Python Flask REST API Resourceful Blueprints Register API

Help I'm stuck! I can't figure out where I made a mistake.

I don't understand what to do next.

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(ingredients_api)
app.register_blueprint(recipes_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'

ingredients_api = Blueprint('resources.ingredients',__name__)
api = Api(ingredients_api)
api.add_resource(
    IngredientList,
    '/api/v1/ingredients',  
    endpoint='ingredients'
)
api.add_resource(
    Ingredients,
    '/api/v1/ingredients/<int:id>',  
    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 'recipes'

recipes_api = Blueprint('resources.recipes',__name__)   
api = Api(recipes_api)
api.add_resource(
    RecipeList,
    '/api/v1/recipes',   
)
api.add_resource(
    Recipe,
    '/api/v1/recipes/<int:id>',   
)

Question is: "Alright, one last step! You need to import the blueprints into app.py and register them both with app."

Hi Ashley Trice looking over the posted code and pulling it down locally I see the following errors

which makes me thing that might be one of the issues. The other issue that I saw was in the api file code was where we are trying to import recipe_api but that should be recipes_api with an s which is what I think is missing and the same looks to be true for the ingredients_api as well.
