我可以看到问题,我附上了我的代码和错误页面。
在我的模板中,我有:
{% if user.get_profile.is_store %}
<!--DO SOME LOGIC-->
{%endif%}
在我看来,我有:
def downloads(request):
"""
Downloads page, a user facing page for the trade members to downloads POS etc
"""
if not authenticated_user(request):
return HttpResponseRedirect("/professional/")
if request.user.get_profile().is_store():
return HttpResponseRedirect("/")
user = request.user
account = user.get_profile()
downloads_list = TradeDownloads.objects.filter(online=1)[:6]
downloads_list[0].get_thumbnail()
data = {}
data['download_list'] = downloads_list
return render_to_response('downloads.html', data, RequestContext(request))

答案 0 :(得分:3)
self.account
在尝试处理Account
时指向不存在的is_store()
对象。我猜你正在使用一个不强制执行外键的数据库*咳嗽* MySQL *咳嗽*,你的数据搞砸了。
答案 1 :(得分:0)
看起来user.get_profile()返回值为空,因此在下一次is_store()调用时失败:
return not self.account is None
失败了,因为自己是空的(即无)。
[edit]阅读this(在“个人档案”下)后,看起来该用户的个人资料不存在,因此您获得了DoesNotExist异常。
答案 2 :(得分:0)
不是重定向不起作用 - 它是您的is_store()过程或不存在的配置文件。你应该检查self.account引用到底是什么。
据我所知,通过查看代码,您的数据库中有两个表 - 一个用于baseaccount,仅存储用户ID,而account用于存储与account + baseaccount id关联的所有字段。你可以尝试用这样的东西替换is_store
def is_store(self):
try:
return self.account is None
except Account.DoesNotExist:
return False
我绝不是Django专家,但我认为这可以解决问题。
