我正在尝试部署Django网站以使用应用程序引擎共享笔记。

Everything works fine until I try to upload file to my database, either through app interface or admin interface, as it results in 500 Server error.

当我经历类似的问题时，我知道此错误不是由应用程序引擎引起的，但我真的很困惑，因为它在本地运行良好。

我能够将文件上传到通过云代理连接它的数据库。

我试图检查日志并进行调试，但是没有给出任何线索。

附加信息：我正在使用django 3.0.3

Here is my `views.py` :

from django.shortcuts import render, redirect
from .models  import notes
from .forms import upload
import datetime

# Create your views here.
def home(request):
    context={}
    context["dataset"] = notes.objects.all()
    return render(request, "noteitdown/home.html", context)

def upload_view(request):
    context = {}
    date = datetime.date.today()
    if (request.method == 'POST'):
        form = upload(request.POST, request.FILES)
        if form.is_valid():
            data = form.cleaned_data
            entry = notes(author_name=data["author_name"], date_of_pub=date, department=data["department"], file=data["file"])
            entry.save()
            return redirect('home')
        else:
            print(form.errors)
    form = upload()
    context["form"] = form
    return render(request, "noteitdown/upload.html", context)

def about(request):
    return render(request, "noteitdown/about.html")

my `Models.py` :

from django.db import models

# Create your models here.
class notes(models.Model):
    author_name = models.CharField(max_length=20)
    date_of_pub = models.DateField()
    department = models.CharField(max_length=20)
    file = models.FileField(upload_to="storage/")
