Validationerror: "choose a valid option" on related field in ModelForm
I have a Model Inserzione related to a Model Servizio: class Inserzione(models.Model): servizio = models.OneToOneField( 'hub.Servizio', on_delete=models.CASCADE, null=True, default=None, related_name='+' ) In my InserzioneModelForm I want to restrict the choices of Servizio, I don't want all Servizio instances to be included. So in my InserzioneModelForm __init__ method: query = self.fields['servizio'].queryset self.fields['servizio'].queryset = query.filter(# my condition) This works correctly, when the user is submitting a form only the Servizio instances I want are available in the form field. The problem is that the form_valid() method returns False. It return a ValidationError {'servizio': [ValidationError(["Choose a valid option. The selected option is not between the available ones"])]} But it's actually an existing and valid Servizio instance. Here the incriminated form field in my template: <div class="controls "> <select name="servizio" class="select form-control" required="" id="id_servizio"> <option value="" selected="">---------</option> <option value="1">Corso Sicurezza sul Lavoro</option> <!--other options--> </select> </div> Any help is really aprreciated, thanks. -

Django. How to not repeat yourself using class based views?
I'm new to Django. I wonder if it is considered 'repeating yourself' when I use generic views such as CreateView, ListView and etc. in different apps and they differ in values for attributes like 'model', 'fields' or 'template_name' only? Do I repeat myself in this case or I shouldn't be worried? -
Django - Group by and do ArrayAgg
I have a model: class Deviation(models.Model): deviation_number = models.SmallIntegerField() day_of_calculation = models.SmallIntegerField() And I'd like to group records of the model by day_of_calculation and get list of deviation_numbers: deviations = Deviation.objects \ .values('day_of_calculation') \ .annotate(deviation_numbers=ArrayAgg('deviation_number')) But Django incorrectly creates sql: SELECT "deviation"."day_of_calculation", ARRAY_AGG("deviation"."deviation_number" ) AS "deviation_numbers" FROM "deviation" GROUP BY "deviation"."day_of_calculation", "deviation"."deviation_number" Grouping by deviation_number should not happen. What do I do wrong? -

Why hide a django secret key?
I wanted to ask, why should I hide the secret key in a Django application? Why not just commit it to public source control? I understand the effects of an attacker finding out the secret key (from here). But if I just upload the code to github and ask people to download it, run python manage.py runserver and go to 127.0.0.1:8000, I don't need to hide it, right? Don't those effects of revealing the secret key apply for when you run the code on your device using your device as a server, and have them visit it at a public URL? If they're running it on their own device, that doesn't pose a security risk to me, right? I read that knowing the secret key can allow them to bypass form validations, etc. But they would just be messing up the db of their own local installation of the app so why should I care? -
Displaying table x's fields in GET request of table y that has foreign key of table x (Django)
I could use some help please, been stuck on this for awhile. I have two tables, Share and Fund. Share.py class Share(models.Model): ShareName = models.CharField(max_length=100, unique=True, default="N/A") ISINCode = models.CharField(max_length=100, primary_key=True, default="N/A") Fund.py class Fund(models.Model): FundID = models.AutoField(primary_key=True) FundName = models.CharField(max_length=100, default="N/A", unique=True) FundIdentifier = models.CharField(max_length=100, default="N/A") PercentOfFundNetAssets = models.DecimalField(decimal_places=2, max_digits=5, default=0.00) ISINCode = models.ForeignKey(Share, to_field='ISINCode', related_name="toshares", on_delete=models.CASCADE) class Meta: unique_together = ('FundIdentifier', 'ISINCode') Individually they has been no issue for GET/POST/PUT etc. Its important now though that on GET requests to fetch the fund table while also retrieving the relevant share fields that fall under each fund row. See below: What fund JSON looks like now upon GET request [ { "FundName": "Some fund", "FundIdentifier": "FND001", "PercentOfFundNetAssets": "3.82", "ISINCode": "SHR001" }, ] What I want fund JSON to look like upon GET request [ { "FundName": "Some fund", "FundIdentifier": "FND001", "PercentOfFundNetAssets": 3.82, "ISINCode": "SHR001", "share": [ { "ISINCode": "SHR001", "ShareName": "Some share" } ] } ] I'd also settle for something like this though. [ { "FundName": "Some fund", "FundIdentifier": "FND001", "PercentOfFundNetAssets": 3.82, "ISINCode": "SHR001", "ISINCode": "SHR001", "ShareName": "Some share" } ] Either way, each fund json object will only have one share object within with its relevant fields … -

Issue with Django redirect to previously visited page
I am trying to update the login view. For now, if someone will try to enter http://127.0.0.1:8000/articles/ then the user is redirected to http://127.0.0.1:8000/ (login page) and after successful log, it is redirected to http://127.0.0.1:8000/home. What I want is to redirect users to the page they tried to visit before logging in. So if someone will try to visit http://127.0.0.1:8000/articles then after log in the website should redirect him to the articles page, not to home. This is what I tried: views.py class UpdatedLoginView(LoginView): form_class = LoginForm template_name = 'user/login.html' redirect_field_name='main/homepage.html' def post(self, request): form = self.form_class(request.POST) if form.is_valid(): if 'next' in request.POST: return redirect(request.POST['next']) login.html <form method="post" class="login-form background" novalidate> {% csrf_token %} {{ form|crispy }} {% if request.GET.next %} <input type="hidden" name="next" value="{{request.GET.next}}" /> {% endif %} <button type="submit" class="text-center mx-auto border-0 join-btn col-sm-12 col-md-6 main-btn">Login</button> <a href="{% url 'login' %}?next={{request.get_full_path|urlencode}}">Login test</a> // this is just a test element, I want to have button in my form </form> My question is how to modify UpdatedLoginView and form in order to redirect users to previously visited page. The code I tried is taken from here.
