Want to print all groups to which user belongs - django

Question

**Models.py**
class User(auth.models.User,auth.models.PermissionsMixin):
def __str__(self):
return "#{}".format(self.username)
def get_absolute_url(self):
return reverse("accounts:login")
class Group(models.Model):
name = models.CharField(max_length = 255,unique = True)
slug = models.SlugField(allow_unicode = True,unique = True)
description = models.TextField(default = '')
members = models.ManyToManyField(User,related_name = "group")
def save(self,*args,**kwargs):
self.slug = slugify(self.name)
super(Group,self).save(*args,**kwargs)
def get_absolute_url(self):
return reverse('groups:single',kwargs = {'slug':self.slug})
def __str__(self):
return self.name
**Views.py**
class ListGroups(ListView):
model = Group
**Html code**
<div class="col-md-8">
<div class="list-group">
{% if user.is_authenticated %}
<h2>Your Groups!</h2>
{% if user.group.count == 0 %}
<p>You have not joined any groups yet! <p>
{% else %}
{% for group in user.group.all %}
<a class="list-group-item" href="{% url 'groups:single' slug=group.slug %}">
<h3 class="list-group-item-heading">{{group.name}}</h3>
<div class="list-group-item-text container-fluid">
{{group.description|safe}}
<div class="row">
<div class="col-md-4">
<span class='badge'>{{group.members.count}}</span>
member{{group.members.count|pluralize}}
</div>
<div class="col-md-4">
<span class='badge'>{{group.posts.count}}</span>
post{{group.posts.count|pluralize}}
</div>
</div>
</div>
</a>
{% endfor %}
{% endif %}
{% endif %}
</div>
According to me it should print all the groups and it's details to which current logined user belongs but it is not printing anything.I have no idea what is wrong in this code.I have tried some other approaches but nothing works.Can anyone help?
Thanks in advance.

Well there is no variable named user in the template, hence all what you wrote will probably not work.
We can however obtain a list of Groups where the logged in user is member of, by first of all modifying the ListsGroup a bit:
from django.contrib.auth.mixins import LoginRequiredMixin
class ListGroups(LoginRequiredMixin, ListView):
model = Group
def get_queryset(self):
return Group.objects.filter(members=self.request.user)
Now we can render this like:
<div class="col-md-8">
<div class="list-group">
<h2>Your Groups!</h2>
{% for group in object_list %}
<a class="list-group-item" href="{% url 'groups:single' slug=group.slug %}">
<h3 class="list-group-item-heading">{{group.name}}</h3>
<div class="list-group-item-text container-fluid">
{{group.description|safe}}
<div class="row">
<div class="col-md-4">
<span class='badge'>{{group.members.count}}</span>
member{{group.members.count|pluralize}}
</div>
<div class="col-md-4">
<span class='badge'>{{group.posts.count}}</span>
post{{group.posts.count|pluralize}}
</div>
</div>
</div>
</a>
{% empty %}
<p>You have not joined any groups yet! <p>
{% endfor %}
</div>
