How to request a response as JSON in Rails from a browser

I want to test the JSON response from a Rails controller GET action using only a browser.

If the url to the resource is http://localhost:3000/models/action, how do I tell rails to return the response as JSON?

You have to define in the controller the respond format:

def action 
   @objects = Model.all
   respond_to do |format|
      format.html
      format.json
   end
end

OR as a shorcut

def action 
   @objects = Model.all
   respond_to :html, :json
end

OR handle the format at controller level

class ModelsController < ApplicationController
   respond_to :html, :json

   def action
     @objects = Model.all
     respond_with(@objects)
  end
end

And now when you are calling http://localhost:3000/models/action.json the response will be JSON format

This is pretty simple once you figure out how to do it.

You can specify the type of the response by adding the type as an extension to the action.

For example, if we want the json response, could alter the request to be http://localhost:3000/models/action.json.
