Allauth get_user_model() CustomUser issue
I am currently trying to get the user model in a function-based view but keep getting the following error. I have allauth installed and created a customer user using the allauth.account model. I attached my model and the migration. I have looked in my database and have users in, however every time I call the user in the view it gives me a customer user error.

Reuse same image Django
I have a django model that has an image field. I want to change the field so it can upload a new image or reuse the same image that was already been uploaded. But I want the field so it can have an option to reuse the same image only on admin. If it is on form, it only can upload an image. How can I do that? The main thing is that the admin can have an option to upload a new image or reuse the same image that was already been uploaded. But the regular user can only upload a new image and doesn't have an option to reuse an image. Is there any way to solve this problem? -

HTML for loop won't pickup the variable I ask for
I have a for loop in my HTML template, I want it to display certain information for the author of the posts but it won't display anything: {% for post.author in post %} <img class="rounded-circle profile-img" src="{{ post.author.profile.image.url }}"/> <div class="media-body"> <h2 class="account-heading">{{ view.kwargs.username }}</h2> <!-- only This works --> <p class="text-secondary">{{ post.author.first_name }} {{ post.author.last_name }}</p> <p class="text-secondary">{{ post.author.email }}</p> <div class="container"> <p class="lead"><Strong>Sobre mi:</strong></p> <p class="lead">{{ post.author.description }}</p> </div> <br> <p class="text-secondary">Se unió el {{ post.author.date_joined }}</p> <p class="text-secondary">Última vez visto: {{ post.author.last_login }}</p> <p class="mb-0">{{ post.author.about }}</p> </div> {% endfor %} Before I made those changes to the for loop it was working, but not exaclty like I wanted it to. The loop is made to display certain user's information, so I can't have it display the same info more than 1 time, that's why I'm not satisfied with the for loop here: {% for post in posts %} <img class="rounded-circle profile-img" src="{{ post.author.profile.image.url }}"/> <div class="media-body"> <h2 class="account-heading">{{ view.kwargs.username }}</h2> <!-- only This works --> <p class="text-secondary">{{ post.author.first_name }} {{ post.author.last_name }}</p> <p class="text-secondary">{{ post.author.email }}</p> <div class="container"> <p class="lead"><Strong>Sobre mi:</strong></p> <p class="lead">{{ post.author.description }}</p> </div> <br> <p class="text-secondary">Se unió el {{ post.author.date_joined }}</p> <p class="text-secondary">Última … -
geodjango creating GEOS multi geometries fails after python upgrade (M!)
I have an @property on a model that gets a bounding box for all the geometries associated with a dataset. This code has worked fine for a couple of years. Now, on a new M1 mac laptop, I upgraded Python (3.7.4 to 3.9.7) and the configuration of GDAL and GEOS was difficult. But as I understand, django.contrib.gis includes its own versions of those libraries. Relevent code snippets: from django.contrib.gis.geos import GeometryCollection, MultiPoint, Point from places.models import PlaceGeom from datasets.models import Dataset class Dataset(models.Model): fields … @property def bounds(self): dsgeoms=PlaceGeom.objects.values_list(‘geom’,flat=True).filter(place__dataset=self.label) print(tuple(dsgeoms[:2])) # (<Point object at 0x12ee39988>, <Point object at 0x12ee39a08>) gc = GeometryCollection(tuple(dsgeoms[:2])) return json.loads(gc.envelope.geojson) if pg_geoms.count() > 0 else None This crashes when creating the GeometryCollection with no real clue as to why, in PyCharm: “process finished with exit code 138 (interrupted by signal 10: SIGBUS)” in django shell: “67692 bus error ./manage.py shell” in browser: simply quits runserver So I simply tried the examples from the Geodjango docs at https://docs.djangoproject.com/en/2.2/ref/contrib/gis/geos/, and though the Point and LineString creation worked, GeometryCollection and MultiPoint did not, with the shell error "68483 segmentation fault ./manage.py shell" I'm stumped, but before I try building the bbox with Shapely and multiple transformations, thought I'd ask … -

Set is_staff to true for userthat login via django allauth google
I am using allauth in Django in order for users to login via their Google accounts. Everything works fine, user logs in, account is created and saved in the db, but the problem is I want the new users to automatically be staff members by setting is_staff to true. I was looking at the official docs on how to override data and I did this: in settings.py: ACCOUNT_FORMS = { 'signup': 'myapp.forms.MyCustomGoogleSignupForm' } and in myapp/forms.py (the directory that has the wsgi.py file. Is this the right location? I have not created a new app directory for loggin in with google.) class MyCustomGoogleSignupForm(SignupForm): def save(self, request): # Ensure you call the parent class's save. # .save() returns a User object. user = super(MyCustomGoogleSignupForm, self).save(request) # Add your own processing here. user.is_staff = True # You must return the original result. return user but this does not work. Anyone has any ideas? Thank you -
Data cannot saved in django formview
I'm going to receive data and save it using form and save it. But I can't get any result. Let me know what I'm doing wrong. I set up a model. And I wrote a form to get the input. Forms.Form was used.

