Django forms.Form reflecting property field constraints
I'm implementing a Django Form witch should contain the field 'fieldA' from modelA: class ModelA(models.Model): fieldA = models.CharField(max_length=8) ... My question is: Is there a way to have Django form, which will automatically handle validation of fieldA (check the max_length)? I know I Could use form.ModelFormclass referring to ModelA, but then the form would reflect all the fields of the ModelA. I would like to use simple forms.Form. I'm looking for a solution like: class formX(forms.Form): fieldA = forms.CharField(**modelA.fieldA.constraints) fieldB = ... some other fields not related to ModelA ... .... even more fields -
Django Rest Framework for Calculations
I'm starting to develop in django/django rest framework and I needed to make a kind of calculator, send a and b, python would take these values, process, for example, do the sum and return in a json, but I only find examples with database data, would it be possible to do this? -
Django Middleware Login check
I want to restrict all pages for unauthenticated users. I wrote the following middleware: from django.shortcuts import redirect def require_login(get_response): def middleware(request): if request.user.is_authenticated: response = get_response(request) return response return redirect('/login/') return middleware The issue is that it also redirects to my Login page when it redirects to Login page (hope you got it). So it continuously redirects to my login page. What do I need to do about it? Is it okay to check if the requested page is Login page then don't check the if statement above. Thanks! -

How to Reassign value to variable in Django template through filters
I have an xml object that I am looping to print in template. It is detailing of items with their tax rate. so after printing all items I need sum of those tax rate values. I am trying to sum up that value in template. I have created filter named updatevariable, it is working and doing sum up but issue is due to loose of old sum it just returns latest value rather than whole sum up. SO I need a way to reassign TotalTax with sum up value from filter. this is example of output needed: Tax-1 16 Tax-2 18 Tax-3 2 TotalTax = 36 {% with TotalTax=0 %} {% if taxRateDetailing %} {% for item in taxRateDetailing%} <tr> <td> {{item.1.text}} </td> <td> {{item.4.text}} {{TotalTax|updatevariable:item.4.text}} </td> </tr> {% endfor %} <tr> <td> Total Tax </td> <td> {{TotalTax}} </td> </tr> {% else %} <tr> <td> Tax </td> <td> {{defaultSalesTaxRate}} </td> </tr> {% endif %} {% endwith %} Filter function def updatevariable(value, arg): TotalTax = value + float(arg) return TotalTax -

How do I display a Django form correctly using ListView
I am writing a simple app to track sales leads based on the Django tutorial "Writing your first Django app" (https://docs.djangoproject.com/en/4.0/intro/tutorial01/). Everything works well except for displaying a ListView of the existing leads. Here are the relevant python snippets: # leads/models.py class Leads(models.Model): id = models.IntegerField(primary_key=True) last = models.CharField(max_length=32) first = models.CharField(max_length=32) # config/urls.py urlpatterns = [ # Django admin path('admin/', admin.site.urls), # User management path('accounts/', include('allauth.urls')), # Local apps path('leads/', include('leads.urls')) # leads/urls.py app_name = 'leads' urlpatterns = [ path('', LeadsListView.as_view(), name='list'), path('<int:pk>/', LeadsDetailView.as_view(), name='detail'), ] # leads/views.py class LeadsListView(ListView): model = Leads template_name = 'leads/list.html' context_object_name = 'leads_list' def get_queryset(self): return Leads.objects.order_by('id') class LeadsDetailView(DetailView): model = Leads template_name = 'leads/detail.html' The link in the 'home.html' template, which displays a menu option correctly: <a href="{% url 'leads:list' %}">Leads</a> And finally, the 'list.html' template that does not display at all. Instead of showing the list of leads, it remains on the home page. {% block content %} {% for lead in lead_list %} <div class="lead-entry"> <h2><a href="{% url 'leads:detail' lead.pk %}">{{ lead.fname }} {{ lead.lname }}</a></h2> </div> {% endfor %} {% endblock content %} I'm missing something fundamental here.... -

How to implement JWT access mechanism for a Django application (not django rest_framework)
I'm actually looking for a way to implement. I have a django project folder (only django, not django rest framework). All the views across all the apps in the project will be returning a JsonResponse parsed response. (Instead of rendering to a template) A basic view looks like this, with necessary imports from django.views.decorators.csrf import csrf_exempt from django.views.decorators.http import require_http_methods from django.http import JsonResponse @csrf_exempt @require_http_methods(['POST']) def sample_route(request): # validate request object, use them to query / process data # .. some more statements result = {"a": 1, "b": 2} return JsonResponse(result, status=200) I understand that this isn't a conventional practice like in a DRF project, but I would like to make such routes accessible by tokens (supposedly JWT). Can I get suggestions about how this would be possible - like with or without depending on djangorestframework library or any extensions or any other JWT associated libraries. Thanks -
Join with OneToOneField relathionship django
I have two models with OneToOneField relationship and I want to somehow join them and be able to access the attribute of the one model from the other. My models.py is as follows: from django.db import models from django.contrib.postgres.fields import ArrayField from django.contrib.auth import get_user_model CustomUser = get_user_model() class Event(models.Model): user_id_event = models.ForeignKey(CustomUser, on_delete=models.CASCADE, null=True) created_at = models.DateTimeField(auto_now_add=True, null=True) dr_notice_period = models.IntegerField(blank=True, null=True) dr_duration = models.IntegerField(blank=True, null=True) dr_request = models.FloatField(blank=True, null=True) class Result(models.Model): event_id_result = models.OneToOneField(Event, on_delete=models.CASCADE, null=True) HVAC_flex = ArrayField(models.FloatField(blank=True, null=True)) DHW_flex = ArrayField(models.FloatField(blank=True, null=True)) lights_flex = ArrayField(models.FloatField(blank=True, null=True)) My views.py is as follows: @api_view(['GET']) def result(request): results_list = Result.objects.all() num_results_list = Result.objects.all().count() if num_results_list < RES_LIMIT: serializer = ResultSerializer(results_list, many=True) query = serializer.data return Response(query) else: results_list = Result.objects.order_by('-created_at')[:RES_LIMIT] serializer = ResultSerializer(results_list, many=True) query = serializer.data return Response(query) Right now the query is as follows: [OrderedDict([('id', 1), ('HVAC_flex', [49.0, 27.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0]), ('DHW_flex', [4.0, 0.0, 45.0, 4.0, 20.0, 33.0, 42.0, 13.0]), ('lights_flex', [6.0, 8.0, 0.0, 0.0, 0.0, 18.0, 28.0, 0.0]), ('event_id_result', None)]), OrderedDict([('id', 2), ('HVAC_flex', [0.0, 0.0, 15.0, 0.0, 23.0, 6.0, 0.0, 0.0]), ('DHW_flex', [1.0, 2.0, 7.0, 47.0, 1.0, 19.0, 37.0, 9.0]), ('lights_flex', [40.0, 28.0, 34.0, 6.0, 8.0, 43.0, 6.0, 0.0]), ('event_id_result', None)]), OrderedDict([('id', …
