nested forloop: list items sorted by outer one
I have a nested forloop like this: {% for category in categories %} {% for task in tasks %} {% if task.category == category.id %} // show category name if it was not already printed {% endif %} {% endfor %} {% endfor %} I have a list of categories and some tasks. Each task has a foreignkey to a category. Now I want to list the tasks sorted by categories. So for each category I want to print a title. How can I achieve this? I don't know if it is possible to use simple variables in django template to distinguish if I already printed the category name? Or what is best practice to do this? -
Best opensource ML model for matching clash of clans bases
I have a small database containing images of clash of clans bases. What I want is to upload a clash of clans base to the system and the system should search into the database images and return some similar bases based on the input image. A very simple matching AI sort of thing. I am using Django and an opensource model called "Deep Image Search" from this repo: https://github.com/TechyNilesh/DeepImageSearch.git its code snippet is following: from pathlib import Path from DeepImageSearch import Load_Data, Search_Setup import os image_list = Load_Data().from_folder(['media/images/']) ST = Search_Setup(image_list=image_list, model_name='vgg19', pretrained=True, image_count=100) ST.run_index() metadata = ST.get_image_metadata_file() The model loads in settings so that I dont have to load it on every request. I use the model as follows: class CheckLink(APIView): permission_classes = (AllowAny,) def post(self, request): fs = FileSystemStorage(location=settings.MEDIA_ROOT, base_url=settings.MEDIA_URL) image_file = request.FILES['image'] saved_image = fs.save(image_file.name, image_file) images = settings.ST.get_similar_images(os.getcwd()+fs.url(saved_image), number_of_images=3) files = [] for image in images: image_ = StrategySerializer(Strategy.objects.get(picture__icontains=image)).data["picture"] files.append("localhost:8000/"+image_) # image = StrategySerializer(image).data return Response(files) This returns a link of similar images found in the database folder. The problem is it is not accurate at all. I dont know if I am using it right or not. Following is an image in my database: This … -

Avoid n+1 queries in django admin nested detail inlines
I currently have a model in my admin with a child inline: class ChildInline(admin.StackedInline): # displays fields that load other associations @admin.register(Statistic) class ParentAdmin(admin.ModelAdmin): inlines = ( ChildInline, ) This results in an n+1 problem, that could easily be solved with prefetch_related if I could get it to work! I've tried to use prefetch_related on both the child and the parent get_queryset method (among other things) with no luck in eliminating the n+1 issue. Anyone have any working code for this? -
What can cause JSON serialization error during django bulk create
I am getting a weird error when performing a bulk_create. MyModel is a ForeignKey on Item model. It's code that was working perfectly fine. Just made some changes that clean up the objects to be bulk-created, the data on the item themselves is what has been there before. items are unsaved instances of Item model. I see in the traceback that the item objects are being dumped to JSON at some point. I just don't understand why it's becoming problematic now when it wasn't before.

Django testing of PDFs - single test passes but same test fails when all tests are run
I have a Django app in which I have been using Reportlab to produce various PDFs. These are all functioning correctly. However, tests are failing in an odd manner. in various tests I'm using pypdf2.PDFReader like this: response = self.client.get(pdf_url) reader = PdfReader(BytesIO(response.content)) text = '' for page in reader.pages: text += page.extract_text() self.assertTrue("Apples" in text) I have one test which fails when I run the whole test suite. self.assertTrue("Apples" in text) AssertionError: False is not true The strange thing is, if I run the single test on it's own, or one single TestCase, everything passes. Also, if I run tests in reverse, I get 2 failures instead of 1. I checked the content being sent to Reportlab and it contains the string "Apples". PDFReader finds all the other content, but not "Apples". -

Where is my Django project on an Azure Web App
I've successfully deployed a Django app on Azure. For the time being, it's based on SQLLite, but I plan to migrate to MySQL or PostgreSQL. I connected to the Kudu console to locate my project folder. But I cannot see it. I would need that to access manage.py and launch some makemigrations, migrate and createuser for my database server to come. Is that due to the fact I am using a basic (and free) susbscription? Any other hint? Any help is welcome Richard -
How can I take the password from the card and automatically transfer it to a form on another page?
I have a history of generated passwords. Each password has its own frame with ID. Each password has login, website and date of creation in models ( Django Database). Of course when generating a password all fields except date and password are empty. On each password in the password history there is a "Save" button that would give some password a login and a website where it is used. I want that when I go to the form with saving, the password would be automatically written in the form for the corresponding field. In other words, on the history page I want to take the password id, and insert the required password, the id of which matches in the save field on the form page. history.html: <h2 class="text-center mb-4">Passwords History</h2> {% for password in passwords %} <div class="card text-center mb-4"> <div class="card-header">Password ID {{ password.id }}</div> <div class="card-body"> <h5 class="card-title">{{ password.password }}</h5> <h6 class="card-title">{{ password.login }}</h6> <p class="card-text">{{ password.website }}</p> <a href="{% url 'save_pass' password.id %}" class="btn btn-info" >Save to your Passwords</a> </div> <div class="card-footer text-muted">{{ password.date }}</div> </div> {% endfor %} In history.html every card of Password has its own "save" button.

