python - django 错误(外部 IP)

Question

每次输入不存在的地址时，我都会收到通知。

Traceback (most recent call last): File "/home/user/opt/local/django/core/handlers/base.py", line 100, in get_response File "/web/blog/views.py", line 33, in post File "/home/user/local/django/db/models/manager.py", line 132, in get File "/home/user/opt/local/django/db/models/query.py", line 347, in get DoesNotExist: Post matching query does not exist.

如何解决

Answer 1

修改您的查询以使用 get_object_or_404 , 或者 catch YourModel.DoesNotExist (第 3 段)进行查找时出现异常，并引发 Http404异常(exception)。当您没有捕捉到 DoesNotExist 异常时， View 会引发 500 错误。作为副作用，这会向 ADMINS 发送异常电子邮件。定义它 settings.py。

两种情况的例子:

from django.shortcuts import get_object_or_404

post_id = 1
post = get_object_or_404(Post, id=post_id)

# or catch the exception and do something with it

from django.http import Http404
try:
    post = Post.objects.get(id=post_id)
except Post.DoesNotExist:
    # id doesnt exist... do extra things here
    raise Http404
