class ActionView::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.

Main render entry point shared by Action View and Action Controller.
# File lib/action_view/renderer/renderer.rb, line 21 def render(context, options) render_to_object(context, options).body end
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.
# File lib/action_view/renderer/renderer.rb, line 38 def render_body(context, options) if options.key?(:partial) [render_partial(context, options)] else StreamingTemplateRenderer.new(@lookup_context).render(context, options) end end
