Django Rest Framework PrimaryKeyRelatedField queryset params
I have this model which has 2 foreign keys: project and registry class Worker(models.Model): project = models.ForeignKey(Project, related_name="workers", on_delete=models.CASCADE) registry = models.ForeignKey(Registry, related_name="workers", on_delete=models.CASCADE) image = models.CharField(max_length=254, null=False) and this serializer showing them: class WorkerSerializer(serializers.ModelSerializer): project = ProjectSerializer(many=False, read_only=True) registry = RegistrySerializer(many=False, read_only=True) registry_id = serializers.PrimaryKeyRelatedField(source='registry', queryset=Registry.objects.all()) class Meta: model = Worker fields = ('id', 'registry_id', 'image', 'project', 'registry') When I browse via the REST api to /projects/1/workers I can see a form asking for image and a dropdown with registries to pick from. The problem is that I don't know how to alter the queryset param in order to fetch registries added by the current user hence the: Registry.objects.all(). I tried by playing with the source param but when I log the queries it still fetches all the registries without any user id being accounted for. Any ideas? -

tzlocal gives me UTC as my local timezone

If I have "2016-11-08 01:25:15" in the database after the created field is populated, when I render my template I expect it to be translated into the local time of the client (I am in eastern time, so I expected it to be "2016-11-07 20:25:15".

Adding a reverse related model on the fly in a django form like in the admin
Let's say for the classical example of an Author has many Books and each Book belong to an Author. When I am adding a book (say using a CreateBookView), I get a select input with authors populated as options. Now, if the author I need is not already there, like in django admin, I need to be able to create the author on the spot, and upon submission, the id and name of the author should be inserted back to the create book form as selected option. I would also like the solution to be easily reusable on other models. What is the best way to tackle this problem? -
Websocket Best Practices for dealing with Human-to-Server interactions
I are implementing some new services in django-channels, using websockets. So far it has been relatively straight forward, and I have multiplexed 6 data streams into one socket. One of the immediate problems I noticed is that the traditional reliable pattern of HTTP connections has been lost. For example, in HTTP land I can fire of a request, and at some point I'll get a response that may contain an error code, a success code, extra data etc. I can then reliably show a success message, an error message etc. to the end user to let them know what is going on. Websockets break this mould. I can send 2 lots of data across to the server, A and B, but I can't be sure of their return value (or even if there is one), nor their return order etc. This represents a new way of thinking-about and handling problems for me (I have only ever done HTTP web stuff before), and I am not sure where to turn. Can someone provide me some resources I can read to understand best practices, including practical examples, for dealing with asynchronous, non-determinate sequences of messages in (web)sockets (and maybe even django-channels) -

How to save inline formset user field in Django using views
I've been using this great post http://kevindias.com/writing/django-class-based-views-multiple-inline-formsets/ to setup my site. I was wondering how to save the user field automatically to an inline formset in views (I used the blockquote for changes to the original).

Serve large dataset w/ Docker, nginx, & django
I am working on a research project that involves large video datasets (100s of GB, possibly multiple TB in the near future). I am fairly new to linux, sysadmin, and setting up servers, so please bear with me. I've provided quite a bit of info, and let me know if there is anything else that would be helpful. I am using Ubuntu, Docker (w/ docker-compose), nginx, Python3.5 & django 1.10 Uploading a large-ish (60GB) dataset leads to the following error: $ sudo docker-compose build postgres uses an image, skipping Building django Step 1 : FROM python:3.5-onbuild # Executing 3 build triggers... Step 1 : COPY requirements.txt /usr/src/app/ ---> Using cache Step 1 : RUN pip install --no-cache-dir -r requirements.txt ---> Using cache Step 1 : COPY . /usr/src/app ERROR: Service 'django' failed to build: Error processing tar file(exit status 1): write /usr/src/app/media/packages/video_3/video/video_3.mkv: no space left on device My files are on a drive with 500GB free, and the current dataset is only ~60GB. I found this discussion on container size. Perhaps I am misunderstanding Docker, but I believe I just want my volumes to be larger, not the containers themselves, so this doesn't seem appropriate. It also doesn't use docker-compose, … -
No module named django error when running any manage.py command in docker with docker-compose
I'm getting ImportError: No module named django when trying to up my containers running docker-compose up. Here's my scenario: Dockerfile FROM python:2.7 ENV PYTHONUNBUFFERED 1 RUN mkdir /code WORKDIR /code ADD requirements.txt /code/ RUN pip install -r requirements.txt ADD . /code/ docker-compose.yml version: '2' services: db: image: postgres web: build: . command: bash -c "python manage.py runserver" volumes: - .:/code expose: - "8000" links: - db:db manage.py import os import sys if __name__ == "__main__": os.environ.setdefault("DJANGO_SETTINGS_MODULE", "myapp.settings") from django.core.management import execute_from_command_line execute_from_command_line(sys.argv) The containers were built successfully My packages are present in the container (I get them when I run pip freeze) I've changed the manage.py content for import django print django.get_version() and it worked. This is basically the same example as in this tutorial, except for starting a new project.
