1. Modify the recipe schema to include all attributes except for email. In schemas/recipe.py, modify only=['id', 'username'] to exclude=('email', ).

        author = fields.Nested(UserSchema, attribute='user', dump_only=True, exclude=('email', ))

2. Modify the get method in RecipeResource to serialize the recipe object into JSON format using the recipe schema:

           return recipe_schema.dump(recipe).data, HTTPStatus.OK
