调研方向

Read the Data Inheritance page and the linked Partial tag documentation about passing data. Check how the issue’s view:class example fits the Cascade behavior, then document the recommended approach if confirmed. Done means the docs explain how to prevent a nested partial from inheriting a parent’s class value.

描述

Often partials use a param called class and are nested. In that case, I don't want to use the parent class data in a nested partial that doesn't receive class itself:

{{# The parent partial receives a class. #}}
{{ partial:parent class="some-class" }}
{{#
    @name Parent
    @param class Custom CSS classes.
#}}

{{# No class passed to the child. #}}
<div :$class>
    {{ partial:child }}
</div>
{{#
    @name Child
    @param class Custom CSS classes.
#}}

{{# Since class is null, the Cascade would look upwards until it finds class data. #}}
<div :$class>
    I am a child.
</div>

My solution here was to use view:class. The nested partial doesn't receive the parent's class data anymore. I don't know if this is the intended use case (besides that).

I would either add this as a "best practice" (like in the linked docs article) to the Data Inheritance docs page or another solution that might be better.
