Method: ActionView::Base#render

Defined in:
lib/action_view/base.rb

#render(options = {}, local_assigns = {}, &block) ⇒ Object

Returns the result of a render that’s dictated by the options hash. The primary options are:

  • :partial - See ActionView::Partials.

  • :update - Calls update_page with the block given.

  • :file - Renders an explicit template file (this used to be the old default), add :locals to pass in those.

  • :inline - Renders an inline template similar to how it’s done in the controller.

  • :text - Renders the text passed in out.

If no options hash is passed or :update specified, the default is to render a partial and use the second parameter as the locals hash.
