Comment:
That did the trick! Thanks @mjtamlyn! Here's the working change for the
example above:
{{{
from django.utils.six import with_metaclass
class IntStoredAsStringField(with_metaclass(models.SubfieldBase,
models.CharField)):
def __init__(self, max_length=2000, *args, **kwargs):
super(IntStoredAsStringField,
self).__init__(max_length=max_length,
*args, **kwargs)
def to_python(self, value):
if isinstance(value, int):
return value
return int(value)
def get_prep_value(self, value):
return smart_text(value)
}}}
