How to add multiple entry to multiple model which have one to one relationship in django?
So I have these two models class Question(models.Model): question_image = models.ImageField(upload_to="Questions/images", default="") subject = models.CharField(max_length=100) topic = models.CharField(max_length=100) type = models.CharField(max_length=100) exam_type = models.CharField(max_length=100) date_asked = models.DateField(default="") class Option(models.Model): question_id = models.ForeignKey(Question, on_delete=models.CASCADE) text = models.CharField(max_length=100) text.null = True text.blank = True option_image = models.ImageField(upload_to="Options/images", default="") option_image.null =True option_image.blank =True is_correct = models.BooleanField() You see the question has one two many relationships with the options Now I want to add question and corresponding to that question multiple options in the option table. So if a question with id=1 will have multiple option in option table with question_id = 1. So I have made these two forms from django import forms from practice.models import Question from practice.models import Option from django.forms import ModelForm class QuestionForm(ModelForm): class Meta: model = Question fields = ['question_image', 'subject', 'topic', 'type' , 'exam_type' , 'date_asked'] class OptionForm(ModelForm): class Meta: model = Option fields = ['text' , 'option_image' , 'is_correct'] Now in the HTML template in frontend I want to be able to add as many options I want so I have written this HTML code. The javascript code required to add more options is yet to be done but you get the point I am going … -
Dockerize Django and Celery tasks
I am trying to integrate Celery with an existing Django app using Docker. I have been trying to follow this tutorial (1). However, I keep bumping with the same error no matter what I try.

Usage of Django validators in nullable field
I have a model with a field: last_watched_episode = models.PositiveSmallIntegerField( null=True, ) And in this field I want to store either Null or positive integers gte 1 to max one that PositiveSmallIntegerField is able to hold (from 1 to 32767 ). I want to enforce validation on a model level ,so that I included full_clean() to save(): def save(self, force_insert=False, force_update=False, using=None, update_fields=None): self.full_clean() super(SeasonModel, self).save( force_insert=False, force_update=False, using=None, update_fields=None ) Problem is when I apply a MinValueValidator or custom validator to this field I get following error message: django.core.exceptions.ValidationError: {'last_watched_episode': ['This field cannot be blank.']} each and every time when saved value is omitted, that is it is NONE. This is quite logical as validator needs to have some input value to validate it Validator I use: def skip_if_none_none_zero_positive_validator(value: int) -> None: if value is None: return None elif value < 1: raise ValidationError( f'{value} must be greater or equal 1' ) Question is how it to overcome this issue? How to save None as a legit value and simultaniously validate that it would be greate or equal 1 in case values is not None? And enforce model level validation of course. -
django URL Trouble with passing parameter twice
I have a template where I pass all projects to and I loop through them and create a table that shows how many tasks are associated with each project. Then I have a button that says "Create new task for .

AJAX GET request not sending data to Django
I am trying to send data in localStorage via an AJAX GET request to Django, but the Django server never receives it. I am confident that I have data in localStorage("preselection") as console.log shows it. Here is my JavaScript snippet which is inside index.html (am a beginner, so apologies if this is basic and I'm avoiding jQuery for now): var preselection = localStorage.getItem("preselection"); function previous_selection () { if (localStorage.getItem("preselection") != null) { console.log("PRESELECTION IS: ", preselection); const data = new FormData(); data.append("preselection", preselection); const request = new XMLHttpRequest(); request.open('GET', '/'); request.setRequestHeader("X-CSRFToken", getCookie('csrftoken')); request.send(data); request.onload = () => { var url = '/prebasket'; window.location.href = url; }; return false; } } previous_selection(); Below is my view in views.py. I tried request.GET.dict(), request.GET.get(), request.GET.copy(), etc. and my data comes as JSON in case it matters, but Django just gets an empty {} or Null for q_preselection: @login_required def index(request): q_preselection = request.GET.dict() print(q_preselection) # comes back empty context = { #irrelevant } return render(request, "pizza/index.html", context) -

Django: multiple models with one-to-many relation on admin page TabularInline
I have multiple models in an existing database that all have a many-to-one relation to another model. For example: class Collection(models.Model): start = models.DateTimeField() end = models.DateTimeField(blank=True, null=True) class Meta: managed = False db_table = 'Program' class ItemA(models.Model): collection = models.ForeignKey( 'Collection', models.CASCADE, db_column='Collection_id') ... class Meta: managed = False db_table = 'ItemA' class ItemB(models.Model): collection = models.ForeignKey( 'Collection', models.CASCADE, db_column='Collection_id') ... class Meta: managed = False db_table = 'ItemB' What I want to do, is show these models in a single TabularInline on the admin page of the Collection model. I also want to be able to filter the models. Is this possible without inheritance in the database? (I don't want to add a general item table). In the documentation, I can only find how you can use TabularInline for a single model. So my question is basically: What would be the best approach to solve this? Is it maybe possible to define some kind of view model dat is not in the database, but that can be used to display all the items in a TabularInline? -

Token authentication for django channels
im trying to integrate React , django and django channels together , however im facing some trouble trying to authenticate the socket connection. There are some posts over here: first link enter link description here But they do not talk about how to utilize it over the front end portion. There are some posts which recommends to put the token within the URL , for example : WebSocket('wss://example.com/my-ws-endpoint/?token=' + token, ...) But there seems to be lots of security red flags in doing so. Therefore is there a simple easy way to resolve the token authentication issue for channel websockets here? -

Router not displaying correct URL in Django RestFramework?
This is how I defined urls.py file of my app router = DefaultRouter() router.register('hello-viewset', views.HelloViewSet, base_name='hello-viewset') router.register('profiles', views.UserProfileViewSet) router.register('schema', views.SchemaViewSet) router.register('creddefination', views.CredDefViewSet) router.register('overalltable', views.OverallViewSet) urlpatterns = [ path('', include(router.urls)), ] urls.py of Project: urlpatterns = [ path('admin/', admin.site.urls), path('api/', include('DIAPI.urls')), ] I am not getting correct address for creddefination. But when i manually go to http://127.0.0.1:7000/api/creddefination/ it is working. It is just not displaying correctly. What might be reason for this -
Get overview of SQL query count for every test in a test suite
I have a large Django application with tons of tests that need SQL query optimizations. I don't want to add assertNumQueries or django-assert-num-queries for each test individually, but instead produce an overview about how many SQL queries each one of all of the tests are triggering, to know which code needs the most optimization, like this: test | number of queries ------------------------------------------------ test_a.py::test_my_function1 | 5 test_a.py::test_my_function3 | 2 test_a.py::test_my_function5 | 7 Is it possible to configure a pytest hook in conftest.py which counts the number of SQL queries for each (DB) test and shows them in result - without the need to modify the source of my tests (like adding decorators)?
