How to save static/class variables in Django
Since Django loads its code dynamically, I am currently facing the problem of not being able to use class variables. My intention: I wanted to run a few threads that repetitively do the same thing over and over again. However, the threads should only exist once. That's why I collected them in a dictionary. Problem: The dictionary is reset again and again, because Django constantly reloads code. The question now is: How can I solve this cleverly? This is the Wrapper module with thread & abstract parent class. If you want a spcecific task you have to inherit from here: class TaskThread(Thread): def __init__(self, delay_time: timedelta = None, repeat_time: timedelta = None, task: Callable = None, thread_name: str = None, daemon=None, *args, **kwargs): super().__init__(name=thread_name, daemon=daemon, args=args, kwargs=kwargs) self.sleep_time = delay_time if repeat_time is None: raise ValueError('No repeat interval given') else: self.repeat_time = repeat_time if task is None: raise ValueError('No task given') else: self.task = task self.next_execution: Optional[datetime.datetime] = None def run(self): if self.sleep_time: time.sleep(self.sleep_time.total_seconds()) del self.sleep_time self.execute_task() def execute_task(self): self.next_execution = self.__calculate_next_execution__() time.sleep(self.repeat_time.total_seconds()) self.task() self.execute_task() def get_next_execution(self) -> datetime.datetime: return self.next_execution def __calculate_next_execution__(self) -> datetime.datetime: current_time = timezone.now() return current_time + self.repeat_time REPEATING_TASKS: Dict[str, TaskThread] = dict() class RepeatingTasks(ABC): TIME_ZONE … -
Edit multiselect field?
So I have a ManyToMany field in my model and Django admin renders it as a multiselect field. It works fine and I have no issues — except that I can't Edit it after creating a record. I tried Del key, mouse right-click, nothing worked. Looks like I have to delete the record and create it again? This is the field I want to edit. I want to remove one or two of the above items. I'm on Windows. -
Django: Session_key generate new key every time the function is called
I'm using Django-rest-framework views.py: @api_view(['GET']) def addToCartForSession(request, pk): product = get_object_or_404(Product, pk=pk) if not request.session.exists(request.session.session_key): request.session.create() mycart, __ = Cart.objects.get_or_create(session_key=request.session.session_key) mycart.product.add(product) return Response({'response':'ok'}) When this function is called, it create a new key. and for new key, it create a new Cart. But every single user should have only one cart. So, How can I stop creating new session_key for a single user? but one session_key will be created if there is no session_key. how can i do that? also I want to add that: @api_view(['GET']) def addToCartForSession(request, pk): print(request.session.session_key) #>>> None return Response({'response':'ok'}) when I make this, It prints None. -
Querying a database and returning checkboxes for each result
My goal here is to implement the following behavior in the simplest, most future-proof, and most django-y way possible. Other people will have to use and modify this webapp in the future, though it's also somewhat of a learning project for me. Right now, it feels sort of hack-ey, and I'm trying to learn django, and produce something easy to use and modify if needed. Here's the behavior I currently have. The user queries a database and gets a list of words back. There's a special word (or series of them) called a lemma and some others that are called variants. The lemma is in a special sticky box at the top of the list. After the user selects the words they want, they can then do another search from this list of selected words. My question is: have I implemented this correctly? I've made no use of forms, mostly just HTML, and I'm concerned I'm not using django to its full potential. For example, I've looked into forms and FormSets but I'm not quite sure how to use them here, or if they will make my life any easier. I'm attaching the relevant parts of my code so you … -
Okta Authentication Django redirect

Can UUIDField be used as default_auto_field in Django 3.2.^?
