Unable to rename iPad

[csfjeff]

I used to be able to rename iPads via Ruby-JSS but recently I'm running into errors when I try.

Basically if I do something simple like the following:
`#!/usr/bin/ruby

require 'ruby-jss'

JSS::API.connect(:user => "user", :pw => "password", :server => "jss", :port => "8443")
ipad = JSS::MobileDevice.fetch :serialnumber => "serial#"

ipad.name = "Test name"
ipad.save
`

It fails with the following errors:

/Library/Ruby/Gems/2.6.0/gems/ruby-jss-4.2.4/lib/jamf/api/connection/classic_api.rb:267](coderunner:///Library/Ruby/Gems/2.6.0/gems/ruby-jss-4.2.4/lib/jamf/api/connection/classic_api.rb#267:0!):in `handle_classic_http_error': Illegal state. Both processManagerUUID and mdmCommand are null. (Jamf::BadRequestError)

I note that it does seem to be calling 'send_mdm_command' routines, and according to JAMF API change documents it looks like as of 11.21.0 they removed both the 'POST /computercommands/command' and 'POST mobiledevicecommands/command' APIs - I suspect this is the heart of the issue.

I can edit and save other attributes such as building and department, it's only when I try to change the name that this issue comes up. I suspect Ruby-JSS is using an mdm command to do the rename.

Sorry for the delay over the Thanksgiving weekend.

I suspect you're correct about the cause. I'll see if I can get a quick fix in place for the deprecated Classic API MDM stuff, at least this specific issue.

Now that Xolo has been released, I hope to be able to spend at least some of my time catching up with API changes in ruby-jss.

Will update here when I have something.

Cheers,

No apologies required - I for one very much appreciate all the work you do on this and how responsive you are!

I just made v5.0.0b1 available, which should hopefully fix nearly all MDM command pushes. The Jamf::MDM mixin module, in .../lib/jamf/api/classic/api_objects/mdm.rb has been fully changed to use the JP API endpoints where possible. I haven't implemented any new commands, just fixed the ones already defined in that module.

I've tested it here for renaming an iPad, and it seems to work.

to install it yourself gem install ruby-jss -v 5.0.0b1 --pre

It will also install a new gem dependency pixar-ruby-extensions, which we use in other projects, and will allow us to eventually get rid of the JamfRubyExtensions module built into ruby-jss

Let me know how it works for you! I'll now start testing all the other updated methods in the MDM module :-)

Update: use 5.0.0b2 - fixed a few bugs.

Cheers,
