如何在django rest中保存文件

from django.db import models

class MyModel(models.Model):
    file = models.FileField(upload_to='uploads/')

from rest_framework import serializers
from .models import MyModel

class MyModelSerializer(serializers.ModelSerializer):
    class Meta:
        model = MyModel
        fields = ('id', 'file')

from rest_framework import views
from rest_framework.parsers import MultiPartParser, FormParser
from rest_framework.response import Response
from .serializers import MyModelSerializer

class FileUploadView(views.APIView):
    parser_classes = (MultiPartParser, FormParser)

    def post(self, request, format=None):
        serializer = MyModelSerializer(data=request.data)
        if serializer.is_valid():
            serializer.save()
            return Response(serializer.data, status=201)
        else:
            return Response(serializer.errors, status=400)

from django.urls import path
from .views import FileUploadView

urlpatterns = [
    path('upload/', FileUploadView.as_view()),
]

pip install djangorestframework django-filter

from django.db import models

class MyModel(models.Model):
    file = models.FileField(upload_to='uploads/')

from rest_framework import serializers
from .models import MyModel

class MyModelSerializer(serializers.ModelSerializer):
    class Meta:
        model = MyModel
        fields = ('id', 'file')

from rest_framework import viewsets
from .serializers import MyModelSerializer

class MyModelViewSet(viewsets.ModelViewSet):
    queryset = MyModel.objects.all()
    serializer_class = MyModelSerializer

from django.urls import path, include
from rest_framework.routers import DefaultRouter
from .views import MyModelViewSet

router = DefaultRouter()
router.register(r'mymodels', MyModelViewSet)

urlpatterns = [
    path('', include(router.urls)),
]
