I am able to upload a single image with the following code. If I select multiple images then only the last image among the selected image is getting uploaded.
models.py
class Image(models.Model):
property_id = models.ForeignKey(
'properties.Address',
null=False,
default=1,
on_delete=models.CASCADE
)
image = models.ImageField(upload_to=directory_path)
serializers.py
class ImageSerializer(serializers.ModelSerializer):
class Meta:
model = Image
fields = (
'property_id',
'image'
)
views.py
class ImageView(APIView):
parser_classes = (MultiPartParser, FormParser)
def get(self, request):
all_images = Image.objects.all()
serializer = ImageSerializer(all_images, many=True)
return JsonResponse(serializer.data, safe=False)
def post(self, request, *args, **kwargs):
file_serializer = ImageSerializer(data=request.data)
if file_serializer.is_valid():
file_serializer.save()
return Response(file_serializer.data, status=status.HTTP_201_CREATED)
else:
return Response(file_serializer.errors, status=status.HTTP_400_BAD_REQUEST)
I am a little new to Django. I want to loop over my array of images which is received in the request.data Can anyone tell me how to do it?
So I finally got a workaround in my own way falling back to the basics as I didn't find any way to do it in a DRF way. I hope this answer is helpful to the Django community. I kept my model and serializers same changing the views to iterate over every image and save it using the serializer.
views.py
class ImageView(APIView):
parser_classes = (MultiPartParser, FormParser)
def get(self, request):
all_images = Image.objects.all()
serializer = ImageSerializer(all_images, many=True)
return JsonResponse(serializer.data, safe=False)
def post(self, request, *args, **kwargs):
property_id = request.data['property_id']
# converts querydict to original dict
images = dict((request.data).lists())['image']
flag = 1
arr = []
for img_name in images:
modified_data = modify_input_for_multiple_files(property_id,
img_name)
file_serializer = ImageSerializer(data=modified_data)
if file_serializer.is_valid():
file_serializer.save()
arr.append(file_serializer.data)
else:
flag = 0
if flag == 1:
return Response(arr, status=status.HTTP_201_CREATED)
else:
return Response(arr, status=status.HTTP_400_BAD_REQUEST)
helpers.py
def modify_input_for_multiple_files(property_id, image):
dict = {}
dict['property_id'] = property_id
dict['image'] = image
return dict
models.py
class Image(models.Model):
property_id = models.ForeignKey(
'properties.Address',
null=False,
default=1,
on_delete=models.CASCADE
)
image = models.ImageField(upload_to=directory_path)
serializers.py
class ImageSerializer(serializers.ModelSerializer):
class Meta:
model = Image
fields = (
'property_id',
'image'
)
The request comes in the form of querydict. The line images = dict((request.data).lists())['image']
coverts query dict to python dict and then looping over the array under the 'image'
key.
