Hello,
Help me create table with enum type column, SA do not create enum type
before table :(
And server_default doesn't set value that I expect, "actions
import_action[] DEFAULT ARRAY['copy'] NOT NULL" it set array['copy'], not
import_action['copy'] as default...
Code and exception:
from sqlalchemy import create_engine
from sqlalchemy.orm import sessionmaker
from sqlalchemy.ext.declarative import declarative_base
from sqlalchemy import Column
from sqlalchemy import Integer, UnicodeText
from sqlalchemy.dialects.postgresql import ARRAY, array, ENUM
engine =
create_engine('postgresql+psycopg2://user:password@127.0.0.1:5432/epsilon',
echo=True)
Base = declarative_base()
DBSession = sessionmaker(bind=engine)()
Base.metadata.bind = engine
import_action = ENUM('copy', 'insert', 'update', name='import_action',
metadata=Base.metadata)
class Import(Base):
__tablename__ = 'import'
id = Column(Integer, primary_key=True)
name = Column(UnicodeText, nullable=False)
actions = Column(ARRAY(import_action), server_default=array(['copy'],
type_=import_action), nullable=False)
Import.__table__.create(checkfirst=True)
sqlalchemy.exc.ProgrammingError: (psycopg2.ProgrammingError) type
"import_action[]" does not exist
LINE 5: actions import_action[] DEFAULT ARRAY['copy'] NOT NULL,
^
[SQL: "\nCREATE TABLE import (\n\tid SERIAL NOT NULL, \n\tname TEXT NOT
NULL, \n\tactions import_action[] DEFAULT ARRAY['copy'] NOT NULL,
\n\tPRIMARY KEY (id)\n)\n\n"]
