Problems with creating slug
Hello good afternoon I am developing an application that handles two roles of administrator and developer, the administrator data as developer is created without problems but when trying to use slug the program does not recognize them. This is my model class ProfileAdministrator(models.Model): user = models.OneToOneField(Administrator, on_delete=models.CASCADE) image = models.ImageField(default='avatar.png', upload_to='profiles/') slug = models.SlugField(max_length=50, unique=True) created_at = models.DateTimeField(auto_now_add=True) def __str__(self): return self.slug class ProfileDeveloper(models.Model): user = models.OneToOneField(Developer, on_delete=models.CASCADE) image = models.ImageField(default='avatar.png', upload_to='profiles/') slug = models.SlugField(max_length=50, unique=True) created_at = models.DateTimeField(auto_now_add=True) def __str__(self): return self.slug @receiver(post_save, sender=Administrator) def set_profile_administrator(sender, instance, *args, **kwargs): if kwargs.get('created', False): ProfileAdministrator.objects.create(user=instance) @receiver(post_save, sender=Developer) def set_profile_developer(sender, instance, *args, **kwargs): if kwargs.get('created', False): ProfileDeveloper.objects.create(user=instance) @receiver(pre_save, sender=ProfileAdministrator) def set_slug_profile_administrator(sender, instance, *args, **kwargs): if instance.user: instance.slug = slugify(instance.user) @receiver(pre_save, sender=ProfileDeveloper) def set_slug_profile_administrator(sender, instance, *args, **kwargs): if instance.user: instance.slug = slugify(instance.user) the program works fine even when I enter the slug, it does not recognize them, but the data is created correctly -

Django Social-Auth - save Stripe Email
I'm using Django Social Auth for Stripe. My goal is to create an account on my website with all those : email, stripe_account That works well except for the email: I got username = stripe_account without any email. I've read the Stripe Doc but I did not find anything on this. settings.py 'social_core.backends.stripe.StripeOAuth2', SOCIAL_AUTH_STRIPE_KEY = '****' SOCIAL_AUTH_STRIPE_SECRET = '****' SOCIAL_AUTH_STRIPE_SCOPE = ['read_only'] {% url 'social:begin' 'stripe' %} -
django custom authentication backend is not being called
I am using Django 3.1, and trying to figure out why my custom Authentication backend isn't being called. In my settings.py file I have: AUTHENTICATION_BACKENDS = ( 'sizzy.backends.EmailBackend', ) And in my sizzy.backends.py file I have: from django.core.exceptions import ObjectDoesNotExist from django.contrib.auth.backends import ModelBackend from .models import User class EmailBackend(ModelBackend): def authenticate(self, username=None, password=None): try: print("Trying the email backend!") user = User.objects.get(email=username) print("Got the user") if user.check_password(password): # check valid password return user print("password didn't work") except ObjectDoesNotExist: return None def get_user(self, user_id): try: print("Getting the user of the Email Bkacned") return User.objects.get(pk=user_id) except ObjectDoesNotExist: return None I then open up the manage.py shell and input: from django.contrib.auth import authenticate email = "billypop@a.pop" password = "password" user = authenticate(username=email, password=password) And it outputs: Login failed. Credentials: {'username': 'billypop@a.pop', 'password': '********************'} And I don't see any print statements. "Trying to get the Email Backend!" is never printed. Am I missing something? I tried changing my settings file to point to sizzy.backends.EmailBackendqwertyui just as a sanity check, and that threw an error instead of Login failed. So the backend is being loaded somehow I think, but never called. I've also tried changing out ModelBackend for BaseBackend, with the same results. -
MultiValueDictKeyError in accessing same form element in Django
I have some dropdowns here in my Index.html file. I have accessed the values selected in name=player1 and name=player2 dropdowns. But when I am going to access the value of name=selectcountry1 on same page in same form. Django is showing MultiValueDictKeyError. If I comment out the line in which I am accessing name=selectcountry1, all works fine. It takes the values of other dropdowns correctly. Also when I use request.POST.get('selectcountry1'), it is returning 'None', What is the problem as well as the solution. I don't want None, I want the value selected in dropdown.

