I found this to be somewhat challenging too when I tried the code out a couple of years back.

I didn't test your code, but I can see possible issues when you declare the ingredients api.add_resource() URL for IngredientList and the recipe resource Api() class declaration. A slash should lead the URL.

The name parameter might be an issue on recipes api

#api = Api(recipes_api, __name__) # the __name__ parameter should be omitted.
api = Api(recipes_api) # this should work

Also the api.add_resource RecipeList might be a problem, you don't have a leading slash.

See below.

partial code for recipes.py

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

partial code for ingredients.py

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/<int:obj_id>',
    endpoint = 'ingredient'
)
