[RUBY] Specify home view in rails app [root]

About root

You may want to specify the main screen in the rails app. In such a case, you can easily specify it by specifying root in routes.rb.


root to: "Controller name#Action name"

Now you can specify the main screen.

Let's write an example. If you want to specify the view of the index action of posts_controller on the main screen,


root to: "posts#index"

It is described as.

In this case, even if you do not write the index action in posts_controller, you can display it as a view as long as you have app / views / posts / index.html.erb.

Thank you for watching until the end.