I have been using UUIDField as my primary key in Django. My project has a hierarchy of models with inherited fields, and at the top, I have the following superclass: import uuid from django.db import models class HasIDMixin(models.Model): id = models.UUIDField(primary_key=True, default=uuid.uuid4, editable=False, unique=True, name='id') After updating to Django 3.2.4, I get the following warning: WARNINGS: app_base.MyProject: (models.W042) Auto-created primary key used when not defining a primary key type, by default 'django.db.models.AutoField'. HINT: Configure the DEFAULT_AUTO_FIELD setting or the AppBaseConfig.default_auto_field attribute to point to a subclass of AutoField, e.g. 'django.db.models.BigAutoField'. Following the advice of the warning, I tried both the DEFAULT_AUTO_FIELD in settings.py and the default_auto_field in the app_config and I get the following error: ValueError: Primary key 'django.db.models.UUIDField' referred by DEFAULT_AUTO_FIELD must subclass AutoField. I have seen others approach this problem with a custom child class to both UUIDField and AutoField (https://code.djangoproject.com/ticket/32577) but no working solution has been posted. Is this currently possible in Django 3.2.^? If not should I find a different primary key solution or roll back? -
Weasyprint django - generates an empty PDF
Good afternoon, I have the following problem in my app: I am working on generating pdfs via WEASYPRINT for some of my views. My app is a search engine that aggregates external information, what I am looking for is: That the user makes a search and the results are shown. When he clicks on report, he can download a pdf with the search results. (via AJAX without having to reload the page). So far this works perfect using xhtml2pdf, but I want to change it to WEASYPRINT because it allows more flexibility in the design of the pdf. As I said there is an ajax function that sends the data to the pdf generation view, it receives them and generates a pdf with converting the html to pdf and sends a response that with a ".done()' function in javascript activates the download of the pdf. The problem is that this pdf is shown empty because there must be some decoding problem, or so I think. Views.py def ViewPDF(request, *args, **kwargs): response = request.POST.get('nombre', None) hits = request.POST.get('hits', None) response2 = request.POST.get('query1', None) info = {'searched': str(response2), 'customer': request.user.customer.name, 'type_of_search': '', 'lists_covered': 'OFAC', 'Date_of_search': str(request.POST.get('date', None)), 'hits': hits} if response is … -
Using select_related in django view increases query times
I thought of trying to use select_realted in Django view to boost the performance. And I compare the results before using select_realted and after using it. Although I see the reduction of significant number of queries, the time however rises. So I am not sure whether to use select_related in every view or not use them. I just want to know when to use them and when not to. My view is : Before: class ProductAPIView(ListAPIView): permission_classes = [AllowAny] serializer_class = ProductSerializer queryset = Product.objects.all() After: class ProductAPIView(ListAPIView): permission_classes = [AllowAny] serializer_class = ProductSerializer #queryset = Product.objects.all() queryset = Product.objects.select_related('merchant','brand','collection','sub_category') pagination_class = CustomPagination My models: class Product(models.Model): merchant = models.ForeignKey(Seller,on_delete=models.CASCADE,blank=True,null=True) category = models.ManyToManyField(Category, blank=False) sub_category = models.ForeignKey(Subcategory, on_delete=models.CASCADE,blank=True,null=True) brand = models.ForeignKey(Brand, on_delete=models.CASCADE) collection = models.ForeignKey(Collection, on_delete=models.CASCADE) featured = models.BooleanField(default=False) # is product featured? The images before and after the use of select_related. After: Here we can see that the number of queries are reduced to 124, but the time is increased to 227. So, should i be using select_related? When to use it or when not to use it?? -
Django custom form validator won't raise an exception when validation fails

How to check if object in list in Django Views

