I'm running SA 1.0.5 w/Alembic 0.7.6. Alembic is new to me. I get this:
(default-2.7)snafu$ alembic revision --autogenerate
Traceback (most recent call last):

target_metadata=target_metadata.get(name)
AttributeError: 'MetaData' object has no attribute 'get'
In my env.py:
from uta.models import Base
target_metadata = Base.metadata
And uta/models.py contains:
from sqlalchemy.ext.declarative import declarative_base
Base = declarative_base(
metadata=sa.MetaData(schema=schema_name)
)
In other words, this all looks pretty vanilla to me and is based on the
docs. Anyone recognized this error?
Thanks,
Reece
