LWRP - attributes required

Chef Infra (archive)
1

Hey All,

Is it possible in the resource file of a LWRP to have attributes required for certain action type.

Exampe:

actions :foo, :bar

default_action :foo

attribute :name, :kind_of => String, :name_attribute => true
attribute :section, :kind_of => String, :required => true (only for :bar action)
attribute :item, :kind_of => String, :required => true (only for :foo action )
attribute :value, :kind_of => [String,Integer], :required => true

Is the :respond_to the right thing?

I tried with no success:

attribute :section, :kind_of => String, :required => true, :respond_to foo?

No, you must do that kind of processing in the provider. The resource
itself does not know what action you may or may not invoke on it
eventually when it is being built.

That is what I figured.

I’ve got a solution that is working in there, but I was wondering if I could do it more elegantly.
