python - 如何删除django中的用户？

Question

这听起来可能是个愚蠢的问题，但我很难使用此 View 在 django 中删除用户:

@staff_member_required 
def del_user(request, username):    
    try:
        u = User.objects.get(username = username)
        u.delete()
        messages.sucess(request, "The user is deleted")
    except:
      messages.error(request, "The user not found")    
    return render(request, 'front.html')

在 urls.py 中我有

url(r'^del_user/(?P<username>[\w|\W.-]+)/$', 'profile.views.del_user'), 

我得到的是 The user not found 而不是用户被删除。

这里有什么问题吗？

您应该将代码更改为:

@staff_member_required 
def del_user(request, username):    
    try:
        u = User.objects.get(username = username)
        u.delete()
        messages.success(request, "The user is deleted")            

    except User.DoesNotExist:
        messages.error(request, "User doesnot exist")    
        return render(request, 'front.html')

    except Exception as e: 
        return render(request, 'front.html',{'err':e.message})

    return render(request, 'front.html') 

并在模板中显示 err 以查看更多错误消息
