Disable auto-generation for specific fields in Polyfactory with Pydantic models?

[megetron3]

Hi,

I’m using Polyfactory with a Pydantic class and would like to stop auto-generating values for fields like some_text_variable without explicitly using Ignore() for each one.

Example:

from polyfactory.factories.pydantic_factory import ModelFactory
from pydantic import BaseModel

class SomeModel(BaseModel):
    some_text_variable: str
    another_variable: int

class SomeFactory(ModelFactory[SomeModel]):
    some_text_variable = Ignore()

Is there a way to globally disable or streamline this without manually defining each field?

Thanks!

Hi, this is not supported as a setting but could be achieved by overriding should_set_field_value.

Something like

class Base(ModelFactory):
     __is_abstract_factory__ = True
    

    @classmethod
    def should_set_field_value(cls, field_meta: FieldMeta, **kwargs: Any) -> bool:
           return super().should_set_field_value(field_meta) and hasattr(cls, field_meta.name)

Note above is untested and may not fully work for some cases around inheritance
