Jinja2 throwing templatedoesnotexist error in Django project - django

Question

I'm trying to use jinja2 in my Django project (ver 1.10). After setting it up, once I try to run the project, I get TemplateDoesNotExist at /base/index.html and
Template-loader postmortem
Django tried loading these templates, in this order:
Using engine jinja2:
This engine did not provide a list of tried templates.
In templates folder, I have a base directory where index.html is placed. Moreover, if I use Django's template engine, this same folder structure works perfectly. How can I fix this issue?
My config is as follows:
In settings.py (note that I've deliberately excluded the Django template fallback):
TEMPLATES = [
{
'BACKEND': 'django.template.backends.jinja2.Jinja2',
'DIRS': [os.path.join(BASE_DIR, 'templates')],
'APP_DIRS': True,
'OPTIONS': {'environment': 'uberfordoc.jinja2.environment',
},
},
]
I also have a file called jinja2.py kept in the project folder:
from __future__ import absolute_import
from django.contrib.staticfiles.storage import staticfiles_storage
from django.core.urlresolvers import reverse
from jinja2 import Environment
def environment(**options):
env = Environment(**options)
env.globals.update({
'static': staticfiles_storage.url,
'url': reverse,
})
return env

Answer 1

This was my BASE_DIR and MAIN_DIR in settings.py
BASE_DIR = os.path.dirname(os.path.abspath(__file__))
MAIN_DIR = os.path.dirname(os.path.dirname(__file__))
and my jinja2 templates were at the path
/Users/username/Desktop/uberfordoc/templates/jinja2
changed
'DIRS': [os.path.join(BASE_DIR, 'templates')],
to
'DIRS': [os.path.join(MAIN_DIR, 'templates/jinja2')],
and it worked. Got the hint thanks to #Timbadu by printing
print os.path.join(BASE_DIR, 'templates')
