How to use global variables in django
I use django_rest_framework. I need parse huge xml file then find some data. Parse xml on get call is bad idea because is too long time. I try once a 3 minute parse it and save parsed object to global variable. But I'm not sure about it work correctly. Example: class MyView(APIView): catalog = None parse_time = 0 @classmethod def get_respect_catalog(cls): if time.time() - cls.parse_time > 300: cls.catalog = parse_xml() cls.parse_time = time.time() return cls.catalog def get(self, request): vals = catalog.xpath('tag/text()') # here i find some tag ... return response I sent several requests but many time variable parse_time had value 0. As if class MyView recreate sometimes and class variables "catalog" and "parse_method" resets to init values. I think it because uwsgi have many workers and many interprets. May be exists way for using global variables in django. P.S. I know for my case I need use database. But I want use global vars. -

Django object creation happens infinitely
I have a class connectTo defined in myclass.py which will connect to lets say a TCP socket and importing the same in views.py. I wrote an ajax to call the views function which creates object for my class as below views.py from myclasses import connectTo def connect(request): connectTo() return JsonResponse("Success") but the problem is as long as django server is running the connection to the TCP socket is happening. It should happen only once when connect in views.py is called instead it keeps on creating object and establishes TCP connection and stops if I close django server. -
Django admin inlines - how to remove empty records from create/update form
I'm using StackedInline to add related objects in my Django admin form (relation is one to many). The problem is that it renders three empty inline forms by default when creating new object like in this example: What I want is to render only "Add" button because the related objects are so rare that most of the records don't have these (or at least single empty record) and my related object is much larger than the one on the pictures. It should look something like this example: How can I do this? -

How to implement Biometric Authentication in a ReactJS Web Application
I currently have a web application set up using ReactJS for the front-end, Django and Apache Guacamole for the back-end and MariaDB for the database. I also have a Secugen Hamster Plus Fingerprint Scanner which when plugged in to the computer, will be used for user authentication on the login page of the web application (using ReactJS). Does anyone know how I can go about writing code to retrieve fingerprint images from the database to compare them with the user-inputted fingerprint when he attempts to login? I have been unsuccessful in finding any working examples or documentation for reference on the Internet. -
How to get type of object if value of ForeignKey is None?
I have got a basic foreign key table structure class Category(models.Model): id_pk = models.AutoField(primary_key=True) label = models.CharField(unique=True, max_length=200, blank=True, null=True) class Meta: managed = False db_table = 'category' and class PartProperty(models.Model): id_pk = models.AutoField(primary_key=True) category = models.ForeignKey(Category, models.DO_NOTHING, blank=True, null=True) class Meta: managed = False db_table = 'part_property' If a row inside PartProperty has a Category object I can access this object via e.g. part_property = PartProperty.objects.select_related().filter(id_pk=part_property_id) and part_property[0].catogory respectively dynamically via part_property .values(*(self.__COLUMN_NAMES))[0]['self.__COLUMN_NAMES[i]] and set a new value and save the table where the foreign key points to. But if part_property[0].catogory is None I have no object type for creating an object of the foreign key table. Is it possible to get the object type dynamically from the PartProperty / PartProperty model? -

django: Handling two values in one field
Intro: I have time series data that need to be stored in with the date_created, the its value. Also, each list of values will have a column where I define some constants.

Why Django's POST doesn't do anything - not even an error?
I'm doing an assignment for Uni from Python/Django. One of the things I have to do is to create a form where a user can create a new "tournament" on the website. Frontend doesn't matter at all. I created a model, added some tournaments from the Admin panel and that works fine. But when I try to create a new tournament from the form, and click the sumbit button, I get redirected to my home page (even though nothing specifies in the HTML or views.py that this should happen), I get no error, no data posted and no info back from the command line. models.py: class Tournament(models.Model): title = models.CharField(max_length=30) creator = models.OneToOneField(User, on_delete=models.CASCADE) players = models.ManyToManyField(User, related_name="players",) created_date = models.DateField(auto_now=True) start_date = models.DateField(auto_now=True) max_players = models.IntegerField( null=True, validators=[MinValueValidator(2), MaxValueValidator(64)]) slug = models.SlugField(unique=True, db_index=True) def __str__(self): return f"{self.title} \n {self.creator} \n {self.max_players}" Forms.py class TournamentForm(forms.ModelForm): class Meta: model = Tournament #exclude = ["slug"] fields = "__all__" views.py class TournamentView(View): def get(self, request): form = TournamentForm() print(form.errors) return render(request, "tournament_app/new_tournament.html", { "form": form }) def post(self, request): form = TournamentForm(request.POST) if form.is_valid(): print(form.errors) form.save() return redirect("/thank-you") print(form.errors) return render(request, "tournament_app/new_tournament.html", { "form": form }) The HTML file {% extends "base.html" %} … -

