Getting type error when passing model in select tag in Django
I have a model called Department it has data College and HS, when I try to save my form I always get a TypeError. I've tried to validate the form and found out that it was an unbound form so I tried changing the Field type of department from ChoiceField to CharField and in my templates I tried calling {{form.department}} and it gives me the correct data yet it still gives TypeError. views.py class editProfile(UpdateView): model = Profile form_class = UpdateUserForm template_name = 'accounts/profile.html' success_url = reverse_lazy('homepage') #TypeError or ValueError def get_context_data(self, **kwargs): context = super().get_context_data(**kwargs) context['initial']=Profile.objects.get(user=self.request.user) context['department']=Department.objects.all() context['program']=Program.objects.all() context['year']=Year.objects.all() return context def form_valid(self, form): user = form.save(commit=False) user.username = form.cleaned_data.get('username') user.profile.department = form.cleaned_data.get('department') user.profile.program = form.cleaned_data.get('program') user.profile.year = form.cleaned_data.get('year') user.profile.save() user.save() forms.py class UpdateUserForm(forms.ModelForm): def __init__(self, *args, **kwargs) -> None: super(UpdateUserForm, self).__init__(*args, **kwargs) self.fields['username'].label = 'Username' self.fields['department'].label = 'Department' self.fields['program'].label = 'Program' self.fields['year'].label = 'Year' username = forms.CharField(widget=forms.TextInput(attrs={ 'class': 'form-control', 'placeholder': 'Type your username' })) department = forms.CharField(widget=Select(attrs={ 'class': 'form-control' })) program = forms.CharField(widget=Select(attrs={ 'class': 'form-control', }, )) year = forms.CharField(widget=Select(attrs={ 'class': 'form-control', }, )) class Meta: model = User fields = ['department', 'program', 'year', 'username'] models.py class Department(models.Model): department=[ ('HS','Highschool Department'), ('College','College Department') ] name = models.CharField(_('Department'),max_length=50,choices=department) def … -
Django form creator
I am building a Django project which let users(teachers) create Forms for their students. they can add inputs and also options (for dropdown inputs). I solve this challenge by using dictionaries (I store their inputs and options in dictionaries and if they add options elements will be added to their keys as lists) I don't like the way that I am storing data (as dictionaries) in my database. I want to know if there are any features in Django that can let me produce module fields for my database. in short- I want to handle the database (create new fields) in my view. -
Iterate through non-queryset dictionary in a template
I have a dictionary that I am feeding into a chart.js line chart. It looks as follows: context['graph_data'] = {'day': [datetime.date(2022, 2, 28), datetime.date(2022, 3, 1), datetime.date(2022, 3, 2), datetime.date(2022, 3, 3), datetime.date(2022, 3, 4), datetime.date(2022, 3, 5), datetime.date(2022, 3, 6), datetime.date(2022, 3, 7), datetime.date(2022, 3, 8), datetime.date(2022, 3, 9), datetime.date(2022, 3, 10), datetime.date(2022, 3, 11), datetime.date(2022, 3, 12), datetime.date(2022, 3, 13), datetime.date(2022, 3, 14), datetime.date(2022, 3, 15), datetime.date(2022, 3, 16), datetime.date(2022, 3, 17), datetime.date(2022, 3, 18), datetime.date(2022, 3, 19)], 'response_totals': [0, 0, 0, 0, 12, 12, 1, 0, 0, 0, 0, 0, 0, 0, 0, 0, 1, 0, 0, 0]} The template section that I am getting tripped up on looks like the following: new Chart(ctx1, { type: "line", data: { labels: [{%for i in graph_data%}{{i.day}},{%endfor%}], datasets: [{ label: "Referrals", tension: 0.4, borderWidth: 0, pointRadius: 2, pointBackgroundColor: "#cb0c9f", borderColor: "#cb0c9f", borderWidth: 3, backgroundColor: gradientStroke1, data: [{%for j in graph_data%}{{j.response_totals}},{%endfor%}], maxBarThickness: 6 }, I am a bit of a newbie. I can handle querysets but I'm not sure how to transform non-qs dictionaries via the template. -

Running Django management commands in Visual Studio with .env file environment variables
I need to remove all sensitive keys from the code in my Django app, even those keys that are just used for local testing. The Visual Studio debugger can load environment variables from a .env file. I followed the official tutorial and it's worked, the dev server runs and my Django app can access environment values that are stored in the .env file. But I've hit an issue when I run custom Django management comments. Is there a way to run the commands from the debugger so that they can also access the environment variables? Or some other way to run the commands so they can access the key-value pairs in the .env file? -

Django model queryset order objects in the same order as how they appear in filter_horizontal box
I am having trouble in figuring out how to query for objects in Django model, so that the queried results are exactly as how objects appear in the selected filter list. Let me explain this more clearer. We assume I have two models, one called TakeawayWebshop and one called Product. A TakeawayWebshop can sell many products, but when the customer views the product page, I want the product to appear in the order that I have included them in the filter box. In models.py class TakeawayWebshop(models.Model): name = models.CharField(max_length = 255, help_text = 'name of takeaway restaurant') products = models.ManyToManyField(Product) class Product(models.Model): name = models.CharField(max_length = 50, unique=True) description = models.TextField() price = models.DecimalField(max_digits=9, decimal_places=0, default=0.00) class Meta: ordering = ['-created_at'] In the admin.py I have added product in filter_horizontal. Is it possible to obtain a query set of product that is added to the TakeawayWebshop in the same order as how they appear in the filter_horizontal? Also currently, it is not possible to move the product up or down in the filter_horizontal box from admin. Is there a clever way to implement this feature? class TakeawayWebshopAdmin(admin.ModelAdmin): form = TakeawayWebshopAdminForm list_display = ['name'] ordering = ['name'] filter_horizontal = ('products',) admin.site.register(TakeawayWebshop, … -

