How to customize cron job in ruby application? - ruby

Question

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,

in Sequel 5. Pass the arguments to separate filter methods or use
Sequel.& to combine them.

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)
