Plugins¶

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 #{RAILS_ROOT}/vendor/plugins. If you are downloading the plugin directly from GitHub, you can do so by changing into you plugin directory and issuing a command like git clone git://github.com/user_name/name_of_the_plugin.git.

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).

Plugin list¶

A full list of available Redmine plugins can be found at the Redmine plugin list.

More plugins (some in very early development), which are not listed at the Redmine plugin list but are publicly available on GitHub, can be found using a search like this.

Writing plugins¶

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.
