Hi

I want to know How to create a filter of the related object (ForeignKey field) in Adding or Editing page in Admin Site.

**Please guide some code or reference links about this question for me to read more.**

General speaking, It is how to customize in add/edit page on the admin site.

My requirement is that I don’t want to list all company, it has to just filter company.is\_customer =True for dropdown list in Edit/Add Brand page

model.py

```auto
class Company(models.Model):
    company_name = models.CharField('Company Name', max_length=255,unique=True )
    company_address=models.CharField('Company Address',max_length=255 ,null=True, blank=True)
    company_telephone = models.CharField('Company Telephone', max_length=255, null=True, blank=True)
    manager = models.ManyToManyField(Manager)

    is_customer =models.BooleanField('Is Customer',default=True)
    is_subcontractor = models.BooleanField('Is Sub Contractor', default=True)

class DataCenter(models.Model):
    datacenter_name = models.CharField('DataCenter Name', max_length=255)

    company=models.ForeignKey('Company',on_delete=models.CASCADE)
    

```

I’d start with taking a look at the [ModelAdmin.formfield\_for\_foreignkey](https://docs.djangoproject.com/en/3.1/ref/contrib/admin/#django.contrib.admin.ModelAdmin.formfield_for_foreignkey) method to see whether that will work for you.
