Allauth returns 500 when in production
I am having some trouble with my Django 1.8.14 application in combination with allauth 0.27. Whenever I deploy my application and try to authenticate with wrong credentials, I get a 500 error. This doesn't happen when I run my application locally. I have a django.contrib.sites.models.Site instance with id=SITE_ID so I can't really figure what is going wrong.

Get all objects from severall models that share the same foreign key - Is it possible?
I am facing a problem designing a database with Django framework that i can't seem to solve. Say i have the following models: class ModelA(models.Models): field1 = ..... field2 = ..... class ModelB(models.Model): fieldA = models.ForeignKey(ModelA) ... class ModelC(models.Model): fieldA = models.ForeignKey(ModelA) ... class ModelD(models.Model): fieldA = models.ForeignKey(ModelA) ... My question is: Is it possible to get all objects from Models B, C and D that share the same oject from ModelA? I do not wish to query each model (B, C or D) individually because in reality i have many more models. Any help is much apreciated. -
Django Rest Framework Many to Many field related to itself
I have an AngularJS project that used Django as a framework through the Django Rest Framework (DRF). I've created a Group model and set up a serializer class for it, however I want to now establish a new field on that model called related_groups, which would reference the same model (Group) as an array of primary keys. I don't know if it's possible to self-reference in the serializer, though, and I don't know how else to pass through related groups from the front-end, which can be picked and chosen by the users who own the group. class GroupSerializer(serializers.ModelSerializer): class Meta: model = mod.Group fields = ( 'group_id', 'group_name', 'category', 'related_groups', ) and the representation appears to be exactly what I want: GroupSerializer(): group_id = IntegerField(read_only=True) group_name = CharField(max_length=100) category = CharField(max_length=256, required=False) related_groups = PrimaryKeyRelatedField(many=True, queryset=Group.objects.all(), required=False) I'm not getting any errors on save, but I'm also not getting the values into my DB. Am I able to represent many-to-many relationships from a model back to itself with DRF? Or do I need to have another serializer just for the relationship table? The documentation for DRF doesn't use self-referential models, so I wonder if it's a poor design choice. -

In Django, how do I update a user profile if a model is added to database?
I'm creating a site where users can upload files. I have my upload form working, and it correctly associates the current user with the uploaded file. Once it's uploaded however, I would like the User Profile model to update the number of files uploaded for that specific user. I'm using django-allauth with a custom admin model. models.py (works to recognize current user) class ConfigFiles(models.Model): user = models.ForeignKey( settings.AUTH_USER_MODEL, blank=True, null=True) Printer = models.CharField(_('Printer Model'), max_length=100, blank=True, null=True, unique=False, help_text="Something like 'i3'") printerbrand = models.CharField(_('Printer Brand'), max_length=100, blank=True, null=True, unique=False, help_text="Something like 'Prusa'") Plastic = models.CharField(_('Plastic'), max_length=40, blank=True, null=True, unique=False, help_text="Something like 'ABS' or 'Nylon'") HDConfig = models.FileField(_('High Detail, Slow Speed'), upload_to=UploadedConfigPath, validators=[validate_file_extension], help_text="Displayed as HD on Infinity-Box") LDConfig = models.FileField(_('Fast speed, Low Detail'), upload_to=UploadedConfigLDPath, validators=[validate_file_extension], help_text="Displayed as FAST on Infinity-Box") pub_date = models.DateTimeField(_('date_joined'), default=timezone.now) And here's my custom admin models.py (doesn't auto update configuploaded) class UserProfile(models.Model): user = models.OneToOneField(DemoUser, primary_key=True, verbose_name='user', related_name='profile') avatar_url = models.CharField(max_length=256, blank=True, null=True) configuploaded = models.IntegerField(_('Number of uploaded Config files'), default=0, unique=False) filesuploaded = models.IntegerField(_('Number of uploaded STL files'), default=0, unique=False) dob=models.DateField(verbose_name="dob", blank=True, null=True) def __str__(self): return force_text(self.user.email) class Meta(): db_table = 'user_profile' Ideally, whenever the user uploads a file the configuploaded variable increase correspondingly.

Can request.user be False while request.user.is_authenticated is True?
A snippet out of Django Rest Framework: class IsAuthenticated(BasePermission): def has_permission(self, request, view): return request.user and is_authenticated(request.user) def is_authenticated(user): if django.VERSION < (1, 10): return user.is_authenticated() return user.is_authenticated Is there a practical and relevant case where my own code would return unexpected or different results from the above? class IsAuthenticated(BasePermission): def has_permission(self, request, view): return request.user.is_authenticated -
Why is a auto_now=True field designed to not update when using QuerySet.update()?
from django: The field is only automatically updated when calling Model.save(). The field isn’t updated when making updates to other fields in other ways such as QuerySet.update(), though you can specify a custom value for the field in an update like that. Both will have to execute an update query, so what is the reason behind save.() updating the auto_now=True field and QuerySet.update() not updating the field? -
Angular Routing in Django
I am new to Angular JS and trying to implement routing in a Django App. My Html code is:- <body> <nav class="navbar navbar-inverse" ng-app="QuizRouting"> <div class="container-fluid"> <div class="navbar-header"> <a class="navbar-brand" href="#">WebSiteName</a> </div> <ul class="nav navbar-nav"> <li class="active"><a href="#">Home</a></li> <li><a href="#/page1">Page 1</a></li> <li><a href="#">Page 2</a></li> <li><a href="#">Page 3</a></li> </ul> </div> </nav> <div ng-view></div> </body> My JS code is :- var app = angular.module('QuizRouting',['ngRoute']); app.config(function($routeProvider) { $routeProvider .when("quiz/page1", { templateUrl: "/quiz/templates/quiz/page1.html" }); }); I have included all the prerequisites for Angular and angular routing.

