Use the built in CSV class in Ruby's standard library: http://www.ruby-doc.org/stdlib-2.0.0/libdoc/csv/rdoc/

irb(main):020:0> require 'csv'

=> true

irb(main):021:0> CSV.parse_line("\"acc1\",\"acc2\"")

=> ["acc1", "acc2"]

Thanks Josiah,

what is it i have to do to make it an array of strings ? the values are comma separated so its an array essentially.

Thanks

No, it's definitely a string you're assigning, not an array.

# #split returns an array of strings. #last returns the last string in the array. deploy is currently a string

deploy = line.split(':').last

# You are doing a gsub on a string, so deploy is still a string. As an aside, you could use #gsub! here to avoid the extra assignment.

deploy = deploy.gsub(/\n/," ")

# node['account_deploy'] is being assigned to deploy which is a string

node.set['account_deploy']=deploy

What is unclear? The string happens to be %q["acc1","acc2"], which looks like an array in the logs, but you can see in your logs that the " are escaped, so you do in fact have a string.

Thanks Doug, 

but i see the value of the node attribute though in the logs ,

Chef Client failed. 0 resources updated

looks like its getting the value but not treating it as an array of strings or something.

Thanks

That doesn't work because the ruby_block's block doesn't execute until
converge time and the loop you have there that is outside of the
ruby_block runs at compile time.
