Django REST Framework image upload

I lately start Django and have same problem for upload image.

All steps that i done

  1. Install Pillow for using ImageField

    pip install Pillow
    
  2. In Settings.py add these lines

    MEDIA_ROOT = os.path.join(BASE_DIR, 'media')
    MEDIA_URL = '/media/' # 'http://myhost:port/media/'
    
  3. Use ImageField in model.py (create nameFile function for create folder and name of file)

    def nameFile(instance, filename):
        return '/'.join(['images', str(instance.name), filename])
    
    class UploadImageTest(models.Model):
        name = models.CharField(max_length=100)
        image = models.ImageField(upload_to=nameFile, blank=True, null=True)
    
  4. serializer.py

    class ImageSerializer(serializers.ModelSerializer):
        class Meta:
            model = UploadImageTest
            fields = ('name', 'image')
    
  5. views.py

    class ImageViewSet(ListAPIView):
        queryset = UploadImageTest.objects.all()
        serializer_class = ImageSerializer
    
        def post(self, request, *args, **kwargs):
            file = request.data['file']
            image = UploadImageTest.objects.create(image=file)
            return HttpResponse(json.dumps({'message': "Uploaded"}), status=200)
    
  6. urls.py: add this line

    path('upload/', views.ImageViewSet.as_view(), name='upload'),
    
  7. admin.py: add this line (for check in admin)

    admin.site.register(UploadImageTest)
    
  8. in terminal

    python manage.py makemigrations
    python manage.py migrate
    

you can create separate endpoint for uploading images, it would be like that:

class ProductViewSet(BaseViewSet, viewsets.ModelViewSet):
    queryset = Product.objects.all()
    serializer_class = ProductSerializer

    @detail_route(methods=['post'])
    def upload_docs(request):
        try:
            file = request.data['file']
        except KeyError:
            raise ParseError('Request has no resource file attached')
        product = Product.objects.create(image=file, ....)

you can go around that solution
