Rails timestamps not updating Xxx virtual dating simalators
I found this SO article: Seems like maybe the default behavior changed, and if I recreated my development database from migrations, then the file wants to change by having "not null" removed. So what's happened is that maybe the behavior t.timestamps changed, and I rebuilt the DB from the migrations.I suppose it might be worth downloading my production DB and running annotate against that and seeing if the "not null" changes in the model annotations.update_attribute Updates a single attribute and saves the record without going through the normal validation procedure.This is especially useful for boolean flags on existing records.
AFAICT Rails 3.1 does not populate timestamps on a join table.

Besides of this Rails developers don’t prefer to write raw SQL because if you want to migrate through Postgre SQL to My SQL for example you may have to fix much raw SQL code.
Check out official documentation to get examples how to write raw SQL in migrations.Of course you may create your own dependent files and then load them in the file but anyway you have to worry about what to do on second run. For example create rake tasks, of even going to production console and write code there after deploying (I hope you don’t do it).
