I want to show a specific customers balance in a panel for that I want to fetch the specific customers balance and want to show it in a page or somewhere else.Like this example:
user 1 has 100$ and user 2 has 200$ so when user 1 will login the page will show 100$ and when user 2 login he will be shown 200$.But I am confused here to complete this task.How can I do this ?
I have a coin var which is working as a balance.
Here is my Model for Customer :

```
class Customer(models.Model):
    phone_number = models.CharField(max_length=100, default=1)
    email = models.EmailField( default=1)
    password = models.CharField(max_length=100)
    coin = models.FloatField(null=True, blank=True)

    def __str__(self):
        return self.phone_number

    def register(self):
        self.save()

    def get_customer(phone_number):
        try:
            return Customer.objects.get(phone_number=phone_number)
        except:
            return False

```
