method

render

v2.3.8 - Show latest stable - Class: ActionView::Base

render(options = {}, local_assigns = {}, &block)

public

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.
