RE: [gitorious] rake db:migrate error

[Peter Kjellerstedt]

I stumbled upon the same problem the other day when I migrated our server. I have created a merge request https://gitorious.org/gitorious/mainline/merge_requests/220 that should fix the migration (once the MR is completely created, which is taking unusually long...) Otherwise you can find the actual change in my clone of Gitorious here: https://gitorious.org/~saur/gitorious/saurs-mainline/commit/edaebc8129c851b574573041a1e6817c61c1f0b2

 

The problem for you, however, is that you will have to revert the part of the failed migration that actually took place before you can apply the corrected version (unless you can revert using backups). You will have to remove the content_type column from the project_memberships table.

Hi all,

 

This is my error:

 

git@maverick:~$ pwd

/var/www/gitorious

git@maverick:~$ bundle exec rake db:migrate

.

I'm following this steps: http://gitorious.org/gitorious/pages/DebianSqueezeInstallation

 

 

How can I fix it?

Hi Peter and Rodrigo,

haven't seen this on my end but I'm helping a customer facing the same issue. Peter, thanks a lot for that reference. We may create a hotfix or hurry up the next minor version to fix this once we've fixed it in master/mainline.

cheers,
Thomas

Hi again,

we were finally able to reproduce on our end, and have pushed a minor version/hotfix for the issue.

http://blog.gitorious.org/2012/10/31/gitorious-2-3-2-released-small-hotfix-for-installationdb-setup-issue/

Peter: I'm closing your merge request as we found a simpler/more direct way of fixing the problem in the migration.

Both of you: Let us know if you have any further issues related to this. This one was a bit tricky since we haven't seen the issue locally in our own installations up till now.

Lesson learned on our part: using Rails model classes in migrations is brittle, so prefer to manipulate columns/tables directly instead.

cheers,
Thomas

Had this same issue during our upgrades last week, but we also had the following:

$ rake db:migrate

(in /var/www/vmubuntu09.tif.ti.com/gitorious)

==  AddSuspendedAtToProjects: migrating =======================================

-- add_column(:projects, :suspended_at, :datetime, {:default=>nil})

rake aborted!

An error has occurred, all later migrations canceled:

 

Mysql::Error: Duplicate column name 'suspended_at': ALTER TABLE `projects` ADD `suspended_at` datetime DEFAULT NULL

 

(See full trace by running task with --trace)

 

The work around was to ignore this specific patch, anyone else see this issue.

$ mv db/migrate/20110223130355_add_suspended_at_to_projects.rb db/migrate/.20110223130355_add_suspended_at_to_projects.rb.bak
