I am using PostgreSQL and Alembic for migration. When I added new column to
my User table Alembic generated migration with the following script:
from alembic import opimport sqlalchemy as saimport random
def generate_toke():
return random.random()
def upgrade():
op.add_column('user', sa.Column('token', sa.String(), nullable=True ))
op.execute('some code here')
What I actually want to do is autogenerating the value of token by the
generate_toke function for existing data in my DB.
Is there a solution?
