Django cors headers not working with POST requests
My stack is: axios for the javascript client, apache2 reverse proxy, gunicorn, django. I have setup the django-cors-headers plugin. I am able to perform GET requests to the django application. However, when I try to perform a POST query, I have a CORS error Cross-Origin Request Blocked: The Same Origin Policy disallows reading the remote resource at https://[...]/move_item. (Reason: CORS header ‘Access-Control-Allow-Origin’ missing). Status code: 200 Cross-Origin Request Blocked: The Same Origin Policy disallows reading the remote resource at https://[...]/move_item. (Reason: CORS request did not succeed). Status code: (null) How is it possible that changing the http method breaks? I have not set a value to the CORS_ALLOW_METHODS from django-cors-headers. Even if I explicitly do (CORS_ALLOW_METHODS = ("DELETE", "GET", "OPTIONS", "PATCH", "POST", "PUT",)), the error persists. My apache config is straightforward. <VirtualHost *:443> ServerName [...] ProxyPass /.well-known !

Why is my Docx converter returning 'None'
I am new to web development and trying to create a language translation app in Django that translates uploaded documents. It relies on a series of interconversions between pdf and docx. When my code ouputs the translated document it cannot be opened. When I inspect the file type I saw it identified as XML and docx and it could be opened and read by MS Word when I changed the extension to docx(But it couldn't be read by any PDF readers). When I used my code python to analyze the file by printing the type and the contents of it I got NoneType and None. A working PDF of the file is found in mysite/mysite folder but the one output by my reConverter function that is sent to the browser is the problem file. I tried manually converting it using: wordObj = win32com.client.Dispatch('Word.Application') docObj = wordObj.Documents.Open(wordFilename) docObj.SaveAs(pdfFilename, FileFormat=wdFormatPDF) docObj.Close() wordObj.Quit() but got a CoInitialization error. My original So I've completely narrowed it down to the reConverter function returning a NoneType. Here is my code: from django.shortcuts import render from django.http import HttpResponse from django.http import JsonResponse from django.views.decorators.csrf import csrf_protect from .models import TranslatedDocument from .forms import UploadFileForm from django.core.files.storage … -
User Based Views
I am working on a project whereby I would like to generate a report which has the ability to have a drop down list of users, such that the data in the report changes depending upon the user being selected. I'm looking at this from an admin perspective. I know how to create such a view for request.user, but I'm not entirely sure how to create the functionality for a drop down list of users and then the output changes. Any thoughts as to how to do this? I do have an example of existing code I can provide to show what I am trying to achieve; however it won't necessarily answer my question. Best, Neil -

Django-Docker: django.db.utils.OperationalError: could not translate host name "db" to address: Name or service not known
First-time docker-user: I recently added a cron job to my Django project and dockerized it. When I run docker-compose up --build, the system builds and runs the cron job, which exits with a code 137 (which is expected, since I'm running locally). When I try to run the cron job manually to troubleshoot methods of lowering the cron's CPU usage, I am met with: django.db.utils.OperationalError: could not translate host name "db" to address: Name or service not known This error is odd to me, since everything is fine upon build, but it seems like the command no longer knows what the database is outside of the build even with the project running. Also, does this mean my cron job can't execute in its designated time The following are links to similar posts that may be helpful to others with a similar issue, but have not solved my problem: Why this error, docker operational error (django project)?

