Lets say d is your device object and you set its location relationship using the syntax d.location = '/NY'

In the process you've destroyed the location relationship and replaced it with a string! Functions like d.setLocation('/') won't work on this object type.

d.location.__class__ will show it's a string.

To delete the string, del d.location

d.location.__class__ will show result in an error since d.location doesnt exist.

Let's recreate the device relationships using it's schema by:


relnames = d.getRelationshipNames() for name, schema in d._relations:

   try:
       d._setObject(name, schema.createRelation(name))
   except:
       pass


d.location.__class__ will show it's a relationship and now d.setLocation('/') will work.

This will work for any relationship on a device object.
