Django Module Object is Not Callable Problem
I'm struggling to fix an error that doesn't allow me to access my /api/lead/ URL, as I keep getting an error "module object is not callable. Within my DjangoApp project, I have one other folder named api, and one other folder with the standard name of the project, which in my case is "DjangoApp". api/models.py : from django.db import models # Create your models here. class Lead(models.Model): name = models.CharField(max_length=100) email = models.EmailField() message = models.CharField(max_length=300) created_at = models.DateTimeField(auto_now_add=True) api/LeadListCreate.py : from .models import Lead from api import LeadSerializer from rest_framework import generics class LeadListCreate(generics.ListCreateAPIView): queryset = Lead.objects.all() serializer_class = LeadSerializer api/LeadSerializer.py : from rest_framework import serializers from .models import Lead class LeadSerializer(serializers.ModelSerializer): class Meta: model = Lead fields = ('id', 'name', 'email', 'message') api/urls.py : from django.urls import path from . import views urlpatterns = [ path('api/lead/', views.LeadListCreate.as_view() ), ] DjangoApp/urls.py : from django.contrib import admin from django.urls import path, include urlpatterns = [ path('admin/', admin.site.urls), path('', include('api.urls')), ] -
Secure Websocket and https with Django [closed]
I am working with a Django development server in version 4.0.1 which uses an SSL certificate (https). The application uses websockets and there is the problem: it doesn’t work. Please note that the use of websockets works without SSL certificates. I’ve read that all you have to do is change “ws://” to “wss://” but that doesn’t seem to be enough. Do you have an idea? Thanks, MLP. -
How do I Filter a viewlist based on a selection made on a createview form? Django
I am learning how to use Python & Django. I don't have much experience, and this has been a huge learning process for me. Please forgive any ignorance in my question. I am designing a Django app and have a few relational tables created. My question involves only my first 2 models/forms/views. Here are my models ` class CustomerName(models.Model): #Fields company = models.CharField(max_length = 60, help_text = "Enter Customer Name",unique=True) def __str__(self): return self.company class ProgramName(models.Model): #Fields customer = models.ForeignKey("CustomerName",on_delete=models.CASCADE) program = models.CharField(max_length = 60, help_text = "Enter Program Name") def __str__(self): return self.program ` Here are my Views (Ive left out the customer add view since that works and I don't think its relevant) ` class ProgramAddView(CreateView, ListView): template_name = 'app/ProgramAdd.html' form_class = Programform model = ProgramName success_url = reverse_lazy('Part Number Add') def get_context_data(self, **kwargs): context = super().get_context_data(**kwargs) context["qs_json"] = json.dumps(list(ProgramName.objects.values())) return context ` Here is the form ` class Programform(forms.ModelForm): class Meta: model = ProgramName fields = "all" class Customerform(forms.ModelForm): class Meta: model = CustomerName fields = ('company',) ` Here is the HTML app/ProgramAdd.html ` {% extends 'base.html' %} {% block content %} <h2>Program</h2> <form method="post" class = 'formarea'> <div id = 'formarea' class = 'formdiv'> {{ form.media.js … -
BooleanField Model not showing the default False value
I have a model class where the variable completed_application should default to False when creating a new user (to show that the user hasn't completed an application yet). However, by default when a new user is created it doesn't show as False in Django admin but '-' instead. models.py: class Completed(models.Model): class Meta: verbose_name_plural = 'Completed Application' user = models.OneToOneField(settings.AUTH_USER_MODEL, on_delete=models.CASCADE) completed_application = models.BooleanField(default=False) admin.py: class Company(admin.StackedInline): model = Completed can_delete: False verbose_name_plural = 'Completed Application' class UserAdmin(UserAdmin): list_display = ('username', 'first_name', 'last_name', 'email', 'company', 'completed') search_fields = ('username', 'email',) inlines = [Company] list_filter = ('is_active',) fieldsets = ( (None, {'fields': ('username', 'password')}), (('Personal info'), {'fields': ('first_name', 'last_name', 'email')}), (('Permissions'), { 'fields': ('is_active', 'is_staff', 'groups',), }), (('Important dates'), {'fields': ('last_login', 'date_joined')}), ) The red arrow in the first image above points to the Users admin panel for a newly created user. The second image shows the individual user in Django admin with the custom model added to that user. Other point to note: Checking the box and saving the user it shows True (as to be expected), but then unchecking the box and saving the user it eventually shows False and not '-'. Could someone explain what this '-' means … -
Partial update to extended user profile
I have a extension to user model in Django, adding multiple fields to the regular user profile. In order for the user to be able to change them, I have created a form that should be able to modify those fields but with no success... models.py class UserProfileModel(models.Model): user = models.OneToOneField(User, null=True, on_delete=models.CASCADE) agency_name = models.CharField(max_length=255, null=True) license_number = models.CharField(max_length=10, null=True) phone = models.CharField(max_length=10, null=True) phone2 = models.CharField(max_length=10, null=True) fax = models.CharField(max_length=10, null=True) address = models.CharField(max_length=255, null=True) city = models.CharField(max_length=255, null=True) zip_code = models.CharField(max_length=10, null=True) about = models.CharField(max_length=255, null=True) # חפ pi_id = models.CharField(max_length=10, null=True) reason_pension = models.CharField(max_length=255, null=True) reason_policy = models.CharField(max_length=255, null=True) reason_gemel = models.CharField(max_length=255, null=True) reason_hishtalmot = models.CharField(max_length=255, null=True) def __str__(self): return str(self.user) class Meta: ordering = ('user',) forms.py class UserProfileChangeForm(forms.ModelForm): customer_name = forms.CharField( widget=forms.TextInput( attrs={ "placeholder": "שם לקוח", "class": "form-control" } )) labelwhite = forms.CharField( widget=forms.TextInput( attrs={ "placeholder": "", "class": "form-control" } )) smoker = forms.CharField( widget=forms.TextInput( attrs={ "placeholder": "מעשן", "class": "form-control" } )) ensurence_amount = forms.CharField( widget=forms.TextInput( attrs={ "placeholder": "ביטוח חיים", "class": "form-control" } )) ensurence_amount1 = forms.CharField( widget=forms.TextInput( attrs={ "placeholder": "00000", "class": "form-control" } )) disability_amount = forms.CharField( widget=forms.TextInput( attrs={ "placeholder": "נכות מתאונה", "class": "form-control" } )) class Meta: model = LifeEnsurenceModel fields = ('customer_name', … -

