int（）以10為底的無效字面量：“ aa”，我沒有嘗試傳遞數字，為什么會得到這個？

Question

您好，我是django活動流，收到以下錯誤消息：當我嘗試遵循名為aa的類別時，int（）的無效字面量為10。 這是我的代碼

def category_timeline(request, category):
    user = User.objects.select_related('profile').get(category=category)
    user_actions = []

    if is_following(request.user, user) or not user.profile.private:
        user_actions = actor_stream(user)

    context = {
        'user': user,
        'activities': user_actions,
    }
    return render(request, 'timeline.html', context)


def follow_user(request, category):
    follow(request.user, User.objects.get(category=category))
    return redirect('category_timeline', category)

def unfollow_user(request, category):
    unfollow(request.user, User.objects.get(category=category))
    return redirect('category_timeline', category)

這是我的回溯

這是從這里發生的user = User.objects.select_related('profile').get(category=category)我不確定我是否做對了。 我想做的是顯示用戶以遵循類別，並顯示類別的內容。 我有類別模型和類別視圖，看起來像這樣

def category(request, category_name_url):
    user = User.objects.get(username=request.user)
    category_name = decode_url(category_name_url)


    category = Category.objects.get(name=category_name)

發表以上討論的最終結論

在此調用User.objects.get(category=category))它期望Category模型的主鍵而不是字符串。

所以像下面的事情應該工作

category_id = Category.objects.get(name=category)
User.objects.get(category=category_id))
