How to inherit from one class in Models.py into another class and turn it into a dropdown in Django
I have different classes in models.py that define an item's details. I need to make a new class that uses details listed in the existing classes and turn that into drop down menu (choices). How would I inherit from those other classes and turn it into a drop down? I am fairly new to python and django, I was thrown into the deep end and I'm trying to figure things out as I go, I'm not even sure where to start with this issue. Here is one of the classes: class StockItem(models.Model): item_id = models.AutoField(primary_key=True) stock_code = models.CharField(max_length=255) description = models.CharField(max_length=255) def __str__(self) return self.description Here is the class that needs to inherit from the above class: class StockInventory(models.Model): serial_number = models.CharField(max_length=255) stock_item = # needs to get the description from StockItem class above # and have its contents as a drop down stock_item in StockInventory needs to get what the user typed into description under StockItem and have it shown as a drop down with all descriptions previously entered. As I said, I am fairly new to this (been doing it for a month with no prior coding experience), so I apologize if I am asking something very stupid. -
Django Cookie-Cutter with Docker "python: can't open file 'manage.py': [Errno 2] No such file or directory" Error Macbook
I am trying to setup Django Project using Cookie-cutter with Docker using this tutorial: https://realpython.com/development-and-deployment-of-cookiecutter-django-via-docker/. I followed the instructions step by step, and I was able to successfully run all commands until the step when I need to run: docker-compose -f local.yml run django python manage.py makemigrations. This command gives me an error: python: can't open file 'manage.py': [Errno 2] No such file or directory . I've searched around online for the problem, the problem seems to be that the source files of the Django project is not copied inside the app directory of the docker. I tried running these commands to check if the files were there: docker-compose -f local.yml run django sh ls -la And indeed, the files weren't there, specially manage.py. Why is that so? Here's a screenshot: -
Django get all rows of models identified by foreign key
The European privacy policy requires to give information which data a website has about a user. With Django 1.11. I can get all relations to a specific user by ._meta.get_fields.

This is what my relations look like: In [1]: from test_project.people.models import Profile ...: user = Profile.objects.get(id=1000) ...: user._meta.get_fields(include_hidden=True) ...: Out[1]: (<ManyToOneRel: admin.logentry>, <ManyToOneRel: avatar.avatar>, <ManyToOneRel: dialogos.comment>, <ManyToOneRel: agon_ratings.rating>, <ManyToOneRel: announcements.announcement>, <ManyToOneRel: announcements.dismissal>, <ManyToOneRel: actstream.follow>, <ManyToManyRel: user_messages.thread>, <ManyToManyRel: user_messages.thread>, <ManyToOneRel: user_messages.groupmemberthread>, <ManyToOneRel: user_messages.userthread>, <ManyToOneRel: user_messages.message>, <OneToOneRel: tastypie.apikey>, <ManyToOneRel: guardian.userobjectpermission>, <ManyToOneRel: oauth2_provider.application>, <ManyToOneRel: oauth2_provider.grant>, <ManyToOneRel: oauth2_provider.accesstoken>, <ManyToOneRel: oauth2_provider.refreshtoken>, <ManyToOneRel: oauth2_provider.idtoken>, <ManyToOneRel: invitations.invitation>, <ManyToOneRel: account.emailaddress>, <ManyToOneRel: socialaccount.socialaccount>, <ManyToOneRel: base.contactrole>, <ManyToOneRel: base.resourcebase>, <ManyToManyRel: base.resourcebase>, <ManyToOneRel: layers.uploadsession>, <ManyToOneRel: maps.mapsnapshot>, <ManyToOneRel: people.profile_groups>, <ManyToOneRel: people.profile_user_permissions>, <ManyToOneRel: groups.groupmember>, <ManyToManyRel: services.service>, <ManyToOneRel: services.serviceprofilerole>, <ManyToOneRel: upload.upload>, <ManyToOneRel: favorite.favorite>, <ManyToOneRel: monitoring.notificationreceiver>, <ManyToOneRel: mapster_adapter.mapstoreresource>, <ManyToOneRel: pinax_notifications.noticesetting>, <django.db.models.fields.AutoField: id>, <django.db.models.fields.CharField: password>, <django.db.models.fields.DateTimeField: last_login>, <django.db.models.fields.BooleanField: is_superuser>, <django.db.models.fields.CharField: username>, <django.db.models.fields.CharField: first_name>, <django.db.models.fields.CharField: last_name>, <django.db.models.fields.EmailField: email>, <django.db.models.fields.BooleanField: is_staff>, <django.db.models.fields.BooleanField: is_active>, <django.db.models.fields.DateTimeField: date_joined>, <django.db.models.fields.CharField: organization>, <django.db.models.fields.TextField: profile>, <django.db.models.fields.CharField: position>, <django.db.models.fields.CharField: voice>, <django.db.models.fields.CharField: fax>, <django.db.models.fields.CharField: delivery>, <django.db.models.fields.CharField: city>, <django.db.models.fields.CharField: area>, <django.db.models.fields.CharField: zipcode>, <django.db.models.fields.CharField: country>, <django.db.models.fields.CharField: language>, <django.db.models.fields.CharField: timezone>, <django.db.models.fields.related.ManyToManyField: groups>, <django.db.models.fields.related.ManyToManyField: user_permissions>, <taggit.managers.TaggableManager: keywords>, <django.contrib.contenttypes.fields.GenericRelation: tagged_items>, <django.contrib.contenttypes.fields.GenericRelation: actor_actions>, <django.contrib.contenttypes.fields.GenericRelation: target_actions>, … -
Can I include complete Python scripts from GitHub to a Django application?
