Module: Turbo::Frames::FrameRequest

Extended by:
Defined in:


Turbo frame requests are requests made from within a turbo frame with the intention of replacing the content of just that frame, not the whole page. They are automatically tagged as such by the Turbo Frame JavaScript, which adds a Turbo-Frame header to the request. When that header is detected by the controller, we ensure that any template layout is skipped (since we're only working on an in-page frame, thus can skip the weight of the layout), and that the etag for the page is changed (such that a cache for a layout-less request isn't served on a normal request and vice versa).

This is merely a rendering optimization. Everything would still work just fine if we rendered everything including the layout. Turbo Frames knows how to fish out the relevant frame regardless.

This module is automatically included in ActionController::Base.
