Hmm, one of my migrations have stopped working on #down. It still works
on #up. (It’s also possible that I never tested it for #down before, and
it never worked, heh.)
I can’t figure out why not. Pretty simple.
class WidenRequestParams < ActiveRecord::Migration
change_column :requests, :params, :string, :limit => 2048
change_column :requests, :params, :string, :limit => 1024
Up works fine. Down tells me:
Mysql::Error: You have an error in your SQL syntax; check the manual
that corresponds to your MySQL server version for the right syntax to
use near ‘limit1024 DEFAULT NULL’ at line 1: ALTER TABLE
params limit1024 DEFAULT NULL
Why is it messing up the SQL on ‘down’, but not ‘up’? Very weird.
Anyone have any ideas?
