Django UpdateView creates duplicated formsets
I'm having problems when updating the entries of my products, discounts and inventory in the database, the inventories and discounts have the product id as a foreign key and I have defined two inline formsets to enter all the data in one single form ProductMeta=forms.inlineformset_factory(Product,Inventory,InventoryForm,extra=0,can_delete=False) DiscountMeta=forms.inlineformset_factory(Product,ProductDiscount,DiscountForm,extra=0,can_delete=False) Something strange happens, both formsets work normally when creating using extra=1 in the formsets, but in the UpdateView I must use extra=0, otherwise the inventory and discount forms get duplicated, and both forms disappear from the creation view views.py class UpdateProduct(UpdateView): model=Product form_class =ProductForm template_name = 'new_product.html' title = "UPDATE PRODUCT" def get_context_data(self, **kwargs): context = super(UpdateProduct, self).get_context_data(**kwargs) if self.request.method == 'POST': context['product_meta_formset'] = ProductMeta(self.request.POST,instance=self.object) context['discount_meta_formset'] = DiscountMeta(self.request.POST,instance=self.object) else: context['product_meta_formset'] = ProductMeta(instance=self.object) context['discount_meta_formset'] = DiscountMeta(instance=self.object) return context def form_valid(self, form): context=self.get_context_data() productMeta=context['product_meta_formset'] discountMeta=context['discount_meta_formset'] if productMeta.is_valid() and discountMeta.is_valid(): self.object=form.save() productMeta.instance=self.object productMeta.save() discountMeta.instance=self.object discountMeta.save() if not productMeta.is_valid(): print("productMeta invalid") if not discountMeta.is_valid() : print("discountMeta invalid") return redirect(reverse("products:listProducts")) For some reason Django considers that my productMeta and discountMeta are invalid since both prints are executed and obviously the changes are not saved in the database, for now I fix the inlineformset extra=0 problem using other inlineformsets, but I would like to know how to solve the invalid … -
(Hidden field id) Select a valid choice. That choice is not one of the available choices. (Django)
I'm receiving this error when I try to submit two formsets. After I fill the form and click the save button, it gives the error: (Hidden field id) Select a valid choice. That choice is not one of the available choices. I'm trying to create dynamic form so that the user can add new sections and also new lectures inside the section when they click "Add" button. The adding new form function works well, I just have problem saving it to the database.

Rebuilding a PyQt5 Desktop App for the web? with Python/Django
I have created a PyQt5 Desktop App but I've decided I want it as a webpage instead. So, to do this I think I'm going to completely remake the app using Django/python. My app is essentially 1 page of around 100 buttons that output midi notes when clicked. I would like to see exactly the same layout of buttons and CSS on a webpage as I currently do on my Desktop App and need to have the buttons call functions, just as they do on the desktop app. Essentially I need to translate my PyQt5 Desktop app to a Webpage and need help understanding how to start, thanks. -

