/custom-template-tags/]
It seems the TEMPLATES settings must include a new element in order to
properly register custom filters:
{{{
['OPTIONS']['libraries']
}}}
My structure is:
{{{
profile/
- __init__.py
- models.py
- urls.py
- views.py
- templetags/
- - __init__.py
- - filters.py
templates/
- profile/
- - overview.html
}}}
Excerpt of filters.py:
{{{
from profile.models import Profile
from django import template
register = template.Library()
@register.filter(name='she_he')
def she_he(profile: Profile, cap=False):
pronoun = 'she' if profile.gender == 'F' else 'he'
return pronoun.capitalize() if cap else pronoun
}}}
Excerpt of overview.html:
{{{
{% extends "base.html" %}
{% load filters %}
{% block content %}
<p>{{ profile|her_his }} current role
}}}
My app is declared in INSTALLED_APPS, and it worked before I added the
filter and the load in the template.
Yet I got this error:
{{{
'filters' is not a registered tag library. Must be one of:
[...]
}}}
To make it work, I had to add the 'libraries' item in TEMPLATES, in
settings.py:
{{{
TEMPLATES = [
{
'BACKEND': 'django.template.backends.django.DjangoTemplates',
'DIRS': [os.path.join(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',
],
'libraries': {
'filters': 'profile.templetags.filters'
}
},
},
]
}}}
I don't see that on that page, which makes it very confusing.
