Flask data migration example

The following will run the migrations (with seed data).

pip install -r requirements.txt
python app.py db upgrade

Model before migration:

class Test(db.Model):

    id = db.Column(db.Integer, primary_key=True)
    base64data = db.Column(db.String(128))

Model after migration:

class Test(db.Model):

    id = db.Column(db.Integer, primary_key=True)
    hexdata = db.Column(db.String(128))

Migrations:

• Initialize db with seed data.
• Migrate base64data to hexdata
