python - How do I use Flask Migrate to create a SIMILAR TO constraint? -


i build constraint on status, using flask migrate. status not yet exist.

my model includes line:

status = db.column(db.string(120), unique=false)

i add following constraint on status in addition create status:

alter table inventory add constraint "statuscheck" check ("status" similar 'ordered|received|ready|faulty|void');

you can write sql in migration scripts. see http://alembic.zzzcomputing.com/en/latest/ops.html#alembic.operations.operations.execute.

side note: flask-migrate wrapper alembic, make flask friendly. question alembic.
