如何在配方中访问Chef LWRP属性

使用一些默认的Chef资源，可以在调用它们之后访问它们的一些属性

# recipes/default.rb f = file "/tmp/file_resource" do owner "root" group "root" mode "0755" action :create end log "Path to my file is #{f.path}" # outputs "/tmp/file_resource" 

如何在自定义LWRP中实现（这是一个示例）

 # resources/default.rb actions :create default_action :create attribute :relative_path, :kind_of => String, :name_attribute => true attribute :full_path, :kind_of => String 

在这个提供程序中，我试图将new_resource.full_path的属性更新为等于文件资源的路径

 # providers/default.rb action :create do f = file "/path/to/my/resource/#{new_resource.relative_path}" do owner "root" group "root" mode "0755" action :create end new_resource.full_path(f.path) new_resource.updated_by_last_action(f.updated_by_last_action?) end 

但是，当我尝试访问配方中的resource.full_path时，它是nil而不是期望的/path/to/my/resource/relative/path

 # recipes/default.rb resource = my_awesome_lwrp "relative/path" do action :create end log "Full path for my resource: #{resource.full_path}" # outputs "Full path for my resource:" 

我知道这个例子是相当人为的，真实世界的应用程序/原因可以在默认资源/提供者这里看到https://github.com/peterjmit/chef-ssl-cert
