Great job completing Task List Angela! Your code looks clean and easily readable. I want to point out the good variable naming and your code is DRY. Great use of helper methods in your models! Excellent work using blue prints & creating RESTful CRUD routes for each model.

Great job creating this reusable helper function`

Nice approach creating this relationship to your Goal model. Why not use lazy here?

👍🏾 These imports help a great deal when it comes to our request & response cycle

Nice job creating this reusable function & keeping your code DRY. Nice approach to handling an invalid model 😁

Great job using db.session.<method-name>. Session gives us access to the follow:
dbis our app’s instance of SQLAlchemy.sessionrepresents our active database connection.- By referencing
db.sessionwe can use SQLAlchemy’s methods to perform tasks like:- committing a change to a model
- storing a new record of a model
- deleting a record.
- By referencing
db.session.add()you are able to use the SQLAlchemy method to store a new record of the task model

Great job! We need to pass our instance of our app & the instance of our SQLALchemy db to connect the db and migrate to our Flask app

Usually a resource creation relates to a 201 response code 👍🏾
