How to include foregin key attribute in Elastic Search Django?
I have two models Products and VendorProducts model as follows : class Product(models.Model): brand = models.ForeignKey(BrandName,related_name="brand_products", on_delete=models.CASCADE) item_name_title = models.CharField(max_length=10000) class VendorProducts(BaseModel): product = models.ForeignKey(Product , on_delete=models.PROTECT , null=True ,related_name="vendor_products") vendor_selling_price = models.FloatField(default=0, null=True, blank=True) Now I want to add this VendorProduct model in ElasticSearch. And I have done something like this @registry.register_document class ProductDocument(Document): product = fields.ObjectField(properties={ "item_name_title" : fields.TextField()}) class Index: name = "vendor_products" class Django: model = VendorProducts fields = [ "id", ] related_models = [Product] def get_queryset(self): """Not mandatory but to improve performance we can select related in one SQL request""" return super(ProductDocument, self).get_queryset().select_related( 'product' ) First, this is how we add the foreign key model in Elastic search. Now the issue is I am not able to get any of the results. Although I can see the results in elastic search when I tryto access it by port 9200 I can see the search results. But when querying I am getting empty responses. This code I am using s = ProductDocument.search().query("match", description=search) -

DRF-Spectacular with django-split-settings: AssertionError: Incompatible AutoSchema to generate Swagger
I am encountering an error when utilizing django-split-settings (version 1.3.0) and drf-spectacular (version 0.27.1) in my Django project. The error occurs when attempting to access the Swagger UI endpoint at api/schema/swagger-ui/.

I am new in Stack overflow and I am getting problem during deleting product from cart In my cart.html: <button class="btn btn-sm btn-remove delete-item" data-item="{{product_id}}"><i class="fas fa-trash-alt" ></i></button> This is the delete button I created. Now also I created js for this button so in my cart.js: console.log("Hi"); $(document).on("click", '.delete-item' ,function(){ let this_val=$(this) var _pID=$(this).attr('data-item'); console.log(_pID); $.ajax({ url: '/delete-from-cart', data: { 'id': _pID, }, dataType: 'json', beforeSend: function(){ this_val.hide() }, success: function(response){ this_val.show() $(".cart-items-count").text(response.totalcartitems) $("#cart-list").html(response.data) } }) }) for the js file when i am clicking on the delete button I am getting product ids as output I also created a views for it.

Django: How to get data from html? How to make a value of int increases overtime? How to stop a button from working when that value matches 100?
im working on a project of a web game with Django. The main idea is that the player has a continuous increasing infection meter. He would need to scan mutiple qr code (representing a location, like the game city hunt), to decrease his infection. If it reaches 100, he would become a zombie and a button will be blocked or hide. -To acheive this, I'm having some ideas but i don't know know exactly how i should implement it. Here are the challenges: 1.How to get data from html to my database?(I uses SQLite) -I want to recieve data from the html (the qrcode will turn into points (a -ve value) and i need to add that to the player To decrease his infection rate) 2.How to make a value of int increases overtime? I want to add an dynamicinfection attribute to the player,so that it increase through time(like the Enlightenment meter in Don't starve if you know what i mean lol ) . Should i mainly be coding the timer and the value in html and java script or I should code in python (django)instead? Where should i build the timer thing? 3.How to stop a button from working … -
View returning user as None
So, I'm creating a user confirmation system where a code is created, stored in the session and send through email I made some prints inside the view that is used to confirm the code and active the user, the code is this one: def activeThroughCode(request,): form = VerificationForm() if request.method == 'POST': form = VerificationForm(request.POST) if form.is_valid: entered_code = request.POST.get('verification_code') stored_code = request.session.get('verification_code') print("Entered Code:", entered_code) print("Stored Code:", stored_code) username = User.objects.get('username') if entered_code == stored_code: print(username) try: user = User.objects.get(username=username) user.is_active = True user.save() messages.success(request, f'Your account is active with success.') return redirect('login') except User.DoesNotExist: messages.error(request, 'Incorrect verification code.') return redirect('login') else: messages.error(request, f"It wasn't possible to confirm your email") return render(request, 'activate.html',{'form': form}) When digiting the code in my form, I can confirm through terminal the entered code and stored code are the same, and everything is ok until here but, for validating my user, I need, obviously, request the user to active and save it, but the result for username = User.objects.get('username') if entered_code == stored_code: print(username) is None.

Utilizing Poppler and Django in Digital Ocean App
I am having issues with Poppler playing nice with the DigitalOcean Apps. I have a Django Web App that I have built and I have an automation script that I want to run. This script takes the text file reads the file and then puts the contents into a db field for a user text search function. It will work on my local machine, but it will not run. I get a PDFInfoNotInstalledError. In researching that error it states that Poppler is not installed and will need to be installed. Digital Ocean will not let you do an apt install from the console. I created an aptfile to install poppler. I was asked by DO support to add it in the requirement.txt file. I did that and added the path to the $PATH variables. Still was getting the same error. Unsure on what to do next can someone help me with this issue? I have tried to add poppler to the server, I have tried adding a python package for poppler. I was expecting for this to be recognized so that the OCR tool could work. -

Trouble Deleting Items from Cart Using AJAX In Django
I am new in Stack overflow and I am getting problem during deleting product from cart In my cart.html: <button class="btn btn-sm btn-remove delete-item" data-item="{{product_id}}"><i class="fas fa-trash-alt" ></i></button> This is the delete button I created. Now also I created js for this button so in my cart.js: console.log("Hi"); $(document).on("click", '.delete-item' ,function(){ let this_val=$(this) var _pID=$(this).attr('data-item'); console.log(_pID); $.ajax({ url: '/delete-from-cart', data: { 'id': _pID, }, dataType: 'json', beforeSend: function(){ this_val.hide() }, success: function(response){ this_val.show() $(".cart-items-count").text(response.totalcartitems) $("#cart-list").html(response.data) } }) }) for the js file when i am clicking on the delete button I am getting product ids as output I also created a views for it. So, In my views.py: def delete_item_from_cart(request): product_id=str(request.GET['id']) if 'cart_data_obj' in request.session: if product_id in request.session['cart_data_obj']: cart_data=request.session['cart_data_obj'] del request.session['cart_data_obj'][product_id] request.session['cart_data_obj'] = cart_data cart_total_ammount=0 if 'cart_data_obj' in request.session: for p_id, item in request.session['cart_data_obj'].items(): cart_total_ammount += int(item['qty']) * float(item['price']) context= render_to_string("core/async/cart_list.html", {"products":products}, {"data":request.session['cart_data_obj'],'totalcartitems': request.session['total_cart_items'] ,'cart_total_ammount':cart_total_ammount}) return JsonResponse({"data": context, 'totalcartitems': request.session['total_cart_items'] ,'cart_total_ammount':cart_total_ammount}) and then In urls.py: path("delete-from-cart/", delete_item_from_cart,name="delete-from-cart"), this is my url Note: At last I would say that I made a cart page where all the products are displaying which are sellected. and I connected cart-lsit.html with cart.html by main tag with id you can see this in the … -

How to set BinaryField to primary key in django?
