How to customize cron job in ruby application?

I have been developing a backend with padrino ruby framework and I would like to build a cron job.

This is what I have done.

• gem 'whenever', :require => false
• wheneverize .

inside schedule.rb

 every 1.minute do
    rake "cronjob"
 end

/tasks/cronjob.rake

Here I added my custom tasks. and this will be to long to add here.

So I wrote only error happening parts

performances = Performance.left_join(:slots, id: :slot_id).where(Sequel.~(status: ModelA::Api.settings.pending),Sequel[:slots][:from]>oneweekbefore,Sequel[:slots][:to]<onemonthafter+1.day)
....

begin
  data = {}
  data[:from] = "** <postmaster@**.mailgun.org>"
  data[:to] = email
  data[:subject] = subject
  data[:html] = render 'mails/sendemailbasedontime',:locals => { :data => localdata }
  RestClient.post GigabitArtist::Api.settings.mailgun_domain, data
    rescue => exception
      puts exception.inspect
    end
end

I got these errors:

SEQUEL DEPRECATION WARNING: Passing multiple arguments as filter arguments when not using a conditions specifier ([#:!=, @args=>[:status, "pending"]>, #:>, @args=>[#"slots", @column=>:from>, Sat, 02 Dec 2017]>, #:<, @args=>[#"slots", @column=>:to>, Wed, 10 Jan 2018]>]) is deprecated and will be removed in Sequel 5.

I think errors are from sequel querying and

data[:html] = render 'mails/sendemailbasedontime',:locals => { :data => localdata }

ofcourse, this query was tested in other .rb file and I tested with raw sql. for example, I tested this tasks inside get request hander of test.rb controller. and it does work well I would like to know if I can use render function inside task. I searched all day for this problem with no success. Any advice will be big help for me. Thank you very much.

As the deprecation warning states, you are passing multiple arguments to a filter method. The simplest fix would be to call a filter method separately for each argument:

performances = Performance.
  left_join(:slots, id: :slot_id).
  exclude(status: ModelA::Api.settings.pending).
  where(Sequel[:slots][:from]>oneweekbefore).
  where(Sequel[:slots][:to]<onemonthafter+1.day)
