如何在postgresql数组字段上使用ilike和任何sqlalchemy？

from sqlalchemy import create_engine, Column, Integer, String, ARRAY
from sqlalchemy.orm import sessionmaker
from sqlalchemy.ext.declarative import declarative_base

# 创建数据库连接
engine = create_engine('postgresql://username:password@localhost:5432/db_name')
Session = sessionmaker(bind=engine)
session = Session()

# 创建基类
Base = declarative_base()

# 定义模型类
class MyModel(Base):
    __tablename__ = 'my_table'
    id = Column(Integer, primary_key=True)
    array_field = Column(ARRAY(String))

# 查询包含特定字符串的数组元素
query = session.query(MyModel).filter(MyModel.array_field.any_(MyModel.array_field.ilike('%keyword%')))
results = query.all()

# 打印查询结果
for result in results:
    print(result.id, result.array_field)

# 关闭数据库连接
session.close()
