DRF Validating instance saved in database
I Have an issue with Django / DRF, I want to validate data already saved in database.
(it hasn't be fully validated before, because at the create / update of it, I am permissive and I want to allow the user to do certain things and correct it later)
But here's the thing: currently, in order to validate it, I have so serialize it, to have dict data, and then this data needs to go through a validation serializer.
But it seems a bit overkill and it also seems to have some issues in it (need to re-implement a full validation in addition of the create / update one, might not follow all the validation rules implemented somewhere else)
How could I do it ?
