Dynamic Schedule Assignment doesn't work

gistfile1.txt

Following schedule is set on Intialization. config/initializers


jt = ATask.find(:first)
dmt = BTask.find(:first)         
Resque.schedule = {"ASchedule" => {
                                "cron" => "0 */#{jt.hours} * * *",
                                "class" => A,
                                "args" => "",
                                "description" => "Job for A"
                              },
                            "BSchedule" => {
                                "cron" => "#{dmt.run_at_mins} #{dmt.run_at_hrs} * * *",
                                "class" => B,
                                "args" => "",
                                "description" => "Job for B"
                              }
                          }                          

Above is a default schedule. Admin may want to change/update it. An interface is provided to Admin to do that. When Admin does the Schedule update, I execute following code in m controller



        @b.run_at_hrs = params["hrs"].to_i
        @b.run_at_mins = params["mns"].to_i
        @b.save
        Resque.schedule = {
                                    "ASchedule" => {
                                        "cron" => "0 */#{@task.hours} * * *",
                                        "class" => A,
                                        "args" => "",
                                        "description" => "Job for A"
                                      },        
                                    "BSchedule" => {
                                        "cron" => "#{@b.run_at_mins} #{@b.run_at_hrs} * * *",
                                        "class" => B,
                                        "args" => "",
                                        "description" => "Job for B"
                                      }
                                  }
