Setting username in steam OpenID authentication with Django Allauth
I'm trying to configure a new django application to use Steam's OpenID authentication. The issue i'm running into is that when a new user sign's in (no form to allow them to customize username/specify email address) the something (either allauth or django.contrib.auth) defaults their User object's username to user. That field is unique... so a 2nd user can't login. I can't figure out what/where the new user object is created so we can customize that field. We want it to pull from extra_data['personaname']) ideally. -

Elastic Beanstalk with development and production environment?
I made a Django project and have successfully deployed it to an Elastic Beanstalk environment, let's say it's called app_name. However, I realized I needed 2 environments: development and production. The purpose of this is so I can try things out in development, and when I know it's fully working, I can deploy it in production for the public to use. I tried looking around their documentations and found Managing multiple Elastic Beanstalk environments as a group with the EB CLI . It basically says you can create a group of environments in one project with the command: ~/workspace/project-name$ eb create --modules component-a component-b --env-group-suffix group-name However, I'm not sure what a group means. I mean, I just need a development and production environment. I'm fairly new at this. How do I create and manage development and production environments for this purpose? I would ever be so grateful if someone were to shed some light to my problem. -

Django not sending Server Error (500) emails
I have a Django website hosted on a remote server. Whenever I encounter a 'Server Error (500)' I am supposed to get an email with more information about the error.

Django signal reciever not called after connecting to pre_delete signal
Goal I'm trying to implement a voting system that tracks when a user makes a vote on a specific object in the database. I'm tracking this using an intermediate UserVotemodel with a foreign key to the object that actually contains all the votes. Whenever the UserVote gets deleted I want to remove the vote on the related object. What I've tried Since bulk deletes do not call the model.delete() method, I want to accomplish the above by listening to the pre_delete signal. When I test the below receiver function using the Django test runner, everything behaves as expected from myapp.models.users import UserVote from django.db.models.signals import pre_delete from django.dispatch import receiver @receiver(pre_delete) def user_vote_handler(sender, instance, **kwargs): if sender in UserVote.__subclasses__(): # remove the vote from the related model Problem When I call delete() on a model instance in views.py, the function is not called. If I add print statements to the receiver function as below, none of the statements are printed. from myapp.models.users import UserVote from django.db.models.signals import pre_delete from django.dispatch import receiver @receiver(pre_delete) def user_vote_handler(sender, instance, **kwargs): print('function called') if sender in UserVote.__subclasses__(): print('condition met') # remove the vote from the related model I've read through the Signal Documention and … -
How to apply CSS class to dropdown in Django forms?
I have a form that has two fields who are dropdowns that show objects from other models through a Foreign Key. class NewFlight(ModelForm): class Meta: model = Flight fields = ('date', 'flight_id', 'company', 'airport') def __init__(self, *args, **kwargs): super(NewFlight, self).__init__(*args, **kwargs) self.fields['date'].widget = forms.DateTimeInput(attrs={'class': 'form-control', 'data-target': '#datetimepicker1'}) self.fields['flight_id'].widget = TextInput(attrs={'class': 'form-control'}) Both company and airport are objects from another model. So, if in the def __init__ I use the forms.Select widget, with the class form-control, I'll get the styling correct, but all the dropdown is empty. If I just leave the default form, all the "companies" are correctly displayed. -
Django: redirect to same page after custom login
I have this code for a custom login: def login(request): if request.user.is_authenticated: return render(request, 'listings/index.html', {}) if request.method == 'POST': username = request.POST.get('username') password = request.POST.get('password') user = authenticate(request, username=username, password=password) if user is not None: if not request.POST.get('remember_me', None): request.session.set_expiry(0) auth_login(request, user) return redirect('dashboard') else: messages.error(request, "Les informations que vous venez d'entrer sont incorrects. Veuillez réessayer.") return render(request, 'dashboard/login.html', {}) return render(request, 'dashboard/login.html', {'randomtip': random.choice(RandomTip.objects.all())}) And all my views have @login_required and @user_passes_test decorators. As you can see in the login function, when the user is authenticated and logged in, s/he gets redirected to dashboard. But I have a session expiry limit (where users have their sessions expired after 6 minutes). And when they are in a specific page, they get redirected to the login after the expiry of the cookie. The problem here is that if they are in a page other than dashboard, after they login they get redirected to the dashboard. I want them to stay in the same page after they login again. How can I know the path of the current page visited and put it here: return redirect(current_page)? -
How to bulk increment a unique IntegerField?
