How to Import Django Static File with Dynamic Name using Regex
I'm building a SPA with Django and React, but I'm relatively new to Django and can't find info on importing a static file with a dynamic name using regex. The static file is a webpack bundle in the format 'main-[hash].js' - examples: main-92e041e445bf7b737036.js and main-3583de2c3fcf00501624. Also, I realize that I can change webpack to generate bundles with static names, but that'd be no fun. -
There will get cross-domain issue when I deploy the frontend and django backend to remote server
Deploy the test environment to remote server. I use python manage.py to run the development server for django backend: python manage.py runserver 8001 and use the apache to listen the 80 port for website frontend. So, when website request the backend, there is cross-domain issue, because the port is not same. How to handle this issue correctly if in the development environment? Or if this is impossible, whether only can use distribution environment to realize it? -
Django Change Date Format from YYYY-MM-DD HH:MM to MM/DD/YYYY
I'm trying to pass input from a template to a query in my view, but if the date is not passed in Django's default date format YYYY-MM-DD then it throws an error. [u"'11/11/2012' value has an invalid format. It must be in YYYY-MM-DD HH:MM[:ss[.uuuuuu]][TZ] format."] template.html <form method="GET" action="/BusComm/interactions"> <div style="width: 100px; float:left"> <p>To Date:</p> </div> <div style="width: 200px; float:left"> <input type="date" Placeholder="mm-dd-yyyy" name="date_to" id="id_q" value="{{ query }}" float="right"> </div> <input type="submit" value="Submit" /> </form> View.py def interactions(request): today = datetime.now().date() table = interactionsTable(Interactions.objects.all()) if request.GET.get('date_from'): date_from = request.GET.get('date_from') table = interactionsTable(Interactions.objects.filter(date__range=[date_from, today])) return render(request, 'BusComm/interactions.html',{ 'table': table, }) The interactionsTable(Interactions.object.filter()) line is the one that throws the error. My question is how can I change the date format in Django to accept MM/DD/YYYY instead of YYYY-DD-MM? -

Run a Django project from VSCODE
Is there a way to run a Django project from VSCODE editor? Currently I use the windows CMD to run my project. Every time when I hit the button 'run' on VSCODE it doesn't run the project. On pyCharm we can add 'runserver' to its script parameters configurations. Is there something like that on VSCODE? Thanks. -

Django app in heroku deleting model objects after some time
I've written a simple django Q&A forum app and deployed it on Heroku, the local version of the site works fine. However, the production version does not store the questions, answers etc. for more than a few hours. I decided to stick with sqlite3 that comes with Django. I don't expect a lot of traffic to the site so I decided it would be worth it to keep the development db for now. site: http://immense-plateau-35286.herokuapp.com I've tried a few solutions from the DB setup page on Heroku, but have not had any success so far. Any idea what this might be? -
Unable to get data from django choice form

IntegrityError: null value in column "id" for all models/fields with ForeignKey after postgres restore from dump
I'm running into issues trying to use a heroku postgres datastore from a restore of a local postgres database I have. Using the restored postgres database Django runs as normal. It retrieves all objects and uses their fields, primay key's etc without any issues. But when it comes to writing to the database, I get the same error across the board, regardless of the model(s). If it has any field that is a relationship field, I will get this error: psycopg2.IntegrityError: null value in column "id" violates not-null constraint The relationship object(s) are being passed into the .save(), .add() methods etc. and work JUST fine locally. But using this restored database, it throws this IntegrityError as if all objects in the database have null id's. I can't find anything anywhere online with a similar problem to go off of. When I reset the heroku database and create objects from a blank slate there are no problems. But if I try to do this with the restored copy, I always get this null value in column "id" violates not-null constraint .. but the object(s) WAS/WERE passed in and DID have a primary key(s)! I'm not passing in Null values, which in … -

Retrieve a filtered ForeignKey with Django

Webpack unnable to bundle due to SyntaxError
I was interested in learning Django + ReactJS on Windows, so I followed this step by step tutorial. Now, I'm on the bundling stage. When I run my bundler as a quick sanity check: $ node_modules/.bin/webpack --config webpack.dev.config.js I got node_modules is not recognized as a windows command. After trying different solutions, I found that using the node command in front of the webpack command was executing webpack.

