Image Uploading

Step-by-Step Guide

Setting Up the Serializer:

from rest_framework import serializers

class ImageUploadSerializer(serializers.Serializer):
    thumbnail = serializers.ImageField()

Creating the View: In the view, handle the file upload and save it to the desired location.

from django.conf import settings
from django.utils.crypto import get_random_string
from rest_framework.views import APIView
from rest_framework.response import Response
from rest_framework.parsers import MultiPartParser, FormParser
from .serializers import ImageUploadSerializer
import os

class ImageUploadView(APIView):
    parser_classes = (MultiPartParser, FormParser)

    def post(self, request, *args, **kwargs):
        serializer = ImageUploadSerializer(data=request.data)
        if serializer.is_valid():
            thumbnail = request.FILES.get('thumbnail')

            if thumbnail:
                # Generate a unique filename
                unique_filename = get_random_string(length=10)
                file_name = f"{unique_filename}_{thumbnail.name}"
                relative_path = os.path.join('public_html', 'media', 'notifications', file_name)
                file_path = os.path.join(settings.BASE_DIR, relative_path)

                # Save the file
                with open(file_path, 'wb+') as destination:
                    for chunk in thumbnail.chunks():
                        destination.write(chunk)

                image_url = f"https://domain.com/media/notifications/{file_name}"
                return Response({"image_url": image_url}, status=200)

        return Response(serializer.errors, status=400)

Configuring URLs: Add the view to your urls.py.

from django.urls import path
from .views import ImageUploadView

urlpatterns = [
    path('upload/', ImageUploadView.as_view(), name='image-upload'),
]

Settings: Ensure that you have the MEDIA_URL and MEDIA_ROOT properly set in your settings.py.
```
MEDIA_URL = '/media/'
MEDIA_ROOT = os.path.join(BASE_DIR, 'media')
```