How to add a confirmation popup dialog when saving an object in Django admin?
I have a model with name and email as fields. I want to show a warning popup to the user if there is already an entry with the same name. The user is allowed to create the entry once they acknowledge the warning. I'm looking to implement two specific features in this Django admin interface: Conditional Confirmation Pop-up: I want to display a confirmation pop-up dialog before saving data, but I want it to appear based on a specific condition. This condition is determined by user input. Confirmation for Data Saving: After clicking the 'Save' button, I want to see a confirmation dialog. Data should only be saved if the user confirms the action. I've attempted to use messages to achieve this, but I couldn't find a way to display a warning or error message before saving the data. -

Need Help Speeding Up Django and DRF with Celery TaskResult Table
I am currently working on an application that utilizes Django, Django Rest Framework (DRF), and Celery, with React in the frontend. I've been encountering a significant performance issue where loading the task results through the DRF API takes more than 10 seconds, as indicated by the debug toolbar. This issue becomes even more pronounced when multiple users attempt to access and display task results concurrently, leading to an API slowdown. In some cases, after sending around 10-15 such requests, my API becomes unresponsive for up to a minute and that causes error 499 in my nginx container making the app unusable for a minute or two. To provide some context, I am using the get_task_result_info function to update my custom SpiderTaskResult model. I've had to introduce additional fields to the default Celery TaskResult model to support the specific requirements of my Celery tasks. Here are the steps I've taken thus far to address the issue: Actions Taken: Implemented pagination in React to display a limited number of items (10 per page) in the APIView. While this approach has improved performance somewhat, it required some refactoring in the React code. Experimented with using Django's JsonResponse instead of a typical DRF APIView, … -
Should Django enumeration types like TextChoices be compared with `is` or `==`?
The Django Enumeration Types documention says that fields like models.TextChoices ... work similar to enum from Python’s standard library, but with some modifications. It's recommended to compare Enumeration members by identity (with is): >>> Color.RED is Color.RED True But the Django docs don't seem to say anything about comparing TextChoices values. Which of these two options is preferred? from django.db import models class FooChoices(models.TextChoices): FOO = "foo" BAR = "bar" class FooModel(models.Model): type = models.CharField(max_length=50, choices=FooChoices.choices) @property def is_foo(self): # Either... return self.type == DatapointDefinitionType.FOO # ... or return self.type is DatapointDefinitionType.FOO -
Why getting the "CSRF token is missing" when is already plugged in template?
I wanted to post a login form through AJAX Post request using JQuery: Even i sent the csrf token along the others however somehow Django fails to validify with the token inside a cookie. $(function(){ $(document).on('submit', 'form', function(event){ event.preventDefault(); $.ajax({ type: 'POST', url: 'login', data: JSON.stringify({ username: $('input[name=username]').val(), password: $('input[name=password]').val(), csrfmiddlewaretoken: $('input[name=csrfmiddlewaretoken]').val() }), success: function(response){ console.log(response); } }); }); Here is the view function that url goes to: def login(request): if request.method == "POST": username = request.POST["username"] password = request.POST["password"] user = auth.authenticate(username=username, password=password) if user: auth.login(request, user) return HttpResponse("Successfully logged in!") else: return HttpResponse("Username or Password is incorrect") else: return render(request, "login.html") 1.I thought that it would be solved if i didn't use {% csrf_token %} and i tried to get token and send to be rendered in the template in view.py: from django.middleware.csrf import get_token csrf_token = get_token(request) return render(request, 'login.html', {'csrf_token':csrf_token} it didn't solve the problem i still got that error. 2.I thought that it might be something related to the csrf cookie value. Everytime i registered a user to the database just the sessionid cookie's value changed and the csrf cookie remained same but i don't know how can i go about that. Any help would … -

Django test parallel fails while clone database

And after that I got error with cloning, and tests that ran on failed copies raised the next error MySQLdb.ProgrammingError: (1146, "Table 'test_dbname_8.django_content_type' doesn't exist") This is very strange because sometimes I have successful test runs. Maybe the reason is MySQL, which does not support parallel execution well? without --parallel flag tests work fine -
ktor - make a post request with different naming of the keys of the JSON in kotlin and django
I want to make a post request with different naming of the JSON keys in Ktor and django. It is not a big deal but I want to follow the convention of naming the vals in Kotlin and django. This is how my user post request body looks in Kotlin/Ktor: @Serializable data class UserPostRequest( val username: String, val email: String, val password: String, val password_check: String ) The problem with this on is the "password_check" val, which is not named by convention Property name 'password_check' should not contain underscores When I try to change it to passwordCheck, make post request, it returns me an error that the passwords do not match. I assumed this is because django expects 'password_check' as a JSON key. -

What is the minimal setup for a Django Custom User Model?
I would like to install, as recommended, a custom user model for a new project early in the process, to avoid complications in migrating further down the line. But since the project is under development and acts as a testbed, I don't yet know which additional fields and methods I will require.
