Python Flask REST API Resourceful Blueprints Register API

Create a new variable named api in each of the resources that's an Api instance for the Blueprint.

I followed the video completely, but I'm probably missing something simple like a spelling error. The one thing I'm not entirely clear on is the part about [PLURAL RESOURCE] "/api/v1/recipes" or "api/v1/<int:id>". I tried it both ways and Its doesn't pass regardless

api.py
from flask import Flask

from resources.ingredients import ingredients_api
from resources.recipes import recipes_api

app = Flask(__name__)
app.register_blueprint(recipes_api)
app.register_blueprint(ingredients_api)


if __name__ == '__main__':
    app.run()
resources/ingredients.py
from flask import Blueprint
from flask.ext.restful import Resource, Api

import models


class IngredientList(Resource):
    def get(self):
        return 'IngredientList'


class Ingredient(Resource):
    def get(self, id):
        return 'Ingredient'

ingredients_api=Blueprint('resources.ingredients',__name__)
api=Api(ingredients_api)
api.add_resource(
    IngredientList,
    '/api/v1/ingredients',
    endpoint='ingredients'
    )
api.add_resource(
    Ingredient,
    '/api/v1/ingredients',
    endpoint='ingredient'
    )
resources/recipes.py
from flask import Blueprint
from flask.ext.restful import Resource, Api

import models


class RecipeList(Resource):
    def get(self):
        return 'RecipeList'


class Recipe(Resource):
    def get(self, id):
        return 'Recipe'

recipes_api=Blueprint('resources.recipes', __name__)
api=Api(recipes_api)
api.add_resource(
    RecipeList,
    '/api/v1/recipes',
    endpoint='recipes'
    )
api.add_resuorce(
    Recipe,
    '/api/v1/recipes',
    endpoint='recipe'
    )

Hi Chris,

You are right, you do have a spelling error in the last part of recipes.py (api.add_resuorce), however there are a couple more things you will need to change.

The Plural Resource part is basically asking you to have the plural form of the resource in the url of both of your resources.

The id parameter in the singular resource (Recipe/Ingredient), would be added on to the url in order to identify a specific recipe or ingredient. But they would still be within the plural resource.

So for recipes.py:

api.add_resource(
    RecipeList,
    '/api/v1/recipes',
    endpoint='recipes'
    )

api.add_resource(
    Recipe,
    '/api/v1/recipes/<int:id>',
    endpoint='recipe'
    )

And the same would apply for ingredients.py.

Hope this makes sense.
