I have this validation

'f1': {'in': {'dbset': lambda db: db.where(db.A.f2 == session.f2)}}

In another way:

def val_f2(db):
    print(session.f2)
    return db.where(db.A.f2 == session.f2)
    
'f1': {'in': {'dbset': lambda db: val_f2(db)}}

The problem I have is that lambda runs only once and after that first time does not come to run, then it is always calling db.where from the first condition. I can check it with the print() that only runs once
