Alembic autogenerate ignore non mapped tables.

[Srikanth Bemineni]

Hi,

When I auto generate a migration using alembic, it automatically drops some dynamically created tables which are in the DB schema. These tables are dynamically created by my application. These class don't inherit declarative base. They are added to declarative base by the application during run time , but not during migration creation. How can alembic ignore these tables.?

check out the include_object parameter
http://alembic.zzzcomputing.com/en/latest/api/runtime.html#alembic.runtime.environment.EnvironmentContext.configure.params.include_object
which is the catchall hook for "ignore item" rules.
