【问题描述】:
嘿,是否可以从 django 中的模型方法中获取 request.session 值?
重大更新
这是我的模型
class GameDiscussion(models.Model):
game = models.ForeignKey(Game)
message = models.TextField()
reply_to = models.ForeignKey('self', related_name='replies', null=True, blank=True)
created_on = models.DateTimeField(blank=True, auto_now_add=True)
userUpVotes = models.ManyToManyField(User, blank=True, related_name='threadUpVotes')
userDownVotes = models.ManyToManyField(User, blank=True, related_name='threadDownVotes')
votes = models.IntegerField()
def html(self):
DiscussionTemplate = loader.get_template("inclusions/discussionTemplate")
return DiscussionTemplate.render(Context({
'discussion': self,
'replies': [reply.html() for reply in self.replies.all().order_by('-votes')]
}))
def _find_users_who_have_voted(self):
user_list = []
for user in self.userDownVotes.all():
user_list.append(user.id)
for user in self.userUpVotes.all():
user_list.append(user.id)
return user_list
users_voted = property(_find_users_who_have_voted)
我的视图是这样调用的
<ul>
{% for discussion in discussions %}
{{ discussion.html }}
{% endfor %}
</ul>
和模板
<li>
<small>
({{ discussion.votes }} votes)
{% if user_id not in discussion.users_voted %}
user not in list!
{% endif %}
</small>
<strong>{{ discussion.message }}</strong>
{% if replies %}
<ul>
{% for reply in replies %}
{{ reply }}
{% endfor %}
</ul>
{% endif %}
值“user_voted”返回对此讨论投票的用户 ID 列表。
我想看看 request.session['user'].id 值是否在这个列表中
