I need to pass values to a dust template in the following manner:
<div class="o-outer">
{>"atoms/button" text="{+filteredClass/}"/}
</div>
{<filteredClass}
{@customFilter _key="MENU" /}
{/filteredClass}
Any idea how to achive this?
I think you will want to define a custom filter instead of a helper with a custom filter. See http://www.dustjs.com/docs/filter-api/ for details on how to create a custom filter. Then you will be able to do:
<div class="o-outer">
{>"atoms/button" text="{text|myFilter}"/}
</div>
This all assumes that your customFilter
helper is actually being used in the same way that Dust filters are used. If not, then you will probably need a different solution.
