Action View Context

Action View contexts are supplied to Action Controller to render template. The default Action View context is ActionView::Base.

In order to work with ActionController, a Context must implement:

Context#render_partial

- responsible for setting options[:_template]
- Returns String with the rendered partial
options<Hash>:: see _render_partial in ActionView::Base

Context#render_template[template, layout, options, partial]

- Returns String with the rendered template
template<ActionView::Template>:: The template to render
layout<ActionView::Template>:: The layout to render around the template
options<Hash>:: See _render_template_with_layout in ActionView::Base
partial<Boolean>:: Whether or not the template to render is a partial

An Action View context can also mix in Action View’s helpers. In order to mix in helpers, a context must implement:

Context#controller

• Returns an instance of AbstractController

In any case, a context must mix in ActionView::Context, which stores compiled template and provides the output buffer.