Assign model permissions of Model1 to a Model2 in django using django guardians
I am using Django Guardians in my project and it works fine so far, but there is some problem: I need to assign permissions from model1 to the instance of the model2. Real example: The shop has some contracts and the shop owner wants to assign his employees permission to change contract fields (e.g. field1). So we have 3 models now: Shop, Contract, and User, and each model has it's own defined permissions per field like: can_change_field1, ... All permissions that employee can have must be related to the Shop model because when a shop owner assign contract permissions to his employee (to change field1 in contract in shop1), it mustn't affect another shop (So user will not be able to change that field e.g. field1 in shop2,...). 1st solution can be: to create all permissions in shop model (for all models: Contract,...). But it seems kinda of messy to me. What do you think? Please, Can you suggest some nice solution to this problem? -
angular display status_text differently on local vs prod
I have a simple login method in angular that calls the service API and I want to display the error to the alert service. However, the response parsed from the server is not same local vs prod in cloud environment. this.authService .login(this.f.username.value, this.f.password.value) .pipe(first()) .subscribe({ next: () => { // get return url from query parameters or default to home page this.alertService.success("Login successful"); const returnUrl = this.route.snapshot.queryParams['returnUrl'] || '/'; this.router.navigateByUrl(returnUrl); }, error: (error) => { this.alertService.error(error); this.loading = false; }, }); this works well locally the response shows { "headers": { "normalizedNames": {}, "lazyUpdate": null }, "status": 401, "statusText": "Unauthorized", "url": "http://localhost:4200/api/v1/token/", "ok": false, "name": "HttpErrorResponse", "message": "Http failure response for http://localhost:4200/api/v1/token/: 401 Unauthorized", "error": { "type": "client_error", "errors": [ { "code": "no_active_account", "detail": "No active account found with the given credentials", "attr": null } ] } however, in prod it is giving me different statusText somehow { "headers": { "normalizedNames": {}, "lazyUpdate": null }, "status": 401, "statusText": "OK", "url": "https://remoteurl-cloudrun-app/api/v1/token/", "ok": false, "name": "HttpErrorResponse", "message": "Http failure response for https://simpledc-tkbsnc6b4a-uc.a.run.app/api/v1/token/: 401 OK", "error": { "type": "client_error", "errors": [ { "code": "no_active_account", "detail": "No active account found with the given credentials", "attr": null } ] } I can't understand why. … -

Django Admin Dropdown Filtering: Show Exam Class Related Students in Student Assign Field
I'm working on a school management system using Django, and I'm currently facing an issue with customizing the behavior of dropdown fields in the Django admin interface. In my application, I have models for managing exams, students, and student results. Each exam is assigned to a subject, which is associated with a specific class and section. When I'm creating a student result entry in the admin panel, I want to ensure that the student_assign field only displays students who are part of the same class as the exam subject. More specifically, when I select an ExamAssign in the admin form, I want the related student_assign dropdown field to dynamically filter and display only those students who are associated with the same class as the selected exam subject. If I Select Class 10 here I want only to show the related class students (not only the section) here. I've tried implementing this using a custom admin form and overriding the __init__ method, but I'm encountering issues with getting the related students based on the selected exam's subject. Could anyone guide me through the correct way to achieve this functionality? I'd greatly appreciate any help or advice on how to properly filter … -

Make Django DB Transaction Idempotent on an External Call
I'm using a Django DB with a Postgres backend. Each user has a "balance" associated with their DB object, which is their current funds in the system. They can cash out the balance via gift cards, which is done by sending a POST request to Amazon's API. I perform two operations when the cash out their balance: Update the DB to set their balance to 0 Send a POST request to the Amazon API to generate a gift card for their balance If only one of these operations happen, that's very bad, for obvious reasons. I know you can use Transactions to make sure multiple database operations happen atomically -- is there a way to do something similar with a DB operation and an external call like this? -

