Can't run Django template engine - Django

Question

from django import template

t = template.Template("My name is {{ name }}.")
c = template.Context({'name' : 'Yasmika'})
print(t.render(t))

I'm learning the basics of Python Django. When I'm trying to run Django template, Python interpreter gives me this error. How can I fix this?

django.core.exceptions.ImproperlyConfigured: Requested setting TEMPLATES, but settings are not configured. You must either define the environment variable DJANGO_SETTINGS_MODULE or call settings.configure() before accessing settings.

That's not a useful mentality when writing code... Django isn't really meant to be used outside of a Django project. You can configure it to work from within a single `.py` file, but it takes some effort. — Blender, May 19 '17 at 05:31

I think you are trying

print(t.render(c))

Do python manage.py shell

In [74]: from django import template

In [75]: t = template.Template("My name is {{ name }}.")

In [76]: c = template.Context({'name' : 'Yasmika'})

In [77]: print(t.render(c))
My name is Yasmika.

Exactly, running `t.render(t)` makes no sense. +1 – cezar May 19 '17 at 06:22

Django isn't really meant to be used outside of a Django project (or something that looks like one). You can start a Django project by following the "Writing your first Django app" tutorial. Once you have a project setup, launch a shell by running:

$ python manage.py shell

This loads a Python shell with Django fully configured to use your settings.

It looks like you don't have your DJANGO_SETTINGS_MODULE setting defined in your environment.

Have a look here for the documentation related to the settings module -> https://docs.djangoproject.com/en/1.8/topics/settings/

Your can set it like this

export DJANGO_SETTINGS_MODULE=<yoursite>.settings

When you use Django, you have to tell it which settings you’re using. Do this by using an environment variable, DJANGO_SETTINGS_MODULE.

The value of DJANGO_SETTINGS_MODULE should be in Python path syntax, e.g. mysite.settings. Note that the settings module should be on the Python import search path.
