model.py

class Post(models.Model):
      owner = models.ForeignKey(User,on_delete=models.CASCADE,related_name="posts",blank=False,null=False)
      </other fields>...

class PostImage(models.Model):
      owner = models.ForeignKey(Post,on_delete=models.CASCADE,related_name="images",blank=False,null=False)

views.py

def example(request):
    context = {
        'hellow we':"qfqf"
    }
    print(request.user)
    PostFormSet = inlineformset_factory(User, Post, fields=('longitude', 'latitude', 'placename', 'explanation', ))
    print("------------------------------------------------------------")
    print(frm.errors)
    return JsonResponse(context, encoder=JSONEncoder)
