Re: Error when change a CharField to IntegerField

Hi, did the column had previus non-integer data in it?

2014-12-30 8:52 GMT-05:00 Neto <paulosouzamaciel@gmail.com>:

I changed a CharField to IntegerField and when I did ./manage.py migrate, appeared the message on terminal:

django.db.utils.ProgrammingError: column "rotulo" cannot be cast automatically to type integer HINT:  Specify a USING expression to perform the conversion.

What is it?
