I've been learning silverstripe for a little while now but I've come across an issue that I hope someone can help me with. I've created a DataObject (let's call it PaperClip). I want to attach my PaperClip to a Page - sure - I form an extension using PaperClip and decorate SiteTree or Page with it. In my Page I specify "$has_one = array('PaperClip'=>'PaperClip')". Now, how do I specify the reverse relationship in my PaperClip object (Has One Page) without modifying the PaperClip DataObject or PaperClip Extension code?
The goal is to abstract my PaperClip so it can be attached to any object type, a Page, a Memo, an Envelope, a Dog.
Maybe something like: mysite/_config -> PaperClip::$has_one = array('Dog'=>'Dog'); Should I wish to attach my PaperClip to a dog.
