Redmine plugins rely on Rails engines to add functionalities to the application.
Installing a plugin¶
1. If you're using a 0.7.x release, you need to install the Rails engines plugin (make sure to get the Rails 2.0.2 version). As of 0.8.0, Rails engines is included in Redmine, so skip this step unless you're using an older Redmine version.
ruby script/plugin install http://svn.rails-engines.org/engines/tags/rel_2.0.0/ mv vendor/plugins/rel_2.0.0 vendor/plugins/engines
2. Then, copy your plugin directory into
3. If the plugin requires a migration, run the following command to upgrade your database (make a db backup before):
rake db:migrate_plugins RAILS_ENV=production
4. Restart Redmine
You should now be able to see the plugin list in Administration -> Plugins and configure the newly installed plugin (if the plugin requires to be configured).
A full list of available Redmine plugins can be found at the Redmine plugin list.
There is a step-by-step tutorial about writing a plugin. Some more (detailed) information is collected and stored in the "plugin internals" page.
More (general) developer information can be found in the Redmine Developer Guide.
