Integrating Vite (VueJs) frontend with Django Login Form
I am looking to understand how once it is checked that a user is authenticated using a django login form, how they can then be taken to a vue frontend made using vite? Many examples I have seen make use of webpack loader however, I am using vite. I am developing locally, so is it a matter of just directing the user to a local server url only if authenticated? The idea is depending on the authenticated user, certain information will need to be gathered associated with them. -
How to send audio file from front end to django backend through websockets for processing at the backend
I have made a website in django that uses websockets to perform certain tasks as follows : From frontend I want to take audio using MediaRecorder as input api through javascript I want to send this audio back to the backend for processing and that processed data is again send back through the connection in realtime. I have tried various things for the purpose but haven't been successful yet. The bytes data that I've been receiving at the backend when I'm converting that into audio then I'm getting the length and size of the audio file but not getting the content of the file. Means the whole audio is silent but the same audio which I'm listening in the frontend is having some sound. but I don't know what's happening at the backend with the file.

Isolation level doesn't change even if setting "SERIALIZABLE" to 'OPTIONS' in settings.py in Django
Following the documentation, I set SERIALIZABLE isolation level to 'OPTIONS' in settings.py for PostgreSQL as shown below. *I use Django 3.2.16 on Windows 11: # "settings.py" import psycopg2.extensions DATABASES = { 'default':{ 'ENGINE':'django.db.backends.postgresql', 'NAME':'postgres', 'USER':'postgres', 'PASSWORD':'admin', 'HOST':'localhost', 'PORT':'5432', }, 'OPTIONS': { # ↓ ↓ ↓ ↓ ↓ ↓ ↓ ↓ ↓ ↓ Here ↓ ↓ ↓ ↓ ↓ ↓ ↓ ↓ ↓ ↓ 'isolation_level': psycopg2.extensions.ISOLATION_LEVEL_SERIALIZABLE, }, } Then, I created person table with id and name with models.py as shown below: person table: id name 1 John 2 David # "store/models.py" from django.db import models class Person(models.Model): name = models.CharField(max_length=30) Then, I created and ran the test code of non-repeatable read which runs two transactions with two threads concurrently as shown below: # "store/views.py" from django.db import transaction from time import sleep from .models import Person from threading import Thread from django.http import HttpResponse @transaction.atomic def transaction1(flow): while True: while True: if flow[0] == "Step 1": sleep(0.1) print("<T1", flow[0] + ">", "BEGIN") flow[0] = "Step 2" break while True: if flow[0] == "Step 2": sleep(0.1) print("<T1", flow[0] + ">", "SELECT") person = Person.objects.get(id=2) print(person.id, person.name) flow[0] = "Step 3" break while True: if flow[0] == "Step 6": sleep(0.1) print("<T1", flow[0] … -

django htmx change hx-get url after user input from radio buttons
This is forms.py: class OrderForm(forms.ModelForm): def __init__(self, *args, **kwargs): super().__init__(*args, **kwargs) self.helper = FormHelper() self.helper.attrs = { "hx_get": reverse("planner:detail", kwargs={"slug": self.instance.venue}), "hx_target": "#services", } class Meta: model = Order fields = ["venue"] widgets = {"venue": forms.RadioSelect()} HTML: <div id="venue-options" class="p-3"> {% crispy form %} </div> This is the error when you click one of the radio buttons: The current path, planner/detail/None/, matched the last one. It says None/ because when you join the page none of the radio buttons are clicked so there is no slug to replace it. I need a way to replace None with the slug / id of the object chosen by the user. I need the url to be changed everytime the choise is changed. I am open to using apline.js but i would like a way of doing it in htmx/django. Thank you so much. -