I have a question before I get started in a whole project... I'm in a team of 6 people, and I'm the only one using Python. I only use scripts already written, I just put in the arguments and that's it (scripts like Sherlock : https://github.com/sherlock-project/sherlock or Twint : https://github.com/twintproject/twint By the time, I learned a bit about coding in Python but really, it remains basic stuff. Now, my colleagues would like to use these applications too, and I thought about using Django, set up a web server, importing those scripts in the server, and giving the possibility to my colleagues to enter the args in a user-friendly way (some really don't know a thing about programmation) Is that possible with Django? If yes, will it be complicated? (I never used Django before and will follow courses, don't have a deadline) If no, do you guys know of any alternatives that I could use? Thanks for your answers! -
How to make a view that records the data from a ModelMultipleChoiceField form in database with django?

Django: Move calculations query set, away from Python code
In the following code snippet, my goal is to get outstanding_event_total_gross. To get that I first lookup for each ticket that belongs to the event the amount of sold_tickets. Out of that, I can calculate tickets_left. For each ticket I then calculate the outstanding_ticket_total_gross which I add up to outstanding_event_total_gross. A lot of the business logic happens in Python, but I wonder now if there is a more efficient query set to achieve what I am doing while calling the data from the database? tickets = Ticket.objects.filter(event=3) outstanding_event_total_gross = 0 for ticket in tickets: sold_tickets = ticket.attendees.filter( canceled=False, order__status__in=( OrderStatus.PAID, OrderStatus.PENDING, OrderStatus.PARTIALLY_REFUNDED, OrderStatus.FREE, ), ).count() tickets_left = ticket.quantity - sold_tickets outstanding_ticket_total_gross = tickets_left * ticket.price_gross outstanding_event_total_gross += outstanding_ticket_total_gross print(outstanding_event_total_gross) -
Django Channels equivalent to reverse()
In regular Django, I know I can use reverse to reverse a url. Is there equivalent functionality in django-channels for reversing a websocket url. If I have the following routing application = ProtocolTypeRouter({ "websocket": URLRouter([ url(r"^foo-websocket/$", FooConsumer, name="foo-example") ]), }) Is there something I can call like >>> reverse("foo-example") "/foo-websocket/" Or is this not possible in django-channels? -
How to properly unit test a Django middleware
I have to write unit tests for several Django Middlewares (Django > 1.10 styled middlewares). Project is an API, done with Django==2.2.3 and djangorestframework==3.9.4, I'm using standard Django unit testing module, and APIRequestFactory() and APIClient() test functions from Django REST framework to create mock requests for my tests. Here is an example of one middleware I want to test: from . import models class BrowserId(): def __init__(self, get_response): self.get_response = get_response def __call__(self, request): if hasattr(request, 'COOKIES') and 'mydomain.bid' in request.COOKIES: bid = request.COOKIES.get('mydomain.bid', None) else: bid = None request.bid = models.BrowserId(bid) if bid else models.BrowserId.random() response = self.get_response(request) response.set_cookie( conf.BID_COOKIE_KEY, value=request.bid, max_age=conf.COOKIE_MAX_AGE, domain=conf.BID_COOKIE_DOMAIN ) return response I want to test: * That browser ID has successfully been added to the request * That cookie has successfully been set on the response ...independently of others middlewares. So, to be more precise, part of the tests would vaguely have to look like this: from rest_framework.test import APIRequestFactory, APIClient, APITestCase from my_api.auth import middlewares, models class MiddlewaresTestCase(APITestCase): def test_fresh_browser_id_request(self): ??? SOME CODE TO PROCESS THE REQUEST BY THE MIDDLEWARE assert hasattr(request, 'bid') assert len(request.bid) == 30 def test_existing_browser_id_request(self): req = APIRequestFactory().get('/') mock_bid: str = 'abcd1234' req.COOKIES = {cookie_key: mock_bid} ???

