run_migrations

run_migrations(**kw) → None

Run the migration scripts established for this MigrationContext, if any.

The commands in alembic.command will set up a function that is ultimately passed to the MigrationContext as the fn argument. This function represents the “work” that will be done when MigrationContext.run_migrations() is called, typically from within the env.py script of the migration environment. The “work function” then provides an iterable of version callables and other version information which in the case of the upgrade or downgrade commands are the list of version scripts to invoke. Other commands yield nothing, in the case that a command wants to run some other operation against the database such as the current or stamp commands.

Parameters:

• **kw – keyword arguments here will be passed to each migration callable, that is the upgrade() or downgrade() method within revision scripts.
