Creating has_many relation with self
11 January 2010 at 12:11pm
Can a dataobject have a has_many relation with self. I'm trying to set up a list of definitions, then include related terms. So each term would have to have a has_many relation with other terms.

I think you would need a many_many relationship for that as a Definition would have many Related Terms and each of those Related terms would probably have multiple definition it relates to.
You can try add a many_many / belongs_many_many to the object and try it out. I think it *should* be fine with a many_many relationship on itself. Try it out and see what happens

From IRC:
michaelcole: Hello!
michaelcole: I'm just checking out Silverstripe. How could I model a "has many reference to self" relationship with the ORM?
simon_w: static $has_many = array ('LotsOfMe'=>__CLASS__); static $has_one = array('OneOfMe' => __CLASS__);
michaelcole: Cool! Sounds simple. I like it!
