分配前在/本地变量'user'处引用了UnboundLocalError

Question

I'm using django-favorite, https://bitbucket.org/last_partizan/django-favorites and trying to display "Get only blogpost favorites for user" strategy to get my favorites. in documentation, it says

content_type = get_object_or_404(ContentType, app_label='myblogapp', model='blogpost')
favs = Favorite.objects.favorites_for_user(user).filter(content_type=content_type)

will do the job. So in my views.py I have added

def index(request):
        user = MyProfile.objects.get(username=user)

        categories = Category.objects.all()
        try:
                sort = request.GET["sort"].strip()
                sort_method = SortMethods[sort]
                page = request.GET["page"].strip()
        except KeyError:
                sort_method = SortMethods.score
                page = 1

        if sort_method == SortMethods.date:
                post_list = Post.objects.order_by("-pub_date")
        else:
                post_list = Post.objects.all()
                post_list = sorted(post_list, key=lambda x: x.get_score(), reverse=True)

        paginator = Paginator(post_list, 30)

        try:
                posts = paginator.page(page)
        except PageNotAnInteger:
                posts = paginator.page(1)
        except EmptyPage:
                posts = paginator.page(paginator.num_pages)

        content_type = get_object_or_404(ContentType, app_label='main', model='post')
        favs = Favorite.objects.favorites_for_user(user).filter(content_type=content_type)
        context = {
                "posts": posts,
                "pages": paginator.page_range,
                "sort": sort_method.name,
                "categories":categories,
                "favs":favs,

        }
        return render(request, "main/index.html", context)

and to use that fav in my index.html, I have simply put {{fav}}, I'm not even sure this is the right way to call the favorites. But I tried and now it gives me UnboundLocalError at /

local variable 'user' referenced before assignment that's coming from ` user = MyProfile.objects.get(username=user)

` I have userena app, inside userena model

  class MyProfile(UserenaBaseProfile):
    user = models.OneToOneField(User,
                                unique=True,
                                verbose_name=_('user'),
                                related_name='my_profile')
    intro = models.CharField(_('intro'),
                                       max_length=5, default="Hello")

I'm calling from here to get user...I hope this is right.

Answer 1

Should that first line be using:

request.user

So like this:

user = MyProfile.objects.get(username=request.user)
