gradual migration of django monolith to async
I have huge django2 app (without django ORM) and I want to make it asynchronous. Right now i've come up with two strategies: upgrade to django 3/4 and migrate to async view by view add separate app (fastapi), migrate each view to the new app, and while migration is in progress split traffic between apps on load balancer level. the problem with first approach is that django will switch between sync and async mode and I will not see any improvements before migrating most of the views. the problem with second approach is that it is somewhat complicated and will require more code migrations and infra tinkering. any suggestions? -
Django Environment Identifying the DEBUG as False while it is set to True
I get and error CommandError: You must set settings.ALLOWED_HOSTS if DEBUG is False Below are the edits I attempted seeing at stackoverflow's suggestion from various (queries)[https://stackoverflow.com/questions/66923320/why-it-doesnt-set-debug-true] around 5 of them were relevant and tried to edit accordingly. ... I also checked for views and urls for any filename mistyping and typo errors. Yet I am getting CommandError: You must set settings.ALLOWED_HOSTS if DEBUG is False. I closed the session and changed the open .py file default from vscode and then with python. Yet this error is persistent PLEASE HELP My settings.py has DEBUG = TRUE ALLOWED_HOSTS = [] I have also tried ALLOWED_HOSTS = ['*'] then ALLOWED_HOSTS = ['localhost'] then ALLOWED_HOSTS = ['127.0.0.1'] then ALLOWED_HOSTS = ['localhost', '127.0.0.1'] once with DEBUG = FALSE and then with DEBUG = TRUE Alternately I Tried this TEMPLATE_DEBUG = DEBUG if not DEBUG: ALLOWED_HOST = ['0.0.0.0', '127.0.0.1','localhost','*'] ALLOWED_HOSTS = []``` The issue still persists despite Changing VS code settings .py extension change from VSCODE to Python interpreter and vice versa. -
Django circular import (models-views(-forms))
Watched all the previous related topics devoted to this problem, but haven't found a proper solution, so decided to create my own question. I'm creating a forum project (as a part of the site project). Views are made via class-based views: SubForumListView leads to a main forum page, where its main sections ("subforums") are listed. TopicListView, in its turn, leads to the pages of certain subforums with the list of active topics created within the subforum. ShowTopic view leads to a certain topic page with a list of comments. The problem manifests itself because of: Models.py: Method get_absolute_url in the model Subforum, which in its return section's reverse function takes a view as the 1st argument; I've tried to avoid a direct import of the view, but the program doesn't accept other variants; Views.py: most of the views have imported models either in instance arguments (model = Subforum), or in methods using querysets (like in get_context_data: topics = Topic.objects.all()); I can't surely say whether the change of instance argument model = Subforum to model = 'Subforum' really helps, as it's impossible to do with queryset methods and thus can't be proved; Forms.py: my form classes were created via forms.ModelForm and … -
Django: How to add objects to ManyToManyFields of multiple objects in a fast way?

We add each one of them to skills field of the provider. But the problem … -
How can I handle multiple separate models in a single AJAX request using Django REST Framework?
In my Django project (version 5.1.2), I need to handle data from multiple models in a single AJAX request from the front end. For example, I have a form that collects user information and shipping addresses at the same time. I want to submit this data in a single request and have it saved in separate models in the database. I’m using Django REST Framework to manage the API, but I’m unsure how to properly validate and save multiple models at once in one request. Currently, I am using one ViewSet per model, but I don’t know how to combine them in a single AJAX request and ensure that if there’s an error in one of the models, none of the data is saved (i.e., I want proper transaction handling). Is there a recommended solution for this in Django 5.1.2? What is the best way to handle multiple models in a single AJAX request in Django REST Framework? Details: I'm using Django 5.1.2. Both user and address information need to be saved transactionally. What I Tried: I created two separate ViewSets for the user information and shipping address models. Then, I tried to send the form data via a single … -

