Example Code

class Table(SQLModel):

Description

Hi,

I would like to alter a table’s primary key’s behaviour so I can use, for example, UUID; like

class Table(SQLModel):
    id: Optional[str] = Field(default=uuid.uuid4().hex, primary_key=True)

The expected behaviour should be replacing each uuid every time a new “record” is created.

Any options?

Thanks!

I believe you want to use the default_factory parameter: https://pydantic-docs.helpmanual.io/usage/models/#field-with-dynamic-default-value
