MEDIA_ROOT = '/path/to/media/folder'
MEDIA_URL = '/media/'

from django.db import models

class MyModel(models.Model):
    image = models.ImageField(upload_to='images/')

from django.core.files.uploadedfile import InMemoryUploadedFile
from django.http import HttpResponseBadRequest

def my_view(request):
    if request.method == 'POST':
        image_file = request.FILES.get('image')
        if isinstance(image_file, InMemoryUploadedFile):
            # 保存图像文件
            my_model = MyModel()
            my_model.image.save(image_file.name, image_file)
            my_model.save()
            return HttpResponse('Image saved successfully.')
        else:
            return HttpResponseBadRequest('Invalid image file.')

from django.urls import path
from .views import my_view
