Plugin not loaded when server starts [but loaded fine in script/console and tests]
Added by Adam Walters over 15 years ago
Hello,
I'm writing a plugin and having some issues getting it to work in when the server is actually running. When i go into the console, i'm 100% sure my plugin is loaded, as i can call the newly included methods added onto Issues. However, these methods are not present when the server is actually running and displaying pages. Is there some reason why these two should be inconsistent?
I followed the plugin pattern used here: http://github.com/edavis10/redmine_rate/blob/4666ddb10e1061ca3ef362735d0d264676b99024/lib/rate_users_helper_patch.rb
as instructed by the plugin developer wiki.
This is all occurring within the development environment
Redmine version: 0.8.0.devel1858

I little more testing and i believe i'm on the correct path. Somehow the module i include into Issue.rb is being removed. If i restart the server, the first request DOES show that my module is in fact included, and my plugin code runs. However, ALL subsequent requests DO NOT have my plugin mixed into the Issue object. Why would this be disappearing?

It's because in development mode, Rails unloads all of it's classes in the application (e.g. Issue) after each request but not in plugins. On the second request, the plugin is patching the old class which isn't around anymore so you don't see your changes. To work around this, wrap all your include
calls in Dispatcher.to_prepare

I'm going to be updating my plugins and writing about this soon

Adam (and anyone else):
I've written a blog post that outlines the Dispatcher.to_prepare
in more detail. You might find it useful.
