Attachments and plugin assets directory not writable in information panel.

/.openshift/action_hooks/post_deploy

in 23 line:
if ! /usr/bin/mysql -h "$OPENSHIFT_MYSQL_MYSQL_MYSQL_DB_HOST" \

after I successfully deployed the app on my openshift namespace, I want to enable the email notification. so I add config/configuration.yaml, content:

production:
email_delivery:
delivery_method: :smtp
smtp_settings:
address: "localhost"
port: 25

after push and re-deployed, it's still complaining no email configuration is set. So I change the environment to "default", it works.

I am trying to install plugins but they won't appear at administration --> information, no matter what I do.

I first thought it was a matter of redmine_charts2 but pharmazone helped me and it was obvious I'm doing something wrong (or there's a problem with redmine 2 at OpenShift).

This is my problem: I follow plugin installation instructions (script/rails plugin install, rake, commit, push) but plugins don't appear.

The only thing i've not done to the letter is rake migration. Since I don't run Redmine locally, when I perform any migration I change config/database.yml. I change production config, which has variables like $OPENSHIFT_DB_HOST to OpenShift remote database. After running the migration I checkout it to its original state.
