Action Dispatch Response

Represents an HTTP response generated by a controller action. Use it to retrieve the current state of the response, or customize the response. It can either represent a real HTTP response (i.e. one that is meant to be sent back to the web browser) or a TestResponse (i.e. one that is generated from integration tests).

The Response object for the current request is exposed on controllers as ActionController::Metal#response. ActionController::Metal also provides a few additional methods that delegate to attributes of the Response such as ActionController::Metal#headers.

Integration tests will likely also want to inspect responses in more detail. Methods such as Integration::RequestHelpers#get and Integration::RequestHelpers#post return instances of TestResponse (which inherits from Response) for this purpose.

For example, the following demo integration test prints the body of the controller response to the console:

class DemoControllerTest < ActionDispatch::IntegrationTest
  def test_print_root_path_to_console
    get('/')
    puts response.body
  end
end
