Autocomplete dropdown for related-field filtering in Django admin
I'd like to have a nice autocomplete dropdown in my Django admin backend for filtering out results in the project model according to the subject attached to a person. this is my models.py: class Person(models.Model): subject = models.ForeignKey(Subject, on_delete=models.CASCADE, blank=True, null=True) class PersonRole(models.Model): project = models.ForeignKey('Project', on_delete=models.CASCADE) class Project(models.Model): person = models.ManyToManyField(Person, through=PersonRole) For now I managed to get a simple list using SimpleListFilter with the following code in admin.py: class PISubjectFilter(admin.SimpleListFilter): title = 'PI Subject' parameter_name = 'subject' def lookups(self, request, model_admin): return Subject.objects.values_list("id", "name").order_by("id") def queryset(self, request, queryset): count = range(1, 100) for x in count: if self.value() == str(x): return queryset.filter( person__personrole__person__subject=x ).distinct() break How can I turn this long list into a autocomplete dropdown? I've almost achieved what I want by specifying a custom template for my form in admin.py with template = "custom_form.html", with something like the below: {% load i18n %} {% load static %} <script src="https://code.jquery.com/jquery-3.7.1.min.js" integrity="sha256-/JqT3SQfawRcv/BIHPThkBvs0OEvtFFmqPF/lYI/Cxo=" crossorigin="anonymous"></script> <link href="https://cdn.jsdelivr.net/npm/select2@4.1.0-rc.0/dist/css/select2.min.css" rel="stylesheet" /> <script src="https://cdn.jsdelivr.net/npm/select2@4.1.0-rc.0/dist/js/select2.min.js"></script> <details data-filter-title="{{ title }}" open> <summary> {% blocktranslate with filter_title=title %} By {{ filter_title }} {% endblocktranslate %} </summary> <select id='select_subject' onchange="location = this.value;"> {% for choice in choices %} <option value="{{ choice.query_string|iriencode }}">{{choice.display}}</option> {% endfor %} </select> </details> … -
Using FormSet to editing a array of same form in django
My requirement to enable user to add description and remark against multiple files uploaded earlier.I am using formset to display a set of partial field data from a model 'medical_doc'.

Django post request is good in postman but not from frontend with the same payload
Django api interface and postman is working fine in posting the payload, however with the exact same payload posted from my frontend it doesn't work even while disabling cors. -This is my mode: `class Activity(models.Model): cid = models.CharField(max_length=10) percent = models.IntegerField() name = models.CharField(max_length=255)` -this is my view: class ActivityViewSet(viewsets.ModelViewSet): queryset = Activity.objects.all() serializer_class = ActivitySerializer def get_queryset(self): queryset = self.queryset # Start with the base queryset # Get the cid from the query parameters cid = self.request.query_params.get('cid') # If cid is provided in the query parameters, filter the queryset if cid: queryset = queryset.filter(cid=cid) return queryset -this is my url: `router.register(r'activities', ActivityViewSet)` And this is my frontend code: \` const postOutcomesAsync = async () =\> { function getCSRFToken() { const csrfCookie = document.cookie.match(/csrftoken=(\[\\w-\]+)/); if (csrfCookie) { return csrfCookie\[1\]; } return null; } const csrfToken = getCSRFToken(); axios.post('http://127.0.0.1:8000/activities/', inputValues[2], { headers: { 'Content-Type': 'application/json', 'X-CSRFToken': csrfToken } }); console.log('All activities posted successfully'); } \` The backend log shows OPTIONS 200 ok and no posting at all. Network tab shows post request failed but OPTIONS 200 ok. Axios shows network error 500. -

Ways to intercept error responses in Django and DRF
The problem: Django errors are values to details keys. Django Rest Framework (DRF) errors are values to detail keys. Therefore, having an application that raises both Django and DRF exceptions is inconsistent by default. I want a way to change the response errors so that they look like this: { "message": ..., "code": ... } Are there ways to handle both Django and DRF exceptions at the same time and respond with a custom response body? I have tried: custom exception handler in DRF, but this only handles DRF exceptions custom error messages when defining models email = models.EmailField(error_messages={"required": {"message": "", "code": 123}}) but Django can't handle a dictionary as a message Adding a DRF validator to my serializer: email = serializers.EmailField( validators=[ UniqueValidator( queryset=models.User.objects.all(), message={ "message": "a user with this email already exists", "code": status.EMAIL_EXISTS, }, ) ], ) but this does not override the response body, but instead it embeds the message as an error message to the {"details": {"message": {<embedded dictionary>}}} The only thing I believe would work, is to try-except all exceptions inside my Views, but I would like to know if there is a prettier way than placing all my Views inside try blocks. -
How to add a duplicate column to a table?

