示例1: run_migrations
# 需要导入模块: from alembic.operations import Operations [as 别名]
# 或者: from alembic.operations.Operations import context [as 别名]
def run_migrations(self, **kw):
"""Run migrations as determined by the current command line
configuration
as well as versioning information present (or not) in the current
database connection (if one is present).
The function accepts optional ``**kw`` arguments. If these are
passed, they are sent directly to the ``upgrade()`` and
``downgrade()``
functions within each target revision file. By modifying the
``script.py.mako`` file so that the ``upgrade()`` and ``downgrade()``
functions accept arguments, parameters can be passed here so that
contextual information, usually information to identify a particular
database in use, can be passed from a custom ``env.py`` script
to the migration functions.
This function requires that a :class:`.MigrationContext` has
first been made available via :meth:`.configure`.
