#25767 closed Bug (fixed)

integer_field_ranges are incorrect for MySQL backend

Description (last modified by George Marshall)

The integer ranges for PositiveSmallIntegerField and PositiveIntegerField are reflective of UNSIGNED INT and UNSIGNED BIGINT. When the ORM actually uses UNSIGNED SMALLINT and UNSIGNED INT when creating these fields.

The side effect of this is that data will pass validation checks, but will be munged by the database.

Since this a bug in a new feature (introduced in 1.8) that can possibly lead to data loss I think this is worth a backport.
