Update product metafield when a product has incoming inventory

[daveuk100]

The overall goal is to show a badge on every product listing like "restocking soon" if the product has inventory.incoming > 0 (e.g. a purchase order has been created and the product has incoming stock on it's way).

I don't want to use a 3rd party app for this, and I want to avoid modifying liquid directly in my templates (today I do this, and am I trying to avoid it moving forward...).

Today, I modify my prestige template theme (product-badges.liquid) to have an extra piece of code:

  {% if variant.available == false and variant.incoming %}
    <span class="badge badge--custom">Restocking soon</span>
  {% endif %}

I want to avoid that custom code in the template. I use prestige theme and it has a feature where every product has a metafield called "badges". Any text you put into that metafield will show up on the product listing as a badge (so this is essentially a way of adding custom badges to a product in addition to the defaults like "sold out" etc).

I am hoping that there is some automated way (e.g. via Flow) to make it so that whenever a product's "variant.incoming" value is > 0 , the badges metafield on that product is updated to say "Restocking soon". 

Can flow do this? either by acting on product update or purchase order creation?

Thanks.

If i remember correctly, unfortunately Flow does not have relevant triggers.

Other apps do, for example Mechanic has a very similar task https://tasks.mechanic.dev/auto-tag-products-with-incoming-inventory 

I totally support your desire to avoid theme code edits to make it easier to update your theme in future.

In your case, I believe you may rather use "Liquid block" to add very similar liquid code:

  {% assign variant = product.selected_or_first_available_variant %}

  {% if variant.available == false and variant.incoming %}
    <span class="badge badge--custom">Restocking soon</span>
  {% endif %}

Thanks Tim! Appreciate all the guidance.

I agree that's a good solution for the product page badges, but unfortunately the place where I need to see this badge is on the product "cards" that get displayed when you visit a collection page. I am not sure if there is any way to achieve that with a liquid block.
