Multible dynamic URLs in django
Making a clinic website, in which the user is the clinics, who can then create "patient" objects. To navigate the page, I want the URLs to be dynamic and specific for the clinic and the given patient. Im having trouble making a selecting button on the clinics dashboard. The Dashboard has the following URL: /<str:kl_id>/ . the button should link to a patient page with the URL: /<str:kl_id>/patientside/<str:pt_id>/ The Views.py file looks like this: def klinik(request, kl_id): klinik = Klinik.objects.all() kliniknavn = Klinik.objects.get(navn=kl_id) E_patient = kliniknavn.patient_set.all() context = {'E_patient':E_patient, 'klinik':klinik} return render(request,'DentHelp/klinik.html', context ) I have tried in the template to make the following code, making a list of eksisting patients, with buttons leading to the dynamic patient page: {% for patient in E_patient %} <tr> <td>{{patient.id_nr}}</td> <td>{{patient.fornavn}}</td> <td><a href="{% url 'patientside' kl_id=klinik.navn pt_id=patient.id_nr %}" class="btn btn-primary">Vælg patient</a></td> </tr> {% endfor %} With this code do I get a NoReverseMatch error when trying the klinik page. Looking forward to getting help. -

csrf cookie not set on linux
I know this question is quite popular, before asking it, I researched all the previous questions and their answers, but never found a solution for myself. My problem is that I am trying to remove the csrftoken validation completely in my application. I understand the vulnerabilities that open up in this case, but this is not critical for me. During development, no errors occur on my computer due to csrftoken, I develop on windows, but when I run it on linux, this error appears, it’s hard for me to imagine the reason why this happens only on a linux server, I transfer using docker . I decided to remove csrftoken from my application for the same reason, on the windows computer on which I developed the application, no errors occurred with csrftoken enabled, but when transferred to a linux server, forms using data transfer using js files also gave an error 403. Settings MIDDLEWARE = [ 'django.middleware.security.SecurityMiddleware', 'django.contrib.sessions.middleware.SessionMiddleware', 'django.middleware.common.CommonMiddleware', # 'django.middleware.csrf.CsrfViewMiddleware', ] CSRF_COOKIE_SECURE = False CSRF_COOKIE_HTTPONLY = False I removed in js files csrf_token {# {% csrf_token %}#} I removed in js files headers // headers: {'X-CSRFToken': document.querySelector('[name=csrfmiddlewaretoken]').value}, I added in form attribute action="" <form class="js-edit-event-form" action=""> I already cleared … -

Django ORM: get the monthly average of price for each category
Imagine this simple model: class Expense(models.Model): price = models.DecimalField(decimal_places=2, max_digits=6) description = models.CharField(max_length=300) category = models.CharField(choices=ExpenseCategory.choices, max_length=20) created_at = models.DateField() I'm trying to get the monthly average of price for each category in the current year. My general thought was to do something like: sub = ( Expense.objects.filter(created_at__year=date.today().year) .annotate(month=TruncMonth("created_at")) .values("month", "category") .annotate(total=Sum("price")) .order_by("month") ) qs = Expense.objects.values("category").annotate(avg=Avg(Subquery(sub.values("total")))) I'm basically trying to: Truncate the months of created_at Group by category and month Sum the prices Aggregate the prices for each category It works just fine if I do like: for category in categories: sub.filter(category=category).aggregate(avg=Avg("total")) -

