How to edit the value through the admin panel?

Question

Django

Good time of the day!
Tell me how to change the value through the admin panel
For example, there is a request to display publications for a certain period
There is a filtering by the number of likes

qs = self.get_published()
qs = qs.filter(total_votes__gt=15)

How can I change the value of 15 in the admin panel?

Answer 1

You can make constants:
-> There is a Constant model: title - the name of the constant (unique, text) , value - the value of the constant (null, text)
-> In the code:

constant, created = Constant.objects.get_or_create(title="MIN_LIKES_COUNT")

if created: constant.value = "15"  # По дефолту, чтобы не было ошибок
qs = qs.filter(total_votes__gt=int(constant.value))
