[chef] Re: Converting node attributes to yaml

[Curtis Stewart < >]

I just found a solution (at least temporarily) in case someone is interested.

Here’s my helper method:

def attributes_to_yaml
  hash = node[‘app'][‘config'].to_hash
  mutable_hash = JSON.parse(hash.dup.to_json)
  mutable_hash.to_yaml
end

I’m trying to allow a settings.yml file to be generated from node attributes.

I assumed the following would work, but I’m left with various 
“!ruby/hash:Chef::Node::ImmutableMash” lines in my yaml file.

YAML::dump(node[‘applications']['settings'].to_hash)

settings: !ruby/hash:Chef::Node::ImmutableMash
foo: !ruby/array:Chef::Node::ImmutableArray
- settingone
bar: !ruby/array:Chef::Node::ImmutableArray
- settingone

I’d like to be able to allow for a very flexible configuration, however, 
maybe this is just a bad practice and I should use a template with a smaller 
number of configurations?

Thanks,

There’s a patch to make to_hash convert ImmutableMash to regular Hashes, but 
it doesn’t correctly handle some cases of nested structures, like an Array of 
Hashes. It’d be great if you could fix it up: 
https://tickets.opscode.com/browse/CHEF-3953

If that’s beyond the work you’re willing to do, there’s at least some 
monkey-patch type workarounds to be found in that and related tickets (though 
monkey patches are inherently brittle and can be accidentally broken in minor 
or possibly patch releases, so beware).
