Create checkbox(choice) from list of django objects?

Question

Django

There are 2 models. The second model has a function that gets all the countries from the first model. I want to make a checkbox from a list of these countries. How to do it?

class GlobalEntry(models.Model):
    country = models.CharField(max_length = 50)
    post_id = models.CharField(max_length=200) 
    data = JSONField() 

    def __str__(self):
        return self.country



class NormalEntry(models.Model):
    def getter(self):
        return GlobalEntry.objects.values('country')

    country = CHECKBOX???
