嗨,Djangonauts, 我正在尝试在模板中获取用户关注列表(例如,Instagram的“ A”跟随“ B”之类的示例)。我已经尝试了几乎所有无法在模板中调用的内容。我在做什么错了
我的模型(这是Django用户模型的猴子补丁)
class Profile(models.Model):
user = models.OneToOneField(User, on_delete=models.CASCADE)
#other profile fields
class Contact(models.Model):
user_from = models.ForeignKey(User, related_name='supporter')
user_to = models.ForeignKey(User, related_name='leader')
def __str__(self):
return '{} follows {}'.format(self.user_from, self.user_to)
User.add_to_class(
'following',
models.ManyToManyField(
'self',
through=Contact,
related_name='followers',
symmetrical=False))
我的观点(不确定是否正确)
def get_context_data(self, **kwargs):
context = super(ProfileView, self).get_context_data(**kwargs)
context['follows'] = Contact.objects.filter(
user_from__isnull=False,
user_from__username__iexact=self.kwargs.get('username'))
context['followers'] = Contact.objects.filter(
user_to__isnull=False,
user_to__username__iexact=self.kwargs.get('username'))
return context
我的模板
{{user}} follows {{user.supporter.count}} members #This works shows the correct number
{% for contact in Contact.objects.all %}
{{contact.user_to.username}} # I am not able to get this part to work
{% endfor %}
答案 0 :(得分:1)
无效的位是循环,因为模板中未定义Contact
。但是我不明白为什么您认为需要访问它。您应该遍历用户的“多对多”字段:
{% for follow in user.following.all %}
{{ user.username }}
{% endfor %}