Django conditional querysets
Alright, So I'm using a general listview showing all orders where the payment hasn't been completed yet. Let's call them outstanding orders, orders which still require some sort of payment. Orders contain one or multiple items and can contain zero or more payments. So I want to compare the total order value, compare this value with the total payment and if these or not equal to zero, show them in the list. Is there someway I can build a new queryset for items which do not meet a certain condition? views.py class OutstandingOrderListView(ListView): model = Order def get_queryset(self): queryset = Order.objects.all()[:5] for record in queryset.iterator(): # Retrieve order_total order_total = record.item_set.aggregate(total=Sum('price'))['total'] # Retrieve payment_total payment_total = record.payment_set.aggregate(total=Sum('amount'))['total'] # Compare both delta = order_total - payment_total if delta != 0: print("These guys owe you money!") # Add record to new queryset? -
Facing a bit weird CORS issues in django template. Some files from same path getting rendered but some are not
We have been using a combination of AWS Cloudfront to serve static files (hosted in S3) for our Django project. Things were running smoothly till yesterday. However now suddenly, we are facing cors issues for a few of our files. Also it looks like the way of calling is giving the issue. But I think that shouldn't be the case. When I look at the inspect, the font when called as , it is getting downloaded However, our original method of importing it under @font-face is what is giving it issues. which goes like: @font-face { font-family: 'HKGroteskPro'; font-weight:300; src: url('{% static 'landikit/fonts/HK Grotesk Pro/HKGroteskPro-Light.otf' %}'); } Have tried invalidating and giving this folder precedence on cloudfront too, but still no luck. Anyone who have faced a similar issue and can how this can be solved? -
how to use same token for reset username and reset passsword with djoser?
I use djoser in my django API just to handle reset_password and reset_username of users. I want to reset both of them in the same view. But I meet a problem because token is only valid for 1 change. I run reset_password, I receive a token and my uid. Then I can run reset_password_confirm or reset_username_confirm with this token, but I can't run the second one (the order doesn't matter). I use a piece of code of djoser to check the validity of my token. And I can see that token is unvalid after 1 change. How to change it as valid for 2 requests ? -

django Queryset filter(a__b__c=d): get hold of b for futher filtering
I am writing a method that computes a complex Django QuerySet. It starts like this qs1 = A.objects.filter(b_set__c_obj__user=user) qs1 will eventually become the result, but before it does, the method goes on with several further steps of filtering and annotation. b_set is an 1:n relationship, but I know that at most one of the c_obj can actually match. I need to reference this c_obj, because I need another attribute email from it for one of the filtering steps (which is against instances of another model D selected based on c_obj's email). user can be either a User model instance or an OuterRef Django ORM expression, because the whole queryset created by the method is subsequently also to be used in a subquery. Therefore, any solution that involves evaluating querysets is not suitable for me. I can only build a single queryset. Hmm? -
Django - ValueError cannot assign - must be a - instance
I believe I understand where my issue comes from I am just not sure how to solve it. The issue is that I am trying to save a review for a product but in the select field of the product the items which are displayed are ones they have purchased. I accomplished this by overriding the init method in my form. My issue is with this exact query it doesn't give me the product, it gives me the string that is queried (due to the str in my model). Therefore when I try to add the review to the product this error is getting thrown. My issue is I do not know how I can get the product exactly because in order to display what I want to display in the select field I have to give it that specific query.
