Ticket#33647 : bulk_update silently truncating values for size limited fields <https://code.djangoproject.com/ticket/33647>
*Approach 1:* As mentioned by Simon in this comment <https://code.djangoproject.com/ticket/33647#comment:3> we can introduce a new argument maybe named generic in the database function Cast similar to the following Cast(expr, ArrayField(CharField(max_length=20), generic=True). Although as mentioned by Mariusz in this comment <https://github.com/django/django/pull/17366#issuecomment-1763440668> "we cannot introduce new keyword arguments into database function that will be only be used to fix usage elsewhere in the Django code." But the explanation is still a little unclear to me, it would be great if someone can explain the reason. *Approach 2:* As we will not be able to introduce a new new keyword arguments into database function we can create a new database function named something like GenericCast,That will cast according to the type only without specifying the maximum length. And we will use this to the only line causing this regression in bulk_update, i.e : https://github.com/django/django/blob/a1e4e86f923dc8387b0a9c3025bdd5d096a6ebb8/django/db/models/query.py#L765 . I would like to move forward with the Approach 2. Some feedback would be great. -- You received this message because you are subscribed to the Google Groups "Django developers (Contributions to Django itself)" group.
