In the video, we create the following :
- students.db, the SQLite database
- Student, our model (capital S) Then we run the following : db.create_tables([Student], safe=True) (capital S again)
And the name of the table, as we see it in SQLite is student (without the capital S). I don't see where we create anything called student (without the capital S) . Is it just because names for SQL tables don't use capital letters?

This brings up the interesting case of what happens when you have two Models with same name but different case such as User and UseR. These are distinct within Python. Now when peewee creates the tables for these using:
DATABASE.create_tables([UseR, User, Post, Relationship], safe=True)
Whichever of the two Models is listed first will be created, the second will not be created as the table appears to have been created.
There is a Meta parameter you can set to force the table case (but it's not used in normal practice):
class ModelOne(Model):
class Meta:
database = db
db_table = 'modelOne'
