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:
- 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.
