Another approach, probably not better, would be to only have a relationship from the user to the first movie in the list.
Between the movies have relationships with the user as a property, so you could traverse from first to last (which would have no outgoing relationships for that user). You'd have to drop and add relationships to change the ordering (instead of changing properties on a set of relationships). -----Original Message----- From: user-boun...@lists.neo4j.org [mailto:user-boun...@lists.neo4j.org] On Behalf Of Aseem Kishore Sent: Thursday, January 19, 2012 1:24 PM To: Neo4j user discussions Subject: [Neo4j] Suggestions on how to order relationships? Hi there, Take a Facebook-like example, where users can "like" different movies/music/celebs/etc. Suppose we want to let users drag-and-drop these movies/etc. on their profile pages, to let them e.g. show their favorite movies first. How would you guys recommend achieving that in Neo4j? If possible, I'd like to avoid creating a node for every relationship (redundancy/overhead as we do this more and more). I can't think of anything better than putting properties on the relationship. Maybe index numbers (e.g. rel D might have "index: 0", rel B might have "index: 1", etc.), but that's essentially reordering an array, which sucks. The other option that thus came to mind was to mimic a linked list: have an "after" property that contains the ID of the relationship this one comes after (and/or maybe a "before" property instead or in addition). Just wondering if there are better ideas! Thanks. =) Aseem _______________________________________________ NOTICE: THIS MAILING LIST IS BEING SWITCHED TO GOOGLE GROUPS, please register and consider posting at https://groups.google.com/forum/#!forum/neo4j Neo4j mailing list User@lists.neo4j.org https://lists.neo4j.org/mailman/listinfo/user _______________________________________________ NOTICE: THIS MAILING LIST IS BEING SWITCHED TO GOOGLE GROUPS, please register and consider posting at https://groups.google.com/forum/#!forum/neo4j Neo4j mailing list User@lists.neo4j.org https://lists.neo4j.org/mailman/listinfo/user
