Fehler in index.html von django-admin mit django-admin-notifications

Question

Ich verwende django, um ein neues Admin-Panel zu machen, und ich verwende auch django-admin-notifications, um Benachrichtigungen in meinem Admin-Panel anzuzeigen. Ich weiß nicht, warum es nicht funktioniert.

Hier ist meine models.py

from __future__ import unicode_literals 

from django.db import models 

class MyAlbum(models.Model): 
    title = models.CharField(max_length=30) 
    photos = models.IntegerField() 
    def __unicode__(self): 
     return self.title 


class Person(models.Model): 
    first_name = models.CharField(max_length=30) 
    last_name = models.CharField(max_length=30) 
    def __unicode__(self): 
     return self.first_name 


class Musician(models.Model): 
    first_name = models.CharField(max_length=50) 
    last_name = models.CharField(max_length=50) 
    instrument = models.CharField(max_length=100) 
    def __unicode__(self): 
     return self.first_name 

mein admin.py

from django.contrib import admin 
from django.contrib.admin import AdminSite 
from .models import Person,MyAlbum,Musician 

from django.contrib import admin 




class MyAdminSite(AdminSite): 
    site_header = 'Wedding Administration' 

site_admin = MyAdminSite(name='weddingadmin') 

admin.site.register(Person) 
admin.site.register(MyAlbum) 
admin.site.register(Musician) 


site_admin.register(Person) 
site_admin.register(MyAlbum) 

mein notifications.py

import admin_notifications 
from models import Person 
def notification(): 
    broken_links = Person.objects.filter(status=False).count() 
    if broken_links: 
     return "You have %s broken link%s.<br>You can view or fix them using the <a href='/admin/linkcheck/'>Link Manager</a>." % (broken_links, "s" if broken_links>1 else "") 
    else: 
     return '' 

admin_notifications.register(notification) 

Ich habe auch in index.html Änderungen der Verwaltungsseite

{% load notification_tag %} 

{% extends "admin/base_site.html" %} 
{% load i18n static %} 

{% block extrastyle %}{{ block.super }}<link rel="stylesheet" type="text/css" href="{% static "admin/css/dashboard.css" %}" />{% endblock %}

      {% endfor %} 
      </ul> 
      {% endif %} 
    </div> 
</div> 
{% endblock %} 

Bitte sagen Sie mir, was ich tue falsch.Die index.html ist die eigentliche index.html der Admin-Vorlage

EDIT 1:

TemplateSyntaxError at /admin/ 

'notification_tag' is not a registered tag library. Must be one of: 
admin_list 
admin_modify 
admin_static 
admin_urls 
cache 
i18n 
l10n 
log 
static 
staticfiles 
tz 

Answer 1

Ich war die Installation django-admin-Benachrichtigungen über pip aber ich habe festgestellt, dass nur init.py in den site-paketen installiert war, also habe ich das repository geklont, also rate ich nicht django-admin-notifications via pip, obwohl es ein paket gibt, aber nur die init.py-datei war installiert
