Django query taking a long time to run
I have created a query in get_context of a Class Based View from which I generate a dict I send into a Django template to display alongside a formset. The number of records returned is about 40 and it takes about 5 seconds to run - which will translate to 30 or 40 seconds with a full set of data. Looking at Django Debug Toolbar SQL queries, it is continuing to run 40 additional queries despite adding what look like the correct select_related and prefetch_related for the reverse related table to my queryset. My models (simplified for this example): class Item(models.Model): name = models.CharField(max_length=20, primary_key=True) description = models.CharField(max_length=35, blank=True, null=True) def __str__(self): return f"{self.name}" class ItemLocSite(models.Model): name = models.CharField(max_length=10, primary_key=True) models.CharField(max_length=10) class Meta: def __str__(self): return f"{self.name}" class ItemLoc(AbstractAddArchive): item = models.ForeignKey(Item, on_delete=models.PROTECT) iloc = models.ForeignKey(ItemLocSite, on_delete=models.SET_NULL, null=True, blank=True, related_name='iloc') nloc = models.ForeignKey(ItemLocSite, on_delete=models.SET_NULL, null=True, blank=True, related_name='nloc') cp_date = models.DateField(null=True, blank=True) posted_by = models.ForeignKey(User, on_delete=models.PROTECT, max_length=10, null=True, blank=True) class Meta: def __str__(self): return f"{self.item}" class ItemInfo(AbstractAddArchive): item = models.ForeignKey(Item, on_delete=models.PROTECT) log_entry = models.ForeignKey(Log, on_delete=models.PROTECT, null=True, blank=True) c = models.CharField(max_length=2, blank=True, null=True) crec_log_entry = models.ForeignKey(InvLog, on_delete=models.PROTECT, related_name='crec_log_entry', blank=True, null=True) csts = models.ForeignKey(ItemSts, on_delete=models.PROTECT, null=True, blank=True) cfill = models.IntegerField(blank=True, null=True) comment1 = … -
How can I use python magic on Heroku as well as local windows machine?
My django project uses python-magic. In order to get magic working on my local windows machine, I've had to install python-magic-bin, otherwise I faced the error "ImportError: failed to find libmagic. Check your installation". But when I push this dependency to my Heroku (linux) server, my build fails with the error "Could not find a version that satisfies the requirement python-magic-bin==0.4.14. No matching distribution found for python-magic-bin==0.4.14." I'm importing magic as "import magic". I've seen another answer here on an old post which said the issue came from using "from magic import magic", but that's not the case here. What do I need to do to get python-magic working on both setups? I dont want to have to remember to keep python-magic-bin out of the requirements.txt for the remote server. -
Accessing current user location and showing all the users near it
I am building a BlogApp and I am stuck on a Problem. What i am trying to do :- I am trying to access user's current location and showing all the user that are nearby of the User. The Problem :- I don't know how to access the current location of user and show all the users near it.

Django prevent direct url access
lets say I have a "Success Page" view. .urls urlpatterns = [ path('success/', views.inquiry_success, name='inquiry-success') ] .views def success(request) return render(request, 'success_page.html', {}) I can access this view directly by typing mysite.com/success in the browser even without going through the subsequent process that should result in showing that page.

How to start Count from 0 in django annotation?
I have the following code to count tickets related to each event. class EventManager(models.Manager.from_queryset(EventQuerySet)): def get_queryset(self): attendees_count = Sum(Case( When(~Q(ticket__ticket_number=""), then=1), output_field=models.IntegerField() )) return super(EventManager, self).get_queryset().annotate(attendees_count=attendees_count) the When(~Q(ticket__ticket_number=""), then=1) part exculdes all tickets which do not have a ticket number. It works well for events where is more than one valid ticket (if 4, shows 4). However, when there is no ticket associated, it returns 1. Behaviour is like so; 0 related tickets - returns 1, 1 related ticket - 1, 2 related tickets - 2 etc. How to start counting from 0? so 0 related tickets - returns 0? -
Is it possible to allow a user to create a group and then add users to a group without the admin aspect?
Currently testing what i can do with django, I get that I'm able to query set users but Is it possible to allow users to add people to groups that they've created. Any group-related documentation I've found for django has been admin based. Does this require creating a new model for group? -
Django - How to send location info from template (that uses Maps Javascript api) to database
I have a simple django project that currently only displays a map with the users location that updates every 30 seconds. The location is found using googles Maps Javascript api within the template. What I need to do is send the location info to the database from the html template every time the location updates. Any answers I've seen to similar stuff use forms that require some sort of user interaction. What I need is for the info to be automatically sent to the database every time the location is updated without any user interaction. Basically, is there a way to continuously send a variable created in a templates javascript back to the database without user interaction? (The django project only has one page that only gets and shows the user location on a map so it is very basic at the moment.) -
Django - can we make a model inherit itself?

Django Update Session Variable with AJAX
I am making a restaurant application and I am making takeaway functionality.I currently have the basket quantity in a session variable that updates whenever the user adds an item to the basket. When they add to the basket, the whole page is refreshed. This is done by passing the FoodItem ID through the URL's via GET requests. I wish to implement AJAX in this scenario so that the session variable updates on the template and the whole page does not refresh. Current response when session variable updates: return HttpResponseRedirect("/takeaway_menu/") Url for updating the session variable: path('basket/update/<int:food_id>/', update_basket_view, name='update_basket'), Each food item form in template: <form method="get" action="{% url 'update_basket' food.id %}"> <label for="quantity">Quantity</label> <button id="increment" name="increment" type="button" onclick="decreaseQuantity(this)">-</button> <input class="quantity" id="quantity" name="quantity" type="number" value="1"> <button id="increment" name="increment" type="button" onclick="increaseQuantity(this)">+</button> <input type="submit" value="Add to Cart"> </form> how I am displaying session variable in template <a id="basket" href="{% url 'basket' %}">Basket: {{ request.session.item_quantities }} items <i class="fa fa-shopping-basket" aria-hidden="true"></i></a> Is it possible to do? I can't figure out a way to do this. -
foreign key linked field "Author" of a table "skills" is always empty in the database
I am building a web application where students can see the job posts posted by tutors. tutors can login into the site and post jobs.

Pending request to 3rd party API freezes all other django requests/endpoints
I use Django 2.2.6, python 3.7 and requests 2.25.1. Since I have started consuming a 3rd party APIs, I have noticed that if the request to this 3rd party API takes too long to respond, in the meanwhile all my Django endpoints are freezed, waiting for it. For instance, lets say I have these 2 endpoints in my Django: ENDPOINT A - GET a certain product (e.g. /product/{id}/): def get_product(request, id): product = Product.objects.get(pk=id) return JsonResponse(product) ENDPOINT B - POST a payment to a 3rd party API (e.g. /product/{id}/payment/): import requests def pay_for_product(request): payload = json.loads(request.body) response = session.post(url='https://api.paymentprocessorXPTO.com/pay/',data=payload) content = json.loads(response.content) return JsonResponse(content) For code simplicity reasons, I would like the ENDPOINT B to wait for the 3rd party API response syncronously and send it back to the user, as the code above. Thus I have not tried or wished for using a queue (e.g. celery / django-rq). The problem is: with the current code, if the session.post(...) in ENDPOINT B takes for example 20 seconds, all my Django endpoints are unavailable for 20 seconds. For instance, while a payment is being made by a client, all other client's GET product requests (ENDPOINT A) will take 20 seconds instead … -
How to instantiate a class just after starting Django server and access its members later in views.py
