我正在为一个假想的社交网络编写聊天应用程序，但当我尝试打开聊天页面时，出现了“AnonymousUser”对象没有属性“profile”的错误。
我认为问题可能在models文件中，但我真的无法弄清楚如何修复它，现在我很困惑！ 有人可以给任何建议吗？
聊天views.py的部分内容：
聊天views.py的部分内容：
def index(request):
if request.method == 'POST':
print request.POST
request.user.profile.is_chat_user=True
logged_users = []
if request.user.username and request.user.profile.is_chat_user:
context = {'logged_users':logged_users}
cu = request.user.profile
cu.is_chat_user = True
cu.last_accessed = utcnow()
cu.save()
return render(request, 'djangoChat/index.html', context)
try:
eml = request.COOKIES[ 'email' ]
pwd = request.COOKIES[ 'password' ]
except KeyError:
d = {'server_message':"You are not logged in."}
query_str = urlencode(d)
return HttpResponseRedirect('/login/?'+query_str)
try:
client = Vertex.objects.get(email = eml)
context = {'logged_users':logged_users}
cu = request.user.profile
cu.is_chat_user = True
cu.last_accessed = utcnow()
cu.save()
if client.password != pwd:
raise LookupError()

def chat_api(request):
if request.method == 'POST':
d = json.loads(request.body)
msg = d.get('msg')
user = request.user.username
gravatar = request.user.profile.gravatar_url
m = Message(user=user,message=msg,gravatar=gravatar)
m.save()
res = {'id':m.id,'msg':m.message,'user':m.user,'time':m.time.strftime('%I:%M:%S %p').lstrip('0'),'gravatar':m.gravatar}
data = json.dumps(res)
return HttpResponse(data,content_type="application/json")
# get request
r = Message.objects.order_by('-time')[:70]
res = []
for msgs in reversed(r) :
res.append({'id':msgs.id,'user':msgs.user,'msg':msgs.message,'time':msgs.time.strftime('%I:%M:%S %p').lstrip('0'),'gravatar':msgs.gravatar})
data = json.dumps(res)
return HttpResponse(data,content_type="application/json")
def logged_chat_users(request):
u = Vertex.objects.filter(is_chat_user=True)
for j in u:
elapsed = utcnow() - j.last_accessed
if elapsed > datetime.timedelta(seconds=35):
j.is_chat_user = False
j.save()
uu = Vertex.objects.filter(is_chat_user=True)
d = []
for i in uu:
d.append({'username': i.username,'gravatar':i.gravatar_url,'id':i.userID})
data = json.dumps(d)
return HttpResponse(data,content_type="application/json")
以及我的聊天模型的部分内容：
class Message(models.Model):
user = models.CharField(max_length=200)
message = models.TextField(max_length=200)
time = models.DateTimeField(auto_now_add=True)
gravatar = models.CharField(max_length=300)
def __unicode__(self):
return self.user
def save(self):
if self.time == None:
self.time = datetime.now()
super(Message, self).save()
def generate_avatar(email):
a = "http://www.gravatar.com/avatar/"
a+=hashlib.md5(email.lower()).hexdigest()
a+='?d=identicon'
return a
def hash_username(username):
a = binascii.crc32(username)
return a
# the problem seems to be here ??!
User.profile = property(lambda u: Vertex.objects.get_or_create(user=u,defaults={'gravatar_url':generate_avatar(u.email),'username':u.username,'userID':hash_username(u.username)})[0])
最后是另一个应用程序(ChatUsers)的部分：
class Vertex(models.Model,object):
user = models.OneToOneField(User)
password = models.CharField(max_length=50)
#user_id = models.CharField(max_length=100)
username = models.CharField(max_length=300)
userID =models.IntegerField()
Message = models.CharField(max_length=500)
firstname = models.CharField(max_length=50)
lastname = models.CharField(max_length=50)
email = models.EmailField(max_length=75)
is_chat_user = models.BooleanField(default=False)
gravatar_url = models.CharField(max_length=300,null=True, blank=True)
last_accessed = models.DateTimeField(auto_now_add=True)
