We saw how class-based views work in Flask using the concept of pluggable views in the Class-based views recipe in Chapter 4, Working with Views. We will now see how we can use the same concept to create views, which will provide a REST interface to our application.
We have to simply modify our views for product handling to extend the MethodView class:
from flask.views import MethodView
class ProductView(MethodView):
def get(self, id=None, page=1):
if not id:
products = Product.query.paginate(page, 10).items
res = {}
for product in products:
res[product.id] = {
'name': product.name,
'price': product.price,
'category': product.category.name
}
else:
product = Product.query.filter_by(id=id...