Hide specific field in drf_yasg django swagger documentation
I have a project with drf_yasg, there is a serializer with a to_internal_value method which is writing a field('mobile_operator_codes') for me. The field is overriden, so we don't need to input it in request. Though we need to output it in response. Documentation(drf_yasg) takes fields='all' and writes everything in request, though we don't need the 'mobile_operator_codes' in request blog. We don't expect it in the request. Serializer is as follows: class ClientSerializer(serializers.ModelSerializer): tags = ClientTagsField(required=False) mobile_operator_code = serializers.CharField(required=False) class Meta: model = Client fields = '__all__' def to_internal_value(self, data): data_overriden = data.copy() if 'phone' in data: data_overriden['mobile_operator_code'] = get_operator_code_from_phone(data['phone']) return super().to_internal_value(data_overriden) View is as follows: class CreateClientView(mixins.CreateModelMixin, generics.GenericAPIView): serializer_class = ClientSerializer def post(self, request, *args, **kwargs): return self.create(request, *args, **kwargs) Model: class Client(models.Model): phone = models.CharField(max_length=11, verbose_name="номер телефона клиента") mobile_operator_code = models.CharField(max_length=3, verbose_name="код мобильного оператора") tags = models.JSONField(null=True, blank=True, verbose_name="теги") timezone = models.CharField(max_length=50, verbose_name="временная зона") # https://en.wikipedia.org/wiki/List_of_tz_database_time_zones def __str__(self): return str(self.phone) + ' ' + str(self.tags) if self.tags else str(self.phone) Swagger documentation: swagger documentation What I tried: read_only in field makes this field not writeble by to_internal_value excluding the field from fields just puts empty value in it(given (required=False)) you cannot use different serializer, because you will still have to … -
Django forms: how to use optional arguments in form class
I'm building a Django web-app which has page create and edit functionality. I create the page and edit the pages using 2 arguments: page title and page contents. Since the edit and create code is very similar except that the edit code doesn't let you change the title of the page I want to make some code that can do both depending on the input. This is the current code I'm using right now. class createPageForm(forms.Form): page_name = forms.CharField() page_contents = forms.CharField(widget=forms.Textarea()) class editPageForm(forms.Form): page_name = forms.CharField(disabled=True) page_contents = forms.CharField(widget=forms.Textarea()) I know that if I wasn't using classes, but functions I could do something like this: def PageForm(forms.Form, disabled=False): page_name = forms.CharField(disabled=disabled) page_contents = forms.CharField(widget=forms.Textarea()) PageForm(disabled=True) PageForm(disabled=False) That is the kind of functionality I'm looking for^^ I tried the following: class PageForm(forms.Form): def __init__(self, disabled=False): self.page_name = forms.CharField(disabled=disabled) self.page_contents = forms.CharField(widget=forms.Textarea()) class PageForm(forms.Form, disabled=False): page_name = forms.CharField(disabled=disabled) page_contents = forms.CharField(widget=forms.Textarea()) Both didn't work and got different errors I couldn't get around. I was hoping someone could lead me in the right direction, since I'm not very familiar with classes. -

Comparing django database data with a custom python function not working (Django)
I'm trying to retrieve reserved appointments from database in Django and compare them with custom dates which I have created with a custom function. The problem is that it will work only for the first day and the other days it will copy the appointments from the first day. Please check the images and the code. I think the problem is when I compare using the for loop with jinja in template. {% for date in dates %} <div class="py-2 pr-4"> <button onclick="document.getElementById('id01').style.display='block'" class=""> {{date}}</button> <!-- The Modal --> <div id="id01" class="w3-modal"> <div class="w3-modal-content"> <div class="w3-container"> <span onclick="document.getElementById('id01').style.display='none'" class="w3-button w3-display-topright">&times;</span> <h1 class="font-medium leading-tight text-5xl mt-0 mb-2 text-black">Not Available</h1><br><br> <!--Displaying Timeslots--> <!--I think that the problem is here --> {% for a in app %} {% if a.date|date:"c" == date%} {{a.time}}<br> {% endif %} {% endfor %} <br><br> </div> </div> </div> </div> {% endfor %} Please also see the images . all dates generated this appointments are reserved only on the first date,but appears in each date -

Django Templates Not Updating with CSS Changes
I am currently working on a project using Django and Django Templates, and this also is my first time ever using Django. For this project, I had to overhaul a lot of the design and change a lot of the CSS in the static files. I had previously been running the server on the same Google profile for a while. However, after completing my changes, and running the server on that same Google profile, none of the changes I've made is displayed. However, when I run the server on a guest account, change my Google profile, or run the server on Safari, the changes show. I'm curious to know why this is happening. -

Filtering on multiple fields in an Elasticsearch ObjectField()
I am having trouble figuring out the filtering syntax for ObjectFields() in django-elasticsearch-dsl. In particular, when I try to filter on multiple subfields of the same ObjectField(), I'm getting incorrect results. For example, consider the following document class ItemDocument(Document): product = fields.ObjectField(properties={ 'id': fields.IntegerField(), 'name': fields.TextField(), 'description': fields.TextField() }) details = fields.ObjectField(properties={ 'category_id': fields.IntegerField(), 'id': fields.IntegerField(), 'value': fields.FloatField() }) description = fields.TextField() I want to find an Item with a detail object that has both category_id == 3 and value < 1.5, so I created the following query x = ItemDocument.search().filter(Q("match",details__category_id=3) & Q("range",details__value={'lt':1.5})).execute() Unfortunately, this returns all items which have a detail object with category_id==3 and a separate detail object with value < 1.5 e.g. { "product": ... "details": [ { "category_id": 3, "id": 7, "value": 20.0 }, { "category_id": 4, "id": 7, "value": 1.0 }, ... ] } instead of my desired result of all items that have a detail object with both category_id==3 AND value < 1.5 e.g. { "product": ... "details": [ { "category_id": 3, "id": 7, "value": 1.0 }, ... ] } How do I properly format this query using django-elasticsearch-dsl? -

When the pipeline job runs I am getting denied: requested access to the resource is denied error on BitBucket. What did I not do correctly? Thanks.
