flask db migrate for 'creat view' / 'drop view'

[learnersbox]

How to integrate CREATE VIEW and DROP View as shown in wiki "Views" ?

I have added the code in my models.py but it seems flask db migrate unable to recognise the same.

(.venv) d:\MyCodes\flask>flask db migrate -m "base-0.02"
INFO [alembic.runtime.migration] Context impl SQLiteImpl.
INFO [alembic.runtime.migration] Will assume non-transactional DDL.
INFO [alembic.env] No changes in schema detected.

Any help please ?

alembic autogenerate does not detect views. so you need to edit your migration files directly in order to add new views.
