Action View Renderer

This is the main entry point for rendering. It basically delegates to other objects like TemplateRenderer and PartialRenderer which actually renders the template.

The Renderer will parse the options from the render or render_body method and render a partial or a template based on the options. The TemplateRenderer and PartialRenderer objects are wrappers which do all the setup and logic necessary to render a view and a new object is created each time render is called.

def render(context, options)
  render_to_object(context, options).body
end

render_body(context, options)

Render but returns a valid Rack body. If fibers are defined, we return a streaming body that renders the template piece by piece.

Note that partials are not supported to be rendered with streaming, so in such cases, we just wrap them in an array.

def render_body(context, options)
  if options.key?(:partial)
    [render_partial(context, options)]
  else
    StreamingTemplateRenderer.new(@lookup_context).render(context, options)
  end
