[FEAT] Ignore validation errors

[rm-shanebreeze]

Is there a way to configure patito Models to ignore certain validation errors (e.g. type_error.superfluoscolumns) in the model class rather than catching and checking errors?

[dsgibbons]

patito.validators.validate has an allow_superfluous_columns argument (https://github.com/JakobGM/patito/blob/main/src/patito/validators.py#L89). Can you give an example where you need this logic to live in the model rather than in the call to validate?

Patito should be better integrated with pydantic features. Configuration should be set in ConfigDict, not on the fly through the validate arguments. See how you do that the pydantic way:

from pydantic import BaseModel, ConfigDict
import patito as pt

class PydanticModel(BaseModel):
    model_config = ConfigDict(extra="allow")
        
    a: int

PydanticModel.model_validate({"a" : 1, "b": 1}) # works
# PydanticModel(a=1, b=1)

class Model(pt.Model):
    model_config = ConfigDict(extra="allow")
        
    a: int

Model.validate(Model.examples().with_columns(b = 1)) # fails
# Superfluous column (type=type_error.superfluouscolumns)