Django - Group by column and where on a different column
Problem statement These are my django models: class Status(models.Model): status = models.CharField(max_length=20) class Project(models.Model): client = models.ForiegnKey(Client) class TicketRequest(models.Model): status = models.ForiegnKey(Status, related_name='ticket_requests') project = models.ForiegnKey(Project) created = models.DateTimeField() Required result status.value | client.id | count --------------+-------------+--------- is_assigned | 4 | 2 is_closed | 4 | 66 is_open | 4 | 7 Solutions tried 1. Querying the Status model Status.objects.filter( ticket_requests__project__client_id=4 ).values('value').annotate( count=Count('ticket_requests__project__client') ) This returns the following data: [{'count': 2, 'value': u'is_assigned'}, {'count': 66, 'value': u'is_closed'}, {'count': 7, 'value': u'is_open'}] which is perfect! But I need to filter the queryset on TicketRequest.createdwith filters such as today, this week and month. These filters need to be reused a lot, so I created a handy helper. Shortened for brevity def qs_time_range(qs, time_range, field_name): now = timezone.now() if time_range == 'month': past = now - timedelta(days=30) return qs.filter( **{field_name + '__date__range': [past, now]} ) Problem When I use the helper to filter the ticket requests, the results are not what I expect. filters.qs_time_range( Status.objects.filter(ticket_requests__project__client_id=1), 'month', 'ticket_requests__created' ).values('value').annotate( count=Count('ticket_requests__project__client') ) Result [{'count': 27, 'value': u'is_assigned'}] When instead this should be the result: value | count -------------+------- is_assigned | 3 is_closed | 3 is_open | 3 (3 rows) -

Can I disable delete() in django-rest-famework by not calling object.delete()
I have a pattern that I use: class View(generics.RetrieveUpdateDestroyAPIView): ... def delete(self, request, pk): if cantDelete(): return JsonResponse({ 'success' : False, 'message': "Can't delete this"}) self.get_object().delete() return JsonResponse({ 'success' : True, 'message': "Deleted"}) I have a reason to believe that the objects are sometimes being deleted if cantDelete() is true. Is this a bad pattern? Can't I disable delete() in this way? I will do some experiments, but it's a production back end and a bit of an emergency, so if anyone can chime in with an answer before I get a chance to post an answer myself, it would be much appreciated. -
Override django admin change_list with multiple admin sites not working
I've exposed multiple databases in the admin site using the link here: django-docs.

Setting up WebSockets with Django Channels on AWS Elastic Beanstalk
I'm trying to set up WebSockets on AWS instance. Since I use Django for my webapp, for WebSocket support I use Django Channels. I deployed the app using AWS Elastic Beanstalk, but I get the error: WebSocket connection to 'ws://xxx.elasticbeanstalk.com/' failed: Error during WebSocket handshake: Unexpected response code: 200. After some research I found that I need to set up TCP on port 80 and SSL on 443 instead of HTTP and HTTPS, which I did, but without change, I still get the error. I also disabled load balancing across multiple Availability Zones with no success. I don't know if the EB config file makes problem, since I have only WSGIPath set and not the ASGI which is used by Daphine and Channels. There is no ASGIPath tag to try this. I found an article about new Application Load Balancer, but since it is a quite new service, I wasn't able to find anything for WebSockets with Django. Django Channels is also new, so not many questions and posts about it as well. -
django image upload rest framework and test client

How to make rotation of some resourse for threads?
I have the Community django model that contains ForeignKey field app that just contains access token for some rest api. class Community(models.Model): app = models.ForeignKey("VkApp") domen = models.CharField(max_length=300) @property def api(self): if self.app: access_token = self.app.access_token else: access_token = "" return PublicApiCommands(access_token=access_token, domen=self.domen) def get_posts(self, count): return self.api.get_post_list(count) class VkApp(models.Model): access_token = models.CharField(max_length=300) The method get_posts makes call to api property and returns the instanse of PublicApiCommands class.

It contains methods that makes some sort of requests.get('api.vk.com/bla?bla=bla') Now I want to switch app field to ManyToManyField from ForeignKey so that it will contain some set of access tokens. So I will have the ability to controll one commynity by more than 1 access token. And different communities will have either the same set of access tokens or completely different. I want to call get_posts method for different communities asynchronously (by making celery tasks for each community). But the rest api server limits count of calls to its api per second. So I need to forbid using of the same access token in two different threads. I have to choose free access token from the community.app_set.all(). I suppose that I need … -
Chaining filters
Django 1.10.1 On a page I have prepared a lot of controls. Some of them are organized as dynamically changing formsets. So, I don't even know how many of them are present. I need a chained filters with AND, OR and NOT logical operations. For example, I need something like this: Entry.objects.filter(headline__startswith='What').exclude(pub_date__gte=datetime.date.today()).filter(pub_date__gte=datetime(2005, 1, 30)).filter(Q(pub_date=date(2005, 5, 2)) | Q(pub_date=date(2005, 5, 6)) Once more the number of filters is changing. I was planning to ac like that: loop through request.POST and depending on a dozen of conditions prepare a string. The same string: "Entry.objects.filter(headline__startswith='What').exclude(pub_date__gte=datetime.date.today()).filter(pub_date__gte=datetime(2005, 1, 30)).filter(Q(pub_date=date(2005, 5, 2)) | Q(pub_date=date(2005, 5, 6))" So, the string is correct. But I can't make it work with exec(). I asked here: why it is not working. And the answer was: it will not work, run the Python code directly. I can construct something like that: entries = Entry.objects.filter( **kwargs ) But this is just one filter. I can't imagine how to chain such filters. Could you help me here&
