[Fixed]-Django model for city and places

You can simply remove city field from your Property class because location contains city in it.

To retrieve property city you can do something like this:

models.py

class Property(models.Model):
    # *Your codes here*

    # *define new method*
    def get_city(self):
        return self.location.city()

And then you can use this method every where you need:

admin.py

class PropertyAdmin(admin.ModelAdmin):
    list_display = ['title', 'slug', 'address', get_city, 'status']

or:

>>> A = Property.objects.get(id = 1)
>>> A.get_city()