Have tried this as an AJAX post too but still the same, capturing variables but not passing into the database for some reason. Views.py def createResidential(request): if request.method!="POST": return HttpResponseRedirect(reverse("apps:customers.create")) else: residential_firstname=request.POST.get("residential_firstname") residential_lasttname=request.POST.get("residential_lasttname") residential_contact=request.POST.get("residential_contact") residential_mobile=request.POST.get("residential_mobile") residential_email=request.POST.get("residential_email") residential_houseflatno=request.POST.get("residential_houseflatno") residential_houseflatname=request.POST.get("residential_houseflatname") residential_streetname=request.POST.get("residential_streetname") residential_city=request.POST.get("residential_city") residential_county=request.POST.get("residential_county") residential_postcode=request.POST.get("residential_postcode") try: postResidential=ResidentialCustomer( residential_firstname=residential_firstname, residential_lasttname=residential_lasttname, residential_contact=residential_contact, residential_mobile=residential_mobile, residential_email=residential_email, residential_houseflatno=residential_houseflatno, residential_houseflatname=residential_houseflatname, residential_streetname=residential_streetname, residential_city=residential_city, residential_county=residential_county, residential_postcode=residential_postcode, ) postResidential.save() messages.success(request,"Data Save Successfully") return HttpResponseRedirect(reverse('apps:customers.create')) except: messages.error(request,"Error in Saving Data") return HttpResponseRedirect(reverse('apps:customers.create')) Models.py class ResidentialCustomer(models.Model): residential_firstname = models.TextField() residential_lasttname = models.TextField() residential_contact = models.IntegerField() residential_mobile = models.IntegerField() residential_email = models.EmailField() residential_houseflatno = models.IntegerField() residential_houseflatname = models.TextField() residential_streetname = models.TextField() residential_city = models.TextField() residential_county = models.TextField() residential_postcode = models.TextField() residential_dateCreated = models.DateTimeField(default=timezone.now) agent = models.ForeignKey(User, on_delete=models.PROTECT) def __str__(self): return f"{self.residential_firstname} {self.residential_lasttname}" Form in html page <form action="{% url 'apps:createResidential' %}" method="POST" class="vertical-navs-step">{% csrf_token %} <div class="form-floating"> <input type="text" class="form-control" name="residential_firstname" placeholder="John"> <label for="residential_firstname">First Name</label> </div> Same for all other fields I need to capture … -
How can I move Django models to a different django app? I'm not sure the migrage --fake option can work for me since I have 2 cases to consider
In moving models from one django app to another, I used the approach recommended from this question: Moving multiple models from one django app to another class Post(models.Model): title = models.CharField(max_length=120) class Meta: db_table = 'blog_post' However, in my case, I also have some models that need to migrate, in addition to the ones that I'm moving to another app. Since I want some tables to stay intact (the ones migrating to another app), and some others to actually change, then I don't think the migrate --fake is an option I can use. What can I do? -
How to test django using test sqlite3 database instead default mysql database?

Can't hit django views.py function from URL
I'm new to Django-react and having problem in hitting specific function of views.py file using URL. Here is my main project URL file urlpatterns = [ path('admin/', admin.site.urls), path('company/', include('manageCompany.urls')), ] Here it's manageCompany.urls file router = DefaultRouter() router.register('', CompanyViewSet, basename='companies') urlpatterns = [ # path('', index), path('', include(router.urls)), path('saveFile/', SaveFile) ] urlpatterns += static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT) Here's my views.py file class CompanyViewSet(viewsets.ModelViewSet): queryset = Company.objects.all() serializer_class = CompanySerializer @csrf_exempt def SaveFile(request): if request.method == 'POST': file = request.FILES['file'] file_name = default_storage.save(file.name, file) return JsonResponse(file_name, safe=False) return JsonResponse("Hello") Now I'm trying to hit saveFile method from postman using POST method using URL http://127.0.0.1:8000/company/saveFile/ but it's showing "Method \"POST\" not allowed." Where it's going wrong? What should be my URL so that I could hit that SaveFile function? -
Not hashing password. Unexpected keyword argument 'password2'
I have three different questions. They're all related to each other. 1 - I get an error when I add password2 or confirm_password field. Got a `TypeError` when calling `CustomUser.objects.create()`. This may be because you have a writable field on the serializer class that is not a valid argument to `CustomUser.objects.create()`. You may need to make the field read-only, or override the UserCreateSerializer.create() method to handle this correctly. TypeError: CustomUser() got an unexpected keyword argument 'confirm_password' 2 - Without any validate when I only have password field. I am not getting any errors but passwords are not hashed. 3 - When I want to create user using shell. Even if I leave all the fields blank, I can create an empty user without any errors.
