Creating a class-based REST interface

We saw how class-based views work in Flask, using the concept of pluggable views, in the Writing class-based views recipe in Chapter 4, Working with Views. In this recipe, we will now see how we can use the same to create views, which will provide a REST interface to our application.

Getting ready

Let’s take a simple view that will handle the REST-style calls to our Product model.

How to do it...

We simply have to modify our views for product handling to extend the MethodView class in views.py:

import json
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
      ...
