Django: converting view function to class-based view. Error during login to Admin panel: matching query does not exist
I'm learning how to convert old view.py functions to class-based views. I started with a simple function that displayed a page with my essays, plus, I had a newsletter form and a draft of a comment form (but not attached to DB). I decided to not develop this comment form further in a simple function, but to rebuild all of it to class-based view to learn a better and cleaner approach. I've encountered a problem that I have no idea how to solve. Error: matching query does not exist. And Exception Value: EssayCls matching query does not exist. Most likely I break the logic that connects my model to my DB. I'm looking for suggestions on how to solve issues in my code and suggestions about topics I should learn more about to make this kind of development less cumbersome. Before I rebuild my view, things were working fine and looked like this: views.py: from django_user_agents.utils import get_user_agent from .models import EssayCls, SendMeMessage from .forms import CommentForm def my_essays(request, home_view_author_slug): user_agent = get_user_agent(request) try: selected_essay = EssayCls.objects.get(slug=home_view_author_slug) if request.method == 'GET': user_feeDBack = UserFeeDBack() else: """ The incoming request from Django will have a POST property which contains any submitted … -

Django keyword error but print kwargs shows the key

I can´t publish MQTT messages after a few days

Django query __startswith is not case sensitive
I have been testing user searching with sorted results and I found this strange behavior >>> User.objects.filter(username__istartswith="AbC") <QuerySet [<User: AbC>, <User: AbCuuu>, <User: abc>, <User: abcuuu>]> >>> User.objects.filter(username__startswith="AbC") <QuerySet [<User: AbC>, <User: AbCuuu>, <User: abc>, <User: abcuuu>]> Shouldn't __startswith only have 2 of those results?

How to aggregate over Django Jsonfield values?
I have a JsonField (col1) in a Model (model1) which contains values like below: {"key_1":"val_1", "key_2":"{\"sub_key1\":sub_val1, \"sub_key2\":sub_val2}"} I would like to aggregate sub_key1 and sub_key2.

Handling user images in a web app - format, rotate?
everyone, in my web app (Python - Django) users should be able to upload pictures in the future, which will then be displayed in their own profile (like a Facebook picture post). Accordingly, there will be a file input in which the user can select his image. The image must then be displayed directly, as the user may want to upload several images. Since I'm not familiar with image editing, I'm asking myself a few questions. Currently I send the image to my server via Ajax, compress it and scale it to 400x400 px. if the picture doesn't fit the format, i crop it accordingly, certainly not the prettiest option, because if it doesn't fit, i crop from the middle. Then I save the image, and return the URL and render it. Everything works as desired, I'm just not sure if it's really good. For example, how do I deal with images in landscape format? How do I let the user rotate the picture? For this I would have to save it unchanged, render it and then ask the user? How can I open the "Open camera" function for smartphones? Is this possible in a "normal" mobile website version (or … -

How to create model's tables in MySQL?
I'm trying to replicate a PHP/Symfony project in Python/Django as a python learning exercise. Platform = Windows 10. The expected result is that a migrate command will add tables related to all of the entries in settings.py INSTALLED_APPS{...}. Instead, the migrate command adds all Django tables but none of the tables of models.py. What, then, must be done to allow migrate to add the 5 MySQL tables?

How to represent SVG polygon in HTML using deffinition coming from POSTGIS ST_AsSVG function

It also happens that after I restarted apache the next page loaded. Doing this I was even able to login to the admin UI in 2 steps, so the database is obviously accessible. Meanwhile increased the log level to trace1 of the Apache server and now can see that after 5 minutes the process gets killed and … -

