int（）的无效文字为10：'aa',,我不想通过号码为什么我得到这个？ [英] invalid literal for int() with base 10: 'aa',,I'm not trying to pass number why am I getting this?

问题描述

你好我是django活动流，我收到这个错误：当我尝试遵循名为aa的类别时，对于int（）的基数为10的无效文字。这是我的代码

  def category_timeline（request，category）：
 user = User.objects.select_related（'profile '）.get（category = category）
 user_actions = [] 
 
如果is_following（request.user，user）或不是user.profile.private：
 user_actions = actor_stream用户）
 
 context = {
'user'：user，
'activities'：user_actions，
} 
 return render（request，'timeline。 html'，上下文）
 
 
 def follow_user（请求，类别）：
跟随（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）
  

这是我的追溯

从这里出现 user = User.objects.select_related（'p rofile'）get（category = category）
我不知道我是否正确地做。我想要做的是显示用户能够遵循类别，并显示类别的内容。
我有类别模型和类别视图
它看起来像这样

  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）

解决方案

从上述讨论中发送最终结论

在此调用中用户。 objects.get（category = category））它正在期待Ca的主键tegory模型而不是字符串。

所以像下面这样的东西应该工作

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

Hello I'm django activity stream, and I got this error: invalid literal for int() with base 10 when I tried to follow category named aa. This is my code

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)

Here's my traceback

It's occuring from here user = User.objects.select_related('profile').get(category=category) I'm not sure if I'm doing it right. What I'm trying to do is to display the users to be able to follow categories, and display the contents of the category. I have category model and category view it looks like this

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)

解决方案

Posting the final conclusion from above discussion

in this call User.objects.get(category=category)) it is expecting primary key of Category model instead of a string.

So something like following should work

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