Rails for Beginners Part 36: Background Jobs with Sidekiq Discussion

I had to change the timezone in config/application.rb. Rails default's timezone is UTC + 0 and my own timezone is UTC + 1. So at 8:00pm when I was trying to publish at 8:01pm, Time.current was returning 7:01pm and the guard clause "return if tweet.publish_at > Time.current" was therefore always true. Is there an easy way to manage multiple timezones ? I guess it is fine to have a timezone set in application.rb if all users are in the same timezone but background jobs would not work properly everytime a user would be in another timezone, right?

At 1:46 of the video you have a screen full of issues, as while I followed the directions it says there is an undefined method 'published?' for nil:NilClass"

I backed out sidekiq and tried to run on the activejobs and it worked fine, so it seems to be something with SideKiq which also claims some sort of issue with a gem called racc which i did install (didn't have it) and still claims an issue with older version even though I'm running newer version

Anyone run into the same issue?

For linux I installed only redis , and start the redis manually, then rails s and then sidekiq

Linux / Ubuntu 20
If anyone has a problem when everything is started: Redis-> Sidekiq -> Rails Server and Sidekiq is doing nothing - no changes in the console - no posted tweet.

Create a file in config/initializers/sidekiq.rb
Copy/Paste inside and save:

Sidekiq.configure_server do |config|
  config.redis = { url: 'redis://localhost:6379/0' }
end

Sidekiq.configure_client do |config|
  config.redis = { url: 'redis://localhost:6379/0' }

Restart everything and run again.

Let me know if it does work for you.

there is any way to install redis in windows like newest versions because i have file contain redis 3.2.0 which is useless with new version of sidekiq
??????

I'm running WSL and I ran into this issue with sidekiq

To get past this error, just run bundle exec sidekiq

Everything runs properly but the tweet is not posted. I have started redis, sidekiq and changed my timezone.
Can anyone help me?

sudo apt-get install redis-server

Is what I had to use to install in linux

My tweets don't publish on their scheduled date & time. Can anyone please help me with this issue? Everything else seems fine - this is the only issue i'm facing.
