What's the difference between render head :ok vs. render status :ok in Rails? They both get returned as the header right?
202
In Rails, the head method is shorthand for "respond only with this status, headers, and an empty body." The head method takes a symbol corresponding to a status, in this case :no_content for "204."
The head method can be used to send responses with only headers to the browser. The head method accepts a number or symbol (see reference table) representing an HTTP status code. head :ok sets render to return just the header with status 200. It's merely a shorthand for render nothing: true, status: :ok .
2.2. By default, if you use the :plain option, the text is rendered without using the current layout. If you want Rails to put the text into the current layout, you need to add the layout: true option and use the . text. erb extension for the layout file.
Rendering is the ultimate goal of your Ruby on Rails application. You render a view, usually . html. erb files, which contain a mix of HMTL & Ruby code.
There is no difference really. The Rails doc says this about head:
The head method can be used to send responses with only headers to the browser. The head method accepts a number or symbol (see reference table) representing an HTTP status code
head :ok sets render to return just the header with status 200.
It's merely a shorthand for render nothing: true, status: :ok.
Rails 5 will also do head :no_content by default when you don't have a template defined for an action
