Example inclusion tag

Hi,
The plans are to use classytags on the website at work and I'm going through the documentation and running some experimental code as I go. This is being run on with classtags 0.8.0, python 3.5.2, and django 1.10.3.
I've written some templates and using classy tags, written an inclusion tag that works as expected. I then add a block tag, called 'Jimblock' and the browser cannot find it. In the browser, I get the error message in the included file, 'browser_error_msg.txt
The last part of the error message is:
Exception Type: TemplateSyntaxError at /Ttags/classHello/
Exception Value: Invalid block tag on line 20: 'Jimblock'. Did you forget to register or load this tag?
I would expect the browser to find 'Jimblock' because it found 'Jinclusion' before I add 'Jimblock'. Both are defined in the same file, 'customClassTemplateTags.py', which is attached. The template, 'classTemplateTags.html' which references 'Jinclusion' and 'Jimblock' is also attached.
Directory structure is:
.../testDjangoProject
|
-------------> utilTemplateTags
|
--------------> templates
| |
| --------------> utilTemplateTags (contains: classTemplateTags.html)
|
---------------> templatetags (contains: customClassTemplateTags.py)
My settings.py file has the following entry:
TEMPLATES = [
{
'BACKEND': 'django.template.backends.django.DjangoTemplates',
'DIRS': [
os.path.join(BASE_DIR, 'templates'), ### This is the base directory for templates
os.path.join(BASE_DIR,"polls/templates/polls"),
os.path.join(BASE_DIR,"utilTemplateTags/templates"),
os.path.join(BASE_DIR,"utilTemplateTags/templates/utilTemplateTags"),
],
'APP_DIRS': True,
....
}
I believe this entry for TEMPLATES is correct. Like I said previously, 'Jinclusion' is being found, so I expect 'Jimblock' to also be found.
Can anyone help with suggestions?
