AttributeError: 'str' object has no attribute 'unwrap'

I’m trying to retrieve rows from the database and get this error. My table looks as follows:

class Post(Model):
    date = DateField()
    user = ForeignKeyField(User, backref='numbers')
	number1 = DecimalField(6,2)
    number2 = DecimalField(6,2)

    class Meta:
		database = SqliteDatabase('data.db')
        primary_key = CompositeKey('date', 'user')

What can be the problem?

You need to read the docs. It’s nowhere indicated that you pass string field-names into the select() method. You use the field instances themselves.

Post.select(Post.date, Post.number1, ...)

Also selecting Post.user will just grab the user_id.