asyncio loop blocking django http and websocket requests

How does token based authentication work?
I implement a web application (with Python+Django - to the extent that matters). Users can log in normally with username and password, but in addition I want to provide an API which users use to script the interaction with my site. For the API authentication my plan was to do something like this: In the database I create table with 'tokens' - i.e. random strings which point to the user database. The user gets a token string. For every API call the user passes the token string along with their request In the API implementation the code: Verify the token. Log the correct user in and execute the API function as the user matching the token. Log the user out again. Return the result Does this make sense? On the one hand it seems very simple - on the other hand it feels quite homemade, something I have heard is not recommended when it comes to security related topics? -

Django validation error from nested serializer
Inside a run_validation method I am calling another serializer's is_valid(raise_exception=True). If the input is not valid to the other serializer, then the program fails with the following error. super().__init__(*args, **kwargs) ValueError: need more than 0 values to unpack Here goes the code: def run_validation(self, data): modules = data.getlist("modules", []) if "modules" in data else [] if len(modules) > 0: sm_ser = SMSerializer(data=modules, many=True) sm_ser.is_valid(raise_exception=True) return super(CSSerializer, self).run_validation(data) Question 1. Is it ok to call validation for another object like this in this method? Question 2. How to make the run_validation raise the errors that are coming from the other serializer. sm_ser.errors is a list of errors which is not coming through.

