Whats wrong with this code piece?

Why bummer is coming?

api.py
from flask import Flask

from resources.ingredients import ingredient_api
from resources.recipes import recipe_api

import models


app = Flask(__name__)
app.register_blueprint(ingredient_api)
app.register_blueprint(recipe_api)


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

import models


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


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


ingredient_api = Blueprint('resources.ingredients', __name__)
api = Api(ingredient_api)
api.add_resource(
    IngredientList,
    '/api/v1/ingredients',
    endpoint= 'ingredients'
)

api.add_resource(
    Ingredient,
    '/api/v1/ingredients/<int:id>',
    endpoint='ingredients'
)
resources/recipes.py
from flask.ext.restful import Resource, Api
from flask import Blueprint

import models


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


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


recipelist_api=Blueprint('resources.recipes', __name__)
api = Api(recipe_api)
api.add_resource(
    RecipeList,
    '/api/v1/recipes',
    endpoint='recipes'
)


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

On Task 2, you have two typos in your Blueprint statements:

ingredient_api = Blueprint('resources.ingredients', __name__) # ingredients_api not ingredient_api
recipelist_api = Blueprint('resources.recipes', __name__) # recipes_api not recipelist_api

Post back if you're having more issues. Good Luck!!!

Continuing on....

ingredients.py
api = Api(ingredient_api) # 'ingredients' should be plural
api.add_resource(
    IngredientList,
    '/api/v1/ingredients',  # 'ingredient' should be single not plural
    endpoint= 'ingredients' # endpoint names should be unique. This matches the resource below
)

api.add_resource(
    Ingredient,
    '/api/v1/ingredients/<int:id>',
    endpoint='ingredients'# endpoint names should be unique. This matches the resource above
)
recipes.py
recipelist_api=Blueprint('resources.recipes', __name__)  # should be 'recipes_api' not 'recipelist_api'
api = Api(recipe_api) # should be 'recipes_api' not 'recipe_api'
api.add_resource(
    RecipeList,
    '/api/v1/recipes',  # 'recipe' should be single not plural
    endpoint='recipes'
)


api.add_resource(
    Recipe,
    '/api/v1/recipes/<int:id>',
    endpoint='recipe'  # endpoints pass because they are unique, but probably should be reversed to make more sense with the code.
)

Good Luck!!!
