Django's makemessages generates corrupt po file
My code contains this line (beside lots more i18n texts): filter_text = _('Filter') I generate the "de" locale po file (see missing prefix "#:"): django-admin makemessages --locale de -i venv The resulting po file ist corrupt: #: .\oam\views\article\article_list.py:138 #: .\oam\views\fillup\fillup_list.py:109 #: .\oam\views\setting\setting_list.py:49 .\oam\views\stock\stock_list.py:75 #: .\oam\views\tom_article\tom_article_list.py:53 #: .\oam\views\transaction\transaction_list.py:90 msgid "Filter" msgstr "Filter" Running makemessages again of course leads into errors: CommandError: errors happened while running msgmerge c:\work\pro\ceratizit\apollo\oam\locale\de\LC_MESSAGES\django.po:1915:3: syntax error c:\work\pro\ceratizit\apollo\oam\locale\de\LC_MESSAGES\django.po:1915: keyword "oam" unknown c:\work\pro\ceratizit\apollo\oam\locale\de\LC_MESSAGES\django.po:1915: keyword "views" unknown c:\work\pro\ceratizit\apollo\oam\locale\de\LC_MESSAGES\django.po:1915: keyword "stock" unknown c:\work\pro\ceratizit\apollo\oam\locale\de\LC_MESSAGES\django.po:1915: keyword "stock_list" unknown c:\work\pro\ceratizit\apollo\oam\locale\de\LC_MESSAGES\django.po:1915: keyword "py" unknown msgmerge: found 6 fatal errors When removing the i18n at this line the makemessages works well: filter_text = 'Filter' I'm totally lost. Any hints? Thanks! -