How to exclude html from js export to xlsx with ExcellentExports.js?
Thanks in advance! In case it helps I am using Django3 and Python3 for the backend and javascript, html, and css for the front end. I am also using ExcellentExport.js to export html tables to excell. It works great with one caveat. It is exporting the entire html page instead of the two ids I specified. the html code snip of the tables to be exported: <div id="table1" class="position-absolute text-nowrap" style="max-width: 300px; max-height: 50px; right: 1600px; top: 145px;"> {% render_table tableP18 %} </div> <div id="table2" class="position-absolute" style="max-width: 100px; max-height: 10px; right: 1300px; top: 365px;"> {% render_table tableP17 %} </div> My js: function export() { return ExcellentExport.convert({ anchor:this, filename:'data_123.array',format: 'xlsx'}, [ {name: 'filename1', from: {table: 'table'}}, {name: 'filename2', from: {table: 'table2'}} ]); } What I'm trying to figure out is how to exclude certain html elements from the export in either the html or in js. Please let me know if you need any more information or code! -

models in django. is many to many the best option?
I am trying to make my first website with django. Basically I'm making a website to check the bus schedule in my rural area. I think that the best thing is to make two models, one where all the bus stations are defined and the other where the route is established, for each route two stations are needed (origin and destination). I was wondering what was the best way to relate the two models. class BusStations(models.Model): bus_stations = models.CharField(max_length=80) bus_stations_identifier = models.IntegerField() def __str__(self): return self.bus_stations class Routes(models.Model): origin_station = models.ManyToManyField( BusStations, related_name='origin_station') destination_station = models.ManyToManyField( BusStations, related_name='destination_station') data = models.JSONField() slug = models.SlugField(unique=True, null=True) def __str__(self): return f'{self.origin_station} - {self.estacion_destino}' For now I was doing it with ManytoMany relationships, but this is giving me problems. For example, I am not able to return the origin and destination stations as str in the route model. I would also like it to be the slug. Thanks for advance. -

Multiple django databases and queries
good work. I have a database connection structure as follows. DATABASES = { 'default': { 'ENGINE': 'django.db.backends.postgresql_psycopg2', 'NAME': 'DATA', 'USER': 'postgres', 'PASSWORD': 'root', 'HOST': '127.0.0.1', 'PORT': '5432', }, "big_data": { "ENGINE": "mssql", "NAME": "DATABASE_NAME", "USER": "USER_NAME", "PASSWORD": "PASSWORD", "HOST": "HOST_ADDRESS", "PORT": "1433", "OPTIONS": { "driver": "ODBC Driver 17 for SQL Server", }, }, } I need to fetch and display data via mssql. And this, `from django.db import connections with connections['big_data'].cursor() as cursor: cursor.execute("SELECT * FROM [aab].[CENTER]")` but the page load is delayed. To get this with django orm python manage.py inspectdb --database=big_data > models.py i run it gives a blank output. It says on the internet that it doesn't receive it because of the database schema. How can I get around this how can I get it on django orm just to write a query. Page load speed is very good in queries performed with Django orm. Also, when I create the model file manually, it adds the application name to the beginning of the table and I can't ask what I did. This is a problem for me. The database I connect belongs to a different system, so I can't interfere too much because I only have the … -
Django create or update model only if field not equal to certain value
We have a potential race condition where multiple users can try to create or update a record. Wondering if there's a way to create a column, than when set (to say true), then an exception will be thrown, preventing the update. The underlying database is postgres, but since we're using django to wrap it, we would like to limit ourselves to something django offers, and not mess with very specific database settings. Thanks! -

Transform python requests's exceptions to django-rest-framework's API exceptions
I'm developing a REST API using django-rest-framework that needs to interact with a 3rd party API. I use requests for comunication with this 3rd party API. Some recurrent pattern I get in my code is making a request from an APIView handler def calculate_order(order): url = f"https://api.anotherservice.com/orders/calculate/" try: response = requests.post(url, json=order.data) response.raise_for_status() # TODO: handle errors, just printing and re-raising for now except requests.exceptions.HTTPError as errh: raise errh except requests.exceptions.ConnectionError as errc: print(errc) raise errc except requests.exceptions.Timeout as errt: print(errt) raise errt except requests.exceptions.RequestException as err: print(err) raise err return response.json() # ... In my view def post(self, request, *args, **kwargs): # ... Some preprocessing code here order_calculated = calculate_order(order) return Response(order_calculated, status=HTTP_200_OK) DRF implements a mechanism that hanldes Subclasses of APIException raised inside REST framework. Django's Http404 exception. Django's PermissionDenied exception. I was wondering if there's a package for transforming requests's exceptions to exceptions objects that DRF can handle. Also I'll be glad to know any recomendation on how this should be implemented (best practices). I was googling it but terms with "Django" and "requests" drop results mostly of Django itself. -
