Django - The current url didn’t match any of the these
I have Django 4.0.4 I tried the following url : http://127.0.0.1:8000/cp2/sbwsec/1076/o2m/section/wseclmts/47/p/element/sbwblmnt/1077/ but it gives me error Page not found (404) The current path, cp2/sbwsec/1076/o2m/section/wseclmts/47/p/element/sbwblmnt/1077/, didn’t match any of these. Using the URLconf defined in myproject.urls, Django tried these URL patterns, in this order: I have 1370 patterns - where the correct pattern is on the line 268 as you can see from the debug exception page cp2/ (?P<parent_element_name>\w+)/(?P<parent_id>\d+)/p/(?P<parent_field>\w+)/sbwblmnt/(?P<item_id>\d+)/$ [name='sbwblmnt_epec'] Thank you for the help -

Uncaught TypeError & memory leak error in materia-table & django
I am working a project with reactjs & material-table for the frontend and Django for the backend. Currently, I am performing CRUD operations using axios on my material-table. However, I have encountered a difficulty when doing the delete request. The table looks like this: enter image description here Everything went well when I delete the 2nd & 3rd row: enter image description here But when I delete the "last row", a bunch of error pops up in console log: DataWorker.js:68 Uncaught TypeError: Cannot read properties of undefined (reading 'id') react-dom.development.js:11102 Uncaught TypeError: Cannot read properties of undefined (reading 'id') react-dom.development.js:88 Warning: Can't perform a React state update on an unmounted component.

Where are captcha values usually stored?
Long story short, I made a captcha that can generate from 26letters + digits using pillow that looks cool, Now I need a way to verify that captcha value without the using of database A practical and easiest way of doing this is with sessions, It does not require read or write to the DB, But since cookies are stored on the frontend, I don't think this is a very secure way of storing the value of the captcha, I want the attacker to actually decode captcha using machine learning and not session value which I assume would be easier for the attacker to do. Is there a way to hot verify them? Even with the use of APIs it changes nothing, In this case APIs would be just like sessions and the only difference would be sending value to another function vs sending value to another url. Are there any other alternatives to where these "single use only values" are stored? Or Is there truly a way to hot verify I haven't thought of? -

How to create one to many generic relation between objects in Django

Wagtail Tagging: How to keep choosen tag order?
I have a Page Model with Tags in it. class ProjectPage(AbstractContentPage): tags = ClusterTaggableManager(through=PageTag, blank=True) content_panels = AppPage.content_panels + [ FieldPanel('tags'), ... and in the template {% if page.tags.count %} <div class="width2"> {% for tag in page.tags.all %} {# Loop through all the existing tags #} &#9654; <a href="{{ self.get_parent.url }}?tag={{ tag.slug }}">{{ tag }}</a><br /> {% endfor %} </div> {% endif %} If The Editor adds 4 Tags to the Tags Field Panel these Tags should appear in same order in the template. That might work if all tags are newly created in the database but Unfortunately it seems that in the many2many table they get stored always in the order the tags where first created and not in the order they where written in the FieldPanel. -

Getting indentation issue in Django while trying to pass context [duplicate]
I'm working on a project for a job interview and this is my first experience with django - I'm trying to upload an image to a dropzone and display it on a separate page. I've made the dropzone and the image upload creates a model, but when trying to pass the model into the render of the other page, I get an indentation issue.

The best setup for Gunicorn + Django or why workers and threads at the same time degrade performance?
On my backend I use Django + Gunicorn. I use Nginx too but that does not matter for this question. Db is Postgres. I want to improve performance of my application (i have some api points with heavy i/o operations that degrade the whole backend), so i decided to survey how gunicorn can help me with that. I have read these SOF answers, and these, and this very nice article and many more but in reality i'm getting rather strange results. I created this point to experiment with Gunicorn config (very simple one): As you can see i have created some i/o operation inside my view. I want to optimize the amount of RPS and to measure that i'm going to use WRK with basic config 2 threads with 10 connections each. Lets start gunicorn with that config (basic simplest sync without any workers): Then i'm getting these results: Ok, that correlates with reality because this api point usually response in 50-100ms. Look: Now lets increase amount of workers to 8: I'm getting: Oops: i supposed that i'll get x8 performance and 160 RPS, because as i thought, new worker works in separate parallel process. 1. So the first question … -
