Had an issue when clicking a meal tracker add button @MihaiZecheru:

insert or update on table "logged_meals" violates foreign key constraint "logged_meals_user_id_users_id_fk"

Could this be because of the way you're inserting the meal? I'll look deeper into the issue later, but a good place to start looking in the meantime would be in your insert procedure and/or the db schema for this table.

Ah, I forgot to specify that there has to be a dummy user in the DB for this to work.

Create a user in the Users table with ID=TEST_USER

Changes look great and work great on the local device. A few nitpicks when it comes to styling and adding some comments for things TODO later. Overall, great work!

Please fix before Friday. Message me on Discord if you have any questions.

Looks good to me! There are a few things yet to implement but those come later when we're ready.
