我有一个网站，我们下载了一个xl文件，我有我的看法如下，而不是返回excel文件，其返回的文本文件与名称的对象内，我如何解决这个问题

views.py：

def my_view(request):
 obj = model.objects.first()
    response = HttpResponse(file, content_type=' 
  application/vnd.ms-excel',
                                )
    return response

url.py：

path('temo/fill',views.my_view,name = 'my-view')

models.py

class Model(BaseModel, SingletonModel):
    file = models.FileField(
        upload_to='',
        validators=[FileExtensionValidator([''])]
    )
    person_uploaded = models.ForeignKey(
        'somemodel',
        related_name='s',
        null=True,
        on_delete=models.SET_NULL,
        )

admin.py：

@admin.register(tTemplate)
class TemplateAdmin(admin.ModelAdmin):
    list_display = ('file','person_uploaded',)
    readonly_fields = ('person_uploaded',)

    def save(self, request):
        if not self.id:
            self.person_uploaded = request.user
        super().save()
