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

You need custom template tag:

from django import templateregister = 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 %}

Docs: https://docs.djangoproject.com/en/dev/howto/custom-template-tags/

In your app create a folder 'templatetags'. In this folder create two files:

__init__.py

auth_extras.py

from django import templatefrom django.contrib.auth.models import Group register = template.Library()@register.filter(name='has_group')def has_group(user, group_name):     group = Group.objects.get(name=group_name)     return True if group in user.groups.all() else False

It should look like this now:

app/    __init__.py    models.py    templatetags/        __init__.py        auth_extras.py    views.py

After adding the templatetags module, you will need to restart your server before you can use the tags or filters in templates.

In your base.html (template) use the following:

{% load auth_extras %}

and to check if the user is in group "moderator":

{% if request.user|has_group:"moderator" %}     <p>moderator</p> {% endif %}

I'd say that the best way is:

yourapp/templatetags/templatetagname.py

from django import templateregister = template.Library()@register.filter(name='has_group')def has_group(user, group_name):    return user.groups.filter(name=group_name).exists()

yourapp/templates/yourapp/yourtemplate.html:

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

EDIT: added line with template tag loading as was advised in comments.

EDIT2: fixed minor typo.
