I created it thinking I could add all the database querying functions and make the code dry, but sadly, I did not have enough time.

In Learn and in the livecode for Flasky, we name blueprints for each model bp. In goal_routes.py I can deduce that bp is the blueprint for Goal given the name of the file.
If we have multiple route files that each have a blueprint named bp, we can account for name collisions when importing them into app/__init__.py by using aliases:
from .routes.task_routes import bp as tasks_bp
from .routes.goal_routes import bp as goals_bp
app/models/goal.py

Consider whether the this column for Goal should be nullable. It feels odd to allow someone to create a goal that gets saved to the DB without a title.

The default is not Nullable, right?

we should use snake case for variables in python

You could also put this logic in a helper function like is_complete
| "is_complete": task.completed_at is not None}) | |
| "is_complete": task.is_complete()}) |
| task_text = f"Someone just marked the task '{task.title}' incomplete" | ||

~~Recall that the project requirement was to use the Python package requests to make 3rd party API calls.
We want folks to get practice using requests and not use the SlackClient because not all 3rd party APIs wil provide you with a custom client.
@SalmaAnany Please let me know, as a repy to this comment, how you would re-write the code for calling Slack using requests.~~

I used requests, please check the client, that's my own class using requests.

Ah yes, I meant to remove this comment after I saw your SlackClient class! Thanks for pointing me there again.

The <model>.query syntax has been deprecated since SQLAlchemy 2.0 and should not be used for new development. This needs to removed to use the newer syntax:
query = db.select(Task).where(Task.id == task_id)
model = db.session.scalar(query)See how we made a generic helper method for validating and fetching records from the DB in Flasky here on lines 10-11