Customize Form for User adding/editing in admin Wagtail
I have customized user profiles in Wagtail by adding fields (drm, cpm). How can I modify the form, or more specifically, the values in the form's lists based on the currently logged-in user and their permissions? Hello everyone, I have customized user profiles in Wagtail by adding fields (drm, cpm). How can I modify the form, or more specifically, the values in the form's lists based on the currently logged-in user and their permissions? For example, let's say you have extended the user profile model in Wagtail to include custom fields drm and cpm, and you want to dynamically populate a choice field in a form based on the user's role or permissions. Here's how you might approach this: # in models.py from django.db import models from wagtail.users.models import UserProfile class CustomUserProfile(UserProfile): drm = models.CharField(max_length=50, blank=True, null=True) cpm = models.CharField(max_length=50, blank=True, null=True) Next, you can create a custom form for a Wagtail admin page and override the form fields based on the user's profile: # in admin.py from wagtail.contrib.modeladmin.options import ModelAdmin from wagtail.contrib.modeladmin.views import CreateView, EditView from wagtail.contrib.modeladmin.helpers import PermissionHelper from .models import CustomUserProfile class CustomUserProfilePermissionHelper(PermissionHelper): def user_can_edit_obj(self, user, obj): # Customize this method to check if the user has … -

Django - Form Not Saving Image on Form Submission
For my current ModelForm for some reason all the fields get updated on a form submission as they are supposed to except for the image field. What’s the best solution to get this working with my current code? I think it’s because request.FILES isn’t getting handled correctly in my views.py file but not 100% sure. Side note: If i upload an image to the Django backend, the image field updates how it’s supposed to. This is only happening when there’s a form submission on the front end when the image field isn’t getting updated. Below is my code. Screenshots attached of the Django admin backend and the front end where the data is being displayed. Any help is gladly appreciated.

Votes not being counted in django poll

Error while migrating from a SQLite database to a MySQL database in a Django Project
I'm trying to migrate all of the data in my SQLite database to a new MySQL database, to do so, I've been following the following steps (which I found in another question What's the best way to migrate a Django DB from SQLite to MySQL?). I've tried the following approaches: First I run a py manage.py dumpdata > datadump.json. Then, I change my settings.py file to use my new MySQL database. After that, I run a py manage.py migrate --run-syncdb And then I exclude contentType data by: python manage.py shell from django.contrib.contenttypes.models import ContentType ContentType.objects.all().delete() quit() And Lastly, I try to run a py manage.py loaddata datadump.json I've also tried to just run py manage.py dumpdata --exclude contenttypes --exclude auth.permission --exclude sessions --indent 2 > dump.json, followed by py manage.py loaddata dump.json. The problem is that, in both approaches, in the very last step, when I'm trying to load the data into my new database, the following error is raised: UnicodeDecodeError: 'utf-8' codec can't decode byte 0xff in position 0: invalid start byte I've been trying to investigate what could prevent or fix this error but nothing has come up.

MS auth - Django adding an 'http' to my URI at callback
I am building a PoC for web applications using Django with Microsoft Authentication. The app in my Azure Directory is all setup, my Site domain matches the URI expected in the app and an initial call was made successfully. BUT, for reasons unknown to me, django sends an additional 'http://'. the error it gives me I am no Django or Azure expert. Here are some snippets. settings.py: AUTHENTICATION_BACKENDS = [ 'microsoft_auth.backends.MicrosoftAuthenticationBackend', 'django.contrib.auth.backends.ModelBackend' ] MICROSOFT_AUTH_CLIENT_ID = env('MS_APP_ID') #the keys are correct in the .env, triple-checked MICROSOFT_AUTH_CLIENT_SECRET = env('MS_SECRET_KEY') MICROSOFT_AUTH_TENANT_ID = env('MS_TENANT_ID') MICROSOFT_AUTH_LOGIN_TYPE = 'ma' MS_AUTH_REDIRECT_URI = 'http://localhost:5000' #matches the redirect URI in the Azure app accounts/urls.py: urlpatterns = [ path('microsoft/', include('microsoft_auth.urls', namespace='microsoft')), path('', RedirectView.as_view(url='index'), name='home'), path('accounts/', include('django.contrib.auth.urls')), path('index/', index, name='index'), ] I tried changing the domain url in the 'admin/sites/sites' and in the settings.py variable MS_AUTH*_*REDIRECT_URI, removing the 'http://' prefix, but to no avail.