Using unittest.mock to mock a DRF response
My example is pretty basic: # urls.py from django.urls import include, path from rest_framework.routers import DefaultRouter from core import views router = DefaultRouter() router.register(r'core', views.CoreViewSet) urlpatterns = [ path('', include(router.urls)), ] # views.py from rest_framework import mixins, viewsets from .models import Numbers from .serializers import NumbersSerializer class CoreViewSet(viewsets.GenericViewSet, mixins.ListModelMixin): queryset = Numbers.objects.all() serializer_class = NumbersSerializer # serializers.py from rest_framework import serializers from .models import Numbers class NumbersSerializer(serializers.ModelSerializer): class Meta: model = Numbers fields = '__all__' # models.py from django.db import models # Create your models here. class Numbers(models.Model): odd = models.IntegerField() even = models.IntegerField() class Meta: db_table = 'numbers' What I'm trying to do is mock the request to the /core/ URI so it returns a mocked response and not the response from the database. For example, considering unit testing in a CI pipeline when the database isn't available. The below is what I have, but print(response.data) returns the actual response and not the mocked one: import unittest from unittest.mock import patch from rest_framework.test import APIClient class CoreTestCase(unittest.TestCase): @patch('core.views') def test_response(self, mock_get): mock_get.return_value = [{'hello': 'world'}] client = APIClient() response = client.get('/core/') print(response.data) Not finding the documentation very intuitive in figuring this out, so asking how I should be implementing … -

Can't get Bootstrap navbar to work properly in Django project
I'm trying to get Bootstrap working on my Django project but can only manage getting the CSS to work but not the navbar functionalities. For example, the dropdown doesn't work and when making the window smaller, the 3-bar icon that substitutes as the navbar doesn't work either. The navbar is ripped straight from Bootstrap's documentation. I've been going at this for some time and have looked at solutions online but nothing seems to work for me. I have already tried swapping the JQuery script tag and the Bootstrap JS tag and moved my script tags to just before my </body> tag.

Should blockchain technology be handled on the client side or the server side?
I'm a full-stack developer (specifically Django web developer). Blockchain is new to me. I heard that blockchain applications can be written with both python (on the server side) and javascript (on the client side). So, what programming langue is to write Blockchain? Do I write it on the server side or the server side? My guess is handling it in the server would be more secure because hackers can read client code and inject malicious javascript code through the console panel. Am I right? To be concise, my question is Should blockchain technology be handled on the client side or the server side? -
Django only one default row
I have a ManyToMany relationship that indicates a Doctor can have many specialties, but only one of them is the PRIMARY one. I've designed a custom M2M class as follows: class Doctor(models.Model): account = models.ForeignKey(Account, on_delete=models.CASCADE) specialty = models.ManyToManyField(Specialty, through='DoctorSpecialty') ..... class Specialty(models.Model): title = models.CharField(max_length=45) ..... class DoctorSpecialty(models.Model): doctor = models.ForeignKey(Doctor, on_delete=models.CASCADE) specialty = models.ForeignKey(Specialty, on_delete=models.CASCADE) default = models.BooleanField(default=True) The doctor can have many specialties, but only one of them can be the default one. He or she can have many specialties with the default field set as False, but cannot have more than one with the default field set as True I wanted to do something like this: class Meta: constraints = [ models.UniqueConstraint(fields=['doctor', 'specialty', 'default'], name='unique specialty') ] But this will mean that the doctor can have only one specialty as a default one, and only one other as a non default one. How can we achieve this with the minimum of code? PS: I could leave it without constraints and try to validate adding new entries by checking if another default specialty exists, but this will add a lot of overhead and exception raising. -

Django model update with race condition protection
Let's say we have the database table workers with the following fields: id [int] active [bool] Let's assume we have N > 1 records in the database. These records are representing background processes. It's required to allow exactly one process to work. My question is: how to avoid race conditions when all background processes are trying to become an active process. In plain SQL, I would try around something like this: UPDATE workers SET active = (SELECT MAX(*) FROM workers) XOR 1 WHERE id=...; It seems that only one worker can be lucky enough to survive the XOR. My real question is: how to achieve the same effect using Django models. I'm looking around F expressions but haven't found inspiration yet. -