I successfully registered from React app(front-end) and saved the key (Got from server) in local storage. here is my code: signupHandler=()=>{ fetch('http://127.0.0.1:8000/api/rest-auth/registration/', { method: 'POST', headers:{ 'content-type':'application/json', }, body:JSON.stringify({ 'username':this.state.username, 'email': this.state.email, 'password1': this.state.pass1, 'password2': this.state.pass2 }) }) .then((response)=>{ response.json().then((result)=>{ if (result.key !== undefined){ localStorage.setItem('login', JSON.stringify({login: true,token:result.key})) this.setState({registered: true}) } }) }) } I made a method , which will do this.setState({addedToCart: true}), if the result = 'response':'ok'. here is the method: addToCart=()=>{ var id = this.props.id let store = JSON.parse(localStorage.getItem('login')) console.log(store.token);//successfully print the key var url = 'http://127.0.0.1:8000/addToCart/'+id+'/' fetch(url,{ method:'GET', headers: { 'Content-Type': 'application/json', 'Authorization': 'Token '+store.token } }).then(res=>res.json().then(result=>{ if(result.response === 'ok'){ this.props.dispatch({ type: 'itemInCart', }) this.setState({addedToCart: true}) } })) } and in Django(views.py): @api_view(['GET']) @permission_classes((IsAuthenticated,)) def addToCart(request, pk): product = get_object_or_404(Product, pk=pk) mycart, __ = Cart.objects.get_or_create(user=request.user) mycart.product.add(product) return Response({'response':'ok'}) but it shows >>>the server responded with a status of 403 (Forbidden) I know Django is saying I'm un-authenticated. but why i'm un-authenticated? (where i send the token/key to the server). so, How can I get the response:ok? how can i make me authenticated? -
Python, django: all objects in form works fine except only one
On website page user select 'flight_date', 'flight_number', 'suburb', 'no_of_passenger' on the form and hit summit button. after that, views.py calculate the price with those information and send them back to webiste page (html). all objects appear on webpage as User selected but only 'price' does not appear. 'price_cal()' works fine (I did test it - simple function). I don't know what the problem is... no error message come out. only price does not appear. it says "None" Here are the codes at views.py from django.shortcuts import render, redirect from .area import suburbs def price_detail(request): if request.method == "POST": flight_date = request.POST.get('flight_date') flight_number = request.POST.get('flight_number') suburb = request.POST.get('suburb') no_of_passenger = request.POST.get('no_of_passenger') def price_cal(): if flight_number == 'Drop off To airport': return int(suburbs.get(suburb)) + (int(no_of_passenger) * 10) - 10 elif flight_number == 'Pickup from airport': return int(suburbs.get(suburb)) + (int(no_of_passenger) * 10) price_cal() price = price_cal() return render(request, 'basecamp/price_detail.html', {'flight_date': flight_date, 'flight_number': flight_number, 'suburb': suburb, 'no_of_passenger': no_of_passenger, 'price': price}, ) else: return render(request, 'basecamp/price_detail.html', {}) I am now struggling with this matter for several days... please help me or any hint, much appreciated. -
How to deploy Docker project(Django,nginx,gunicorn) to Production environment
I'm currently developing an application using Django, Nginx, Gunicorn, Postgresql, and Docker. I've created a simple project that just displays a welcome page of Django. I can check the display and operation in the local server(0.0.0.0/), but I cannot check the display and operation if I start the project in the production environment(remote server)（）...

SQL join that happens in the view of Django Rest Framework
I just want to know what type of SQL join is happening in the following view. I read about types of SQL joins but I am not able to figure out what is happening here. class WishListItemsView(ListAPIView): permission_classes = [IsAuthenticated] serializer_class = WishListItemsCreateSerializer def get_queryset(self): user = self.request.user return WishListItems.objects.filter(owner=user) My models: class WishListItems(models.Model): owner = models.ForeignKey(User, on_delete=models.CASCADE,blank=True) #wishlist = models.ForeignKey(WishList,on_delete=models.CASCADE, related_name='wishlistitems') item = models.ForeignKey(Product, on_delete=models.CASCADE,blank=True, null=True) wish_variants = models.ForeignKey(Variants,on_delete=models.CASCADE, related_name='wishitems') I can see it in Django debug toolbar, but it is authenticated so I cant see the quries. -