Streaming multiple files through Django
I would like to stream a multiple files through Django. My ideas is to zip the files in memory then send it, as in the below code. But the problem is this will take too much time and ressources on my server. My question is: is there a better way to serve multiple urls through Django without zipping them ? import requests from django.http import StreamingHttpResponse def download(request): url = ['https://myondownlaod.com/file1.mp4','https://myondownlaod.com/file2.mp4','https://myondownlaod.com/file3.mp4'] in_memory = StringIO() for u in url: filename = os.path.basename(u) r = requests.get(u) zip = ZipFile(in_memory, "a") zip.write(r) zip.close() response = HttpResponse(mimetype="application/zip") response["Content-Disposition"] = "attachment; filename=my_zippedfiles.zip" in_memory.seek(0) response.write(in_memory.read()) return response I have seen this example which work pretty well when I tried it, but them my question would be how do you deal with multiple files. import requests from django.http import StreamingHttpResponse from django.contrib.auth.views import login_required def download(request): url = 'file_url_here' filename = os.path.basename(url) r = requests.get(url, stream=True) response = StreamingHttpResponse(streaming_content=r) response['Content-Disposition'] = f'attachement; filename="{filename}"' return response -

Django TemplateDoesNotExist, when trying to redirect user's
I have this structure,and basically what I want is to send the user to the right place depending on their group. myproject/ |-- myproject |--urls.py |--settings.py |--views.py |-- pluviais/ |--urls.py |--views.py |-- eletricistas/ |--urls.py |--views.py So when they login, my settings.py redirect to index, (LOGIN_REDIRECT_URL = 'index') myproject/urls.py from .views import index urlpatterns = [ path('', views.index, name='index'), path('admin/', admin.site.urls), path('login/', auth_views.LoginView.as_view(template_name='login.html'), name='login'), path('logout/', auth_views.LogoutView.as_view(), name='logout'), path('pluviais/', include('pluviais.urls')), path('eletricistas/', include('eletricistas.urls')), ] document_root=settings.MEDIA_ROOT) myproject/views.py from django.contrib.auth.models import Group,User from django.shortcuts import render, redirect def index(request): users_in_group = Group.objects.get(name="tablet").user_set.all() if request.user in users_in_group: user_responsaveis_pluviais = User.objects.filter(username=request.user, groups__name='Responsáveis - pluviais').exists() user_chefes_pluviais = User.objects.filter(username=request.user, groups__name='Chefes - pluviais').exists() print(user_responsaveis_pluviais) if user_responsaveis_pluviais == True or user_chefes_pluviais==True: return render(request, '/pluviais/tablet/') else: return render(request, '/eletricistas/tablet/') As you can see the idea is simply depending on the groups that the users are in, they are redirected to the right place ( or go to pluviais/ or eletricistas/ pluviais/urls.py urlpatterns = [ path('tablet', views.intervencao, name='intervencao'), ] eletricistas/urls.py urlpatterns = [ path('tablet', views.tarefas, name='tarefas'), ] the problem is that always giving me the error TemplateDoesNotExist at /, so maybe i am doing this wrong. -

django Admin - Filter foreign key selected depending on other choice in edit form (ithout jQuery)
I am working on a project which is administered by a super admin who puts in data for different companies. Lets say, I have these models: class Company(models.Model): name = models.CharField(max_length=100) class ContactPerson(models.Model): name = models.CharField(max_length=100) company = models.ForeignKey(Company) class Item(models.Model): company = models.ForeignKey(Company) contact_person = models.ForeignKey(ContactPerson) I need to ensure that I (in django admin) in the edit mode I only see contact persons which belong to the selected company. Being not in the year 2005 anymore I want to avoid writing loads of super ugly jQuery code. I guess I could overwrite the admin form for Item. But still I had to make the contact_person optional, so when I create a new Item, the list of contact persons need to be empty. Then I'd select a company, save it and go back to edit. Now the contact_person list would be filled and I could add somebody. But if I now change the comany, I'd have to remove all selected contact persons. Sure, I could to this in the form... but it looks SO hacky and not like a nice django solution. Anybody got some fancy ideas? Thanks in advance! Ronny -
how can I use foreign key to import users login from google by Django-allauth

Error in django when I add two new fields to a class model

Django query to get sum of previous values
