[chef] Re: data bag API permissions changes in chef server 11

You can specify the exceptions that you're rescuing instead of just blindly trapping all exceptions. What exception do you receive in Chef 11 when trying to retrieve a data bag that might not exist?

You could do something like the following; I'm sure there's a cleaner way but at least you're only attempting to create the new data bag if it doesn't already exist on the server.

databag_name = "sam-config-#{node.chef_environment}"
databag = begin
  Chef::DataBag.load(databag_name)  
rescue Net::HTTPServerException => e
  raise e unless e.response.code == "404"
  Chef::DataBag.new(databag_name)   
end

with chef 10 server and an admin client, I used to be able to create a data bag, then add items to it, like this:

    dbag = "sam-config-#{node.chef_environment}"
    begin
      dbag_bag = Chef::DataBag.new
      dbag_bag.name(dbag)
      dbag_bag.save
    rescue => e
      Chef::Log.info( "Creating the data bag failed: #{e.inspect}" )
    end  

    dbag_item = Chef::DataBagItem.new
    dbag_item.data_bag(dbag)
    Chef::Log.info( "Adding new item: #{id}" )
    dbag_item.raw_data = item
    dbag_item.save

I needed to have the data bag creation in a rescue loop because in 10 server, there was no way without triggering an exception to ask the server if the data bag existed before trying to create it, so I would either get an exception asking if it was there, or I'd get an exception asking to create it.

Now, if it doesn't exist, I get #<Net::HTTPServerException: 405 "Method Not Allowed">

Is there a new way to handle this (or perhaps a better one that works in both chef 10 and chef 11 without blowing up in my face all the time)?

Thanks!
