Change is query in ListModelMixin after Django upgrade
I have upgraded my existing project from Django 2.2.26 to 3.2.11 and updated all its dependencies. Using the list method in ListModelMixin after the upgrade yields a different query. My approach has been to check Django changelogs which has not provided me with an answer yet. Is there any other possible reason for this to happen? -
Is it possible to display objects in Django with customized sorting according to categories, just like Pandas dataframes?
Thank you for reading. A large amount of data has been saved through Django objects.save(). In that data, I want to reorder rows with a specific value in a specific column first, and then just float the rest in order. Data objects data category 1 A 2 B 3 C 4 C For example, I want to show category B first, i want to reorder like below. data category 2 B 1 A 3 C 4 C In a pandas dataframe, I can use the sort function after creating a category like below. df['category'] = pd.Categorical(df['category'], ["cate3", "cate4", "cate1","cate2"]) df.sort_values(['category']) But what if I have already saved it as a django object? Django object.save takes a lot of time, so I can't save it after sorting the dataframe. I saved django objects with below codes. ca=pd.read_csv('data.csv') for i in range(0,1000): Product(data=ca.iloc[i].data.astype('float'),category=ca.iloc[i].category).save() Thank you. -
Django tables2 TypeError: Object of type Client is not JSON serializable

How to use a 'dependent_fields' with django easy-select2
I use easy-select2 to set up some dropdown menus. I would like to set up dropdown list that relies on a previously selected field. So after selecting a 'country' I would like the 'city' dropdown menu shows only cities from this country. I assume it should be done creating a new widget with a 'dependent_fields' but I do not succeed to do it.

How do I fill automatically a foreign key on a form of multiple pages in Django? (function based view)
I'm developing a website where the user have to compile a form to start an equipment purchase procedure. In my django website I've created several models with the Foreign Key referred to the principal model which is called MAIN. In particular I have these two models: MAIN and SPECIFICATIONS. SPECIFICATIONS has a foreign key which is ID_request and it connects to the MAIN model. models.py class MAIN(models.Model): ## attributes class SPECIFICATIONS(models.Model): ID_request = models.ForeignKey(MAIN, on_delete=models.CASCADE) Spec = models.CharField(max_length=100, blank=False) CliReas = models.CharField(max_length=100, blank=False) rif = models.IntegerField(default=0, null=False) MinMax = models.CharField(max_length=20, blank=True) I'm structuring the form into two pages, where in the first one the user has to compile some fields of the MAIN model. In the second one I would like to make the user fill 'Spec', 'CliReas', 'rif', 'MinMax' fields, but I want also the ID_request be automatically set to that of the previously entered device. Can you suggest me how I can do it? I'm using function-based views: views.py def new_2_4(request): form = SpecForm() if request.method=='POST': form1 = SpecForm(request.POST) if form1.is_valid(): form1.save() return redirect('/') context={'form1': form1} return render(request, 'new_2_4.html', context) And forms.py class SpecForm(ModelForm): class Meta: model = SPECIFICATIONS fields = ['ID_request', 'rif','Spec', 'CliReas', 'MinMax'] Thank you in … -

