I am using a delayed job on a Rails 5 project with the 'delayed_job_active_record' gem.
I can't figure out how to check on the status of the job.
I managed to get delayed job to run. The jobs are failing due to an issue with processing uploaded files (that's another issue).
In my controller:
def create
@upload = Upload.create(status: "in progress")
@upload.delay.create_ln(lecture_note_params, current_user, @upload.id)
render json: {"status": @upload.status, "id": @upload.id}, status: 200
end
Here's my model code for the upload model:
class Upload < ApplicationRecord
def create_ln(lecture_note_params, current_user, upload_id)
@lecture_note = LectureNote.new(lecture_note_params.merge(user: current_user))
@lecture_note.upload_id = upload_id
if @lecture_note.save
#nothing
else
logger.info @lecture_note.errors.full_messages.to_sentence
@upload.update(error: @lecture_note.errors.full_messages.to_sentence, status: "error")
end
end
end
The lecture notes don't save. They fail for the reason mentioned above. I need the upload model to update with the error status. How can I do that?
I can see the delayed job in the console :
irb(main):002:0> ap Delayed::Job.last

:updated_at => Thu, 12 Dec 2019 06:11:17 UTC +00:00
}
After the job fails, the "failed_at" field is updated. How can I access that and update my upload model?
Here is the log file while a file is uploading:

OK I found the solution. Tun's answer pointed me in the general direction (very general direction) but led me to it.
delayed_job has callbacks but I didn't know where to put them, or how to use them. They simply go in the model where the job method takes place. That wasn't obvious in the available documentation (to me anyway).
I was looking at this the wrong way. I already have the upload class to manage the creation of the lecture notes. So using the callbacks I can have the job update the class with the status. That's what we needed in the end.
The def failure(job) method did the trick!
I don't 100% understand how these callbacks actually work behind the scenes but they do work.
class Upload < ApplicationRecord
def create_ln(lecture_note_params, current_user, upload_id)
@lecture_note = LectureNote.new(lecture_note_params.merge(user: current_user))
@lecture_note.upload_id = upload_id
# if @lecture_note.save
# #nothing
# else
# logger.info @lecture_note.errors.full_messages.to_sentence
# @upload.update(error: @lecture_note.errors.full_messages.to_sentence, status: "error")
# end
begin
@lecture_note.save
rescue Exception => e
puts @lecture_note.errors.full_messages.to_sentence

def error(job, exception)
puts "Job failed ERROR ------->"
puts @lecture_note.errors.full_messages.to_sentence
self.update(error: @lecture_note.errors.full_messages.to_sentence, status: "error")

# def after(job)
# # Do something useful here
