Creating Custom Display Fields in Django Admin (that don't exist in models.py)

I have two fields in models.py

numberOfUsers = IntegerField()
numberOfUserCredits = IntegerField()

In Django admin, instead of viewing two columns with

list_display = ['numberOfUsers', 'numberOfUserCredits']

I'd like to instead clean this up a bit and concatenate these two fields for simpler viewing:

str(numberOfUsers) + '/' + str(numberOfUserCredits)

How can I create a custom field like this in Django admin? I could create a new field in models.py that creates this field automatically on model save, but I am wondering if there is an easier way to go about doing this.

I found a similar question already asked, but the answer below was exactly what I was looking for.

You can add it to your ModelAdmin class something like following, also i would suggest using f strings instead of concatenation

class SomeAdmin(admin.ModelAdmin):
    list_display = (..., 'user_field')

    def user_field(self, obj):
        return f'{obj.numberOfUsers}/{obj.numberOfUserCredits}'
    user_field.short_description = 'userShort'
