DJANGO - Admin Action

Question

I'd like to create a website with for car dealer with admin and allow dealers to add, edit, delete car.

My problem is that on Django Admin, when I login with any account I see all the cars and I'd like to show only cars attched to connected dealer.

I create a model

from django.db import models
from django.contrib.auth.models import User
import datetime
from brand.models import Brands
from django.urls import reverse

class Car(models.Model):
 dealer = models.ForeignKey(User, on_delete=models.DO_NOTHING)
 brand = models.ForeignKey(Brands, on_delete=models.DO_NOTHING)
 carname = models.CharField(max_length=100)
 def __str__(self):
 return '%s %s' % (self.brand, self.carname)

Also, when I create a car the dealer's list show all dealers in database, but me I'd like to display only connected account name.

Thanks for your help

In Django Admin class you can define has_view_permission method https://docs.djangoproject.com/en/3.2/ref/contrib/admin/#django.contrib.admin.ModelAdmin.has_view_permission

for example:

class CarAdmin(admin.ModelAdmin):
    def has_view_permission(request, obj=None):
        if request.user == obj.dealer:
            return True
        else:
            return False
