如何在 django 的 Replace function 中使用正则表达式

Question

I'm trying to update all urls in my query by using django's update and Replace function using regex. Here's what I've tried so far but it seems like django's Value expression did not recognize my regex.

from django.db.models import Value
from django.db.models.functions import Replace

Foo.objects.filter(
    some_url__iregex=r'^\/some-link\/\d+\/').update(
    some_url=Replace(
        'some_url', Value(r'^\/some-link\/\d+\/'),
        Value('/some-link/')))

My goal is to remove all numbers after /some-link/ (eg /some-link/55/test to just /some-link/test )

I wasn't able to get the Replace function from Django working, but I was able to use the Function for REGEXP_REPLACE detailed in this answer: https://stackoverflow.com/a/68402017/3056056
