"在下拉选择名称中加载外键数据太慢"

Question

I'm trying to show foreign key data as a drop down list, but we have a big data, the problem is it takes too long to load page that has the drop down field with the foreign key, is there a way to load it part by part? here is my models.py

class Vistor(models.Model):
admin = models.ForeignKey(User,on_delete=models.PROTECT,default=1)
full_name = models.CharField(max_length=150,verbose_name=_('full name'))
dob = models.DateField(max_length=14,verbose_name=_('dob'))
city = models.ForeignKey(City,on_delete=models.CASCADE,verbose_name=_('city'))

class Meta:
    constraints = [
        models.UniqueConstraint(fields=['full_name','dob','city'],name='full_information')
    ]

def __str__(self):
    return f'{self.full_name} - {self.city} - {self.dob}'

You can use django-autocomplete-light<\/a> along with leveraging Django forms to display that element.
