Comment:
Hello Erik, thank you for the sample Django project; it's been helpful.
Now that I understand your issue, after reviewing the documentation
thoroughly, I believe the problem stems from a potential misunderstanding
of how the template name should be defined. You are using pathlib to
define the template name, suggesting that the value could be a Path
instance. However, the Django template system expects the template name to
be a string identifier.
If you refer to these sections in the documentation:
* [https://docs.djangoproject.com/en/dev/topics/templates/#module-
django.template.loader django.template.loader] "This function loads the
template with the given name and returns a Template object."
*
[https://docs.djangoproject.com/en/dev/topics/templates/#django.template.loader.render_to_string
render_to_string] "template_name: The name of the template to load and
render"
The `template_name` should be a string, not a `Path` instance. It serves
as an identifier for the template rather than a direct path in the
filesystem. Each template loader then performs the necessary
transformations or lookups using this identifier to find the requested
template, utilizing whichever storage mechanism they are configured with
(e.g., in-memory cache, filesystem, network-based storage, etc).
I'll be closing this ticket accordingly, if you have further questions
about this topic, please reach out to the Django community in the
[https://forum.djangoproject.com/ Django Forum].
