Django makemigrations continues to detect removing of translated fields
I'm using django 1.10 and django-modeltranslation. I've removed registrations of translated fields for my models and applied sync_translation_fields management command. But now, everytime I run makemigrations, django produce migrations to remove fields and, although I can fake these, running tests gives errors because migrations try to remove those non existing fields. How to clean up this situation? -
Django 3rd party packages not working
Good day I'm working through a Django projects book called Django by example I am stuck working through the projects because I seem to be having trouble with 3rd party packages, namely taggit and pillow Using pillow as an example..

Prefetching FK objects chain in django for a Model
this question doesn't seem to have an answer since it's a slightly different problem. I have 1 abstract class and 4 concrete models hierarchically organized as below: class LevelAbstract(models.Model): class Meta: abstract = True name = models.CharField('name', max_length=255) class LevelA(LevelAbstract): class Meta(LevelAbstract.Meta): verbose_name = 'Level A' class LevelB(LevelAbstract): parent = models.ForeignKey(LevelA, related_name='children') class Meta(LevelAbstract.Meta): verbose_name = 'Level B' class LevelC(LevelAbstract): parent = models.ForeignKey(LevelB, related_name='children') class Meta(LevelAbstract.Meta): verbose_name = 'Level C' class LevelD(LevelAbstract): parent = models.ForeignKey(LevelC, related_name='children') class Meta(LevelAbstract.Meta): verbose_name = 'Level D' Now I would like to optimize this method in LevelD class that avoid multiple queries: @property def main_level(self): return self.parent.parent.parent I've tried to implement like: @property def main_level(self): self_prefetched_obj = LevelD.objects.select_related('parent', 'parent__parent', 'parent__parent__parent') return self_prefetched_obj.parent.parent.parent I'm not sure if I can call it 'optimization' as it re-fetch self object from DB and I'm wondering if there is any better way (before to take the decision to migrate to django-mptt). Thanks! -

How to use Celery to do asynchronous tasks AWS EC2?
We set up an asynchronous task using Django, celery and rabbitMQ. Here our goal is to perform tasks like video transcoding, Thumbnail generation, Image compression and Image scaling altogether We followed the below tutorial to implement it and the asynchronous task is working properly in Localhost. For the production compatibility, we used supervisord to start celery workers and to restart in case of system reboot or crash. http://michal.karzynski.pl/blog/2014/05/18/setting-up-an-asynchronous-task-queue-for-django-using-celery-redis/ When we tried to implement same in AWS EC2, we are unable to install and configure Supervisord in AWS EC2.so we have to start celery manually every time. Can anyone please help us how to install and how to handle this procedure on AWS EC2 The code we are using task.py from __future__ import absolute_import from test_celery.celery import app import time @app.task def longtime_add(x, y): print 'long time task begins' # sleep 5 seconds time.sleep(5) print 'long time task finished' return x + y celery.py from __future__ import absolute_import, unicode_literals import os from celery import Celery import afnity.settings as settings from django.conf import settings os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'proj.settings') app = Celery('taskapp') app.config_from_object('django.conf:settings') if __name__ == '__main__': app.start() settings.py BROKER_URL = 'amqp://guest:guest@localhost//' CELERY_RESULT_BACKEND = 'redis://%s:%d/%d' % ('localhost', 6379, 0) -

python - Directly Send Files to S3 From Django on Heroku

Efficient way to serve Django REST APIs
APIs built on Django Rest Framework. Few points before my question. I have a Employee model which is linked to seven models with different relationships among themselves. I have a seperate API for employee model I have separate APIs for each of those seven models which uses HyperLinkedModelSerializer. Now for an app calling my APIs has to make 8 requests to get all the information regarding a employee. Is this the REST compliant way to do it? or should I send all the data in a single API using ModelSerializer? or suggest me if there is another way to make the APIs more efficient. -

Save data with current user logged-in Django Admin
So I have this model named Report. It has a column that is linked to User model. And I have set up the authentication of users to be able to add his own report. Obviously, the authentication I've made was to only allow users to add his own report. Since the Report model is linked to User model, he can also select what user to be linked into the report he will add. Is it possible to customize this User field that it will automatically get the current logged user after creating a report? What I've done so far: I've created a dashboard where a user can log in. Created a template for the Report App to be able the user to add their own report. Set the proper authentication for users. What I don't really like about this is I can't find a way to re-use the pop-up add & edit. I found this link but haven't tried it since it seems it's already outdated. -

Two endpoints for the same resource in django rest framework
I want to create two endpoints /comments/ and /comments/requests/ or something to that effect. The first shows your comments, and the second shows your pending comments (Comments that people sent you that you need to approve). They both work with a comments model. How could I achieve this in Django Rest Framework? Right now, my view is class CommentsListview(APIView): serializer_class = CommentSerializer def get(self, request, format=None): comments, _, _, = Comments.get_comment_users(request.user) comments_serializer = CommentSerializer(comments, many=True) return Response({'comments': comments_serializer.data}) def requests(sel,f request, format=None): _, requests, _ = Comments.get_comment_users(request.user) requests_serializer = CommentSerializer(requests, many=True) return Response({'requests': requests_serializer.data}) I'd like to allow a user to go to localhost:8000/comments/ to view their comments and localhost:8000/comments/requests/ to view their pending comment requests. Since I haven't been able to figure this out, the only other sollution would be to require the user to switch the behavior of the endpoint using a parameter as a flag /comments/?requests=True but that just seems sloppy. -
python code for pinging servers in the network and marking unresponsive servers as down
