Django Custom Template Tags Issue

Based on your error message and code, there are a few key issues that need to be addressed to get your custom template tags working properly.

File Structure Requirements

Django has specific requirements for custom template tags:

1. Your template tags file must be inside a templatetags package within your app
2. The templatetags directory must contain an __init__.py file to make it a proper Python package

Your file structure should look like this:

base/
    __init__.py
    apps.py
    models.py
    templatetags/
        __init__.py
        my_templates.py  # Your template tags file

Template Tag File Naming

The name of your template tag file (my_templates.py) must match the name you use when loading it in your template. Based on your error, you're trying to load my_templates, so your file should be named my_templates.py.

Loading the Template Tags

In your template, you need to load your custom template tags before using them:

HTMLCopied
{% load my_templates %}

{{ some_value|to_str }}

Additional Checks

1. Make sure your Django app is properly installed and included in INSTALLED_APPS
2. After adding the template tags, restart your Django development server
3. If you're using template caching, you might need to clear the cache

If you've followed all these steps and still encounter issues, try running python manage.py check to see if Django detects any problems with your application setup.