bin/bash logs screw up after running django query create - ÄDEBUGÅ instead [DEBUG]
When running this django command: MyObjectBase.objects.create( ..., report_pdf=open(f"{REPORT_PATH}/{file_name}.pdf", "rb").read(), ... ) My log output in the bin/bash console of VS Code in WSL2 on Win11 gets screwed. Instead before the command: [2024-10-21 13:40:52 +0200] [923356] [DEBUG] this is a debug message I am getting logs like: Ä21/Oct/2024:11:47:18 +0000Å ÄDEBUGÅ Backticks turn into 'é'. It looks like that during the create-command the binaries of the file are printed to the log like (just thousands of chars longer than this sample) ÖxecoÖxc6Öxd2ÖxffÖxd6ÖxffKÖx00xyÖxchÖxfaÖxe66Öx7fÖx98Ö This does not happen for every report, using different base data does not cause this effect. Unfortunately it is impossible for me to detect differences. I can say that the base data only contains strings and doubles and so on but no nested blobs or strings like code, but special chars like # are possible. I tried another terminal. tmux was available by default. It does not face this problems, logs stay fine. But not using (one of) the most default terminals is not a valid solution for me. So I am looking after the cause and hope to get it solved somehow. As an alternative I could imagine to suppress the binaries from the log when running django create. … -

Issue with updating read-only fields in Django admin: flags not saving
I’m working on a Django admin interface where certain fields (specifically, review status flags such as is_pending_review_section_title_en and is_pending_review_section_title_uk) should be marked as read-only in the admin interface, but still be updated programmatically when content changes. I’ve implemented the logic to dynamically determine the fields as read-only using the get_readonly_fields method inside an inline admin class (SectionInline). Although the fields correctly display as read-only in the interface, the problem arises when I try to update these fields in the save_model method of the PageAdmin class (or even in forms). The flags appear to be set correctly in the code, but they do not persist in the database after saving. Here is a summary of what I’ve tried: 1. Marked fields as read-only using get_readonly_fields — This works for the admin UI. 2. Tried updating the fields programmatically inside save_model in the PageAdmin class and verified the values through logging. The flags are set to True, but after saving, the values in the database remain unchanged. 3. Commented out form save logic to check if it’s interfering with saving, but the issue persists. 4. Ensured flags are not present in forms to avoid user interaction. What could be causing the fields … -

How to Send Authentication Token from Frontend using Both Fetch & Ajax to Restful API Backend?

How to Delete an Annotation Using Wagtail Review and Annotator.js on Button Click?
I am working with both Wagtail Review and Annotator.js in my project. I want to add a delete button (an "X" inside a red circle) to annotations, and when clicked, it should delete the corresponding annotation. I have added the delete button inside the annotation's controls, but I am struggling to properly trigger the deletion. What I have so far: I am using Annotator.js to create and manage annotations. The annotations appear on hover over the parent element (annotator-outer annotator-viewer). The delete button is injected dynamically inside the .annotator-controls span when the annotation becomes visible. I am trying to use the click event to trigger the annotation deletion, but I am not sure how to properly call the Annotator.js delete function or if I am handling the interaction correctly within Wagtail Review. Here’s the current approach I have: When the annotation parent (.annotator-outer.annotator-viewer) is hovered, I dynamically add the "X" delete button inside .annotator-controls. I attach a click event listener to the delete button. I expect the click to trigger the annotation deletion using Annotator.js. Code snippet: document.addEventListener('DOMContentLoaded', (event) => { function deleteAnnotation() { console.log('Delete function triggered!'); // Assuming annotator.js method is accessible to delete the annotation if (window.annotator && … -

Problem with testing Messages in Django 5 CreateView
I am writing unit tests of ebook catalog applications in Django 5. The book creation page uses the built-in CreateView.

I started doing this very laboriously, but figure there must be a simpler way. e.g., this gets the Person IDs and counts of how many times they've sent a Letter: senders = ( Letter.objects.order_by() .values(person_id=F("sender")) .annotate(count=Count("pk")) .distinct() ) I can do the same for recipients. Then combine the two into a single list/dict, adding the counts together. Sort that. Then inflate that data with the actual Person objects, and pass that to the template. But I feel there must be a less laborious way, starting, I think, with a single query to get the combined sent + received counts. -
