Example Code
from sqlmodel import Field, Relationship, SQLModel
class Address(SQLModel, table=True):
id: Optional[int] = Field(primary_key=True)
country: str
city: str
street: str
street_number: int
class Building(SQLModel, table=True):
id: int = Field(primary_key=True)
address_id: int = Field(foreign_key=f"{ADDRESSES}.id")
address: Address = Relationship()
age: int
class Config:
arbitrary_types_allowed = True
@validator('address', pre=True)
def validate_address(cls, v):
return Address.parse_obj(v)
# Importing Building produces the error "pydantic.errors.ConfigError: Validators defined with incorrect fields: validate_address (use check_fields=False if you're inheriting from the model and intended this)"Description
I want to parse a Building instance from a nested dictionary d with the Building and Address class defined in the example code.
d = {
'address': {
'country': 'US',
'city': 'New York',
'street': 'Centre St',
'street_num': 1},
'age': 40
}
So far I have been unavailable to successfully execute Building.parse_obj(d). Commenting out the validator in Building solves the pydantic error bein raised but the address of the parsed building will be a dict instead of an Address instance
