Great job completing Task List Elaine! 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.

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

Great job creating this reusable helper function

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

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

Nice work with this test completion! This assertion is a great way to validate functionality is working as expected

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