Django Rest Framework: get_FOO_display in serializer not letting me POST
I recently added a source='get_fieldname_display to my serializer. It worked perfectly for the purpose of obtaining the display value of a choices tuple but now I can no longer POST data using the API end point without getting an error: TypeError: 'get_fieldname_display' is an invalid keyword argument for this function To be clear, the addition to the serializer was this line specifically: fieldName = serializers.CharField(source='fieldName_display') I know that this line is causing the problem because when I comment it out, I can POST data without a problem. However, I need this line in there so I may obtain the display names from the choices tuple when I am GETting data. I think the problem may be remedied if I use two different serializers, one for GET and another for POST, but I am not sure how to go about doing this--I am using a generics.ListCreateAPIView in my views.py. -

Django-Rest-Auth Reset Password via email
I'm attempting to implement a Forgot Password button, utilizing the url /rest_auth/pasword/reset. My assumption, from reading the docs on this endpoint, is that you only need to pass an email to the endpoint, and then the reset email will be sent, prompting the user to reset their password. The issue is, this flow only works when the user is actually logged in, thus when the session has a valid token key to send back to the server. If the user forgets their password, they obviously won't be logged in, and thus won't have a token to send back to the server. This is the error I get when trying to post to the endpoint with just the email and no token header. {"detail":"Invalid token header. No credentials provided."} I didn't think that we should need to include a token in the header because that defeats the purpose. Am I misunderstanding how this endpoint is supposed to be used? -
Django seems to be using incorrect settings module
Something strange has happened in my django app and I can't seem to trace it back to a particular change. Whenever I run python manage.py runserver, I get this error: CommandError: You must set settings.ALLOWED_HOSTS if DEBUG is False. My settings module is configured properly -- I have DEBUG=True and I have also set ALLOWED_HOSTS. I continued to investigate and it seems like somehow, Django has decided to import the wrong settings module. When I do from django.conf import settings and I print settings.__dict__, I see this: {'LANGUAGE_CODE': 'en-us', 'LOGGING': {}, 'DEBUG': False, 'USE_I18N': True, 'INSTALLED_APPS': ('django_nose',), 'FORCE_SCRIPT_NAME': None, 'LOGGING_CONFIG': 'logging.config.dictConfig', '_wrapped': <Settings "django.conf.global_settings">} It seems like DJANGO_SETTINGS_MODULE is somehow being set to django.conf.global_settings. I've tried to override this by settings os.environ['DJANGO_SETTINGS_MODULE'] explicitly in manage.py, but this doesn't seem to fix anything (though the env. variable does appear to be set properly after this). However, I still get the same bizarre value for my settings file. I've also tried uninstalling django-nose, thinking that this might be the culprit (as it seems to be the only app installed in this bizarre settings file). But that didn't seem to change anything. -
Django Commenting system
I'm making an answering/commenting system for my post's. And here's how the models.py looks: from django.conf import settings from django.core.urlresolvers import reverse from django.db import models from django.utils import timezone import misaka from groups.models import Group from django.contrib.auth import get_user_model User = get_user_model() class Post(models.Model): user = models.ForeignKey(User, related_name="posts") created_at = models.DateTimeField(auto_now=True) message = models.TextField() message_html = models.TextField(editable=False) group = models.ForeignKey(Group, related_name="posts",null=True, blank=True) def __str__(self): return self.message def save(self, *args, **kwargs): self.message_html = misaka.html(self.message) super().save(*args, **kwargs) def get_absolute_url(self): return reverse( "posts:single", kwargs={ "username": self.user.username, "pk": self.pk } ) class Meta: ordering = ["-created_at"] unique_together = ["user", "message"] class Answer(models.Model): post = models.ForeignKey('posts.Post', related_name='posts') author = models.ForeignKey(User, related_name='answers') answer = models.TextField() create_date = models.DateTimeField(default=timezone.now) published_date = models.DateTimeField(blank=True, null=True) def __str__(self): return self.answer def get_absolute_url(self): return reverse('post_detail', kwargs={ "username": self.user.username, "pk": self.pk, }) I've been having a problem, with basically showing the answers/comment's in the post detail.

Slow database operation Django filter
I have to filter through a model that has around 24 mil. instances (records). I need to filter them based on some name got from the url kwarg, I have something like this: Model.objects.filter(field__icontains=self.kwargs['kwarg']).values() on a view. This is absolutely not efficient since the page is really slow and takes a lot of proccessing from the CPU. How can I solve this issue? Thanks in advance for answers! -
Django's HttpResponseRedirect not visible by proxy system
I have Django web application and route all requests to this web app via reverse proxy (Netflix Zuul). One of view classes in Django returns HttpResponseRedirect("/"), but this redirect does not visible by routing system (by Netflix Zuul). Is it possible somehow to setup Django web app so all redirections (status codes 301 and 302) will be visible by proxy system? Or should I setup routing system for that? Please explain this behavior. Reproduction steps I launched Django web app on localhost:8000. When in browser I want to point to view class that has redirection: "localhost:8000/list", then browser's developer tool displays two requests: first with status code 302 and second with 200, and after redirection link looks like "localhost:8000/". first request: * Request URL:http://localhost:8000/list * Request Method:GET * Status Code:302 FOUND * Remote Address:127.0.0.1:8000 and response headers contain: Location:http://localhost:8000/ second request: * Request URL:http://localhost:8000/ * Request Method:GET * Status Code:200 OK * Remote Address:127.0.0.1:8000 After that I applied proxy system and launched it on localhost:8080 (routing redirects all requests to localhost:8000). When searching in browser by "localhost:8080/list", browser's developer tool displays only a single request and still stays on the same link (but I need link changed to "localhost:8080/") * …
