Django REST UnitTest沒有提交文件

我成功地實施了小案例。然後我開始採用更大的結構。我得到了錯誤。
錯誤：
No file was submitted.Django REST UnitTest沒有提交文件

import tempfile 
from unittest import skip 

from django.conf import settings 
from django.contrib.auth.models import User 
from django.core.files import File 
from django.core.files.uploadedfile import SimpleUploadedFile 
from model_mommy import mommy 
from rest_framework import status 
from rest_framework.reverse import reverse 
from rest_framework.test import APITestCase, APIClient 


class CustomerFromExcelViewsetTest(APITestCase): 
    def setUp(self): 
     self.client = APIClient() 
     self.soken_staff = mommy.make(User, username='spearhead') 
     self.user = mommy.make(User, username='Justin') 
     settings.MEDIA_ROOT = tempfile.mkdtemp() 

    def test_upload_file(self): 
     """Expect created_user, and updated_user correct set""" 
     file = File(open('./soken_web/apps/uploaded_files/complete-customer.xlsx', 'rb')) 
     uploaded_file = SimpleUploadedFile('new_excel.xlsx', file.read(), content_type='multipart/form-data') 
     data = { 
      file: uploaded_file, 
     } 
     self.client.force_authenticate(user=self.user) 
     response = self.client.post(reverse('api:customer_from_excel-list'), data, format='multipart') 
     response.render() 

     self.assertEqual(status.HTTP_201_CREATED, response.status_code)

在這裏，他們是models，serializers和viewsets

models.py

serializers.py

viewsets.py

一天之後，我想不出哪裏是這個bug。
