Using Optional[] is all that we need to indicate that a field is nullable so we don't need to also include mapped_column with nullable=True.
| completed_at: Mapped[Optional[datetime]] = mapped_column(nullable=True) | |
| completed_at: Mapped[Optional[datetime]] |
Here's the SQLAlchemy documentation about nullability

Could we use the to_dict method you wrote in Goal?
| return dict( | |
| id = goal.id, | |
| title = goal.title, | |
| tasks = [task.to_dict() for task in goal.tasks] | |
| ) | |
| return goal.to_dict() |

|
|
||
| # Assign valid tasks to this goal | ||
| for task in valid_tasks: | ||
| valid_tasks_ids.append(task.id) | ||

What if we don't need to unlink the tasks because we can just replace them?

It might be nice to provide even more details in the response you send back so that the client knows how to fix up the request body they will re-send.
| response = {"details": "Invalid data"} | |
| response = {"details": f"Invalid data for field: {error.args[0]}"} |
For example, this would evaluate to "title" for example if I sent a bad request body to create a Task.

Prefer all the logic related to calling Slack to be in a helper function (maybe like call_slack_api) to make this route more concise and single-responsibility.

This string is a constant value so we should name the variable with all capital letters.
| path = "https://slack.com/api/chat.postMessage" | |
| PATH = "https://slack.com/api/chat.postMessage" |
| body ={ | ||

Also prefer the channel to be referenced by a constant variable too.
| body ={ | |
| "channel": "task-notifications", | |
| SLACK_CHANNEL = "task-notifications" | |
| body = { | |
| "channel": SLACK_CHANNEL, |
