How to set default format for routing in Rails?

Question

There is the following code for routing:

  resources :orders, only: [:create], defaults: { format: \'json\' }
  resources :users,  only: [:create, :update],          


        

Answer 1

I'd rather add method to application_controller. And use it as before filter where I want.

class ApplicationController < ActionController::Base
...
private 
...
  def set_default_format
    params[:format] ||= "json"
  end
end

class UsersController < ApplicationController
  before_filter :set_default_format, only: [:create]
  ...
end

In this case default format wouldn't a surprise for new developers, because usually routes.rb is big and cumbersome