Unable to Save UserModel Data to Database Using Django Form
Problem: I'm encountering issues with my Django registration form where user data isn't being saved to the database. Details: I have implemented a Django registration form.

Trouble Integrating `django-simple-history` with `django-modeltranslation` in Abstract Model
I'm working on a Django project where I'm trying to create an abstract model that provides subclassed models with history tracking using the django-simple-history package. Additionally, I need to integrate django-modeltranslation for translating certain fields. However, I'm encountering issues with the integration. Here's my BaseModel code: from uuid import uuid4 from django.db import models from simple_history.models import HistoricalRecords class BaseModel(models.Model): class Meta: abstract = True history = HistoricalRecords(inherit=True) id = models.UUIDField(primary_key=True, default=uuid4, editable=False) created_at = models.DateTimeField(null=True, blank=True, auto_now_add=True) updated_at = models.DateTimeField(null=True, blank=True, auto_now=True) Now, I have a model TestModel that inherits from BaseModel: models.py class TestModel(BaseModel): text = models.CharField(max_length=100) un = models.IntegerField() new_text = models.CharField(max_length=100) And for translating fields in TestModel, I have the following translation setup: translation.py from modeltranslation.translator import register, TranslationOptions from test_app.models import TestDeleteModel @register(TestModel) class TestModelTranslationOptions(TranslationOptions): fields = ( 'text', 'new_text', ) However, the issue arises when django-simple-history doesn't recognize the translated fields like text_en, resulting in them not being added to the history model. It seems that this occurs because the translation fields are added after the simple history package registers the model and creates the history model. I attempted to register TestModel again with simple_history after the translation registration to address this: translation.py from … -
How to iterate a dict within a template that contains a key named items?
I have some fairly simple django template and part of it is iterating through some dict ( that originates from some parsed json files ) like: {% for k, v in d.items %} However my dict now contains an item called items, which because for the syntax of a.b django first tries to resolve it as a[b] before trying getattr(a,b) (and calling the result if its callable), will try to iterate through the value under that key instead of the dict. What would be a good way to resolve that? I know already I could write a filter that simply returns list(d.items()) but that seems wrong/wasteful to me. Are there some other possibilities to solve this problem? -
How to use websockets in drf project with react-frontend?
How to work with websockets in a split (backend/frontend) project? In a full Django project, I did it like this (1st answer): Dynamic updates in real time to a django template Now, the frontend is separate on React and the backend is on DRF. The frontend will be using socketio. How, in this case, should websockets be properly implemented in DRF? Should I still use channels? I thought that it could be done similar to the answer on Stack Overflow, where now the frontend is done in React instead of Django templates. But the frontend mentioned that endpoints are not needed, just events: For example, he will have something like socket.on("getTasks") and socket.on("addTask", task: {"new task"}). And I have no idea how to work with this All I've tried is the way from stackoverflow. -
Patch or update by search query axios
I have django restframework and control from javascript axios What I am doing is like this, axios.get(`http://localhost:8010/api/myusers/?my_id=${my_id}`).then((res)=>{ var id = res['data']['results'][0]['id']; axios.patch(`http://localhost:8010/api/myusers/${id}/`, { phone: 'nice phone', }).then((res)=>{ console.log("patch finish"); }) }) Fetch the id by my_id and patch the data.

How can I persist Django session after a POST request?
I want to be upfront with you the project I'm working with is kind of a mess, so I'm just looking for solutions. I have a Django app (no DRF) and a CI4 app. I want authentication to persist across the two apps. Basically, the CI4 app is the main, and that's where the user authenticates. I want to use request. Session in the Django app to handle the authentication state. I made the CI4 app sends a POST request to the Django app, and create a request. Session upon a successful authentication. @csrf_exempt def login_view_endpoint(request): if request.method == 'POST': username = request.POST.get('username') password = request.POST.get('password') user = Utilisateur.checkuser(username, password) if user: if 'utilisateur' not in request.session: request.session['utilisateur'] = user.id print(request.session['utilisateur']) return HttpResponse('true') else: return HttpResponse('false') else: # If the request method is not POST, redirect to the login page return HttpResponse('false') But the issue is when I test the flow of what I had in mind, I get redirected to the "login_page" of my Django app (which I'm trying to remove), which means the session doesn't exist, but the authentication was a success because I got a true response in my CI4 app. Maybe my understanding of session is … -

Efficient way to process data for number of views with dates
I am looking for a more efficient way to implement the provided code, which retrieves the number of views for object within a date range (start_date and end_date).

However, I believe there might be a more optimized approach.

Caching issue in Celery

The function works fine when I run it on the shell and all the results are correct. But when celery runs the task it gives (what I believe) cahced results.
