Wow.
Thanks for this tip - it was the key to solving my problem.
Here is how I solved it (or worked around it), if it is useful to anyone else...
The first thing that is different about my app is that it is just a plain
command line utility that takes input and generates a suite of files using
templates, not a web application. That means that I didn't put my code in a
package or want a settings file.
By using the in-place config code I was able to avoid a django_settings.py file:
> import django.conf
> django.conf.settings.configure(
> TEMPLATE_DIRS =(this_dir),
> )
This worked up until I wanted my own filter.
Adding it under a templatetags dir/package didn't help.
The cause of the problem was that my code wasn't in a package per sae.
Workaround: make it look like my code is in a package.
(I could have actually *put* it in a package, but I didn't want to.)
So, code is under something like: C:\dev\foo\codeGenerator.py
then:
> from django.template import Context, Template, Library
>
> this_full_dir=os.path.abspath(os.path.dirname(sys.argv[0]))

> sys.path.append(this_container_dir)
>
> import django.conf
> django.conf.settings.configure(
> TEMPLATE_DIRS =(this_full_dir), # my templates are in the same dir
> INSTALLED_APPS = (this_package_name),
> )
this will automatically make sure that the dir *containing* my code is in the
path and that my pseudo-package is the name of my installed app.
I think a better long term solution is something like:
Template.add_templatetags_file('filename.py')
But in the absence of that, the above magic works :)
Thanks James + team
