Mass assignment with nested attributes not working

[pruchai]

I have no idea if I am doing something wrong or if I am hitting a strange use case that strong_parameters is not even supposed to handle or if it is a strong_parameters issue to begin with.

It does seem like strong_parameters is doing something, because i get a few messages, as expected.

Unpermitted parameters: created_at, updated_at
Unpermitted parameters: created_at, updated_at

But absolutely nothing is happening when I do

contact = Contact.first
contact.update(safe_params)

I enabled mysql query logging to see whats going on, and I don't even see the UPDATE or INSERT query being executed.

I have a detailed description of the issue on StackOverflow, but will copy all information into this issue, if needed and if it has something to do with strong_parameters.

Thank you.

EDIT: After further investigation it does seem strong_parameters and nested attributes related. If i remove nested attributes from my params everything works. Once i put them back in, it silently fails, so I suspect the problem lies somewhere in the way I permit them?

:host_notification_commands_attributes and :service_notification_commands_attributes get posted as an array of objects.

[
  {
    "id"=>1,
    "command_name"=>"command1",
    "command_line"=>"/usr/local/bin/command1",
    "command_description"=>"Command One",
    "created_at"=>"2015-01-19T17:24:12.000Z",
    "updated_at"=>"2015-01-21T03:29:03.000Z"
 },
 {
    "id"=>2,
    "command_name"=>"command2",
    "command_line"=>"/usr/local/bin/command2",
    "command_description"=>"Command Two",
    "created_at"=>"2015-01-19T17:24:23.000Z",
    "updated_at"=>"2015-01-19T17:24:23.000Z"
    }
]

Am i permitting them correctly?

params.require(:contact)
    .permit(:contact_name, 
        :host_notification_commands_attributes => [ :id, :command_name, :command_line, :command_description ],
        :service_notification_commands_attributes => [:id, :command_name, :command_line, :command_description])
