Rails ActiveJob Starting with a Controller

I have my own code that calls some backend systems and updates the database remotely. I have an ActiveJob that does a task:

## Runs join code
class DataJoin < ApplicationJob
  queue_as :default

  def perform
    join = Joiner.new
    join.run
    NotifMailer.sample_email.deliver_now
  end
end

I want to start an ActiveJob manually from a controller / view:

class AdminController < ApplicationController
  before_action :verify_is_admin

  private def verify_is_admin
      (current_user.nil?) ? redirect_to(root_path) : (redirect_to(root_path) unless current_user.admin?)
  end

  def index
    @username = current_user.name
    @intro = "Welcome to the admin console"
  end

  def join
   ## Code to start ActiveJob DataJoin??
  end
end

How can I launch an ActiveJob from a controller?

Try the following:

DataJoin.perform_later


perform_later

specifies the job in the specified queue. If perform

your active job method accepts some arguments, you can even pass them in perform_later

and they will be available at runtime.

DataJoin.perform_later(1, 2, 3)

# DataJoin
def perform(a1, a2, a3)
  # a1 will be 1
  # a2 will be 2
  # a3 will be 3
end
