Alexey Bezhan	3a15a7e783	Set Template.hidden as nullable before the new app code gets released ... Since the application code gets released after the migration setting a new Template field as non-nullable prevents new templates from being created by the existing application instances. This splits the migration to set fields as nullable first and then update existing records once the application code has been released. 0168 is modified not to run UPDATE query or set non-nullable flag in staging and production. 0169 is added to rollback preview.	2018-02-26 10:46:20 +00:00
Alexey Bezhan	6d1439e39a	Add a DB migration to create Templates.hidden column ... Creates the column as nullable, sets the value to false for all existing templates and template versions and then applies a not-nullable constraint. All future Templates are created with `False` as the default set in SQLAlchemy.	2018-02-23 17:52:24 +00:00
