Hi all,
I’m sorry if this is a really silly question. I’m creating my first theme app extension and app block.
I’m trying to access a metafield that our app creates on installation. At the moment I’m hardcoding the app id as follows:
{% assign modifier_list = product.metafields.app--xxxxxxxxxxx--xxxxx.assigned_modifiers_set_list.value %}
But it’s kinda annoying when switching between development apps needing to update the app id all the time.
I thought that I could possibly use the app object to do something like this:
{% assign modifier_list = product.metafields.app.assigned_modifiers_set_list.value %}
Is there an object or property available that allows app blocks to access it’s own app id for use in metafields?
Thank you so much,
daniel

Currently, there isn’t a built-in way to dynamically reference your app’s ID in Liquid.
To make life a bit easier during development, you might consider storing the app ID in a block or theme setting and then use that to build your metafield namespace dynamically:
{% assign namespace = "app--" | append: block.settings.app_id %}
{% assign modifier_list = product.metafields[namespace].assigned_modifiers_set_list.value %}
This way, you only need to update the setting in one place (or have different settings for dev/staging/production).

Hey Daniel,
Thank you very much for your reply and detailed solution, it’s very much appreciated
I’m assuming user can overwrite this, no? Won’t this be is an issue if user overwrite it in production?
