'AnonymousUser'对象不可迭代？ Django

我正在创建用户创建的所有帖子的摘要页面，并将这些帖子返回到摘要页面。我得到上面的错误？'AnonymousUser'对象不可迭代？ Django

它抱怨这一行：

查看

def aircraft_create(request): 
    form = aircraft_form(request.POST or None) 
    if form.is_valid(): 
    instance = form.save(commit=False) 
    instance.user = request.user 
    instance.save() 
    messages.success(request, "Your upload has been successfully added!") 
    return HttpResponseRedirect(instance.get_absolute_url()) 
    else: 
    messages.error(request, "There seems to be something wrong. Have a look again..!") 
    context = {"form":form,} 
    return render(request,'aircraft/aircraft_form.html', context)

型号

class Aircraft(AircraftModelBase): 
    user = models.ForeignKey(User) 
    manufacturer = SortableForeignKey(Manufacturer) 
    aircraft_type = SortableForeignKey(AircraftType)

查看

def account_overview(request): 
    fav_aircraft = FavoritedAircraft.objects.filter(user__id=request.user.id) 
    fav_airline = FavoritedAirline.objects.filter(user__id=request.user.id) 

    uploaded_aircraft = Aircraft.objects.filter(user=request.user) 

    return render(request,'account/account_overview.html', {'favAircraft':fav_aircraft, 
                  'favAirline':fav_airline, 
                  'UploadedAircraft':uploaded_aircraft})

什么，似乎这里是实际的问题？

如果您有错误，请在您的问题中包含* full * traceback。 – Alasdair

@Alasdair完成！ –

另一方面，你不应该在你的其他过滤器中需要'user_id = request.user.id' user = request.user'应该可以正常工作（只要用户登录）。 – Alasdair

错误是告诉你request.user是匿名用户。这意味着他们没有登录，因此尝试使用filter(user=request.user)进行过滤是没有意义的。

最简单的修复方法是使用login_required装饰器，以确保只有登录用户才能访问该视图。

from django.contrib.auth.decorators import login_required 

@login_required 
def account_overview(request): 
    ...

在我的模板中，我已经有了“{％if user.is_authenticated％} else”Please login“在添加该行后，它将返回一个404.如何获取其他工作？它是否在视图或模板中显示？ –

在模板中进行检查已经太迟了 - 过滤器已经在视图中出现了，login_required装饰器会将用户重定向到登录页面，如果他们没有登录。如果你的LOGIN_URL设置和登录视图是没有正确配置，那么你可能会得到404。如果你不能解决这个问题，那么请提出一个新的问题。 – Alasdair
