Accessing extra data passed while calling a celery task
I have task that I'm starting with apply_async such that I can pass extra data. However I'm having trouble accessing this data in the celery signals. For instance this an example of the task, how I'm calling it and task_prerun signal. @task def export_olx(user_id, course_id, language): pass export_olx.apply_async(args=(user_id, course_id, language), kwargs={'some_key':'some_value'}) @task_prerun.connect(sender=export_olx) def export_olx_prerun(sender, **kwargs): pass Inside my task_prerun signal I'm able to access the args using sender.request.args, however when I try using sender.request.kwargs I get an empty dictionary instead of the extra data I passed {'some_key':'some_value'} Any help on how I can access this data will be much appreciated thank you. -
Cant get FCM push notifications from my server on iOS (working on Android)
New to iOS/Swift and cant get push notifications working. I have configured my server backend to push notifications to my app when some action happens. I have configured a data notification trough FCM because I need some custom data in the notification to open one activity/view or another. This is the code used to send the notification (python/django): registration_id = profiletarget.device_token message_title = "Ha llegado tu turno" message_body = "Entra y escribe en el relato para el que estás en cola" data_message = { "title" : "¿Listo para escribir?", "body" : "Ha llegado tu turno para escribir en el relato. Recuerda que tienes un minuto para aceptar tu turno y 3 para escribir.", "bookid" : booktarget.pk, "multimediaurl" : multimediaused.url } result = push_service.notify_single_device(registration_id=registration_id, data_message=data_message) Everything inside this code is working, because I get them correctly on Android. But on iOS... I can't get it working. I have get the notifications token, I have post it to my server, I have use the notification sender on FCM console to send test push notifications (the iphone get them), but not the ones from my custom method, It doesn't show anything. Is anything wrong in the server method or am I missing something? … -
Why generated project.css is not in .gitignore and how to properly solve it?
I generated a project from cookiecutter-django with enabled options: Docker and Gulp. So there is Gulpfile.js, which compiles file sass/project.scss to css/project.css and then minifies it to css/project.min.css. The link to the latter is in HTML. But this min file and generated CSS are not included in .gitignore. The same thing with js (*.min.js is not ignored). I added *.min.js and *.min.css to .gitignore. But what I should do with css/project.css, maybe I should ignore the CSS folder entirely, since I'm using sass? What are the proper solutions in this case? -

Cannot update user profile information

django - re-running migration that creates constraints and fails halfway
I have a migration that adds a bunch of unique_together constraints. When I execute it, it fails halfway because some tables don't respect this constraint. So I have to go in and fix the data, and then run the migration again. Problem is that when I try to run it again, it complains that the constraints already exist django.db.utils.IntegrityError: (1062, "Duplicate entry '406-14933' for key 'app_model_language_id_category_id_29dac763_uniq'") This happens in tables in which there was no problem in the previous run, hence the constraint was created. Then I have to go in and delete the constraint by hand, and then I can run it again. Is there a way to just let it ignore this error and continue? -
