Ruby - undefined method `map' for string-CodePudding

I'm unable to convert array of string to integer. I'm getting the following error undefined method map for "[\"118\", \"119\"]":String.

Any idea how to resolve this?

            def job_template_by_id
              job_template_id = var_search(@handle.object, 'job_template_id') ||
                                var_search(@handle.object, 'dialog_job_template_id')
                               
              job_template_id = job_template_id.map(&:to_i)

              @handle.vmdb(SCRIPT_CLASS).where(:id => job_template_id) if job_template_id
            end

Error:

CodePudding user response：

Well, that error says that it's not an array which you expect, it's a string, probably JSON. so you need to parse it firstly

job_template_id = JSON.parse(job_template_id).map(&:to_i)
