How to pass data saved from a POST method to the GET method using REST API Django (without a model)? - django

Question

I have created an API that allows me to upload an image using the POST method in POSTMAN. After submission, I want to display that image name after making a GET request. I am not using any model and I don't intend to grab the image from the directory it is stored in; since I will be uploading images in a server later.
I have looked at multiple sources. A few examples are this, and this.
This is my current code so far but not successful:
views.py:
class API(APIView):
parser_classes = (MultiPartParser,)
def get(self, request, *args, **kwargs):
name = self.request.GET.get('image')
if name:
return Response({"img_name": name}, status=200)
return Response({"img_name" : None}, status = 400)
def post(self, request):
file = self.request.data
img_file = file['image'] #store the image data in this variable
if img_file:
uploaded_file = img_file
img = [{"image_name": uploaded_file}]
serializer = ImgSerializer(img, many = True).data
return Response(serializer, status = 200)
else:
return Response("Please upload", status = 400)
serializers.py:
from rest_framework import serializers
class ImgSerializer(serializers.Serializer):
image_name = serializers.CharField()
My expected result within GET request should be like this:
{'image_name' : 'image_name_from_POST_Request'}
But I am getting this result instead:
None
How can I pass data from the POST request to the GET request using Django's rest framework? Is there an efficient way to deploy this requirement without using a model?

I figured it out. I just created a JSON file in the POST method and stored the necessary data in it. Finally, in order to view the data within the GET method, I opened the file and returned it as a Response.
views.py:
class API(APIView):
parser_classes = (MultiPartParser,)
def get(self, request):
with open('data.txt') as json_file:
data = json.load(json_file)
if data:
return Response(data, status=200)
return Response({"name" : None}, status = 400)
def post(self, request):
posted_file = self.request.data
img_file = posted_file['image']
if img_file:
uploaded_file = img_file
data = [{"image_name": uploaded_file}]
json_data = {"image_name": uploaded_file}
data = {}
data['key'] = []
data['key'].append(json_data)
with open('data.txt', 'w') as outfile:
json.dump(image, outfile)
serializer = ImgSerializer(image, many = True).data
return Response(serializer, status = 200)
else:
return Response(serializer.errors, status = 400)