Problem with updating and saving object in django-rest-framework
I have a problem with updating and saving object based on frontend input in Django-rest-frameweork. Everything seems to work fine, because this piece of code accually creates an object. The problem is whenever I want to save FE CartItem.amount = 10 this code returns value of 1. I am 100% sure I'm putting correct int value into the url. I am getting user_id, token, product_id and amount from this url: path('add-to-cart/<int:user_id>/<str:token>/<int:product_id>/<int:amount>/', add_item_to_cart, name="add-to-cart"), Then I use this function to either create of update an object: @csrf_exempt def add_item_to_cart(request, user_id, token, product_id, amount): if validate_user_session(user_id, token): user = CustomUser.objects.get(id=user_id) product = ProductStock.objects.get(id=product_id) if product.quantity < amount: return JsonResponse({'error':"You are trying to order more then we can provide!"}) try: existing_item = CartItem.objects.get(user=user, product=product) updated_amount = existing_item.amount + amount if updated_amount > product.quantity: existing_item.save(amount=product.quantity) return JsonResponse({'success':"Product updated in the database!"}) else: existing_item.save(amount=updated_amount) return JsonResponse({'success':"Product updated in the database!"}) except ObjectDoesNotExist: cart_item = CartItem(user=user, product=product, amount=amount) cart_item.save() return JsonResponse({'success':"Product created in the database!"}) else: return JsonResponse({'error':"You need to be logged in for that action!"}) Here are ProductStock and CartItem objects: class CartItem(models.Model): name = models.CharField(max_length=50, blank=True, null=True) user = models.ForeignKey(CustomUser, on_delete=models.CASCADE) product = models.ForeignKey(ProductStock, on_delete=models.CASCADE, blank=True, null=True) amount = models.IntegerField(default=0, blank=True, null=True) size = … -
Excluding a custom field from admin create object
Like here, I want to make a field only visible when editing the already existing object: I have a straight forward admin: @admin.register(Store) class StoreAdmin(admin.ModelAdmin): from = StoreAdminForm ... and I have a form with an extra field: class StoreAdminForm(forms.ModelForm): img = forms.ImageField() ... Now I want to exclude img when creating a new object. I tried extending the StoreAdmin class by: def add_view(self, request, extra_content = None): self.exclude = ("img",) return super().add_view(request) but this has no effect - I guess this just does not work on manually created fields? -
Correct approach to big model with no user accounts
I want to create django+react app that does not utilize user accounts in any way but it collects a lot of user input in a single page. Is there any way to allow user to look into his input a day later? Can i just store the object in cookies? Or can I save sessionid and load model when user refreshes website? Also- it will be like a big form saved to a single object. Is it good idea to create such a big model? For example- user provides whether or not does he have a windows in his room. If so he writes which wall is it on, it's height, width, distance from left corner, width of sill. Should it be a new model called, idk WindowConfig or something like that? It will be more readable but on the other hand it complicates serializers. -
Python requests verify certificat in production

form.instance doesn't populate field
I have the following form for creating a user: class CreateAccount(UserCreationForm): class Meta: model = USER fields = ['first_name','last_name','username','email','employee_id','is_active','is_staff'] and it's view: class CreateAccountView(CreateView): model = USER form_class = CreateAccount template_name = 'createaccount.html' def form_valid(self, form): form.instance.employee_id = Employee.objects.get(username=self.kwargs.get('username')) return super().form_valid(form) def get_success_url(self): return reverse('People') I used form.instance to pass it an employee object, but it doesn't work and I get 'This field is required.

Django - Generic Relations
I have a website with different kinds of activities: Lessons ; Exercises ; Quizzes. So far, each type of activity corresponds to a specific Model and a table in the database. I would like to create an ordered path through these activities. For instance: Lesson 1 then Exercise 1 then Lesson 2 then Quizz 1 etc. I am considering to create a model named Activity that would store the following data: A number: the number of the activity in the path ; A One-To-One relationship to one given activity (lesson, exercise, quizz etc.). (1) I have seen that Django offers a GenericForeignKey to handle many-to-one relationship to different kinds of models, like many comments associated to a single lesson or a single exercise. Is there something similar for Generic OneToOne relationship? (2) I would like to track the progress of my users. To do so, I am considering having a many-to-many relationship called "done_activities" built in my User model and linked to my Activity model. Do you think this is an efficient way of approaching the problem ? -

How to get highest bid for every item in an auction bidding site Django
So I have a Django auctions app, which has 3 models: Users, Listings, Bids. When a user tries to place a bid on some listing, I want to check if the new_bid field in Bid model is bigger than start current_bid field in Listing model and if the new_bid is <= 0, it should return a message. This is what I've done so far but when I click on 'Place bid' button, it does not implement this (it does not show any message for any of the above scenario and my count does not increase) meaning that the form is not submitting. Why is this not working?
