[Django]-TemplateDoesNotExist – Django Error

Please note that the DRF attempts to return data in the same format that was requested. From your browser, this is most likely HTML. To specify an alternative response, use the ?format= parameter. For example: ?format=json.

The TemplateDoesNotExist error occurs most commonly when you are visiting an API endpoint in your browser and you do not have the rest_framework included in your list of installed apps, as described by other respondents.

If you do not have DRF included in your list of apps, but don’t want to use the HTML Admin DRF page, try using an alternative format to ‘side-step’ this error message.

More info from the docs here: http://www.django-rest-framework.org/topics/browsable-api/#formats

For me, rest_framework/api.html was actually missing on the filesystem due to a corrupt installation or some other unknown reason. Reinstalling djangorestframework fixed the problem:

$ pip install --upgrade djangorestframework

Not your case, but also possible reason is customized loaders for Django. For example, if you have in settings (since Django 1.8):

TEMPLATES = [
{
    ...
    'OPTIONS': {
        'context_processors': [
            'django.template.context_processors.debug',
            'django.template.context_processors.request',
            'django.contrib.auth.context_processors.auth',
            'django.contrib.messages.context_processors.messages'
        ],
        'loaders': [
            'django.template.loaders.filesystem.Loader',
        ],
        ...
    }
}]

Django will not try to look at applications folders with templates, because you should explicitly add django.template.loaders.app_directories.Loader into loaders for that.

Notice, that by default django.template.loaders.app_directories.Loader included into loaders.

I ran into the same error message. In my case, it was due to setting the backend to Jinja2. In my settings file:

TEMPLATES = [
{
    'BACKEND': 'django.template.backends.jinja2.Jinja2',
...

Changing this back to the default fixed the problem:

TEMPLATES = [
{
    'BACKEND': 'django.template.backends.django.DjangoTemplates',
...

Still not sure if there is a way to use the Jinja2 backend with rest_framework.

We can get the error even if we missed adding the ‘rest_framework’ in the installed apps.
So please check that too if you are facing the error.
