Ruby on Rails latest stable (v4.1.8) - 0 notes - Superclass: Rack::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).

Response is mostly a Ruby on Rails framework implementation detail, and should never be used directly in controllers. Controllers should use the methods defined in ActionController::Base instead. For example, if you want to set the HTTP response’s content MIME type, then use ActionControllerBase#headers instead of Response#headers.

Nevertheless, integration tests may want to inspect controller responses in more detail, and that’s when Response can be useful for application developers. Integration test methods such as ActionDispatch::Integration::Session#get and ActionDispatch::Integration::Session#post return objects of type TestResponse (which are of course also of type Response).

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

CONTENT_TYPE = "Content-Type".freeze

Attributes

[R] stream

The underlying body, as a streamable object.

[RW] charset

The charset of the response. HTML wants to know the encoding of the content you’re giving them, so we need to send that along.

[R] content_type

Sets the HTTP response’s content MIME type. For example, in the controller you could write this:

response.content_type = "text/plain"

If a character set has been defined for this response (see charset=) then the character set information will also be included in the content type information.

[RW] headers

Get and set headers for this response.

[RW] headers=

Get and set headers for this response.

[RW] header

Get and set headers for this response.

[W] sending_file
[R] status

The HTTP status code.

[RW] request

The request that the response is responding to.
