How to uninstall Easy Redmine plugins

When you want to get rid of a plugin from Easy Redmine, you must uninstall it and unmigrate it from your database. The most common mistake is that a plugin is simply deleted from filesystem, but not removed from database. You may then come across internal errors on different pages.

The production log would contain something like:

The single-table inheritance mechanism failed to locate the subclass: 'EpmActivityFeed'...

These are the correct ways to uninstall Easy plugins

Uninstall all plugins with confirmation

rake easyproject:uninstall:all_plugins RAILS_ENV=production

 

Uninstall a single plugin

rake easyproject:uninstall:plugin RAILS_ENV=production NAME=easy_budgetsheet

 

Already deleted plugins must be restored in the filesystem and then uninstalled.
