I'm not sure how to define a create schema foo
migration? My Model looks like this (I'm using Flask-Migrate):
class MyTable(db.Model):
__tablename__ = "my_table"
__table_args__ = {"schema": "foo"}
id = ColumnPrimKey()
name = Column(Text, unique=True, nullable=False)
When I execute mange db upgrade
I get a failure because the schema "foo" does not exist. How can I add a migration for the schema with SQLAlchemy and Alembic?
I accomplished this by modifying the migration upgrade
command to first run:
op.execute("create schema foo")
And in the downgrade
function
op.execute("drop schema foo")
So the whole migration file looks something like:
from alembic import op
import sqlalchemy as sa
# revision identifiers, used by Alembic.
revision = '6c82c972c61e'
down_revision = '553260b3e828'
branch_labels = None
depends_on = None
def upgrade():
op.execute("create schema foo")
...
def downgrade():
...
op.execute("drop schema foo")
