我想用一些基本表單數(shù)據(jù)+一個(gè)或多個(gè)上傳的文件對(duì)表單進(jìn)行反序列化。如果我發(fā)送以下請(qǐng)求（使用 Postman 作為 Python 請(qǐng)求代碼生成）import requestsurl = "http://127.0.0.1:8000/forms/test/"payload = {'customer_id': '123456789','customer_name': 'Billy Bob'}files = [ ('files', open('/C:/tmp/aaaaa.csv','rb')), ('files', open('/C:/tmp/bbbbb.csv','rb'))]headers= {}response = requests.request("POST", url, headers=headers, data = payload, files = files)print(response.text.encode('utf8'))該代碼返回以下響應(yīng)（我希望它會(huì)保存文件）。{ "files": [ "This field is required." ]}楷模from datetime import datetimefrom django.db import modelsclass Mtfar(models.Model): date = models.DateTimeField(auto_now_add=True) customer_id = models.IntegerField() customer_name = models.CharField(max_length=254)class MtfarFile(models.Model): file = models.FileField(blank=False, null=False) mtfar = models.ForeignKey(Mtfar, related_name='files', on_delete=models.CASCADE)序列化器from rest_framework import serializersfrom .models import Mtfar, MtfarFileclass MtfarFileSerializer(serializers.ModelSerializer): class Meta: model = MtfarFile fields = ['file']class MtfarSerializer(serializers.ModelSerializer): files = MtfarFileSerializer(many=True) class Meta: model = Mtfar fields = ['customer_ptid', 'customer_name', 'files']

您需要將QueryDict對(duì)象轉(zhuǎn)換為 adict以支持嵌套序列化，因?yàn)?DRFQueryDict以不同的方式解析 a 。
@api_view(['POST'])
@parser_classes([MultiPartParser])
def post_generic_form(request):
? ? dict_data = {
? ? ? ? **request.data.dict(),
? ? ? ? **{"files": [{"file": file} for file in request.FILES.getlist('files')]}
? ? }
? ? serializer = MtfarSerializer(data=dict_data)
? ? if serializer.is_valid():
? ? ? ? serializer.save()
? ? ? ? return Response(status=status.HTTP_201_CREATED)
? ? else:
? ? ? ? return Response(serializer.errors, status=status.HTTP_400_BAD_REQUEST)
