Django : TemplateDoesNotExist at /.../

You have forgotten the first argument request when you call render.

return render(request, 'index.html', context)

You can have multiple template directories, e.g. src/template and pages/template. If you want to have a src/template directory, then you need to include it in your DIRS option`.

    'DIRS': [os.path.join(BASE_DIR, 'templates')],

You don't need pages/templates in the DIRS directory -- templates in that directory will be found by the app loader because you have APP_DIRS set to True, and pages is in your INSTALLED_APPS setting.

You probably forgot to add your app in Installed_Apps setting.

INSTALLED_APPS = [

...

'your_app'  

]

You have wrong route of your templates. By default django have the folder "template" for html files, try create folder called template inside your app folder and inside them the file index.html
