    <p>It is good practice to have mobile clients periodically renew their authentication token. This of course is up to the server to enforce.</p> <p>The default TokenAuthentication class does not support this, however you can extend it to achieve this functionality.</p> <p>For example: </p> <pre><code>from rest_framework.authentication import TokenAuthentication, get_authorization_header from rest_framework.exceptions import AuthenticationFailed class ExpiringTokenAuthentication(TokenAuthentication): def authenticate_credentials(self, key): try: token = self.model.objects.get(key=key) except self.model.DoesNotExist: raise exceptions.AuthenticationFailed('Invalid token') if not token.user.is_active: raise exceptions.AuthenticationFailed('User inactive or deleted') # This is required for the time comparison utc_now = datetime.utcnow() utc_now = utc_now.replace(tzinfo=pytz.utc) if token.created &lt; utc_now - timedelta(hours=24): raise exceptions.AuthenticationFailed('Token has expired') return token.user, token </code></pre> <p>It is also required to override the default rest framework login view, so that the token is refreshed whenever a login is done:</p> <pre><code>class ObtainExpiringAuthToken(ObtainAuthToken): def post(self, request): serializer = self.serializer_class(data=request.data) if serializer.is_valid(): token, created = Token.objects.get_or_create(user=serializer.validated_data['user']) if not created: # update the created time of the token to keep it valid token.created = datetime.datetime.utcnow() token.save() return Response({'token': token.key}) return Response(serializer.errors, status=status.HTTP_400_BAD_REQUEST) obtain_expiring_auth_token = ObtainExpiringAuthToken.as_view() </code></pre> <p>And don't forget to modify the urls:</p> <pre><code>urlpatterns += patterns( '', url(r'^users/login/?$', '&lt;path_to_file&gt;.obtain_expiring_auth_token'), ) </code></pre>

    2. COWouldn't you want to create a new token in ObtainExpiringAuthToken if it's expired though, rather than just update the timestamp for the old one?

    3. COCreating a new token makes sense. You could also regenerate the value of the existing tokens key and then you would not have to delete the old token.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
