Error on rename of a column during a migration in rails?

Changing id columns in mysql is a bit tricky as all the FK must have the same data type. Can you check that all the FKs you have to that id are int(11).

Changing id columns in mysql is a bit tricky as all the FK must have the same data type. Can you check that all the FKs you have to that id are int(11). If that doesn't help, please paste the DDL of the users and any related tables.

From MySQL documentation (dev.mysql.com/doc/refman/5.0/en/alter-ta...): If ALTER TABLE dies with the following error, the problem may be that MySQL crashed during an earlier ALTER TABLE operation and there is an old table named A-xxx or B-xxx lying around: Error on rename of '. /database/name. Frm' to '.

/database/B-xxx. Frm' (Errcode: 17) In this case, go to the MySQL data directory and delete all files that have names starting with A- or B-. (You may want to move them elsewhere instead of deleting them.).

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
