#28391 closed Bug (fixed)

Cast doesn't take into account CharField's max_length on MySQL.

Reported by: Mariusz Felisiak Owned by: Mariusz Felisiak

Severity: Normal Keywords: Cast

Description

Correct behavior, e.g. (based on db_functions/test_cast.py):

>>> Author.objects.create(name='Bob', age=1111)
>>> numbers = Author.objects.annotate(cast_string=Cast('age', models.CharField(max_length=3)))
>>> numbers.get().cast_string
111

on MySQL it returns 1111 (related with #28371).
