There is such a table

How to pull out all the levels of portals and count the number of identical levels using django orm?
models.py

class InvPortal(models.Model):
    user_portal = models.ForeignKey(User,on_delete=models.CASCADE)

    portal_name = models.CharField(max_length=65,default='Портал')
    portal_level = models.IntegerField(default=1)
    portal_xp_reward = models.IntegerField(default=100)
    portal_silver_reward = models.IntegerField(default=250)
    portal_info = models.TextField(default='Инфо',max_length=300)
    portal_unique_id = models.CharField(max_length=65,default=unique_id)
    portal_time_taken = models.IntegerField(default=15)
    portal_selected = models.BooleanField(default=False)
    
    def __str__(self):
        return self.portal_name

The output would be something like

level_18 = 5 # 5 = количество порталов
level_7 = 2 # 2 = количество порталов