How to add fields to serializer

How does PostgreSQL handle get() in Django for exact file path matches and its performance?
I’m using Django with a PostgreSQL database, and I have a model that stores file paths (specifically S3 file paths) in a CharField, like this: class File(models.Model): file_path = models.CharField(max_length=255) I often retrieve a single file record using Django’s get() method with an exact S3 file path match: file = File.objects.get(file_path='/bucket/path/to/file.txt') This translates to the following SQL query: SELECT * FROM my_table WHERE file_path = '/bucket/path/to/file.txt' LIMIT 1; I want to understand what happens under the hood when PostgreSQL processes this query. Specifically: 1. How does PostgreSQL handle the comparison of strings when using the = operator on a CharField with an S3 file path? 2. Does PostgreSQL behave differently if there’s an index on the file_path column, and how does it decide between using an index or performing a sequential scan? 3. Is it beneficial to create an index on the file_path field for better performance, -
Creating Forms that Redirects to Different URL When Successful
So I have created two folders (Aside from my main project folder) One of my folders is the main app and the second folder is a users folder. Error Message: Page not found (404) Request Method: POST Request URL: http://127.0.0.1:8000/users/register Using the URLconf defined in cooknook.urls, Django tried these URL patterns, in this order: admin/ users/ register/ [name='cooknook-register'] [name='cooknook-home'] about/ [name='cooknook-about'] account/ [name='cooknook-account'] The current path, users/register, didn’t match any of these. ^^ Error Thrown So In my views.py inside of my users folder I am telling it after success: ` def register(response): if response.method == "POST": form = UserCreationForm() if form.is_valid(): form.save()` return redirect('cooknook-home') Basically, I did already try to outsource the problem and tried to implement 'reverse' function in this which did not seem to work at all. The problem is that it seems it is trying to find the urls/html(temps) inside of my cooknookapp folder which is my main app folder. I'm needing it to redirect to home.html (located inside of my main app folder) How can I get Django to look outside of the Users/ Dir for this? I was expecting for it to send me to the home page which is located in the cooknookapp … -
How to expose the drf_spectacular autogenerated documentation of a class-based view that has no direct reference in urls.py?
I have a Django app that based on specific condition, executes one or another class-based view. def compatibility_whatever_view(request: Request, *args, **kwargs) -> Response: if is_legacy: return LegacyWhateverView.as_view()(request, *args, **kwargs) else: return WhateverView.as_view()(request, *args, **kwargs) I have my WhateverView and LegacyWhateverView with fully compatible API. urlpatterns = [ path( "whatever/<uuid:whatever_id>/", compatibility_whatever_view, name="whatever_list_whatevers", ), ] I want to expose the documentation of WhateverView using drf_spectacular. Unfortunately I am failing to do so, as it seems the swagger.yml file is generated only if the class-based view is directly exposed in the urlpatterns, otherwise it does not know how to build the URL endpoint. This totally makes sense, but I would like to be able to somehow expose the automatically generated of WhateverView to the public. I have tried a bit of magic using: @drf_spectacular.utils.extend_schema(operation_id="whatever_list_whatevers") @rest_framework.decorators.api_view() def compatibility_whatever_view(request, *args, **kwargs): ... but the generated documentation was lacking the details that are otherwise present when I directly reference the class-based view. -
django CMS vs Django
We're planning to build a application tracking system with multiple role and permission. My question is : Which is the best platform django CMS or Django ? I am in the impression that Django CMS comes with all the role / Groups / Permission stuff as default, but in Django I see we have groups I don't see permission concept. Share your expert advices. -
How to mocking a function that returns some value
For example, there is a view that processes a user registration request. The view accepts a phone number and sends an SMS with a code to it. The code is generated by an additional function. Here's how to mocking this function to send the code I need? This is my view def post(self, request): serializer = ReviewerSignUpSerializer(data=request.data) serializer.is_valid(raise_exception=True) phone = serializer.validated_data.get("phone") confirmation_code = get_confirmation_code() cache.set( key=str(phone), value=confirmation_code, timeout=settings.CONFIRMATION_CODE_LIFETIME ) send_sms_task.apply_async([confirmation_code, str(phone)]) This is a function that generates a confirmation code def get_confirmation_code() -> str: seq = list(map(lambda x: str(x), range(10))) shuffle(seq) code = choices(seq, k=settings.INVITE_CODE_LENGTH) return "".join(code) Test function def test_saving_confirmation_code_in_cache(self, client, cache): phone = "+79389999999" generated_code = "9999" with patch("api.v1.authentication.utils.get_confirmation_code", return_value=generated_code): client.post(reverse('api:v1:signup'), data={'phone': phone}) confirmation_code = cache.get(str(phone)) assert confirmation_code is not None assert confirmation_code == generated_code -
Wagtail django.db.utils.OperationalError: (1463, "Non-grouping field 'numchild' is used in HAVING clause")
I'm working on a Django project and I've encountered an issue that I'm unable to resolve. When I try to run my application, I get the following error: django.db.utils.OperationalError: (1463, "Non-grouping field 'numchild' is used in HAVING clause") I'm not sure what's causing this error. I'm not explicitly using a HAVING clause in my queries, and 'numchild' is a field that's managed by Django's** Wagtail** module, not something I've added myself. I'm using the following packages: wagtail>=5.0 mysqlclient==2.2.4 Every things working fine locally using sqlite. I tried to downgrade my mysqlclient version from 2.2.4 to 2. Without sucess. I would like to have the result as sqlite. -
Redis Lock with Django unexpected behaviour

Oauth2 doesn't redirect to my flutter application after successful login
I am trying to implement oauth2 with flutter_appauth package. After successful login the web page should redirect to my mobile application. At this moment, it just stays in web (redirecting to web home page). I'm currently getting this error Redirect to scheme 'com.app.app` is not permitted.

Also, I've tried implementing oauth2 with discoveryUrl and it just crashes the app immediately after login() function is called. Last thing I want to mention is I have already checked redirection uri in admin panel and it's correct. Oauth2 was implemented with Django oauth2 toolkit. -

Closing Socket Reverts Database Data to Earlier State
I'm building a Django SPA, which uses HTTPS requests as well as Django Channels (Socket Communication) for real time updates. When a user logs in, the socket creates an instance(?) for that user, of which data matches the user data in the database. If you change the user data in the database (for example increment wins or change username), this data is not automatically carried over to the socket session, so I will have 2 different states representing the same user. When I then interrupt the socket instance, the database reverts back to the state it was in before the changes. I won't post code, I'm just curious about the description of this anomaly Do I have to refresh manually the user's state in the socket after each database change related to the user? Or is there some way around it? **What I've tried ** When I'm saving the new data to the websocket and also update it's in-memory data e.g: self.scope["user"].username = new_username self.user.username = username That seems to work. However I'm curious if that is necessary for every user related update, or if there is a shorcut to this problem. -

