如何正确地将模板标签添加到Django项目

Question

I am playing with django-gentelella and try to add custom template tags to the project.

According to the latest Django documentation, one should add a "templatetags" directory, at the same level as models.py, views.py, etc. Also, an init .py file should be placed in the directory.

I added my template tags into a file called "template_tags.py" and restarted the server. In my templates, I load the file using "{% load template_tags %}" at the top of the file.

Unfortunately, this does not work yet. According to the Django documentation, it is also required to add the template_filters to the INSTALLED APPS.

My problem is that I cannot figure out how to get the right path in dot notation. Can anyone point me in the right direction?

Answer 1

/profiles/templatetags/custom_tags.py

@register.filter(name='getLocalTimeDifference')
def getLocalTimeDifference(value):
    value = value.replace(..)
    return value

/profiles/templates/navbar.html

{% load custom_tags %}
...

<div class="notification-meta">
    <small class="timestamp">{{ notification.timesince | getLocalTimeDifference}} before </small>
</div>

PS __init_.py should also be added to templatetags directory
