用Django上传大文件:应该怎么做？

from django.core.files.storage import default_storage

def upload_file(request):
    if request.method == 'POST':
        file = request.FILES.get('file')
        if file:
            # 设置每个分块的大小为2MB
            chunk_size = 2 * 1024 * 1024
            # 获取文件名
            file_name = file.name
            # 生成保存文件的路径
            file_path = f'uploads/{file_name}'
            
            # 逐块保存文件
            with default_storage.open(file_path, 'wb') as destination:
                for chunk in file.chunks(chunk_size):
                    destination.write(chunk)
            
            # 文件保存成功后的处理逻辑
            # ...
            
            return HttpResponse('文件上传成功')
    
    return render(request, 'upload.html')
