Add custom fields and post to a Google service support from plugin
I've checked help and some other plugins, but variants I've see are very different.
1. How to define data type and appearance for editable properties I'm adding with Patch. For example, I need to add a boolean field to Issue. How can I mark get/set and datatype for it?
2. I'm trying to use a Google service with my Redmine project. Which GEM file I need (simple OmnuAuth? or one of 2 google-specialized)?
3. How to capture controller hooks and send authorized POST requests when the proper hooks are called? I'm not sure about standard Ruby functions.