ORM vs Raw Queries (For big project)
I am working on a project which I want to eventually launch to the public. In past, I have Used Django which uses ORM to use databases as python models. But I also know that they add extra overhead in terms of latency and query optimization. But now I am using FastAPI as my restapi server, PSQL as DB and I have to use 3rd party ORM such as SqlAlchemy (which is really complex). I am thinking of two choices Start with ORM initially, and later move to raw queries if there is a performance issue or high demand of users. Start with raw SQL initially using psycopg2 library. If I go with this, I have to manage everything such as connection pooling, queries, and if conn breaks reconnect it etc. Is there any python famous lib that can do that on top of psyopg2. I wanted to know if there is increase in app consumers how to tackle database queries. How do the big companies like facebook, amazon, Instagram do this? I am sure they are not using ORMs. -
django Model object.all() for ModelChoiceField and ModelMultipleChoiceField
I have a TransactionCategory model and I want to use it to display both ModelMultipleChoiceField and ModelChoiceField in django form. model.py class TransactionCategory(models.Model): """ Transaction Category database model """ txn_category = models.CharField("Transaction Category", max_length=50, null=True, default=None, blank=True) def __str__(self): """ Transaction Category Returns: transaction category : str """ return f"{self.pk} ({self.txn_category})" class Meta: verbose_name = "Transaction Category" db_table = "txn_category" forms.py queryset fills the MultipleChoiceField control using "id" as value and "txn_category" as text perfectly. class TxnCategoryDetailModelForm(forms.ModelForm): txn_description = forms.ModelMultipleChoiceField(label="Transaction Description", queryset=CreditCardTxnDescription.objects.all().order_by("description"), required=False, widget=forms.CheckboxSelectMultiple) class Meta: model = TransactionCategory fields = ["txn_category"] Doesn't work well with ModelChoiceField (dropdown), the queryset populates the id correctly but text shows "id (txn_category)" e.g. "1 (food)" class TxnDescriptionTagsModelForm(forms.ModelForm): description = forms.CharField(widget=forms.TextInput(attrs={"autofocus": "autofocus"}), strip=False) txn_category = forms.ModelChoiceField(queryset=TransactionCategory.objects.all().order_by('txn_category')) tags = TagWidget() class Meta: model = CreditCardTxnDescription fields = ["description", "description_comment", "txn_category", "tags"] How can I use TransactionCategory model for both ModelMultipleChoiceField and ModelChoiceField and have them displayed properly? -
The best way for calculated fields in Django
I'm starting to create my first web application in Django. I'm dealing with backEnd part first. In my data structure I need to calculate some fields like average rating of employee's salary for each model object (company, department ..). I found some ways to calculate and display calculated field in API. Add a property into model and override querySet for better performance. Calculate and add extra field in serializers and display it for API. Use build-in computedfields.models I can not decide which way is best for calculating fields, what are pros and cons of each way. Thanks for some advice. -
Best way to create an 'online virtual piano' webpage?
I want to create a basic online midi piano webpage. I know Python very well but not JavaScript yet. What is the best way to do this? Is Django or Flask relevant here? Essentially I just want a super basic midi piano on a webpage and am just looking for a point in the right direction, thanks. Context: I have made a PyQT5 Desktop App but have now decided I want it as a webpage so I need to completely remake it. I've never done any web development. I need Midi and not audio files. -
json.dumps serialized query set into unusable format in Django with WebSockets (Channels)
I read everything I could found about serializing QuerySets in Django but still can not find any working solution for transferring the existing WSGI function into a ASGI WebSocket Consumer. My view function looked like this: ... context = { "registered": user_is_player, "object": game, "player": player, "players": game.player_set.all(), "players_cards": players_cards, "card_deck": game.globalcarddeck_set.all(), "prio_deck": game.prioritydeck_set.all(), "table": game.table_set.all(), "cards": game.card_set.all(), } return render(request=request, template_name=template_name, context=context) and was working fine, but the query results sadly seam not to be transferable via synchronous web socket. Within my class GameConsumer(WebsocketConsumer) I figured that I can transfer a single result with with model_to_dict (after sadly loosing a few fields) but same does not apply to QuerySets. Those can be only serialized with the serialize function like: serialize("json", game_instance.player_set.all()). ... game_instance = Game.objects.get(slug=self.game_name) game_json = model_to_dict( game_instance, fields=["name", "slug", "round_number", "active", "started"] ) context = { "registered": user_is_player, "game": game_json, "player": player, "message": message, "players": serialize("json", game_instance.player_set.all()), "players_cards": serialize("json", players_cards), "card_deck": serialize("json", game_instance.globalcarddeck_set.all()), "prio_deck": serialize("json", game_instance.prioritydeck_set.all()), "table": serialize("json", game_instance.table_set.all()), "cards": serialize("json", game_instance.card_set.all()), } self.send(text_data=json.dumps({"context": context})) At the end everything needs to be dumped with json.dumps, otherwise one would end up with the exception: self.sendMessage(content.encode("utf8"), binary) AttributeError: 'dict' object has no attribute 'encode' This seam to be the … -

Cant include navbar.html in other modules
I'm quite a beginner in web development I've encountered some problems using Django this is my projects modules code. {% include 'navbar.html' %} <h1>projects template</h1> <p>Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book. It has survived not only five centuries, but also the leap into electronic typesetting, remaining essentially unchanged. It was popularised in the 1960s with the release of Letraset sheets containing Lorem Ipsum passages, and more recently with desktop publishing software like Aldus PageMaker including versions of Lorem Ipsum. </p> {% endblock content %} and this is my navbar.html: <h1>Logo</h1> <hr> when I run this, it is expected to return something like this: enter image description here but it instead outputs this: enter image description here as you can see it doesn't wrap the navbar text correctly. I would really appreciate it if someone helps me with this issue. -
Always get None from Django api request as result
I am going to get whitebg_url result from sqlite database according to matched items and made the api request using django like this. @api_view(['POST']) def getUrlFromAttributes(request): try: print('>>>>>>>>>>>>>>>>>>>>>', request) hairstyle = request.data.get("hairstyle") haircolor = request.data.get("haircolor") skincolor = request.data.get("skincolor") print("error>>1", str(hairstyle), str(haircolor), str(skincolor)) basic_query = BasicSetup.objects.all().filter(skin_color=skincolor, hair_color=haircolor, hair_style=hairstyle, isDeleted= 0) print('returned basic queyr : ', basic_query) lists_basicSetup = list(basic_query.values( 'whitebg_url')) print('returned lists_basicSetup : ', lists_basicSetup) return JsonResponse({'result': lists_basicSetup}) except Exception as error: print("error", str(error)) return JsonResponse({'result': str(error)}) But as you can see the result at the below image, response is always None. I tried to find the solution from google, but can't do it. I already add rest_framework at INSTALLED_APPS in settings.py file. and path is like defined. path('getUrlFromAttributes', views.getUrlFromAttributes, name='getUrlFromAttributes'), I tried to do this using Postman, but the result was same.

Temporary data storage in django which is persistent across browser
I'm building a Django where the admin will create a user and then one mail will be sent to the user. In the mail, I'm also sending one token with the URL on clicking which the user will get verified by checking the correctness of the token. But the problem is I'm storing the token in Django session and when I open the link on the same browser it works but on a different machine user is not getting verified as session data becomes unavailable. Someone suggest me the best way to store the token. I didn't want to use the database as it doesn't make sense. -
