Cron function not working

[karthickms]

Hi All,

I use whenever gem but the cron job is not working for me on ubuntu production server. I used following command for every 2 minutes send the mail

02 * * * * /bin/bash -l -c 'cd /root/peatio/current && RAILS_ENV=production && bundle exec rake dailymail:email_sender --silent'

[benlangfeld]

Please define "not working". Without such a definition (include cron logs at least) it is impossible to help you.

Hi,

I have used following code for send mail,
in config/schedule.rb

every 1.hours do
  rake 'dailymail:email_sender'
end

in lib/tasks/dailymail.rake

namespace :dailymail do
  desc "Send email to users"
  task :email_sender => :environment do
  Member.all.each do |members|
    DailyemailMailer.dailymail.deliver
  end
  end
end

in app/mailers/dailyemail_mailer.rb

class DailyemailMailer < ActionMailer::Base
  default from: 'support@tradenaira.com'

  def dailymail(member)
        mail to: member.email, subject: 'TradeNAIRA daily rates update'
  end

end

When I enter the crontab -l in terminal, list out the follows,

# Begin Whenever generated tasks for: /root/peatio/current/config/schedule.rb
0 * * * * /bin/bash -l -c '/usr/local/rbenv/shims/backup perform -t database_backup'

10 20 * * * /bin/bash -l -c 'cd /root/peatio/current && RAILS_ENV=production bundle exec rake solvency:clean solvency:liability_proof --silent'

02 * * * * /bin/bash -l -c 'cd /root/peatio/current && RAILS_ENV=production && bundle exec rake dailymail:email_sender --silent'

# End Whenever generated tasks for: /root/peatio/current/config/schedule.rb

What should I do ?

[benlangfeld]

Please confirm the following:

1. Does the mailer work if you invoke the rake task manually?
2. Do your other two cron jobs run successfully?
3. What is printed in your application log and/or cron log (/var/log/cron.log) at the time the mailer job runs?
4. What happens if you change the schedule to every :hour do?

[karthickms]

1. If I manually enter the "bundle exec rake dailymail:email_sender" in terminal. I got mail.
2. This is a existing application. So I am not sure the above two cron is run or not
3. Sorry I dont know where is cron.log but the cron.log is no on /var/log/
4. Same as working. when i change to every :hour

Please help me.

So I am not sure the above two cron is run or not

Please find out. I can't help you otherwise.

Sorry I dont know where is cron.log but the cron.log is no on /var/log/

What OS are you using? Could you perhaps consult its documentation to find your cron log?

Same as working. when i change to every :hour

I don't understand. It does or does not work? Is there any difference in the generated crontab?

[karthickms]

I am using Ubuntu server.

And when i enter the "whereis cron.log" in terminal

It should be displays :
cron: /usr/sbin/cron /etc/cron.weekly /etc/cron.monthly /etc/cron.d /etc/cron.hourly /etc/cron.daily /usr/share/man/man8/cron.8.gz

It's not working. It is working only when i enter in terminal like the command "bundle exec rake 'dailymail:email_sender'".

[benlangfeld]

You might want to look into explicitly logging your cron jobs and remove the --silent option to get more verbose output. Also try looking in /var/log/syslog for cron output. I also still need to know if the other two jobs work correctly.

Isn't this is code issue?

Looks like,

def dailymail(member) 
  .....
end

accepts member object & you are not passing that one from rake task. Instead having code

Member.all.each do |members|
    DailyemailMailer.dailymail.deliver
end

should be

Member.all.each do |member|
    DailyemailMailer.dailymail(member).deliver
end

Try to look at the logs, you can see the error else execute below on rails console to see the error

DailyemailMailer.dailymail.deliver

Hi @swapnilchincholkar,

Yes. I have missed the code the your pointed out on my second chatting in this loop. But on my code i have correctly do it. Like as

DailyemailMailer.dailymail(member).deliver

[karthickms]

Hi @benlangfeld,

Yes. I am checked on the your specified path /var/log/syslog. In that my cron is displayed. But mail is not receiving

What should I do? Please help me

[karthickms]

Hi All,

I am using following line for that in schedule.rb. It's working fine

env :PATH, ENV['PATH']
env :GEM_PATH, ENV['GEM_PATH']
