This is my attempt to explain the problem and collect everyone else's responses into a single list. Thanks to everyone for giving me shoulders to stand on!
I believe this happens because Django REST Framework wants to render a template (<code>rest_framework/api.html</code>), but the template can't be found. It seems there are two approaches to fix this:
<h1>Approach 1: Make templates work</h1>
Ensure REST Framework is included in <a href="https://docs.djangoproject.com/en/3.0/ref/settings/#std:setting-INSTALLED_APPS" rel="noreferrer"><code>INSTALLED_APPS</code></a> in <code>settings.py</code>:
<pre class="lang-py prettyprint-override"><code>INSTALLED_APPS = [
 ...
 'rest_framework',
 ...
]
</code></pre>
And ensure <a href="https://docs.djangoproject.com/en/3.0/ref/settings/#std:setting-TEMPLATES-APP_DIRS" rel="noreferrer"><code>APP_DIRS</code></a> is <code>True</code> in your template configuration (it defaults to <code>False</code> if not specified). This allows Django to look for templates in installed applications. Here's a minimal configuration that seems to work, though you might have more config here:
<pre class="lang-py prettyprint-override"><code>TEMPLATES = [
 {
 'BACKEND': 'django.template.backends.django.DjangoTemplates',
 'APP_DIRS': True,
 },
]
</code></pre>
<h1>Approach 2: Return a JSON response</h1>
If you tell REST Framework to render a JSON response then it doesn't need to use a template so you don't need to change the <code>APP_DIRS</code> settings as mentioned above. It also seems like you might not even need to list rest_framework in <code>INSTALLED_APPS</code>, though it might be necessary to have it there for other reasons.
You can do this globally in settings.py:
<pre class="lang-py prettyprint-override"><code>REST_FRAMEWORK = {
 'DEFAULT_RENDERER_CLASSES': [
 'rest_framework.renderers.JSONRenderer',
 ]
}
</code></pre>
Or if you're using the <code>@api_view</code> decorator then you can specify JSONRenderer on each view:
<pre class="lang-py prettyprint-override"><code>@api_view(['GET'])
@renderer_classes([JSONRenderer])
def some_view(request):
 return Response({'status': 'yay'})
</code></pre>
See <a href="https://www.django-rest-framework.org/api-guide/renderers/" rel="noreferrer">the REST Framework renderers documentation</a> for details.

I hit this issue when upgrading from an old Django version to Django 2.0. My <code>settings.py</code> did not have a <code>TEMPLATE</code> directive at all, so I snagged the following from a new <code>django-admin.py startproject ...</code> run:

<pre><code>TEMPLATES = [
 {
 'BACKEND': 'django.template.backends.django.DjangoTemplates',
 'DIRS': [],
 'APP_DIRS': True,
 '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',
 ],
 },
 },
]
</code></pre>

Add that to your <code>settings.py</code> if you don't have <code>TEMPLATES</code> directive in your <code>settings.py</code>. Worked for me.

when I check as a API, I get response with 200 ok status. This shows Im unable to get my html page

How should I get my html depending on request
