How to add queryset to ManyToMany relationship?
I have following models: class EnMovielist(models.Model): content_ID = models.CharField(max_length=30) release_date = models.CharField(max_length=30) running_time = models.CharField(max_length=10) actress = models.CharField(max_length=300) series = models.CharField(max_length=30) studio = models.CharField(max_length=30, null=True) director = models.CharField(max_length=30) def __str__(self): return self.content_ID class EnActress(models.Model): name = models.CharField(max_length=100, null=True) movielist = models.ManyToManyField(EnMovielist, related_name='movies') def __str__(self): return self.name I got error when I try to this in Django shell, b = EnActress.objects.values_list('name', flat=True) a = EnMovielist.objects.filter(actress__contains=b).values_list('content_ID') b.movielist.add(a) AttributeError: 'QuerySet' object has no attribute 'movielist' How can I django queryset add into many-to-many field? I have no idea why this is happening.. Any help appreciated! :) -
Multiple in memory instances of same model
Lets say I have a process that fixes the username and email of a User model. def fix_model(user_id): user = User.objects.get(user_id) fix_username(user) # lets say for arguments' sake that we can't pass the user to fix_email (call it legacy) fix_email(user_id) user.save() def fix_username(user): user.username = 'correct_username' def fix_email(user_id): user = User.objects.get(user_id) user.email = 'correct_email' user.save() # <-- necessary because it is a standalone task Of course what will happen is that the user will first be saved inside the fix email call and then the in memory object is saved with the correct username. When we check the database afterwards we don't have the correct email address anymore. Of course this is a contrived example. There are many easy ways to fix it here, e.g. moving the user.save() up one line or return the instance of user in fix_email etc. In my real use case i have no direct control over when the models will be saved or the signature of the methods. My question is the following: Is there a way in Django to have all instances that are retrieved from the database pass through a manager of sorts, that will return pointers to the same in memory objects … -
How to recursively query in django efficiently?
I have a model, which looks like: class StaffMember(models.Model): id = models.OneToOneField(to=User, unique=True, primary_key=True, related_name='staff_member') supervisor = models.ForeignKey(to='self', null=True, blank=True, related_name='team_members') My current hierarchy of team is designed in such a way that there is let's say an Admin (who is at the top most point of hierarchy). Now, let's say 3 people (A, B, C) report to Admin and each one of A, B and C have their own team reporting to them and so on. I want to find all the team members (boiling down to the bottom most level of hierarchy), for any employee. My current method to get all the team members of a person is like: def get_team(self): team = [self] for c in self.team_members.all(): team += list(c.get_team()) if len(team) > 2000: break return team But obviously, this leads to a lot of db calls and my API eventually times out. What could be more efficient way to fetch all the members of a team? -

Django : Make an ordered list of objects each having reference to previous
I am making a portal who serves for interview procedures for job interviews. I want to make a model for each interview round. First round will be started for every job.

Django project template loader setup
It is possible setup django project template loading priority so that first of all it loos to app "template" folder and after to project "tempalte". If template exist in app folder, then use it. If not exit in app folderm, then try load from project folder. Or it is not normal way to load templates? I ask because see in exception, where Django try load first of all global templates: Template-loader postmortem Django tried loading these templates, in this order: Using engine django: django.template.loaders.filesystem.Loader: D:\myprojects\my-website\src\templates\home.html (Source does not exist) django.template.loaders.app_directories.Loader: C:\User\Python27\lib\site-packages\django\contrib\admin\templates\home.html (Source does not exist) django.template.loaders.app_directories.Loader: C:\User\Python27\lib\site-packages\django\contrib\auth\templates\home.html (Source does not exist) django.template.loaders.app_directories.Loader: D:\myprojects\my-website\src\website\templates\home.html (Source does not exist) -

Managing Django handler's thread
Is it a webserver spawning/controlling a thread(process) which calls request handler? Or is there any asynchronous/multithreaded architecture in Django itself? The problem is that when an (ajax) request is being processed for a long time, and during this client re-sends it again, the previous handler gets terminated. I would like to have some control over this: e.g. perform some cleanup actions. Or terminate the handler manually in some cases. -

Django - how to break down monolitic project into apps?
I'm new to Django and I have been working on a Django project for some time now, It's an event registration and management tool for conferences, Event organisers can create an Event, and an event registration page for attendees to RSVP. Currently all the functionality of the project is stored in one monolithic Django app, I want to separate this app into smaller apps. I'm having a difficult time understanding when to separate a Django project into apps, are there any hard and fast rules for this. This is how I am considering breaking down the monolithic app. Account app - for event organisers to create an account and manage their profile. Event app - which consists of the event details, agenda, photos, sponsors and speakers of the event) Attendee app - which is an app that manages attendees, whether they have registered etc. Communication app - creating custom emails and email templates to send to attendees. RSVP page app - this is an editable registration page that contains basic information about the event, attendees will rsvp on this page by entering their data in a form. Is this a logical way of breaking down my project into apps. Should … -
How do I use Docker on BitBucket pipelines to test a Django app that needs PostGIS?
I'm trying to build automated testing on Django app on a private BitBucket repo, using BitBucket pipelines. I have all the tests in place, and they can be run using ./manage.py test or using tox. This works fine locally, where the tests build a (temporary) PostGIS test database. PostGIS and stuff like gdal is necessary for all the requirementst.txt to properly install. I'm having problems finding a Docker image that gives me a full Python + PostGIS/gdal etc stack on Docker, and I lack the skills to build it myself. My failed attemps are documented on GitHub: https://github.com/zostera/docker-django-ci Can someone point me in the right direction (tutorial) or perhaps help me out with a working example? -
Django Rest Framework Ordering Filter, order by nested list length
I'm using OrderingFilter globally through settings.py and it works great. Now I would like to order on the size of a nested list from a ManyToManyField. Is that possible with the default OrderingFilter? If not, is there a way I can do it with a custom filter, while keeping the query param ordering in the url (http://example.com/recipes/?ordering=). For the sake of consistency. Oh and the ManyToManyField is a through table one. These are my models.py: class Recipe(models.Model): name = models.CharField(max_length=255) cook_time = models.FloatField() ingredients = models.ManyToManyField(IngredientTag, through=Ingredient) My serializers.py: class IngredientTagSerializer(serializers.ModelSerializer): class Meta: model = IngredientTag fields = ('id', 'label') class IngredientSerializer(serializers.ModelSerializer): class Meta: model = Ingredient fields = ('amount', 'unit', 'ingredient_tag') depth = 1 class RecipeSerializer(serializers.ModelSerializer): ingredients = IngredientSerializer(source='ingredient_set', many=True) class Meta: model = Recipe fields = ('id', 'url', 'name', 'ingredients', 'cook_time') read_only_fields = ('owner',) depth = 2 And my views.py: class RecipeViewSet(viewsets.ModelViewSet): """ API endpoint that allows recipes to be viewed or edited.
