How to check (in template) if user belongs to a group

• You need a custom template tag:

from django import template

register = template.Library() 

@register.filter(name='has_group') 
def has_group(user, group_name):
    return user.groups.filter(name=group_name).exists() 

• In your template:

{% if request.user|has_group:"mygroup" %} 
    <p>User belongs to my group 
{% else %}
    <p>User doesn't belong to mygroup</p>
{% endif %}

Django session variable in JavaScript

In Views.py Add:

class SessionVarView(TemplateView):

    permission_classes = [permissions.IsAuthenticated]    

    @csrf_exempt

    def get(self, request, *args, **kwargs):

        print(request)

        return HttpResponse(request.session[kwargs['key']])

In Urls.py Add:

    re_path(r'^session/(?P<key>[^/]+)$', views.SessionVarView.as_view(), name='session-var'),

Then you could get it from JS via http://127.0.0.1/session/key_name_here or something similar.
