[Fixed]-Django & the "TemplateDoesNotExist" error

One of the solution to this problem is you should add apps to in settings.py. I assume you have an application named such as invoice then solution to this is

INSTALLED_APPS = [
'invoice.apps.InoviceConfig',
'django.contrib.admin',
'django.contrib.auth',
'django.contrib.contenttypes',
'django.contrib.sessions',
'django.contrib.messages',
'django.contrib.staticfiles',
]

If anyone is trying this with Django 1.7 and Python 3 or higher, I did this:

TEMPLATE_DIRS = [os.path.join(BASE_DIR, 'mysite_dir/templates')]

where myfile_dir can be any dir under mysite. File structure would be something like this:

manage.py
mysite/  
  mysite/  
  mysite_dir/  
  templates/  
    ____init__.py  
    models.py  
    #...
  another_app/  

This answer may seem repetitive but I know I always like to see things from a more recent date… so hope this helps

I struggled with a similar issue for a good several hours and found that I could get the template to load if I put it in a /templates subdirectory within the app using the template. You don’t even need to set TEMPLATE_DIRS in settings.py, the file is found automatically. Unfortunately the TemplateDoesNotExist exception is not very descriptive and in some cases literally wrong. If you see in the Template-loader postmortem something similar to the following:

Django tried loading these templates, in this order:
Using loader django.template.loaders.filesystem.Loader:
/Users/me/mysite/myapp/index.html

And the file path looks correct for the template you’re trying to load, it’s likely that the file exists but it’s not accessible. Try moving it to a /templates subdirectory of the app.

If you follow Django’s documentation, they recommend namespacing your templates, where under templates, you have /yourapp/ again before the templates. See here.

So your structure might look like:

Project Folder
--Project
--yourapp
  --templates
    --yourapp
      --layout.html

But what they don’t make clear is that any hardcoded references to those templates (for example, the render function), need to also prepend your app name to those as well! I thought Django was doing a recursive search for us, but I gave it too much credit. You need to point to the exact link.

e.g.

return render(request, "login.html")

goes to

return render(request, "orders/login.html")

You’ll likely need this too in any extends statements or where you use static to link to files.

For me {% include 'some.html' %} was throwing this error.
Make sure to include the leading ./ like:
{% include './some.html' %}

Just paste the path of your templates directory from your source root in your project settings dirs variable. It should look something like this

    'DIRS': [
        'templates'
    ],

just set DEBUG to false in your Django settings file