Use the "Add More" functionality to a page(template) without submitting the existing form (and values) and submitting in the end
I have a ModelForm which asks for his dreams from the users. But I want users to provide with the "Add More" button so that they can submit the form (form fields) all at once without being the headache of reloading the page everytime the user presses ADD More For example, If a user is done with telling its one wish, he/she can n number of more wishes and once he/she presses Submit , the form should then submit the answer to the DB. How can I make a model for this? Will a single class Wish(model.Model): user=models.Foreignkey(User, on_delete=models.CASCADE) wishes= models.Charfield(max_length=1024) and a form from this model to render the form???? A user can have any number of wishes available in the DB so that he/she can delete at any point of time by checking/unchecking. -

Couple questions: how to bring data from the AddData into SiteData Also when user select the dropdown code from the SiteData, How to associate or populate data only for that SiteData how to map the data code with site_ip, site_prefix, site_data1,site_data2 Also noticed, when selecting dropdown, I get the value as number not the text name.. for example: site 68 site_ip 1 MODEL class Code (models.Model): name = models.CharField(max_length=4, default=None, blank=True, unique=True, error_messages={'unique':"Already in Used"}) def __str__(self): return self.name class AddData (models.Model): code = models.ForeignKey(Code, on_delete=models.CASCADE, null=True) data1_ip = models.GenericIPAddressField(protocol='IPv4', unique=True, error_messages={'unique':"Already in Used"}) data2_prefix = models.CharField(max_length=2, default='22') def __str__(self): return self.data1_ip class SiteData (models.Model): site = models.ForeignKey(Code, on_delete=models.CASCADE, null=True) site_ip = models.ForeignKey(AddData, on_delete=models.CASCADE, null=True) site_prefix = models.ForeignKey(AddData, on_delete=models.CASCADE, null=True) site_data1 = models.CharField(max_length=3, default='120') site_data2 = models.CharField(max_length=1, default='1') FORM class CODE_Form(forms.ModelForm): class Meta: model = Code fields = ('name',) class AddData_Form(forms.ModelForm): class Meta: model = MIDTIER_Add_Site fields = ('code', 'data1_ip', 'data2_prefix',) class SiteData_Form(forms.ModelForm): def __init__(self, *args, **kwargs): super(SiteData_Form, self).__init__(*args, **kwargs) if 'site' in self.data: c = self.data.get('site') c_ip = self.data.get('site_ip') self.fields['site'] = forms.ModelChoiceField(queryset=CODE.objects.filter(name=c)) self.fields['site_ip'] = forms.ModelChoiceField(queryset=CODE.objects.filter(name=c_ip)) class Meta: model = … -
Permission Denied when attempting to start Daphne systemctl process
I'm deploying a website using Django and Django-Channels, with Channel's daphne ASGI server substituting for the typical Gunicorn WSGI setup. Using this Gunicorn WSGI tutorial as a jumping off guide, I attempted to write a systemctl service for my daphne server, when I hit the below error: CRITICAL Listen failure: [Errno 13] Permission denied: '27646' -> b'/run/daphne.sock.lock' I was unfortunately unable to find any answers to why permissions would be denied to the .sock file, (in context to Daphne) so I was hoping I could get some hints on where to begin debugging this problem. Below are my daphne.socket and my daphne.service files. daphne.service [Unit] Description=daphne daemon Requires=daphne.socket After=network.target [Service] User=brianl Group=www-data WorkingDirectory=/home/brianl/autoXMD ExecStart=/home/brianl/autoXMD/env/bin/daphne -u /run/daphne.sock -b 0.0.0.0 -p 8000 autoXMD.asgi:application [Install] WantedBy=multi-user.target daphne.socket [Unit] Description=daphne socket [Socket] ListenStream=/run/daphne.sock [Install] WantedBy=sockets.target Based off the linked DigitalOcean tutorial, I start my service with sudo systemctl start daphne.socket. My guess is that there's some kind of discrepancy between setting up systemctl services for Gunicorn and Daphne that I missed, but I don't know for sure. (If it helps, I'm planning on using Nginx as the main server, but I haven't reached that point yet)
