title: DataError value too long for type character varying(100)
body: <p>I need to make changes to my profiles object at the admin site in Django, but when I click save, I get the error DataError at /admin/profiles/profiles/31/change/ value too long for type character varying(100). The weird thing is, it worked when I made changes to the same field locally, but when I deployed to Heroku, it gave me the 'DataError'. My image url is the only long string in my object. Side note, I am still using sqlite3 with Heroku because the data is very small.</p>
