Flask-SQLAlchemy Constructor

Question

in the Flask-SQLAlchemy tutorial, a constructor for the User model is defined:

from flask import Flask
from flask.ext.sqlalchemy import SQLAlchemy

app = Flask(__name__)
app.config['SQLALCHEMY_DATABASE_URI'] = 'sqlite:////tmp/test.db'
db = SQLAlchemy(app)


class User(db.Model):
    id = db.Column(db.Integer, primary_key=True)
    username = db.Column(db.String(80), unique=True)
    email = db.Column(db.String(120), unique=True)

    def __init__(self, username, email):
        self.username = username
        self.email = email

for a table with two columns, that might be acceptable, but what if I have tables with 10+ columns? do constructors have to be defined each time I define a new model?
