Экспорт одного элемента в csv Django

У меня есть модель под названием leads и я пытаюсь экспортировать одну ссылку из моей базы данных. В настоящее время я могу экспортировать только все зацепки.

Model.py

class Lead(models.Model):
   transfer_date=models.DateField(blank=True, null=True)
   callback_date = models.DateField(blank=True, null=True)
   contact_date = models.DateField(blank=True, null=True)
   first_name = models.CharField(max_length=20)
   last_name = models.CharField(max_length=20)
   address = models.CharField(default=0, max_length=50)
   city = models.CharField(max_length=30, default="")
   state = models.CharField(max_length=20, default="")
   zipcode = models.IntegerField(default=0)
   phone = models.CharField(max_length=10, null=True, default="", blank=True)
   cell = models.CharField(max_length=10, null=True, default="", blank=True)
   email = models.EmailField(default="")

   def __str__(self):
    return f"{self.first_name} {self.last_name}"

Views.py

def export(request):
   response = HttpResponse(content_type='text/csv')
   writer = csv.writer(response)
   writer.writerow(['First Name', 'Last Name', 'Email'])

   for lead in Lead.objects.all().values_list('first_name', 'last_name', 'email'):
    writer.writerow(lead)

   response['Content-Disposition'] = 'attachment; filename="Lead.csv"'

   return response

def export_single_lead(request):
   response = HttpResponse(content_type='text/csv')
   writer = csv.writer(response)
   writer.writerow(['First Name', 'Last Name', 'Email'])

   lead = Lead.objects.last()  # Or get the lead you want some other way
   writer.writerow((lead.first_name, lead.last_name, lead.email))

   response['Content-Disposition'] = 'attachment; filename="Lead.csv"'

   return response

def export(request, pk):
   response = HttpResponse(content_type='text/csv')

   writer = csv.writer(response)
   writer.writerow(['First Name', 'Last Name', 'Email'])


   lead = Lead.objects.get(id=pk)
   writer.writerow((lead.first_name, lead.last_name, lead.email))

  
   response['Content-Disposition'] = 'attachment; filename="Lead.csv"'

   return response
