ok, I'm having difficulty with heroku, they are having some build problems...

I'll try later.  I guess commenting out the # rename table in change def should work?  

I was puzzled because the column title started with a capital letter, it worked fine in sqlite, but generated errors in postgres.  (so the quickest fix for me was to edit the column in postgress directly).   I belive I skipped this migration before, but I forget how I did that. 

is there anything that keeps you from using postgres for development?

 

Thanks,

Hi, I got stuck on a migration (basically to fix a column name).  I actually went into the table itself and corrected the problem.  My herkou migration gets stuck, and I've got other migrations behind it that aren't running.

If you've already fixed the table manually, then you don't need to run the migration at all.  You have 3 hackish options

1.  Just delete the migration and update the old migration so it uses the correct column name.

2.  Insert the timestamp of the migration that you want to skip to a table called schema_migrations (not sure if this is

the exact name).  Rails basically checks this table to see which migrations need to run.

3.  Edit the migration so that it doesn't do anything, commit, deploy, run db:migrate.  Edit the migration again, commit,

deploy, run db:migrate.  The second db:migrate should not run the edited migration file.

May I ask why you decided to fix the table manually?

 

What should I do?

Thanks,

Joe
