Utility method to convert a VMware managed object into an attribute hash. This should only really be necessary for the real class. This method is expected to be called by the request methods in order to massage VMware Managed Object References into Attribute Hashes.
# File lib/fog/vsphere/compute.rb, line 95 def convert_vm_mob_ref_to_attr_hash(vm_mob_ref) return nil unless vm_mob_ref props = vm_mob_ref.collect!(*ATTR_TO_PROP.values.uniq) # NOTE: Object.tap is in 1.8.7 and later. # Here we create the hash object that this method returns, but first we need # to add a few more attributes that require additional calls to the vSphere # API. The hypervisor name and mac_addresses attributes may not be available # so we need catch any exceptions thrown during lookup and set them to nil. # # The use of the "tap" method here is a convenience, it allows us to update the # hash object without explicitly returning the hash at the end of the method. Hash[ATTR_TO_PROP.map { |k,v| [k.to_s, props[v]] }].tap do |attrs| attrs['id'] ||= vm_mob_ref._ref attrs['mo_ref'] = vm_mob_ref._ref # The name method "magically" appears after a VM is ready and # finished cloning. if attrs['hypervisor'].kind_of?(RbVmomi::VIM::HostSystem) begin host = attrs['hypervisor'] attrs['datacenter'] = parent_attribute(host.path, :datacenter)[1] attrs['cluster'] = parent_attribute(host.path, :cluster)[1] attrs['hypervisor'] = host.name attrs['resource_pool'] = (vm_mob_ref.resourcePool || host.resourcePool).name rescue nil rescue # If it's not ready, set the hypervisor to nil attrs['hypervisor'] = nil end end # This inline rescue catches any standard error. While a VM is # cloning, a call to the macs method will throw and NoMethodError attrs['mac_addresses'] = vm_mob_ref.macs rescue nil # Rescue nil to catch testing while vm_mob_ref isn't reaL?? attrs['path'] = "/"+vm_mob_ref.parent.path.map(&:last).join('/') rescue nil attrs['relative_path'] = (attrs['path'].split('/').reject {|e| e.empty?} - ["Datacenters", attrs['datacenter'], "vm"]).join("/") rescue nil end end
returns vmware managed obj id string

returns the parent object based on a type provides both real RbVmomi object and its name. e.g.
# File lib/fog/vsphere/compute.rb, line 137 def parent_attribute path, type element = case type when :datacenter RbVmomi::VIM::Datacenter when :cluster RbVmomi::VIM::ClusterComputeResource when :host RbVmomi::VIM::HostSystem else raise "Unknown type" end path.select {|x| x[0].is_a? element}.flatten rescue nil end
