Django ValueError - not enough values to unpack (expected 2, got 1) list of tuples error
This is what is causing the error, I know that much: forms.py file: class CustomSignupForm(UserCreationForm): ENGLISH_INTEREST = EnglishInterest.get_english_interest_data() english_interest = forms.MultipleChoiceField(choices=ENGLISH_INTEREST, widget=forms.CheckboxSelectMultiple()) models.py file: class EnglishInterest(models.Model): english_interest = models.CharField(max_length=255) def get_english_interest_data(): return EnglishInterest.objects.values_list('english_interest') I know there must be some simple solution to get this multiple choice field to work. It does work if I were to use instead: ENGLISH_INTEREST= [ ('general speaking', 'General Speaking'), ('work opportunities', 'Work Opportunities'), ('travel', 'Travel'), ('study abroad', 'Study Abroad'), ] -
DRF Token Authentication: { "detail": "Authentication credentials were not provided." }
I am working on a Django e-commerce project. I tried to implement a token authentication system. I added rest_framework.authtokento INSTALLED_APPS and REST_FRAMEWORK = { 'DEFAULT_AUTHENTICATION_CLASSES': ( 'rest_framework.authentication.TokenAuthentication', ), 'DEFAULT_PERMISSION_CLASSES': ( 'rest_framework.permissions.IsAuthenticated', ) } to settings file.

Now, I should be able to access any API provided I add Authorization HTTP header in this format. Authorization:Token "xyz" But I keep getting {"detail":"Authentication credentials were not provided"} Here is the view I am trying to access. class SubcategoryView(APIView): def get(self,request): serializer=SubcategorySerializer(Subcategory.objects.all(),many=True) return JsonResponse({"subcategories":serializer.data}) Why do I keep getting this error?

How to implement autocomplete_fields with Proxy model?
I want to implement autocomplete_fields feature but it doesn't work. I assume it happens because of Proxy model. So I have Customer Proxy model and PromoCode model. PromoCode has FK to Customer model. And I need to have search field for customers in PromoCode change form. Here are models and admin classes: class Customer(User): # User is a class based on django.contrib.auth.models.AbstractUser class class Meta: proxy = True class CustomerAdmin(admin.ModelAdmin): search_fields = ['email',] admin.site.register(Customer, CustomerAdmin) class PromoCode(TimeStampedModel): customer = models.ForeignKey(Customer, on_delete=PROTECT, null=True, blank=True) class PromoCodeAdmin(admin.ModelAdmin): autocomplete_fields = ('customer',) admin.site.register(PromoCode, PromoCodeAdmin) There are no errors but Customer field is still default Select input without desired filter.

Django Inlineformsets - Custom validation with django-extra-views
So I have a question about the form_valid for django-extra-views. I used the CreateWithInlinesView method to create a form with multiple inline formsets. The base form called "Order" contains two different formsets, "Booking" and "Payment". An Order always has to include a minimum of one Booking but does not necessarily need to have a Payment when the Order is created. The form for the Payment will be generated nonetheless. I would like to validate the Payment form on a "payment_amount" > 0. If no payment is made at the moment the order is created, no PaymentInline should be saved. views.py class BookingInline(InlineFormSetFactory): model = Booking form_class = BookingForm prefix = 'booking_formset' factory_kwargs = { 'extra': 0, 'min_num': 1, 'validate_min': True, 'can_delete': True } class PaymentInline(InlineFormSetFactory): model = Payment form_class = PaymentForm prefix = 'payment_formset' factory_kwargs = { 'extra': 1, 'min_num': 0, 'validate_min': False, 'can_delete': True } class OrderCreateView(NamedFormsetsMixin, CreateWithInlinesView): model = Order inlines = [BookingInline, PaymentInline] inlines_names = ['booking_formset', 'payment_formset'] form_class = OrderForm template_name = 'orders/order_form.html' def get_success_url(self): return reverse_lazy('order_detail', kwargs={'pk': self.object.pk}) def forms_valid(self, form, inlines): """ If the form and formsets are valid, save the associated models.

How to interpret this parsing error of the image variable that was rendered in the django template in heroku?
The error says (ImageFieldFile' object is not subscriptable) I wanted to call an image url using an image variable in the html django templates.

Change admin form name for overridden User
I've overridden the standard django User by extending AbstractUser. Now this all works fine, but for some reason I can't make the admin display "Profiles" (the name of the model now set in settings.AUTH_USER_MODEL instead of "Users". This is my code for admin.py for the profiles app from django.contrib import admin from django.contrib.auth.admin import UserAdmin from django.contrib.auth.forms import UserChangeForm from .models import Profile class ProfileChangeForm(UserChangeForm): class Meta(UserChangeForm.Meta): model = Profile verbose_name_plural = "Profile" class ProfileAdmin(UserAdmin): form = ProfileChangeForm # fieldsets = UserAdmin.fieldsets + ((None, {"fields": ("some_extra_data",)}),) fieldsets = UserAdmin.fieldsets admin.site.register(Profile, ProfileAdmin) I'd figured there should be some Meta setting I can put in here, but after significant amounts of googling I can't find anything. I'm sure this is a simple answer - could somebody point me in the right direction? I've tried setting "name" and "verbose_name", but no joy. At the end of the day, I could live with this, as it's just the admin interface, but it's bugging me ... -

gunicorn keeps rebooting it's worker when Django is starting Python project
I am running a web-based project with a data science focussed backend which is hosted on a Microsoft Azure cloud server. Large deep learning models need to be loaded and initialized when Django starts the project. I am running the project through an nginx server which communicates to the Django server through gunicorn. If I run the project on the same Azure cluster through Django alone (not using nginx or gunicorn) it initializes and starts just fine.

Overwriting nested serializer's create method throws TypeError: create() got multiple values for keyword argument
