#25002 closed Bug

Postgresql migration fails when changing a CharField to a TimeField — at Initial Version

Reported by: Dirk Uys Owned by: nobody
Component: Migrations Version: dev
Severity: Normal Keywords: migrations
Cc: Triage Stage: Ready for checkin

Description

The code from the migration is as follows:

migrations.AlterField(
    model_name='studygroup',
    name='time',
    field=models.TimeField(),
),

The field used to be a models.CharField()

The error follows:

django.db.utils.ProgrammingError: column "time" cannot be cast automatically to type time without time zone
HINT:  Specify a USING expression to perform the conversion

I can manually fix this using SQL:

ALTER TABLE "studygroups_studygroup" ALTER COLUMN "time" TYPE time USING "time"::time;
