Django template: How to use values/values_list
In template I am trying to do something like this: {{ request.user.profile.following.all.values_list }} and I get <QuerySet [(7, 2, 1)]> , but I want to get <QuerySet [2]> like in Django values_list. For example: Follow.objects.filter(follow_by=self.request.user.profile).values_list('follow_to', flat=True) Can I pass argument like this in template? -
How to make Django 3, channels and uvicorn work together
I have been trying to switch from daphne to uvicorn for production with a project using django 3 and channels. I have been encountering errors while loading the classical asgi file for channels. Either I can't use it due to synchronous call to django.setup or get_application. I tried to tweak this file with the sync_to_async call without success. Has anyone managed to make it work ? Original asgi.py Code import os import django from channels.routing import get_default_application os.environ.setdefault("DJANGO_SETTINGS_MODULE", "config.settings") django.setup() application = get_default_application() StackTrace Traceback (most recent call last): File "/usr/local/lib/python3.8/multiprocessing/process.py", line 315, in _bootstrap self.run() File "/usr/local/lib/python3.8/multiprocessing/process.py", line 108, in run self._target(*self._args, **self._kwargs) File "/var/www/.cache/pypoetry/virtualenvs/project-4ffvdAoS-py3.8/lib/python3.8/site-packages/uvicorn/subprocess.py", line 61, in subprocess_started target(sockets=sockets) File "/var/www/.cache/pypoetry/virtualenvs/project-4ffvdAoS-py3.8/lib/python3.8/site-packages/uvicorn/main.py", line 407, in run loop.run_until_complete(self.serve(sockets=sockets)) File "/usr/local/lib/python3.8/asyncio/base_events.py", line 612, in run_until_complete return future.result() File "/var/www/.cache/pypoetry/virtualenvs/project-4ffvdAoS-py3.8/lib/python3.8/site-packages/uvicorn/main.py", line 414, in serve config.load() File "/var/www/.cache/pypoetry/virtualenvs/project-4ffvdAoS-py3.8/lib/python3.8/site-packages/uvicorn/config.py", line 300, in load self.loaded_app = import_from_string(self.app) File "/var/www/.cache/pypoetry/virtualenvs/project-4ffvdAoS-py3.8/lib/python3.8/site-packages/uvicorn/importer.py", line 20, in import_from_string module = importlib.import_module(module_str) File "/usr/local/lib/python3.8/importlib/__init__.py", line 127, in import_module return _bootstrap._gcd_import(name[level:], package, level) File "<frozen importlib._bootstrap>", line 1014, in _gcd_import File "<frozen importlib._bootstrap>", line 991, in _find_and_load File "<frozen importlib._bootstrap>", line 975, in _find_and_load_unlocked File "<frozen importlib._bootstrap>", line 671, in _load_unlocked File "<frozen importlib._bootstrap_external>", line 783, in exec_module File "<frozen importlib._bootstrap>", line … -

Django: Identical text not unique on binary level
I have a modal with a field my_field which has to be unique. I´ll check if a task has to be executed later onwards by checking if the entity already exists: class MyModel(models.Model): my_field = models.CharField(max_length=75, unique=True) And later: if MyModel.objects.filter(my_field=my_value).exists(): pass # execute task and save it under the value name in question else: pass The values I need to compare here are received via two different 3rd party apis. Now I have the problem, that the "human readable" same text is not detected as identical, which makes the unique attribute fail (in the sense of it does not let the save fail) and of course also the "does it exist? check". So after a while, I hacked into django shell and converted two of the values into binary code and that way they are not the same. So I read about normalization and came up with this: class MyModel(models.Model): ... def save(self, *args, **kwargs): if self.pk is None: self.my_field = unicodedata.normalize('NFC', self.my_field) ... And before I query the DB, I normalize the received value the same way. Still I get instances with the same "human readable text" but different binary code and the problem persists. How can I … -
Django: How to decide between class-based and function-based custom validators?
This is a beginner question. I'm working on a website that allows users to upload a video to a project model (via ModelForm) and I want to validate this file correctly. I originally declared the field in this way: from django.db import models from django.core.validators import FileExtensionValidator def user_directory_path(instance, filename): """ Code to return the path """ class Project(models.Model): """ """ # ...Some model fields... # Right now I'm only validating and testing with .mp4 files. video_file = models.FileField( upload_to=user_directory_path, validators=[FileExtensionValidator(allowed_extensions=['mp4'])] ) But I read in several places that it was better to use libmagic to check the file's magic numbers and make sure its contents match the extension and the MIME type. I'm very new to this, so I might get some things wrong. I followed the validators reference to write a custom validator that uses magic. The documentation also talks about "a class with a __cal__() method," and the most upvoted answer here uses a class-based validator. The documentation says that this can be done "for more complex or configurable validators," but I haven't understood what would be a specific example of that and if my function-based validator is just enough for what I'm trying to do. I … -
Reaching the fields in the data serialized over the table

DjangoLoop through an app urls in template
I'm django beginner working on my third project, but running into small issue. Basically, i have an app called 'projects' which contains html templates that the CBV needs for CreaeView, UpdateView, DeleteView and ListView. My base templates inherits from a menus file which contains all the navigation menus needed for the website. Now my issue is i wanted to make projects menu active (css) for all the crud operations of project app. i did this and it's working as intended: {% url 'projects-list' as url %} {% url 'project-detail' project.pk as url1 %} {% url 'project-create' as url2 %} {% url 'project-update' project.pk as url2 %} <a href="{{ url }}" {% if request.path == url or request.path == url1 or request.path == url2 or request.path == url3 %} class="item active" {% endif %}><span class="icon"><i class="fa fa-folder-o"></i></span><span class="name">Projects</span></a> But i don't like it this way as it's too repetitive and i want to add a lot of menus like this in future. What is the easiest way to loop through all links of app? Thanks in advance. Best regards. -

Developing filtering api for the fields of two models which has many to one relationship (ie one model has a foriegn key field) using djangofilterset
Its not a problem for making a filterset for a single model. But I have two models and I have to make an endpoint http://127.0.0.1:8000/api/activities/?destination=Dubai&title=Surfing like this.

How to set virtualenv to stay active on a host server
I created a website that uses vuejs as the frontend and django as the backend with another service running behind everything that im making api calls to. So django is setup in a way to look at the dist folder of Vuejs and serve it if you run manage.py runserver. but the problem is that my service that I created is in python and it needs to run in a virtualenv in order to work (It uses tensorflow 1.15.2 and this can only run in a contained environment) I'm sitting here and wondering how I can deploy the django application and keep the virtualenv active and Im coming up with nothing, I've tried doing some research on this but everything I found was not relevant to my problem. I've deployed it and when I close the ssh connection the virtualenv stops. If there is anyone that can enlighten my ways I would appreciate it. -

What happens when Django Session timesout?
In my scenario the function which does some backend updates is called when request is submitted takes a lot of time to return the value and as a result the session times out.
