I am working through this Getting started with Django Rest Framework by Building a Simple Product Inventory Manager tutorial. At the end the tutorial, it says that I "should now be able to run your server and start playing with diffrent API endpoints". However, when I run the server, all I'm getting is a TemplateDoesNotExist error. At no point in the tutorial does it mention creating templates (and this is eventually going to connect to an Angular 2 frontend, as shown in this tutorial), so I'm confused at to whether this is an error in my code, or if the tutorial left a step out. I do not get any console errors when I run my code.
serializers.py
from .models import Product, Family, Location, Transaction
from rest_framework import serializers
class LocationSerializer(serializers.ModelSerializer):
class Meta:
model = Location
fields = ('reference', 'title', 'description')
class FamilySerializer(serializers.ModelSerializer):
class Meta:
model = Family
fields = ('reference', 'title', 'description', 'unit', 'minQuantity')
class ProductSerializer(serializers.HyperlinkedModelSerializer):
class Meta:
model = Product
fields = ('sku', 'barcode', 'title', 'description', 'location', 'family')
depth = 1
class TransactionSerializer(serializers.ModelSerializer):
product = ProductSerializer()
class Meta:
model = Transaction
fields = ('sku', 'barcode', 'product')

IF you need to see more of my code, please comment and I'll post it, but everything should be identical to the code given in the tutorial.

May be you forgot to add rest_framework
in the installed apps(settings.py).
INSTALLED_APPS = (
...
'rest_framework',
)
