Python Django, how to set a secret link in the admin panel?

Question

Django

There is a booleanfield field in the news model, in which if the checkbox is checked, a hash is generated, which is a unique parameter in the URL for a separate news item, if the checkbox is not checked or unchecked, the link is deleted. It all works, but one hash is generated. For example, this one is c63f96d367536fa10914963237616627. But I need the full address to be generated - 127.0.0.1:8000/secret/c63f9654d367536fa10914963237... and that only the hash is added to the model field, and the full address is displayed in the admin panel. How to do it?

Answer 1

Will the link be followed only from the admin panel?
You can add a function to the admin class:

def get_hash_link(self, obj):
    try:
        return mark_safe(u'<a href="/secret/{0}" target="_blank">{0}</a>'.format(obj.hash))
    except:
        return u'Невозможно сформировать ссылку'

and then call her
or from the form

fieldsets = (
        (u'Основные данные', {'fields': (
            'field1',
            'field2',
            'field3',
            'get_hash_link',
            ...
        )}),
