Module: ViewComponent::CaptureCompatibility

Defined in:
lib/view_component/capture_compatibility.rb

Overview

CaptureCompatibility is a module that patches #capture to fix issues related to ViewComponent and functionality that relies on ‘capture` like forms, capture itself, turbo frames, etc.

This underlying incompatibility with ViewComponent and capture is that several features like forms keep a reference to the primary ‘ActionView::Base` instance which has its own @output_buffer. When `#capture` is called on the original `ActionView::Base` instance while evaluating a block from a ViewComponent the @output_buffer is overridden in the ActionView::Base instance, and not the component. This results in a double render due to `#capture` implementation details.

To resolve the issue, we override ‘#capture` so that we can delegate the `capture` logic to the ViewComponent that created the block.