def EmailLoginVerify(request): if request.method == 'POST': if 'token' in request.POST: try: submitted_token = int(request.POST['token']) except ValueError: return HttpResponse('Invalid token format', status=400) if submitted_token == request.session.get('login_token'): email = request.session.get('email') try: target = MyUser.objects.get(email=email) print('user is', target.username, 'and password is', target.password) #export: #>>>>>>>user is maziar and password is pbkdf2_sha256$720000$CY5sjiqAL1yScKzGhzYBp9$2tUx8ScBbbuZlj+u0YfMxwTIRfz5Vfmv+58piWCAjKM= except MyUser.DoesNotExist: return HttpResponse('User Not Found', status=404) user = authenticate(request, username=target.username, password=target.password) print(user) #export: #>>>>> None if user is not None: login(request, user) return HttpResponse('good') else: return HttpResponse('Authentication failed', status=401) else: return HttpResponse('Invalid token', status=403) else: return HttpResponse('Token not provided', status=400) else: return render(request, 'login_verify.html') in the end it return 'Authrntication Failed' this code get an email from the user if a user with that email exists it send a code to the email and if user enter the correct code it should authenticate the user and log it in but it return 'Authentication Failed' enter image description here -
django.db.utils.NotSupportedError: (1235, "This version of MySQL doesn't yet support 'LIMIT & IN/ALL/ANY/SOME subquery'") in Django
I am building a Django application and trying to implement pagination on a large dataset for a report. When querying the database, I encounter the error: django.db.utils.NotSupportedError: (1235, "This version of MySQL doesn't yet support 'LIMIT & IN/ALL/ANY/SOME subquery'"). I'm using MySQL as the database backend. order_queryset = ProformaHeader.objects.filter(process_this_order=True, status=ACTIVE) page_obj = pagination(request, order_queryset.order_, per_page=10) order_queryset = page_obj.object_list podetails = PODetail.objects.filter(proforma__in=order_queryset, po_header__is_vconfirmed=True, status=ACTIVE).select_related('proforma_detail') podetail_map = {p.proforma_detail_id: p for p in podetails} # I encounter the error this line Error occurs on this line: podetail_map = {p.proforma_detail_id: p for p in podetails} # I encounter the error this line The error is raised when attempting to create a dictionary mapping proforma_detail_id to the corresponding podetail object. It seems to be related to the combination of LIMIT and IN in the query generated by Django when retrieving the podetails. Expected Outcome: I expected this line to build a dictionary mapping proforma_detail_id to podetail without triggering an error, allowing me to reference the podetail object for each proforma_detail in the subsequent processing loop. -

How to Enhance Fingerprint Images Without Blurring Ridges? i am using django
How to Enhance Fingerprint Images Without Blurring Ridges? i am using django. I'm currently working on a fingerprint enhancement project using OpenCV, and while my code is producing results, the ridges in the fingerprint images are coming out blurred. here is my code import cv2 import numpy as np import math import fingerprint_enhancer # Ensure this module is available from django.shortcuts import render from django.core.files.base import ContentFile from .forms import HandFingerForm from .models import ThumbImage import base64 MAX_IMAGES = 10 def remove_green(img): empty_img = np.zeros_like(img) RED, GREEN, BLUE = (2, 1, 0) reds = img[:, :, RED] greens = img[:, :, GREEN] blues = img[:, :, BLUE] # Create a mask for the areas to keep tmpMask = (greens < 35) | (reds > greens) | (blues > greens) img[tmpMask == 0] = (0, 0, 0) # Remove background from original picture empty_img[tmpMask] = (255, 255, 255) # Mask with finger in white return img, empty_img def detect_nail(gray_mask_finger): # Find contours in the mask image contours, _ = cv2.findContours(gray_mask_finger, cv2.RETR_EXTERNAL, cv2.CHAIN_APPROX_SIMPLE) for contour in contours: # Only consider large enough contours as nails if cv2.contourArea(contour) > 100: # Adjust this threshold as needed x, y, w, h = cv2.boundingRect(contour) # …
