NoMethodError (undefined method `respond_to\' for #
Did         


        

Answer 1

ActionController::API does not include the ActionController::MimeResponds module. If you want to use respond_to you need to include MimeResponds.

class ApplicationController < ActionController::API
  include ActionController::MimeResponds
end


class Api::MyController < ApplicationController
  def method1
    # ...
    respond_to do |format|
      format.xml { render(xml: "fdsfds") }
      format.json { render(json: "fdsfdsfd" ) }
    end
  end
end
