Overview

Presenter for template listing (mixed VM and Container templates).

Handles both Models::Vm and Models::Container via duck typing. Both models share: vmid, name, type, node, maxdisk, tags.

Examples:

Using with formatter

presenter = Template.new
formatter = Formatters::Table.new
output = formatter.format(templates, presenter)
