JavaScript only works on index.html in a Django web app
I recently started to integrate JavaScript into my Django projects. However, I am facing an issue: Whenever I try to animate an element by clicking on a button it works fine in the index.html but not on other templates that extend the layout.html. I am new to JavaScript so I couldn't trace back the roots of the problem. Here is my code: index.html {% load static %} <!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <meta http-equiv="X-UA-Compatible" content="IE=edge"> <meta name="viewport" content="width=device-width, initial-scale=1.0"> <link rel="stylesheet" type="text/css" href="{% static 'css/main.css' %}"> <script type="text/javascript" src="{% static 'js/script.js' %}"></script> <script type="text/javascript" src="{% static 'js/anime.min.js' %}"></script> <title>Meine Website</title> </head> <body> <div id="ball"></div> <button id="btnwow">Animieren</button> </body> </html> layout.html {% load static %} <!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <meta http-equiv="X-UA-Compatible" content="IE=edge"> <meta name="viewport" content="width=device-width, initial-scale=1.0"> <link rel="stylesheet" type="text/css" href="{% static 'css/main.css' %}"> <script type="text/javascript" src="{% static 'js/script.js' %}"></script> <script type="text/javascript" src="{% static 'js/anime.min.js' %}"></script> <title>Layout</title> </head> <body> {% block body %} {% endblock %} </body> </html> thoughts.html {% extends 'website/layout.html' %} {% load static %} {% block body %} <div id="ball"></div> <button id="btnwow">Animieren</button> {% endblock %} script.js (in the same folder with anime.min.js) function animateStart(){ anime({ targets: '#topbar', translateY: [-500, 0], easing: 'easeInOutCirc', opacity: [.1, 1], … -

How to implement a generalized uniqueness DB constraint (A,B) and (B,A) in Django?
I want to check the database before an object is created with fields one='a' and two='b', and not create (throw an exception) if the database already has rows with fields one='b' and two='a' (reverse order). That is, guarantee that only one of (one, two) and (two, one) exists. It's like a generalized uniqueness constraint. I'm using Django 3.2. I see CheckConstraint supports a boolean Expression, and one type of expression is an aggregate. So I can imagine testing that the number of rows with (one, two) and (two, one) is at most 1. However, that sounds expensive, and I also don't see examples of how to use a Count in the CheckConstraint. Alternatively, I could implement a pre_save signal that issues a query. This seems better, as I'll have the data in hand to form the query. However, I don't see how to prevent the save using the pre_save signal. Does it have a return value I can use? I don't see that in the docs. I'm open to other ideas as well. -
Using django-hitcount in function-based view
I am trying to implement the logic used HitCountDetailView of django-hitcount module. I've successfully implemented it. My problem now is how can I make it count hit because now it counts one hit for each IP. Example. If I hit an object 5 times, it only counts the first one but I want it to count all. What do I need to overwrite? Below is my function def stats(request, watched_object): object = get_object_or_404(My_model, pk=watched_object.pk) context = {} hit_count = get_hitcount_model().objects.get_for_object(object) hits = hit_count.hits hitcontext = context['hitcount'] = {'pk': hit_count.pk} hit_count_response = HitCountMixin.hit_count(request, hit_count) if hit_count_response.hit_counted: hits = hits + 1 hitcontext['hit_counted'] = hit_count_response.hit_counted hitcontext['hit_message'] = hit_count_response.hit_message hitcontext['total_hits'] = hits return context -
Django filtering over multiple pages
I'm still new to Django and web development, sorry if the question is stupid. I currently have a search bar and a drop down list for a category, which then sends the query set to the results template. The result template also has filters to further refine The search, like price range, condition and for sorting. I was wondering what would be the best way to implement these filters without losing the query set from the previous page. views.py class ProductListView(ListView): model = Product template_name = "products/index.html" context_object_name = 'products' paginate_by = 10 class ProductSearch(ListView): model = Product template_name = "products/ad-list-view.html" context_object_name = "products" def get_context_data(self, **kwargs): context = super(ProductSearch, self).get_context_data(**kwargs) Product_list = super().get_queryset() context.update({ 'filter': ProductFilter( self.request.GET, queryset=Product_list) }) return context def get_queryset(self): search_query = '' if self.request.GET.get('search_query') or self.request.GET.get('category'): search_query = self.request.GET.get('search_query') option = self.request.GET.get('category') category = Category.objects.filter(Name__icontains=option) ducts = Product.objects.distinct().filter( Q(Product_name__icontains=search_query), category__in=category,) return ducts return search_query index.py <div class="container"> <div class="row justify-content-center"> <div class="col-lg-12 col-md-12 align-content-center"> <form method="GET" action="{% url 'Product-search' %}"> <div class="form-row"> <div class="form-group col-md-4"> <input type="text" class="form-control my-2 my-lg-1" id="inputtext4" placeholder="What are you looking for" name="search_query" value="{{search_query}}"> </div> <div class="form-group col-md-3"> <select name="featured" value= "{{featured}}" class="w-100 form-control mt-lg-1 mt-md-2"> <option value= null>Category</option> {% for … -
Debugging Django with VS Code inside a Docker container shuts down the container
I'm following this guide for debugging Django inside a Docker container using VS Code. The only difference I've made was changing ports to 8000 and host to 0.0.0.0 because my docker-compose has it like that. I have no idea why the web container shuts down when I run Django with a breakpoint inside a view because I'm don't really know where the problem is coming from. My only guess is from the vscode/launch.json file that is set up by the following: { "version": "0.2.0", "configurations": [ { "name": "Run Django", "type": "python", "request": "attach", "pathMappings": [ { "localRoot": "${workspaceFolder}/app", "remoteRoot": "/usr/src/app" } ], "port": 8000, "host": "0.0.0.0", } ] } Any ideas why this is not working or where the problem is coming from? -
Using django url scheme with Javascript fetch API
I want to use django url scheme when working with fetch API, but it's not understood and i end up with an escaped URL. I followed this tutorial (in french sorry) in which the author achieve it very easily. Demonstrated here Example code : let url = "{% url 'myapp:search_user' %}" const request = new Request(url, {method: 'POST', body: formData}); fetch(request) .then(response => response.json()) .then(result => { console.log(result) }) Which ends up with a console error : POST http://127.0.0.1:8000/myapp/actions/%7B%%20url%20'myapp:search_user'%20%%7D 404 (Not found) Of course my URL is declared in url.py and works well when used in templates. If I replace "url" with relative path it's work well, but that's not django friendly. What I am missing ? -
"We're Sorry, Client not found" FreeIPA, Keycloak setup

