I just created session with rake db:sessions:create and run the migration also. When I run my apps, my db barfed out saying that the length of session_id is too long. When I checked into my db, the length of session_id column in the sessions table, it was 255 of character varying. I then changed it to 500 character varying and it works. But that would be too long. Does anybody know the exact length of this field?
Thank you in advance.
