everyone.
Got a problem here.
I have some Pydantic model with some attrs and 99 % of the time I want it that way. But for the remaining 1 % at a time I want it to have some additional attribute.
I can set it dynamically using an extra attribute with the Config object and it works fine except the one thing: Pydantic knows nothing about that attr. So when I want to modify my model back by passing response via FastAPI, it will not be converted to Pydantic model completely (this attr would be a simple dict) and this isn't convenient.
Other possible options:
- Just define another model with that attr. I don't consider it as I want to modify Pydantic model itself, converting to dict back and forth inefficient, model is nested and huge.
- Make attr Optional. Schema will have it with None and it'll be passed everywhere. Not optimal, because as I said, model in general doesn't need this attribute.
So what I want is:
Maybe it's possible for Pydantic to specify that dynamically can be set attribute of specific type for this model (because I don't have stochastic mutation, I definitely know what would be added), but the general instance of that class will not have it anywhere. And when I set it, Pydantic will handle new structure of my model and will not have any problem with that. I couldn't find anything similar by myself.
Thanks in advance. Would be glad for any help.
P.S. I hope I explained myself very clearly and the code is unnecessary as problem's very straightforward.
