我在 postgresql 表中有一个具有 citext 数据类型的列。我想将该列添加到烧瓶 appbuilder 中的模型中。
下载sqlalchemy-citext库并添加如下。在烧瓶应用程序构建器中创建了以下模型。
class TestUsers1(Model):
__bind_key__ = 'pg'
__table_args__ = {"schema": "sample"}
uuid = Column(UUID(as_uuid=True), primary_key=True,default=uuid.uuid4)
company_code = Column(CIText())
first_name = Column(String(255))
def __repr__(self):
return self.name
当我执行相关视图时，它会给出以下错误。

有没有办法在 sqlalchemy 中添加 citext 列？
