I wrote a rake task which executes from command line and not from cronjob

Question

I wrote a rake task which executes from command line and not from cronjob.

I wrote a task which internally calls model method, so suppose my task name is dataimport so if I call as

rake db:dataimport

it works, and create records in database. But when I want execute it for every 10 seconds I putin crontab as

* * * * * sleep 10; cd $APP_DIR/lib/tasks; rake db:dataimport

this doesn't work.Any suggestions on this.

Where can I see errors, as this is `cronjob`, which is executing code from rake task. errors are not getting logged in `production.log` — Sonalkumar sute, Jul 15 '15 at 10:58
What about `grep CRON /var/log/syslog` ? Have you see something about you task? Cronjob do not post the result of job to the rails logs, you should look at system logs. — Roman Kiselenko, Jul 15 '15 at 11:02
yes done that, `Jul 15 13:03:01 app-ded-1 /USR/SBIN/CRON[13217]: (app) CMD (sleep 10; cd $APP_DIR/lib/tasks; rake db:dataimport)`, it shows something like this with many lines, no errors — Sonalkumar sute, Jul 15 '15 at 11:05
I suggest you read [`debugging crontab`](http://stackoverflow.com/questions/4883069/debugging-crontab) this article can help you to resolve issue. — Roman Kiselenko, Jul 15 '15 at 11:07
It could be an environment issue. Do you use something like rvm or rbenv? — ihaztehcodez, Jul 15 '15 at 11:29
@ihaztehcodez I am not using any of them, it's ruby directly — Sonalkumar sute, Jul 15 '15 at 12:50

For rake commands to execute, you need to set PATH variable in your crontab file

If you are using ubuntu linux then first execute 'crontab -e' command and then add the following line

PATH=/bin:/sbin:/usr/bin:/usr/sbin:/usr/local/bin:/usr/local/sbin

at the top of the file.
