Example Code

fromtypingimportLiteral, Union, OptionalfromsqlmodelimportSQLModel, FieldclassBar(SQLModel):
class_type: Literal["bar"] ="bar"name: strclassFoo(SQLModel):
class_type: Literal["foo"] ="foo"name: strid: Optional[int]
classFooBar(SQLModel, table=True):
id: int=Field(default=None, primary_key=True)
data: Union[Foo, Bar] =Field(discriminator="class_type")

Description

  • No support for Pydantic 1.9's implementation of discriminated union

Wanted Solution

Would like to have support for discriminated union in SQLModel-classes
