Question

我想显示默认头像，但是当我尝试将其保存在数据库文件中时，会使用新名称进行复制。如果文件已存在，如何防止更改文件名？

我的代码： models.py

class UserAccount(User):
    contacts = models.OneToOneField('self', null = True)
    isBanned = models.BooleanField(_('ban status'), default = False,
        help_text = _("Display is contact banned by user."))
    avatar = FileField(upload_to = 'avatars')
   objects = UserManager()

views.py

user = UserAccount.objects.get(username = user_login)
user.first_name = request.POST['first_name']
user.last_name = request.POST['last_name']
user.email = request.POST['email']
try:
    file = request.FILES['avatar']
    fileName = request.FILES['avatar'].name
except:
    fileName = 'static/avatars/default.gif'
    file = File(open(fileName, 'r'))
user.avatar.save(fileName, file)
user.save()

解决方案在于我没有保存头像，而只是将FileField路径用于默认头像。

try:
    file = request.FILES['avatar']
    fileName = request.FILES['avatar'].name
except:
    user.avatar = 'avatars/default.gif'
    flag = False
if flag:
    user.avatar.save(fileName, file)
user.save()
