'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)

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?
Django Solutions
Solution 1 - Django
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.
Solution 2 - Django
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.

Make sure you are not missing any of the following steps:
-
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
-
Restart the django server
Solution 4 - Django
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.
Solution 5 - Django
you have to manually stop the development server and start it again, so Django can identify the new template tags
Solution 6 - Django
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.
Solution 7 - Django
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.
Solution 8 - Django
Restart the django server. It worked for me after setting the templatetag folder within the app and template_name.py in the templatetag folder.
Solution 9 - Django
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
Solution 10 - Django
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.
Solution 11 - Django
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
Solution 12 - Django
put my_templatetag.py inside app_name/templatetags then create init.py inside app_name/templatetags .. Then open terminal in project folder give command python manage.py shell >>from app_name.templatetags import my_templatetag
Solution 13 - Django
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.
Solution 14 - Django
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
Solution 15 - Django
at first stop the server.remove/cut the code from templatetags/tag.py and rewrite/paste it.then run the server.it worked for me
