Instance Method Details

#get_instance_with_attributes(path) ⇒ Object

This is a hacky workaround used to get an instance without executing the methods on it. It fails if a message is passed in the path or if the message field on the any of the methods are *.

def get_instance_with_attributes(path)
  if path =~ /#/
    raise "Does not work with messages in the path."
  end
  fake_message = "callingWithAFakeMessage"
  empty_instance = @evm.instantiate("#{path}##{fake_message}")
  instance_name = empty_instance.name
  @evm.instance_get(instance_name)
end

#instantiate_or_raise(path, message) ⇒ Object

Instantiate an automate instance at path or raise an exception with the message provided if the instantiation returns nil (not found).

  if object.nil?
    raise message
  end

  object
end

#resolve_vm(lookup_order: [:rootvm, :dialog_id, :provision], dialog_name: 'dialog_target_server') ⇒ Object

Condense multiple types of VM lookups into one call. This is useful when making an Automate method generic enough to be used during provisioning, with a custom button, or as a catalog item.

Lookup methods used and their order can be overridden by specifying :lookup_order

The dialog name that may hold the miq ID is specified via :dialog_name
