How to remove a permission from model?
So I had a permission in my model class like this: class Meta: permissions = (("can_send_messages", "Can send messages"),) This automatically created a migration that does this: operations = [ migrations.AlterModelOptions( name='organization', options={'permissions': (('can_send_messages', 'Can send messages'),)}, ), ] Now I removed class Meta and the permission from my model class. How do I make a migration that will undo that automatically created migration? -

QBO with Django Open Id, Callback Anonymous User
I have hooked up Django to QBO (QuickBooks Online) and seem to be having trouble with 1 random account. I am using the Intuit oauth Python library with Django. For this one particular account, the request gets sent off to QBO, login and connect. Upon going back to my application, this callback is invoked. The request appears to be in some odd state because the logs tell me that request.user is an AnonymousUser. Also before I commented it out, this would actually fail on the state_tok check. It almost seems like the session is randomly getting cleared on Chrome browser, or the request is getting lost. Log: File "/app/public/views.py", line 867, in acccounting_callback business_account = BusinessAccount.objects.get(user=request.user) ...

Django click streams and Django packages in general
I am really new to coding and Django. I had two questions. I want to know more about Django clickstreams and if it is possible to achieve it? I researched using google. However the max I found was this Django package called django-clickstreams..however I don't see any updates around this. I wanted to know if there is a way to achieve user actions on a site using django and If so, is there any direction you can point me to? This brings me to the question around Django packages. Can they be trusted once they are added to your project ? Or there are any risks? Thank you -

Django allauth redirect users that signup to email confirmation page by tracking their session
I have implemented an application which uses django-allauth. When users initially signup, it asks them for email verification on the page. Without authentication them (It doesn't authentication after they have signup. My intention is that based on the user session, the website will redirect users to an html page that they can change their email address (Something that Facebook does on signup and keeps track of you when you recently signup). My sign up view is: def signup(request): if request.method == 'POST': form = SignUpForm(request.POST) if form.is_valid(): user = form.save(commit=False) #raw_password = form.cleaned_data.get('password1') #user = authenticate(username=user.username, password=raw_password) user.is_active = False user.save() send_email_confirmation(request, user, True) return render(request, 'account/custom_snippets/verification_sent.html', {'email': user.email}) else: form = SignUpForm() return render(request, 'main/signup.html', {'form': form}) Now I would always like to redirect users to verification_sent.html if they recently signed up and the application is waiting on for user to verify their app. My email update view for newly signed users is: def update_user_email_on_verification(request): data = dict() user = request.user if request.method == "POST": new_email = request.POST.get('email') user.add_email_address(request, new_email) return render(request, 'account/custom_snippets/verification_sent.html', {'email': new_email}) else: context = { 'email':'' } data['form'] = render_to_string('account/email/update_email.html',context,request=request) return JsonResponse(data) my login view: @user_passes_test(lambda user: not user.username, login_url='/home/', redirect_field_name=None) def user_login(request): message = …
