内容类型定义

FOOBAR_PG = [
    Column("num", Float),
    Column("text", String, nullable=True)]

FOOBAR_SCHEMA = {
    "$schema": "https://json-schema.fullstack.org.cn/draft-07/schema#",
    "type": "object",
    "properties": {
        "num": {"type": "number"},
        "text": {"type": "string"}
    }
}
async def foobar_validator(context, value):
    return True


class IFoobarType(Interface):
    foobar = PatchField(
        PGListField(
            title="foobar",
            json_schema=FOOBAR_SCHEMA,
            validator=foobar_validator,
            pg_schema=FOOBAR_PG,
            pg_table="foobar",
            required=False,
        )
    )
