Method: ActionController::Rendering#render_to_string

Defined in:
lib/action_controller/metal/rendering.rb

#render_to_string ⇒ Object

Similar to #render, but only returns the rendered template as a string, instead of setting ‘self.response_body`. – Override render_to_string because body can now be set to a Rack body.
