How to make a redirect after the completion of the execution of the thread (Thread.new)?

Question

Ruby on Rails

Used Thread.new, how to make a redirect after running a task in the background?
Thread.new do
task
sleep 1
redirect_to :root
end
writes "Redirected to" in the console and that's it, nothing happens! how to be?

Answer 1

Thread.new do
...
end.join
redirect_to :root
It just doesn't make sense, the web application thread will still be busy during the execution of the task inside Thread.new
