在路线中渲染RESTful路线

Question

I'm not exactly sure if I have a clear understanding what rendering means in RESTful routes.

For example: In my Pages controller,

class PagesController < ApplicationController
  def home
    render "home.html.erb"
  end
end

on my routes.rb file i have the following:

get "/" => "pages#home"

does render home.html.erb mean output the info on this page?

Thanks!

Yes. render does the work of rendering your application's content for use by a browser when your action is invoked. You don't really need to explicitly specify the name of the view if your view name matches the action name and placed in the right folder in app/views

for eg, if you have your view in app/views/pages/ , your controller can just be

class PagesController < ApplicationController
  def home
  end
end

And even if you want to render a template which name is different than the action name (or localized in another place); you don't need to specify the file extension, only its name (path/name if outside the scope of the designated folder for the views of your controller)...

Ex, if you have a template app/views/pages/home_template.html.erb for your home action you could do

class PagesController < ApplicationController
  def home
    render 'home_template' 
  end
end
