Application_Controller.rb render method

Question

class ApplicationController < ActionController::Base
    def hello
        render html: 'Hello World!'
    end
end

I have this defined in my application_controller.rb file and I'm just trying to figure out what the "html: 'Hello World!'" syntax is. Is this like a hash passed to the render method?

It is the same as `render({html: 'Hello World'})` if that helps — Eyeslandic, Mar 02 '21 at 20:04

It’s html that gets shown to the user when they go to that specific route. For your instance it might be something like /hello. To answer your question yes it’s a hash and you can render other options such as JSON and XML.

You can check out the api docs for all the different options and syntax https://apidock.com/rails/ActionController/Base/render
