How to get certain fields in database from different models to template in django?
I am trying to show cities in country in cities_lits pages, but haven´t been able to figure out how to do it. I ma able to show countries and go through the link to cities pages which shows all cities, but not able to show only cities which belong to one certain country. City model has a foreign key relationship with Country model. Is it better to add logic under views by example under CitiesListView where I filter out cities in one country and add these cities to template? Or try to add it on template by filtering through objects with template tags and for and if loops? What is the best approach and why? I tried to add to CitiesListView context class CitiesListView(ListView): template_name = "cities_list.html" model = City context_object_name = "cities" country = Country.objects.get(id=1) def get_context_data(self,**kwargs): context = super(CitiesListView,self).get_context_data(**kwargs) context['cities'] = City.objects.filter(country=country) return context but wasn´t able to render it to template got an error that name 'country' is not defined even though I added it to CitiesListView. Where I go wrong and what do I miss?

Next parameter in url not showing but is printing correctly in django
This is my signup view: def signup(request): next = request.GET.get('next', '') print(next) if request.user.is_authenticated: return redirect('/') else: if request.method == "POST": first_name=request.POST['first_name'] email=request.POST['email'] password=request.POST['password'] cpassword=request.POST['cpassword'] signup_uri = f'/signup?next={next}' if password==cpassword: if User.objects.filter(email=email).exists(): messages.info(request,'Email already in use') return redirect(signup_uri) elif User.objects.filter(mobile=mobile).exists(): messages.info(request,'Mobile Number already in use') return redirect(signup_uri) else: user=User.objects.create_user(first_name=first_name,email=email,password=password) user.save(); return redirect(f'/login?next={next}') else: messages.info(request,'Passwords not matching') return redirect('signup_uri') else: return render(request,'signup.html') The problem I am facing is that when I am printing next under def signup it is printing it correctly but when it has to redirect it redirects without showing anything as next in url. That is signup_uri = f'/signup?next={next}' and return redirect(f'/login?next={next}') are showing the {next} as empty.What could be the reason?Any help would be appriciated. -
Django circular import error - how to debug it?
I tried to follow this tutorial https://blog.nicolasmesa.co/posts/2018/10/saas-like-isolation-in-django-rest-framework/ using: Django 3.1 Python 3.6 Everything I did including 'The User Messages App' paragraph worked perfectly right before the 'Refactoring the views' passage and then I got the error when running manage.py runserver django.core.exceptions.ImproperlyConfigured: The included URLconf 'saas_django.urls' does not appear to have any pa tterns in it.

Difference between form class attribute "fields" and "declared_fields" in Django
I was looking into a way to change the fields of a form dynamically in Django and came across the fields attribute. This attribute makes sense to me and worked as expected.

How can i constrain or choose between one or other foreign key?
The problem is conceptual (databases relationships), so the language isn't the focus here, but I'm using Python and Django.

I know that i can simply create 2 Address classes, eg, CustomerAddress, CompanyAddress, each one with its correct foreign key: class Company(models.Model): name = models.CharField(max_lenght=100) #example class Customer(models.Model): name = models.CharField(max_lenght=100) #example class CompanyAdress(models.Model): country = models.CharField(max_lenght=100) #example state = models.CharField(max_lenght=100) #example company = models.ForeignKey(Company, on_delete=models.PROTECT) class CustomerAdress(models.Model): country = models.CharField(max_lenght=100) #example state = models.CharField(max_lenght=100) #example customer = models.ForeignKey(Company, on_delete=models.PROTECT) But i don't want to for two reasons: The duplicated code and the fact that in django admin panel I will have two separeted address lists, wich doesn't makes much sense, since all address are structurally indentical. I can fix the duplicated code creating a base class, inheriting from it and etc, but i … -
