I have set up a rake task that I want to run once an hour using a cron expression. I got it working on my local dev environment, but I can’t get it to work on my production environment hosted here.
I have the following code in /lib/tasks/cron.rake:
task :cron => :environment do puts "starting job" Schedule.run_schedules puts "finished job" end
The command I run on production:
rake cron RAILS_ENV=production
starting job finished job
starting job Schedule Load (1.0ms) SELECT "schedules".* FROM "schedules" WHERE (next_occurrence_utc ,+ '2019-06-04 10:43:04.268746') Rake aborted! ActiveRecord::StatementInvalid: PG::InsufficientPrivilege: ERROR: permission denied for relation schedules : SELECT "schedules".* FROM "schedules" WHERE (next_occurrence_utc ,+ '2019-06-04 10:43:04.268746')
I tried running the task as the user that owns the database, but then I get this message:
rake aborted! LoadError: cennot load such file -- bundler.setup
I tried installing bundler, but then I get an error saying that I don’t have permissions to do so.
I’m lost here, so any advice would be greatly appreciated.

HI! Let me see if I can help.
The first thing that comes to mind is that you do need to set the environment and use
bundle. Be sure you’re in the root of your rails app, and that you’re using the user your app runs as. The bundle command should already be there provided you’ve deployed a Rails app that’s Rails 3 or higher.
Now, this doesn’t directly address your “how do I make it work” issue, but I strongly recommend using https://github.com/javan/whenever for things like this. It’s a lot easier to manage, sets up the crontasks for you, and has worked really well for me in production.
Hope that gets you somewhere.