Django - models with relations to possibly nonexisting users
I am working on an enterprise LMS powered by Django REST framework. Authentication is done via Google OAuth 2.0 using the package drf-social-oauth2, and the target organizations for my software are schools and universities. Some models have foreign keys to the user model; however, due to the nature of my application, oftentimes a user may want to reference a user that isn’t present in the database yet. This happens because users are created in the database upon their first login in the application via OAuth, yet the person who wants to create a specific model instance referencing another user may want to do so before they’ve logged in for the first time: for example, a teacher may want to pre-enroll a list of students into their new course, but those users might not have logged in for the first time yet, and therefore might not exist in the database. I’ll give a concrete example with a model in my application: class UserCoursePrivilege(models.Model): """ Represents the administrative permissions a user has over a course. See logic.privileges.py for the available permissions. """ user = models.ForeignKey( User, on_delete=models.CASCADE, related_name="privileged_courses", ) course = models.ForeignKey( Course, on_delete=models.CASCADE, related_name="privileged_users", ) allow_privileges = models.JSONField(default=list, blank=True) deny_privileges = … -
How to force link opening oustide of embedded browser / webview?
I setup a simple authentication system using python-social-auth-django. Everything is working fine on my computer and my mobile phone, but when I try to open login link from Messenger app with another phone (Huawei brand), the link opens inside Messenger's embedded browser and I get belows (same for Facebook and Google oauth). Searching around it has something to do with new policy disabling authentication from embedded browser such as Messenger embedded browser. What should I do either to force my login link to open outside of Messenger embedded browser or allow login with Facebook/Google oauth from WebViews browser ? You can't sign in from this screen because this app doesn't comply with Google's secure browsers policy. If this app has a website, you can open a web browser and try signing in from there. From my browser and own phone I open home link (from messenger app). This opens a browser window and login works fine. From another phone, when I click the messenger link, it opens in embedded browser. -
Next13 fetch to localhost:8000 does not work
Somehow the fetch from next13 doesnt work with Django on localhost:8001. I get the following error: TypeError: fetch failed at Object.processResponse (node:internal/deps/undici/undici:7188:34) at node:internal/deps/undici/undici:7516:42 at node:internal/process/task_queues:140:7 at AsyncResource.runInAsyncScope (node:async_hooks:202:9) at AsyncResource.runMicrotask (node:internal/process/task_queues:137:8) at process.processTicksAndRejections (node:internal/process/task_queues:95:5) { cause: Error: [object Object] at makeNetworkError (node:internal/deps/undici/undici:6317:51) at httpNetworkFetch (node:internal/deps/undici/undici:7810:16) at process.processTicksAndRejections (node:internal/process/task_queues:95:5) at async httpNetworkOrCacheFetch (node:internal/deps/undici/undici:7703:33) at async httpFetch (node:internal/deps/undici/undici:7557:37) at async schemeFetch (node:internal/deps/undici/undici:7489:18) at async node:internal/deps/undici/undici:7342:20 at async mainFetch (node:internal/deps/undici/undici:7338:20) { [cause]: undefined } } TypeError: fetch failed at Object.processResponse (node:internal/deps/undici/undici:7188:34) at node:internal/deps/undici/undici:7516:42 at node:internal/process/task_queues:140:7 at AsyncResource.runInAsyncScope (node:async_hooks:202:9) at AsyncResource.runMicrotask (node:internal/process/task_queues:137:8) at process.processTicksAndRejections (node:internal/process/task_queues:95:5) { digest: '1117663215' with this code: import './globals.css' export default async function RootLayout({ children, }: { children: React.ReactNode }) { // const data = await fetch(`https://dummyjson.com/products/1`, { cache: 'force-cache' }); const data = await fetch(`http://localhost:8001/board/`, { method: 'GET', headers: { 'Accept': 'application/json', "Content-Type": "application/json" }, redirect: 'follow', cache: 'force-cache' }); console.log(data) return ( <html lang="en"> <head /> <body> <h1></h1> <div>{children}</div> </body> </html> ) } Fetching from any other public api works. CORS is enabled and CORS_ORIGIN_ALLOW_ALL = True is set in the Django settings.py Any idea how I can fix this? Thanks -
