Django is too slow when processing exception
The view where the exception happens is processing a big dictionary with about ~350K entries. The exception is a KeyError. From what I can see from the CProfile logs, Django is trying to iterate the dictionary to get traceback data. This is simplified code from the view: @login_required def export_plan_data(request): try: form = PortfolioPlanningForm(request.GET, user=request.user) file = get_export_file(user=request.user, form.get_params()) # This is where the exception happens filename = f"Plan {timezone.now().strftime('%Y-%m-%d %H:%M:%S')}.xlsx" response = HttpResponse(file, content_type="application/vnd.openxmlformats-officedocument.spreadsheetml.sheet") response["Content-Disposition"] = f"attachment; filename={filename}" return response except Exception as e: return JsonResponse({"error": "An error occurred while exporting the data"}, status=500) If I surround the entire view in a try/except block and return my custom response when an exception occurs it returns in about 10 seconds, but if I remove the try/except block and let Django handle the exception it takes about 5 minutes. Here's the Cprofile dump: 292357310 function calls (260422005 primitive calls) in 247.585 seconds Ordered by: cumulative time ncalls tottime percall cumtime percall filename:lineno(function) 1 0.000 0.000 247.585 247.585 /usr/local/lib/python3.9/site-packages/django/core/handlers/exception.py:44(inner) 1 0.000 0.000 241.196 241.196 /usr/local/lib/python3.9/site-packages/django/core/handlers/exception.py:54(response_for_exception) 1 0.000 0.000 241.194 241.194 /usr/local/lib/python3.9/site-packages/django/core/handlers/exception.py:140(handle_uncaught_exception) 1 0.000 0.000 241.194 241.194 /usr/local/lib/python3.9/site-packages/django/views/debug.py:50(technical_500_response) 1 0.000 0.000 241.192 241.192 /usr/local/lib/python3.9/site-packages/django/views/debug.py:341(get_traceback_html) 429 0.001 0.000 241.047 0.562 /usr/local/lib/python3.9/site-packages/django/template/defaultfilters.py:916(pprint) 429 0.001 0.000 … -
Why does Django require javascript to be linked in the head instead of the end of the body?
I had to do a few extended templates in django. For simplicity let's call them base.html, blog_base.html, and blog.html. (blog extends blog_base, blog_base extends base). I have a few javascript files in base.html, which worked fine in blog_base.html, but when blog.html was loaded, no GET request was ever sent to retrieve the files. I found that the only location for the tags that worked were in the section of base.html. This is odd to me because not a single other location I put these (even in blog.html) was able to load the static files. Is this a django problem or a javascript? -
Weblate Import initial data via database or rest api
Does anybody have an idea how to import translation units into Weblate? I wanted to add them via the database, but I can't create the id_hash. Using the REST API is too slow for my amount of data. It's for a single import just the initial data. -

django strange behavior with url with slug and /
I am encountering a strange django behavior that I don't see where it could go wrong. I have the start of an app that returns dynamic pages whose url is created through the slug. Everything works well. With any slug I try it works perfectly and the urls find their path without problem. They all go through the same path. But there is ONLY one slug that does not find the path. The peculiarity of the behavior is that in the browser's url it is the only <a href> that adds the / to the url, even though in the html code it does not have the / in the href. I don't understand when the / is added, since all the pages are generated dynamically and go through the same process. This is the page sended to the browser with all links. The url is made dinamically with the slug of the model of each post. <h2><a href="/posts/first-post"> my post first </a></h2> <h2><a href="/posts/fourth-post"> my 4th post </a></h2> <h2><a href="/posts/ready-for-summer"> Ready for Summer Fun! </a></h2> <h2><a href="/posts/third-post"> my 3th post </a></h2> When you click to each links, everything goes fine and the page with the post is sended. the … -

Django allauth facebook login redirects to signup page
I have problem with logging to my app via Facebook. When I'm passing through facebook login form it redirect me to /accounts/social/signup/#= page in my app. My settings: ACCOUNT_USERNAME_REQUIRED = True ACCOUNT_EMAIL_VERIFICATION = "mandatory" SOCIALACCOUNT_EMAIL_VERIFICATION = "none" ACCOUNT_EMAIL_REQUIRED = True ACCOUNT_CONFIRM_EMAIL_ON_GET = True SOCIALACCOUNT_AUTO_SIGNUP = True ACCOUNT_ADAPTER = "apps.users.adapter.MyAccountAdapter" SOCIALACCOUNT_ADAPTER = "apps.users.adapter.MySocialAccountAdapter" ACCOUNT_UNIQUE_EMAIL = False django-allauth version is 0.41.0 (it's old because it's legacy code) Interestingly, on test environment django-allauth does not redirect me (the same facebook client and secret and the same config) to signup page. What may cause the same configuration to work differently in different environments? I've tried with different config but still problem is the same. I don't want to be redirected to signup page. -

How to code efficiently in a django project?
I am begineer in django, i am doing my first project in django. I am using mysql database with my project. Now while fetching data from the database and showing it in different sections of my projects need some logic, so i am using simple "for loops" , "if else statements" to do all this. I am also using boolean flags inside the database to execute different logic. I want to know, is this a correct approach to make a django project, or is there any startergy i should follow while adding new features or making new code ? Kindly help, I just want to know about the technique i should follow, as a begineer this question might be simple but it might be important for many as well.

How do I minify my HTML so that CSS and FontAwesome and Bootstrap names are reduced
I have a Django website that displays a table with data. It uses FontAwesome and Bootstrap for styling - which leads to some lengthy HTML (a standard page is 136k). Eg Some TDs contain an arrow using FA and a style to rotate it eg <i class="fa-solid fa-arrow-down fa-lg fa-rotate-by" style=--fa-rotate-angle:282deg></i> Is there a way to minify or some how reduce the name sizes? I have been reading about webpack and gulp minifiers but I cannot find anything that mentions the use of 3rd party assets like FA and BS and how one might reduce their name sizes. Also these seem somewhat targeted to client-side frameworks rather than server-side which mine is. -

How to reduce the amount of HTML style code
I have a Django website that displays data in a table, most of the data is highlighted with a calculated background color to make it quickly obvious to the user. Is there a way to reduce the amount of HTML I am outputting? Eg: <td style=background-color:#5eff00>19</td> Ideally I'd use CSS - but I would literally be creating a class for every hex color value. Is there a better way? I did consider using the html bgcolor attribute but this is not supported by HTML5. Is this a possibility? -
Django code freezes using Daphne on async database queries
I am running an async django application that is downloading some data. As I want the downloads to run asynchronously, I defined some async methods to run as coroutines. These methods sometimes have Django ORM queries, which I also run asynchronously (async for loop, sync_to_async or .aget(), for example). Since I'd like to display the download progress in clients browser in realtime, I installed django-channels together with daphne to setup websockets. However, If I run my code without daphne, everything works perfect. But as soon as I register daphne as app in settings.py (that runserver is actually running daphne serevr), the code stucks at a async database query.