Django Q objects in model constraints
I am trying to extend a model in an Django App. The only problem I have is that I need to extend the model constraints as well and that does not work properly. This is the original constraint for the object in models.py: models.CheckConstraint( check=( models.Q(inventory_item__isnull=True, device_type__isnull=False) | models.Q(inventory_item__isnull=False, device_type__isnull=True) ), name="At least one of InventoryItem or DeviceType specified.", ) I have tried to extend it like that: models.CheckConstraint( check=( models.Q(inventory_item__isnull=True, device_type__isnull=False, module_type__isnull=False) | models.Q(inventory_item__isnull=False, device_type__isnull=True, module_type__isnull=False) | models.Q(inventory_item__isnull=False, device_type__isnull=False, module_type__isnull=True) ), name="At least one of InventoryItem, ModuleType or DeviceType specified.", ), This is how this looks in the migration: migrations.AddConstraint( model_name='hardwarelcm', constraint=models.CheckConstraint(check=models.Q(models.Q(('device_type__isnull', False), ('inventory_item__isnull', True), ('module_type__isnull', False)), models.Q(('device_type__isnull', True), ('inventory_item__isnull', False), ('module_type__isnull', False)), models.Q(('device_type__isnull', False), ('inventory_item__isnull', False), ('module_type__isnull', True)), _connector='OR'), name='At least one of InventoryItem or ModelType or DeviceType specified.'), ) My problem is that I tried all combinations and it fails every time, but I can see from the error message that only one value is set and the other are Null. DETAIL: Failling row contains (3, null, 1, null) Is there some limitation with Q objects that I don't understand? I have tried to read the Django documentation, but could not figure out what the problem is. -

Increment id within a parent entity in Django model
I have this problem where I have a parent model User that is one-to-many linked to another model say Device. What I want to do is within each user, I want to create and increment an id for each device he own. Something like user A have two devices so his user_device_id will be 1 and 2. user B have one device so his user_device_id will be 1. vice versa. I have a current working solution but I am looking for an alternative solution. The Device model currently implemented which overrides save method: class Device(models.Model): user = models.ForeignKey(User, on_delete=models.CASCADE) user_device_id = models.PositiveIntegerField(default=0, null=false) def save(self, *args, **kwargs): try: within_user_device_id = Device.objects.filter(user=self.user).latest('user_device_id').user_device_id self.user_device_id = within_user_device_id + 1 except Device.DoesNotExist: self.user_device_id = 1 For the neater method, in my mind, to create a function that gets the current instance of user and use the default in models.PositiveIntegerField to increment this value. The problem is I cannot get refer the current instance and call the function in default. class Device(models.Model): def increment_within_user_device_id(self): within_user_device_id = Device.objects.filter(user=self.user).latest('user_device_id').user_device_id if not within_user_device_id: return 1 else: within_user_device_id += 1 return within_user_device_id user = models.ForeignKey(User, on_delete=models.CASCADE) # I cannot pass the function in default user_device_id = models.PositiveIntegerField(default=increment_with_user_device_id(self), null=false) Any … -
Django: Old url is still searched after POST request
I am fairly new to Django and now at my wit's end with the following issue. I have changed the url name from 'odata' to 'database' and the app properly redirects to the url http://127.0.0.1:8000/database/. However while being at http://127.0.0.1:8000/database/ and making the POST request using ajax, the app freezes and on looking in the browser's developer tools I see the error: Page not found (404) Request Method: GET Request URL: http://127.0.0.1:8000/odata/ . . . The current path, odata/, didn't match any of these. Why the old name is still being searched? I have made changes in the following files and codes: my_app/url.py urlpatterns = [ path('', views.view1, name = "view1"), path('database/', views.view2, name = "view2"), #old name was odata/ ] myreq.js function submit_training() { $.ajax({ url: '/database/', //earlier- /odata/ data: $('form#db_settings').serialize(), method: 'POST', ... } When I revert the changes to 'odata' everything works as expected. I am not sure what I am missing here. I apologize for not providing more or exact codes, as I am not supposed to disclose details on the project. However, I can still furnish more information, if required. Your time and help is much appreciated!! -

DjangoRestFramework: Assign CustomUser failed
Good evening, inside my djano-application I've created a custom user... class CustomUser(AbstractUser): username = None email = models.EmailField(_('email address'), unique=True) USERNAME_FIELD = 'email' REQUIRED_FIELDS = [] objects = CustomUserManager() def __str__(self): return self.email ...and added the following code snippet into settings.py: AUTH_USER_MODEL = 'app_something.CustomUser' My Question: how can I add it into the following - let's say - put request: ... elif request.method == 'PUT': serializer = SomethingSerializer(qs, data=request.data) if serializer.is_valid(): serializer.save(user_created=request.user) # --> line that causes the error return Response(serializer.data, status=status.HTTP_201_CREATED) return Response(serializer.errors, status=status.HTTP_400_BAD_REQUEST) ... Right now I'm trying to add the request.user, which fails with the error something_user_created" must be a "CustomUser" instance. My first idea was to add the CustomUser like this, but I dont't know how to get the active user inside my view: from app_something.models import CustomUser customuser = CustomUser.objects.get(id=???) ... serializer.save(user_created=customuser) ... Does anyone know what I'm doing wrong here? Thanks for you help and have a great day! -
