Ruby on Rails Rails generate commands Rails Generate Controller
Example
we can create a new controller with rails g controller command.
$ bin/rails generate controller controller_name
The controller generator is expecting parameters in the form of generate controller ControllerName action1 action2.
The following creates a Greetings controller with an action of hello.
$ bin/rails generate controller Greetings hello
You will see the following output
create app/controllers/greetings_controller.rb
route get "greetings/hello"
invoke erb
create app/views/greetings
create app/views/greetings/hello.html.erb
invoke test_unit
create test/controllers/greetings_controller_test.rb
invoke helper
create app/helpers/greetings_helper.rb
invoke assets
invoke coffee
create app/assets/javascripts/greetings.coffee
invoke scss
create app/assets/stylesheets/greetings.scss
This generates the following
| File | Example |
|---|---|
| Controller File | greetings_controller.rb |
| View File | hello.html.erb |
| Functional Test File | greetings_controller_test.rb |
| View Helper | greetings_helper.rb |
| JavaScript File | greetings.coffee |
It will also add routes for each action in routes.rb
