Hello, I know this issues is a couple of weeks old, but was still one of the more recent hits I found when looking for discussions of apn_on_rails.

This is really an ActiveRecord issue ... device.id is the database identifier of the record, not the APN token (which is "token"). In the code above, instead of assigning the to token to "device.id", assign it to "device.token". Then save the record: "device.save", and if you get back 'true', you can procede with the rest of your code. As id is an int, you couldn't put a string in there, which is what the token is. You'd get an error when trying to save, and the token field wouldn't be populated. Just remember, unless you're stepping off the 'golden path' (and only do so when you need to and know what you're doing), with ActiveRecord, the 'id' field does not have any business data in it, it is just there to identify the record itself, in most cases, automatically assigned (possibly not with Oracle, but that's another story). It can be useful to assign without having to actually retrieve a record, e.g., class User < ActiveRecord::Base belongs_to :office end Then, if you know the LA office is #3 e.g., you can do someuser.office_id = 3 someuser.save instead of someuser.office = Office.find_by_name("LA") someuser.save which will have to fetch another record, if Rails hasn't cached it already. It is frequent in controllers you'll have a record number rather than a record, coming back in the params from a form. But in many cases, you can pretty much ignore the ID field.
