST # Matches HTTP Verb POSTClicking "Copy Code" button will copy the code into the clipboard - memory. Please paste(Ctrl+V) it in your destination. The code will get pasted.

$ rake routes -g POST # Matches HTTP Verb POST
# OR
$ rails routes -g new_user # Matches helper method
$ rails routes -g POST # Matches HTTP Verb POST Clicking "Copy Code" button will copy the code into the clipboard - memory. Please paste(Ctrl+V) it in your destination. The code will get pasted.

- when running rails server in development mode, you can access a web page that shows all your routes with a search filter, matched in priority from top to bottom, at
/rails/info/routes. It will look like this:
| Helper | HTTP Verb | Path | cONTROLLER#Action |
|---|---|---|---|
| Path / Url | [ Path Match ] | ||
| users_path | GET | /users(.:format) | users#index |
| POST | /users(.:format) | users#create | |
| new_user_path | GET | /users/new(.:format) | users#new |
| edit_user_path | GET | /users/:id/edit(.:format) | users#edit |
| user_path | GET | /users/:id(.:format) | users#show |
| PATCH | /users/:id(.:format) | users#update | |
| PUT | /users/:id(.:format) | users#update | |
| DELETE | /users/:id(.:format) | users#destroy |
- Routes can be declared available for only members (not collections) using the method resource instead of resources in routes.rb. With resource, an index route is not created by default, but only when explicitly asking for one like this:
resource :orders, only: [:index, :create, :show]
