class ActionView::Renderer - actionview-4.2.4 Documentation

# 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.

### Public Class Methods

      @lookup_context = lookup_context
    end

### Public Instance Methods

render(context, options) click to toggle source

Main render entry point shared by AV and AC.

    # File lib/action_view/renderer/renderer.rb, line 19
    def render(context, options)
      if options.key?(:partial)
        render_partial(context, options)
      else
        render_template(context, options)
      end
    end

render_body(context, options) click to toggle source

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 32
    def render_body(context, options)
      if options.key?(:partial)
        [render_partial(context, options)]
      else
        StreamingTemplateRenderer.new(@lookup_context).render(context, options)
      end
    end
