Trouble implementing an already developed Django App
Hello fellow programmers, I'm having trouble and also have several questions about the implementation of this app in Django. https://github.com/voxy/django-audio-recorder It has a 'quick start' section that I have tried to follow several times but with no success. My questions are: -What is really happening when I run this line in terminal pip install git+https://github.com/voxy/django-audio-recorder.git#egg=django-audio-recorder -When the developer refers to 'create your models, views and forms' should i already have a project setup django-admin startproject X and change lines of code in that folder specifically? -I also used the git clone https://github.com/voxy/django-audio-recorder.git to get the folders and see what is really going on in this app, unfortunately I can't get it to work. Would apreciate some insight on this matter, thank you in advance. -

stefanfoulis/django-phonenumber-field display format of phone number in template
I'm trying to figure out how to display a phone number using stefanfoulis/django-phonenumber-field. I have stefanfoulis/django-phonenumber-field[phonenumberslite] installed. In my settings file I have: PHONENUMBER_DB_FORMAT = "NATIONAL" PHONENUMBER_DEFAULT_REGION = "US" In my model I have: phone_number = PhoneNumberField(blank=True) In my form I have: phone_number = PhoneNumberField(max_length=25,required=False) And in my template I have: {{ myform.phone_number }} I am able to enter a phone number in a variety of formats (831-555-5555, 831-555-5555, 831.555.5555) and it stores properly in the database as +18315555555. But when I use the form field in a template it always displays as +18315555555. I would like it to display as either 831-555-5555 or (831) 555-5555. How do I make the phone number display in one of these formats in my template? Is there a tag modifier? -
Django ORM - update ForeignKey field with model's ManyToManyField
I have a model: class User(AbstractUser): name = models.CharField(max_length=255) organizations = models.ManyToManyField(Organization) active_organization = models.ForeignKey(Organization) Now I want to update active_organization with one of the organizations within the model, so I want to do something like this: User.objects.filter(active_organization=q).update(active_organization=F('organizations__pk')[0]) sadly F is not subscriptable, I've also tried, User.objects.filter(active_organization=q)\ .update(active_organization=Subquery( Organization.objects.filter(pk=OuterRef('organizations').objects.first().pk))) But in this case it tells me the OuterRef should be inside a SubQuery which it is, so I'm completely at a loss here how this should be approached. -

Django simple_history "missing 1 required positional argument: 'on_delete'"
I've tried to install simple_history to my existing Django app- but have encountered a few errors including the below. I've encountered these errors when attempting to run "makemigrations". I could fix this by adding the on_delete to the package models file- though because of the other issues I encountered before this one, it seems like there might be a deeper issue. My django version is: (2, 2, 7, 'final', 0) Python version is 3.7.3 'history_user': CurrentUserField(related_name=rel_nm), File "appname/lib/python3.7/site-packages/simple_history/models.py", line 26, in __init__ super(CurrentUserField, self).__init__(User, null=True, **kwargs) TypeError: __init__() missing 1 required positional argument: 'on_delete' Thanks! -

Average for ratings in Django
I working on an app using django and python at school. It an app for writing reviews and rating movies. I would like to implement a rating system, so I can display the average rating for a film based on the rating given in the reviews. At the moment this code gives the rating in descending order for all reviews, and not the average. Like if I got two reviews for a movie, with score 1 and 5, I get both, but not one that says 3. Please help!

Celery after_task_publish signal fire but other signals do not?

Every task failing to execute on Google Cloud Tasks
I need to run some asynchronous tasks in a Django app, and I started to look into Google Cloud Tasks. I think I have followed all the instructions - and every possible variation I could think of, without success so far. The problem is that all created tasks go to the queue, but fail to execute. The console and the logs report only a http code 301 (permanent redirection). For the sake of simplicity, I deployed the same code to two services of an App Engine (standard), and routed the tasks request to only one of them. It looks like the code itself is working fine. When I go to "https://[proj].appspot.com/api/v1/tasks", the routine executes nicely and there's no redirection according to DevTools/Network. When Cloud Tasks try to call "/api/v1/tasks", it fails every time. If anyone could take a look at the code below and point out what may be causing this failure, I'd appreciate very much. Thank you. #-------------------------------- # [proj]/.../urls.py #-------------------------------- from [proj].api import tasks urlpatterns += [ # tasks api path('api/v1/tasks', tasks, name='tasks'), ] #-------------------------------- # [proj]/api.py: #-------------------------------- from django.views.decorators.csrf import csrf_exempt @csrf_exempt def tasks(request): print('Start api') payload = request.body.decode("utf-8") print (payload) print('End api') return HttpResponse('OK') #-------------------------------- # … -
Django how to create multiple model objects at once - sharing all values but one
I have been making an app for tracking user wages and issues that they are working on. I would like to have a view from which I could specify payment details and select mutliple Users to whom the payment will be made. I have a User model and Payment model. In the Payment model there is a FK to Users. Is there a way to have a view where I'll select multiple Users, fill the other shared vlaues (such as date, value etc.) in the form and then hit submit. I'm looking for a way to override class based functions so that it iterates through the multiple select field (bunch of User ids) and then creates and saves Payment model object with the FK and shared fields. Thank you very much. -
