How to retrieve value in Dropdown list on edit button in Django
I have a form (edit_city.html) where I want to edit my record, there is also one dropdown field in which data is retrieving from another model name Country. How can I get the exact value in dropdown field, when I click on edit. class Country(models.Model): CountryID = models.AutoField(primary_key=True) CountryName = models.CharField(max_length=125, verbose_name="Country Name") def __str__(self): return self.CountryName class City(models.Model): CityID = models.AutoField(primary_key=True) CityName = models.CharField(max_length=125, verbose_name='City Name') Country = models.ForeignKey(Country, verbose_name='Country Name', on_delete=models.CASCADE) def __str__(self): return self.CityName views.py def Edit_City(request, id): city = City.objects.get(CityID=id) country = Country.objects.all() context = { 'city':city, 'country':country, } return render(request, 'City/edit_city.html', context) edit_city.html <form method="post" action="{% url 'update_city' %}"> {% csrf_token %} <div class="row"> <div class="col-12"> <h5 class="form-title"><span>Edit City</span></h5> </div> {% include 'includes/messages.html' %} <div class="col-12 col-sm-6"> <div class="form-group"> <label for="">Country</label> <select class="form-control" name="country_id" required> <option>Select Country</option> {% for con in country %} <option value="{{con.CountryID}}">{{con.CountryName}}</option> {% endfor %} </select> </div> </div> <div class="col-12 col-sm-6"> <div class="form-group"> <label>City Name</label> <input type="text" class="form-control" name="city_name" value="{{city.CityName}}" required> <input type="text" class="form-control" name="city_id" value="{{city.CityID}}" required hidden> </div> </div> <div class="col-12"> <button type="submit" class="btn btn-primary">Update City</button> </div> </div> </form> -
Fetch API key from Django to React app in a secure way
I am building an app at the moment and security is a priority so I want to ensure I'm implementing API fetches correctly. I currently have stored an API key in a .env file in Django. I want to use this key to perform requests through the frontend. django-app/.env API_KEY = key settings.py import os from dotenv import load_dotenv, find_dotenv load_dotenv(find_dotenv()) SECRET_KEY = os.environ['API_KEY'] I'm only just getting into backend development so I'm unsure of how to produce a view that would allow the frontend to use this key safely. Any tips or pointers will be much appreciated, thank you -
Django get_next_in_order and get_previous_in_order return incorrect data when objects are stored in non-default database
When using get_next_in_order and/or get_previous_in_order with a database other than the default, I get the following error: models.Car.DoesNotExist: Car matching query does not exist. Django Framework version is 4.1.1 Python version 3.8 models.py: from django.db import models class Person(models.Model): name = models.CharField(max_length=100, unique=True) class Car(models.Model): name = models.CharField(max_length=100) owner = models.ForeignKey(Person, models.CASCADE) class Meta: order_with_respect_to = "owner" In settings.py under DATABASES the following is used: DATABASES = { 'default': { 'ENGINE': 'django.db.backends.sqlite3', 'NAME': BASE_DIR / 'db.sqlite3', }, 'other': { 'ENGINE': 'django.db.backends.sqlite3', 'NAME': BASE_DIR / 'db_other.sqlite3', } } This can be tested in the Django Shell using the following command python manage.py shell: >>> from models import Person, Car >>> carowner = Person.objects.using("other").create(name="carowner") >>> porsche = Car.objects.using("other").create(name="porsche", owner=carowner) >>> ferrari = Car.objects.using("other").create(name="ferrari", owner=carowner) >>> lamborghini = Car.objects.using("other").create(name="lamborghini", owner=carowner) >>> carowner.set_car_order([lamborghini.pk, ferrari.pk, porsche.pk], "other") >>> gnio = porsche.get_next_in_order() >>> gnio.name # Should print ferrari >>> gpio = porsche.get_previous_in_order() >>> gpio.name # Should print lamborghini -
how to handle line breaks with django and js
I store in my db.sqlite3 of django some patterns which can contain a line break (\n). On the /admin page you can still see them.

