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. If you see valid patterns in the file then the issue is probably caused by a circular import I tried different types of import but I can't figure out where the cirular import happens My steps to find a bug: the saas_django/urls.py refers to user_messages app: path('api/v1/user-messages/', include('user_messages.urls')), user_messages/urls.py: from django.urls import path from . import views urlpatterns = [ path('', views.UserMessageList.as_view(), name=views.UserMessageList.name), path('<uuid:pk>', views.UserMessageDetail.as_view(), name=views.UserMessageDetail.name), ] It seems like something is wrong with the imported user_messages/views.py from rest_framework import permissions from rest_framework import generics from . import serializers from .models import UserMessage class UserMessageList(generics.ListCreateAPIView): name = 'usermessage-list' permission_classes = ( permissions.IsAuthenticated, ) serializer_class = serializers.UserMessageSerializer queryset = UserMessage.objects.all() def perform_create(self, serializer): user = self.request.user company_id = user.company_id # Added from_user serializer.save(company_id=company_id, from_user=user) def get_queryset(self): # Changed this to use the UserMessageManager's method return UserMessage.objects.get_for_user(self.request.user) class UserMessageDetail(generics.RetrieveAPIView): name = 'usermessage-detail' permission_classes = ( permissions.IsAuthenticated, ) … -

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. However I also just came across the class attribute declared_fields and I cant wrap my head around what this does differently and why its there. I also cant find an explanation online for it. Can someone please explain the difference between the two? -

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 have 3 models/tables: Company Customer Address Eg. class Company(models.Model): name = models.CharField(max_lenght=100) #example class Customer(models.Model): name = models.CharField(max_lenght=100) #example class Adress(models.Model): country = models.CharField(max_lenght=100) #example state = models.CharField(max_lenght=100) #example # here i want the adress owner # i could put something like this: company = models.ForeignKey(Company, on_delete=models.PROTECT) customer = models.ForeignKey(Customer, on_delete=models.PROTECT) I want the address to belong to the customer or the company, but not both. 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 … -

run Gunicorn with WSGI inside a folder
I have my project structure as below. I use folders to put all the settings files in them. ~/myproject/ - env - server - api - home - settings - dev.py - prod.py - wsgi - dev.py - prod.py the myproject/server/home/wsgi/dev.py is: import os from django.core.wsgi import get_wsgi_application os.environ.setdefault("DJANGO_SETTINGS_MODULE", "home.settings.dev") application = get_wsgi_application() also inside myproject/server/home/settings/dev.py is: WSGI_APPLICATION = 'home.wsgi.dev.application' with all the above setup the server runs perfectly. When i try to deploy and run the gunicorn, it just fails.

Why django is accepting two diiferent passwords? Giving no error at all

debugging jQuery ajax - works on localhost server, doesn't work on production server
For example, the following ajax call is working just fine on my localhost: $.ajax({ type:"POST", url: "/teachers/studentMonthAgenda/", data:{ 'event_start': dayMs, 'event_end': endOfMonthMs, 'csrfmiddlewaretoken': $('input[name=csrfmiddlewaretoken]').val(), }, dataType: 'json', cache: false, success: function( eventData ) { getEvents(eventData); }, error: function(xhr, status, error){ var errorMessage = xhr.status + ': ' + xhr.statusText alert('Error - ' + errorMessage); } }); On my production server with the following attributes: Python 3.6 running on 64bit Amazon Linux/2.9.13 elastic beanstalk the same code leaves absolutely no trace of an error. I'm finding ajax to be the only thing that can't be debugged easily on elastic beanstalk because it leave absolutely squat in the log file if there is an error, and there clearly is something going wrong in this case. The inputs (dayMS and endOfMonthMs) are good too, so it really must be the ajax call that is the problem. I should add, it was working before I redirected traffic from port 80 to port 443. -
Django: Is there a way to use widgets on functions without class in view.py?
I am new to django and trying to use widgets and bootstrap to make my forms template look better. I saw a video tutorial on how to do so, but he uses class in views.py while I want it on function I created. Is there anyway to use the given widget on function addItem? The forms.py file: class ItemsForm(ModelForm): class Meta: model = Item fields = "__all__" widgets = { 'name': forms.TextInput(attrs={'class': 'form-control'}), 'price': forms.TextInput(attrs={'class': 'form-control'}), 'category': forms.Select(attrs={'class': 'form-control'}), 'image':forms.TextInput(attrs = {'class':'form-control-file'}), } My views.py file: def addItem(request): if request.method=="POST": form=ItemsForm(request.POST, request.FILES) print(form) if form.is_valid(): try: print("valid") form.save() return redirect("/items") except: print("validation failed") else: form=ItemsForm() print("invalid") return render(request, "dashboard/items/items_form.html",{'form':form}) The template I am trying to render it in: <div class="form-group"> <form action="" method="POST" enctype="multipart/form-data"> {% csrf_token %} {{form.as_p}} <input type="submit" name="Submit"> </form> </div>
