Django 1.10.1 'my_templatetag' is not a registered tag library. Must be one of:

I want a menu thats custom depending which group you are member of. Im using Django 1.10.1, allauth and so on. When im trying to make my templatetag it fails and it says:¨

TemplateSyntaxError at /
'my_templatetag' is not a registered tag library. Must be one of:
account
account_tags
admin_list
admin_modify
admin_static
admin_urls
cache
i18n
l10n
log
socialaccount
socialaccount_tags
static
staticfiles
tz

'my_templatetag.py' looks like this:

from django import template
from 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 group in user.groups.all()

and tha error comes in my .html file which say,

{%  load my_templatetag %}

I have tried to restart the server like millions of times, also i tried to change all the names, and the app is a part of INSTALLED_APPS in settings.py. What am I doing wrong?

I know this is old, but in your case you should try {% load has_group from my_templatetag %}

This Solved My Problem:

  1. make sure templatetags folder exsist in main django project
  2. use this line in INSTALLED_APPS in project settings.py:
INSTALLED_APPS = [
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',
     ...
  
    'my_app.apps.AppConfig',
    
]

For me, I had to register my customer Filter as this since my templatetags are outside of any app

TEMPLATES = [
    {
        'BACKEND': 'django.template.backends.django.DjangoTemplates',
        'DIRS': [BASE_DIR, 'templates'],
        'APP_DIRS': True,
        'OPTIONS': {
            'context_processors': [
                'django.template.context_processors.debug',
                'django.template.context_processors.request',
                'django.contrib.auth.context_processors.auth',
                'django.contrib.messages.context_processors.messages',
                'django.template.context_processors.media',
            ],
            # ! New Line
            'libraries':{
                'customFilter': 'templatetags.customFilter',
            }
        },
    },
]

From Django 1.9, you can load those new tags/filters in settings like this:

TEMPLATES = [
{
    'BACKEND': 'django.template.backends.django.DjangoTemplates',
    'DIRS': [],
    'APP_DIRS': True,
    'OPTIONS': {
        'context_processors': [
            'django.template.context_processors.debug',
            'django.template.context_processors.request',
            'django.contrib.auth.context_processors.auth',
            'django.contrib.messages.context_processors.messages',
            'app.apptemplates.load_setting',
            
        ],
                
        'libraries':{
            'my_templatetag': 'app.templatetags.my_templatetag',
            
            }
    },
},

]

If you have templatetag dir in your project dir (not in an app dir), then above method is recommended.

Example-
enter image description here

Quoting: https://docs.djangoproject.com/en/3.2/howto/custom-template-tags/#:~:text=It%20also%20enables%20you%20to%20register%20tags%20without%20installing%20an%20application.

The templatetags folder must have a __init__.py file in order to be a regular python package

Ensure that you also created the templatetags.py file next to the __init__.py file

I solved this by adding a templatestag folder in the root with a filter.py file defining my filters, then I adjusted my settings.py.

Please check my complete answer regarding this issue in this similar thread

you have to manually stop the development server and start it again, so Django can identify the new template tags

In case it helps someone, the issue in my case was that I was using quotes when trying to load the tag(s)

{%  load 'my_templatetag' %}  <!-- incorrect -->

instead of

{%  load my_templatetag %}  <!-- correct -->

Note: extends needs quotes around the filename but not load

In my case the problem was, I was using {% load filter_method_name %}

I had to change to {% load filename %}

I then had to restart the server.

I know this is a bit old, but I ran into the same problem today. I found the solution in the docs: https://docs.djangoproject.com/en/dev/howto/custom-template-tags/

The app should contain a templatetags directory, at the same level as models.py, views.py, etc. If this doesn’t already exist, create it - don’t forget the __init__.py file to ensure the directory is treated as a Python package.

Simply copying the __init__.py from another location into the new templatetag's directory sorted it out.

Where is 'my_templatetag.py' stored? It should be stored in a directory called 'templatetags' which is within the app.

Please see: https://docs.djangoproject.com/en/dev/howto/custom-template-tags/ if that isn't the case.

I am using Django 1.11, and I was having the same problem. Some of the answers here are right, but some things may be missing. Here is what I did:

Quoting a previous user:

Create a folder called "templatetags" at the same level as models.py and views.py in your application folder

Your application must be in the INSTALLED_APPS in settings.py

The templatetags folder must have init.py

But, before you re-start the Django server, add this to the file that contains the tags:

from django import template
register = template.Library()

Then you can re-start the server.

you just cut/remove your code which written inside the (example templatetags/home.py) from home.py you remove your code and restart your server and again paste your code in home.py it will work.

Make sure you are not missing any of the following steps:

  1. Create a folder called "templatetags" at the same level as models.py and views.py in your application folder

  2. Your application must be in the INSTALLED_APPS in settings.py

  3. The templatetags folder must have __init__.py

  4. Restart the django server

Restart the django server. It worked for me after setting the templatetag folder within the app and template_name.py in the templatetag folder.

Besides putting my_templatetag.py inside app_name/templatetags, make sure you restart the Django development server (or ensure it restarted itself) every time you modify template tags. If the server does not restart, Django won't register the tags.