Bypassing django-rest-framework APIExceptions
I would like to understand the implications of the following design choice for an application built using DRF. Is it okay if I choose to raise exceptions that are not an instance of APIException in conjunction with a custom_exception_handler that can handle all these exceptions? From what I understand, the handler for a specific request is determined within the rest_framework.views.APIView.dispatch method (source) and the handler gets called within the try...catch.. block in this dispatch method (source). So this way any exceptions that are raised during the execution of the handler are caught within the dispatch method are delegated to the exception handler (default or custom). As we can see here the dispatch method catches not an APIException but any and all Exception. So could I simply raise my own CustomException(s) that are sub-classes of Exception through out my application and simply handle all these exceptions the way I want in the custom_exception_handler? I understand that the ValidationError will be an exception to this, as the serializers and in-built validators all raise ValidationError. If I can override the rest_framework.serializers.Serializer.is_valid in MyCustomSerializer I can catch the rest_Framework.serializers.ValidationError and throw MyOwnCustomValidationError which can be handled by the custom_exception_handler. Something like this: def is_valid(self, … -

Python/Django Query to check if Dates Overlap
I'm trying to set up a validation on an API built with Python/Django. I'm using a serializer and would like to do a query filter against the post data to make sure 2 date fields do not overlap. For example: My Post contains: "valid_start": "2021-09-01", "valid_end": "2021-09-15" I would like to an object.filter to check if there are any records in my database with overlapping dates: I want to throw a validation error if the query detects any of the following "valid_start": "2021-09-01", "valid_end": "2021-09-15" "valid_start": "2021-09-02", "valid_end": "2021-09-15" "valid_start": "2021-09-03", "valid_end": "2021-09-10" "valid_start": "2021-08-28", "valid_end": "2021-09-20" I've tried the __range function, gte/lte functions, none really do what I'm trying to achieve.

Django: Send current logged in user as JSON

How does Django know if object exists
Let's say I have two models, for example: class Product: product_name = models.CharField(max_length=40) class ProductPrice(models.Model): product = models.OneToOneField(Product, on_delete=models.CASCADE) product_price = models.FloatField() Please don't bother why someone might want two different models/tables for such data. That's not the main point here. What's interesting is, when I query a Product I will get a python attr productprice along with the object ONLY IF ProductPrice exist associated with that Product. To make this more clear let's create some dummy data: product1 = Product.objects.create(product_name='first product') product2 = Product.objects.create(product_name='second product') product_price = ProductPrice.objects.create(product=product2, price=10.99) Now try this print(hasattr(product1`, "productprice")) # -> false print(hasattr(product2`, "productprice")) # -> true How does django know that a ProductPrice exist in database?

What is a better approach to cache data in django app when running on gunicorn
I have a django application that is running on gunicorn app server. Gunicorn running N wokers. We know that each worker is a separate python proccess. In one of my applications services i have a query to a database that takes long time (10-20 sec). Ok i decided to cache the result, so just simply add django.core.cache and call cache.get(key) if result is not None app returned data from cache if not it called service and stored data in cache using cache.set(key, data, time). But if we have a N workers and first query was addressed to worker 0 app stored result of long running service in cache (process memory) of worker 0 but when simillar (request contains paging option, but i store whole RawDataSet in memory, so every page returns fast) request is addressed to worker 1 cache as expected would't work because this is a different process. So obviously i have to use some cache that could be used by all workers. What approach (i.e. use in memory database or something different) is better to use to solve this issue? -

I am using django-pymemcache which extends the pymemcache library and is a wrapper around memcached. settings.py CACHES = { 'default': { 'BACKEND': 'django.core.cache.backends.memcached.PyMemcacheCache', 'LOCATION': '53.171.42.209', 'OPTIONS': {} } } I've tested it while running the memcached service locally and specifying a location of (127.0.0.1:11211) and it works as expected. I know that the memcached service is listening on port 11211 of the azure vm. I've opened up inbound rules on azure to allow connection. But it refuses my connection, I assume because I haven't specified any sort of credentials to connect to it. I can't figure out how to do that piece, and if it's the only thing that I'm missing.
