Custom serialise/serialise on field

[farridav]

I have a field on my model of type string, that I need to encrypt within the db, and was looking for a clean way to implement this in the model, to avoid having to encrypt/decrypt within my business logic.

What is the best way to achieve this, I had looked at a few options for implicitly encrypting/decrypting

1. Override serialise/deserialise on the model
2. Have a custom field type that extends pydbantics ModelField
3. Make use of pydantics hooks for this
4. Something else?

I'm looking for some guidance on the best approach here in terms of maintainability and simplicity. Thanks
