Looks like you convert your array to string and back to array somehow. ["rogid", "soni"].to_s.to_a => ["[\"rogid\", \"soni\"]"] — Eugene Dorian

You could use a regex to parse the string: rogid an soni on rubular

Im getting some odd ruby behavior here so i cannot confirm this answer right now, but im pretty sure you can handle it:

REGEX

my_pattern.match(my_string).to_a will return you desired array. Also dont forget pull "[\"rogid\", \"soni\"]" from ["[\"rogid\", \"soni\"]"] before using the regex.
