v7.1.3.4 - Show latest stable - 0 notes - Class: RenderingHelper

render(options = {}, locals = {}, &block) public

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

:partial - See ActionView::PartialRenderer.
: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.
:plain - Renders the text passed in out. Setting the content type as text/plain.
:html - Renders the HTML safe string passed in out, otherwise performs HTML escape on the string first. Setting the content type as text/html.
:body - Renders the text passed in, and inherits the content type of text/plain from ActionDispatch::Response object.

If no options hash is passed or if :update is specified, then:

If an object responding to render_in is passed, render_in is called on the object, passing in the current view context.

Otherwise, a partial is rendered using the second parameter as the locals hash.
