Using my custom templatetag for user permission gives me the error “no permission matches the given query.” where could I be going wrong here?

Here is my custom permission template tag(templatetags/init.py, user_perm.py):

from django import template
from django.contrib.auth.models import Permission
from django.shortcuts import get_object_or_404

register = template.Library()

@register.filter(name='has_perm')
def has_perm(user, perm_name):
    perm = get_object_or_404(Permission, name=perm_name)
    perms = perm.permissions.all()
    if perms:
        return perm in user.get_all_permissions()
    else:
        return ""

and here is a my template usage:

.

..
{% load  user_perm %}
...
          {% if request.user|has_perm:"staff" %}
                    <h6><span id="sent">No teams are defined, but you can</span>
                        <a
                            class="btn btn-default btn-mini" id="action_text"
                            href='{% url "committee-create" project.slug %}'> create one
                        </a>
                   </h6>
          {% endif %}

What I have tried:

Calling permissions in templates such as superuser not working, calling all user permissions in templatetag to filter the parsed permission in template.