Using both aria-hidden="true" and aria-labelledby attributes in the same field
I understand the functionality of both aria-hidden="true" attributes and aria-labelledby in the sense that the prior attribute hides the contents of an element and its child-elements from screen-readers (supposedly including aria-labelledby and aria-labelled), and that the latter attribute gives an element its accessible name based on another element's aria-label. However, I am faced by a contradiction in a Django course I am completing. https://youtube.com/clip/UgkxN1rhn70sw6fPvRdhpAFZv0KnPBz7J5-y (I have also attached a snippet of the uncompleted code below.) Here, the creator of the course includes both aria-hidden="true" attributes and aria-labelledby attributes simultaneously. According to what I understood, the inclusion of aria-labelledby makes no difference. So what is the point of including it? TLDR: Does the data of aria-labelledby still appear in screen readers when aria-hidden="true" or did the course creator make a mistake? <div class="modal" id="#myModal{{student.id}}" tabindex="-1" aria-labelledby=""> <div class="modal-dialog" role="document"> <div class="modal-content"> <div class="modal-header"> <h5 class="modal-title">Modal title</h5> <button type="button" class="btn-close" data-bs-dismiss="modal" aria-label="Close"> <span aria-hidden="true"></span> </button> </div> <div class="modal-body"> <p>Modal body text goes here.</p> </div> <div class="modal-footer"> <button type="button" class="btn btn-primary">Save changes</button> <button type="button" class="btn btn-secondary" data-bs-dismiss="modal">Close</button> </div> </div> </div> </div> -

Is it possible to sub-parametrize pytest parameters values?
I'm working on a DRF (REST API) project and I'm using pytest. Quite often I find myself writing almost identical test parameters and I've been wondering if there's something I'm missing.

Semgrep: A scalable way of catching all cases in a multiline f-strings
I have some logs in my codebase that have multiline f-strings, such as: ... logger.error( f'...' f'...' f'...' f'...' f'...' f'...' ) And some only have two f'...'s on separate lines while others 3 f'...'s, and so on. I am currently duplicating patterns to catch such logs. For example: ... patterns: - pattern-either: - pattern: | logger.$METHOD( f'...' f'...' f'...' ) - pattern: | logger.$METHOD( f'...' f'...' f'...' f'...' f'...' ) Catch those with 3 and 5 f'...'s on multiple lines. I have to write another pattern for those with 4, 2 and so on. Is there a scalable way to capture all of these with fewer patterns? The current implementation won't scale as there might be logs with 6, 7, 8, 9 and so on multiline f-strings. -
Django orm subquery - in clause without substitution
I need to build a query using Django ORM, that looks like this one in SQL: select * from A where id not in (select a_id from B where ... ) I try to use such code: ids = B.objects.filter(...) a_objects = A.object.exclude(id__in=Subquery(ids.values('a__id'))).all() The problem is that instead of nested select Django generates query that looks like select * from A where id not in (1, 2, 3, 4, 5 ....) where in clause explicitly lists all ids that should be excluded, making result sql unreadable when it is printed into logs. Is it possible to adjst this query, so nested select is used? -

The function get_form_kwargs doesn't work, it doesn't return anything
I have a CreateView and i want to save as a kwarg the user, and i don't understand what is wrong with my code. I wrote my get_form_kwargs in my create view(this is from my view.py): class ItemCreateView(CreateView): template_name = 'menus/form.html' form_class = ItemForm def form_valid(self, form): instance = form.save(commit=False) instance.user = self.request.user return super(ItemCreateView, self).form_valid(form) def get_form_kwargs(self): kwargs=super(ItemCreateView, self).get_form_kwargs() kwargs['user']=self.request.user return kwargs def get(self, request, *args, **kwargs): form = self.form_class(initial=self.initial) context = { 'form' : form, 'var' : 'Add an Item' } return render(request, self.template_name, context) I introduced the init function in my form(this is my form.py): class ItemForm(forms.ModelForm): class Meta: model = Item fields = [ 'name', 'article', 'description', 'exceptions', 'bl', ] def __init__(self,*args, **kwargs): print(kwargs.pop('user', None)) super(ItemForm, self).__init__(*args, **kwargs) The problem is that the print from the init function returned None value. It should returned the user. I'm mentioning that I am logged in. I don't understand what is wrong here. Thanks in advance for your help !!! -
