How to define Permission in the model for a field?

Question

Regular Expressions

Hello everyone, I have such a problem, in my custom user model there is a balance field, I display it in the user profile, but the problem is that any user can change it, and I need only the admin to be able to change the field or the one who has permission is to do permission.
I read that you can add permission to the model in Meta, for example, to edit a field:

class Meta:
        permissions = (
            ("can_edit_meta", "Can edit meta tags"),
        )

But how to use this permission?

Answer 1

(?=^\S+(\s\S+(\s\S+)?)?$)^[а-яА-ЯёЁa-zA-Z0-9\s]+$

Like all other rights

if user.has_perm('your_app.can_edit_meta'):
    # good mojo
else:
    # bad mojo
