alembic-offline 1.0.0

Usage

In your version file:

from sqlalchemy import INTEGER, VARCHAR, NVARCHAR, TIMESTAMP, Column, func
from alembic import op

from alembic_offline import phased, execute_script

from tests.migrations.scripts import script

revision = '1'
down_revision = None


@phased
def upgrade():

    op.create_table(
        'account',
        Column('id', INTEGER, primary_key=True),
        Column('name', VARCHAR(50), nullable=False),
        Column('description', NVARCHAR(200)),
        Column('timestamp', TIMESTAMP, server_default=func.now())
    )
    yield
    op.execute("update account set name='some'")
    yield
    execute_script(script.__file__)


def downgrade():
    pass

Will give the sql output (for sqlite):

-- Running upgrade  -> 1

-- PHASE::0::;

CREATE TABLE account (
    id INTEGER NOT NULL,{space}
    name VARCHAR(50) NOT NULL,{space}
    description NVARCHAR(200),{space}
    timestamp TIMESTAMP DEFAULT CURRENT_TIMESTAMP,{space}
    PRIMARY KEY (id)
);

-- PHASE::1::;

update account set name='some';

-- PHASE::2::;

-- SCRIPT::/home/vagrant/workspace/alembic-offline/tests/migrations/scripts/script.pyc::;

INSERT INTO alembic_version (version_num) VALUES ('1');
