use json.

[linpan]

data: dict = Field(default={}, sa_type=JSON)

However, it cannot be deserialized back to the Pydantic type normally.

i wonder is there any way provider an custom handler like mybatis BaseTypeHandler

[cjdxhjj]

Perhaps it can be automatically recognized by the framework.

there are only two data type for pydantic, the one is object and another is list
