姜戈 |我想向"匿名用户"显示页面，即使我在 views.py 中使用request.user

Question

我想向所有用户显示页面，即使他们没有登录，但因为我在views.py中使用request.user，这是不可能的。

有办法处理这个吗?

views.py:

class ServerView(View):
def get(self, request, server_tag):
server = Server.objects.get(tag=server_tag)
posts = server.posts.all()
is_following = False
relation = ServerFollow.objects.filter(server=server, user=request.user)
if relation.exists():
is_following = True
return render(request, 'servers/server.html', {'server':server, 'posts':posts, 'is_following':is_following})

Answer 1

检查请求用户是否经过身份验证。在此基础上，你可以实现链式过滤。

class ServerView(View):
def get(self, request, server_tag):
server = Server.objects.get(tag=server_tag)
posts = server.posts.all()
is_following = False
qs = ServerFollow.objects.filter(server=server)
if qs and request.user.is_authenticated():
qs = qs.filter(user=request.user)
if qs:
is_following = True
return render(request, 'servers/server.html', {'server':server, 'posts':posts, 'is_following':is_following})
