rails-generate: Generate a new controller named Posts with actions index, show, new and create.

rails

$ rails generate controller ${Posts} ${index} ${show} ${new} ${create}

try on your machine

The command "rails generate controller" is used to generate a new controller file in a Ruby on Rails application.

In this specific command, the parameters are as follows:

${Posts}: This is the name of the controller that will be generated. It is common practice in Rails to use the singular form of the resource for the name of the controller. For example, if working with a "Post" resource, the controller name would typically be "PostsController".
${index}: This is the name of the action method that will be generated in the controller. The "index" action is responsible for displaying a list of all posts.
${show}: This is the name of another action method that will be generated in the controller. The "show" action is responsible for displaying the details of a single post.
${new}: This is the name of an additional action method that will be generated in the controller. The "new" action is responsible for displaying a form to create a new post.
${create}: This is the name of yet another action method that will be generated in the controller. The "create" action is responsible for actually creating a new post based on the submitted form data.

So, running this command will generate a new controller file named "PostsController" with the actions "index", "show", "new", and "create" implemented in it.
