Module: LocoMotion::Patches::ViewComponent::SlotPatch

Defined in:
lib/loco_motion/patches/view_component/slot_loco_parent_patch.rb

Overview

Monkey patches ViewComponent::Slot so the LocoMotion component it wraps can reach its parent — ViewComponent::Slot has no built-in way to do that on its own. Slot-based components (tabs, accordion, drawer, and others) depend on this patch to inherit config and state from their parent via loco_parent.

def __vc_component_instance=(instance)
  # Call the original implementation
  super

  # And set the Loco parent
  set_loco_parent
end

#set_loco_parent(parent = @parent) ⇒ Object

Guard-clause logic the overrides above rely on: sets the parent on the wrapped instance, skipping when the parent is missing, no instance is set yet, or the instance already has a loco parent.

def set_loco_parent(parent = @parent)
  return if parent.nil?
  return if @__vc_component_instance.nil?
  return if @__vc_component_instance.loco_parent.present?

  @__vc_component_instance.set_loco_parent(parent)
end

#to_s ⇒ Object

Set the loco parent again right before the slot renders.
