In Bootstrap 5 why select options doesn't appear in every browsers?
I'm made a page where the user have to choose an options from the dropdown list where other users that matches to a criteria appears. Almost every cases it works well but some users (they are using Chrome or Edge) made a feedback that the options are in the dropdown list but the text has the same color like the background so it is appears just when they hover it like on the image below. In the most of the cases everything works fine and all the names appear. I don't used any any CSS just Bootstrap 5 and Django. <h3 class="mt-4">This is the questions label</h3> <select class="form-select" aria-label="" name="perf01a" id="perf01a"> <option id="opt">nincs</option> {% for u in related_users %} <option>{{ u.user_name.last_name }} {{ u.user_name.first_name }}</option> {% endfor %} </select> <select class="form-select" aria-label="" name="perf01b" id="perf01b"> <option id="opt">nincs</option> {% for u in related_users %} <option>{{ u.user_name.last_name }} {{ u.user_name.first_name }}</option> {% endfor %} </select> <select class="form-select" aria-label="" name="perf01c" id="perf01c"> <option id="opt">nincs</option> {% for u in related_users %} <option>{{ u.user_name.last_name }} {{ u.user_name.first_name }}</option> {% endfor %} </select> What should I do? -
Making a django site that is vulnerable to session hijacking
For a cybersecurity demo, I need to create a website that is vulnerable to session hijacking simply by sniffing a session cookie and integrating it in the attacker's requests' headers. I have tried using many implementations of jwt authentication, and also to simply steal the "sessionid" after having set SESSION_COOKIE_SECURE to "False". I was never able to steal the sessions on my website and would always get redirected to the login page. Can you think of any vulnerable public session cookie mechanism I could implement to steal a session on my django website simply by adding it to my requests' headers ? Thank you very much. -

How to return rendered html I received from a 3rd party api call in Django?
The frontend requests the /oauth endpoint from our backend. The backend makes a request to a third party, and they return some html to our backend. Is there a django Response method that allows me to return this html, rendered, to the frontend? Something like: url = '3rd/party/url' response = requests.get(url) return Response.render(response.content) I am somewhat new to python/django, so any advice would be lovely. Thank you! -
Django Dynamic Dropdown Menu Not Populating
I'm working on a project where the task is to implement a dynamic drop-down menu where the choices in the menu will change depending on the value that the user selects from a previous drop-down menu. I have the first dropdown menu populated with the values of the name keys in the JSON below (Network 1, Network 2, etc.). My goal is that the second dropdown will populate with a list of the zone values that correspond with the name value that the user selects in the first dropdown. So, if the user selects Network 1 from the first dropdown, the second dropdown will populate with network.1.private.zone as its only option. If the user selects Network 2 from the first dropdown, then the second dropdown will populate with network.2.private.zone as its only option, and so on. Thanks in part to this guide, I've made quite a bit of progress on this. I can see the AJAX request firing in the browser, and the url and networkId values seem to be correct when I console.log them to the browser. But I can't figure out why the dynamic dropdown menu isn't populating. Here is a screenshot of what the page looks like: … -
Django - CKEditor5Field field default font color
I've got 2 CKEditor5Fields in one of my models. I'm running into an issue in the admin panel that when the browser is in dark mode the background color of the field is staying white and the font color is changing to an off-white color making it really hard to read. The text is fine when it's rendered to the page. Is there a way to set the default font color to black so browser mode doesn't matter?

how to send one section's field id to another section for the output
currently I'm making an 'django' app which has functionality of wizard form, in which I want output from first section of wizard form (which has dropdown list) to last section of the wizard form. To clarify more first section has only one dropdown list (sms, whatsapp, twitter, facebook, instagram, etc..), in second section also dropdown list (which has a department lists which means from which department you want to send...), in third section it should be dynamic and that will be depends on the first section of my wizard. For exaple if i select sms then in 3rd section it should show section which is specifically designed for sms and like wise. So, how should i do that?, if you still don't understand contact- captionamerica1112@gmail.com -

I can't FK them together, because these apps exist in multiple projects (some without each other) so it would break other projects. This is an unmanaged model from appA - which uses a different database which we will call databaseA for this example; in a perfect world 'location_id' would be the FK but as I've described above, it cannot be. class Enrollment(models.Model): id = models.IntegerField(db_column="ID", primary_key=True) location_id = models.IntegerField(db_column="locationID") grade = models.CharField(db_column="grade", max_length=10) student_count = models.IntegerField(db_column="studentCount") class Meta(object): managed = False db_table = "mytable_Enrollments" This is a managed model from appB which uses databaseB (which is the primary database used by the rest of the apps in this project); the 'pk' or 'id' of this model is what is listed in the Enrollment model under location_id class Location(models.Model): name = models.CharField(max_length=50) alternate_name = models.IntegerField() If I want to get Enrollment objects for a Location, I have to explicitly put a number in for the id like so: location = Location.objects.get(id=1) enrollments = Enrollment.objects.filter(location_id = location.id) But I'm trying to annotate the 'total_student_count' onto the Location model like so: enrollments = ( Enrollment.objects.filter(location_id=OuterRef("pk")) .order_by() .values("location_id") ) … -

django request in render to string template
I used to think, request is global variable that can always be accessed in template. until, I defined a property on model instance, and returns render_to_string template. class Profile(models.Model): user = models.OneToOneField(User, on_delete=models.CASCADE) def card(self): return render_to_string('common/user_card.html', {'user': self.user}) user_card.html {% if request.user == user %} {% elif request.user in user.profile.follower.all %} <span href="{{ user.pk }}" class="user-follow not-followed">unfollow</span> {% else %} <span href="{{ user.pk }}" class="user-follow followed">follow</span> {% endif %} for the result, request is always None and the conditional always jump to else. the request keyword is not picked up by render_to_string, should it be global in any template since we must have a request to return something? I cannot believe it, in many other template I have things defined like: {{ user.profile.card }} I have no idea on what to do now, is there a way to make request always a keyword in any html template? this is such a bad feature that request is not available in render_to_string template which we cannot check who is requesting the page. -
Django throws an error while trying access registration page
Django throws the following at me while I try to access the signup page.. The view accounts.views.signup_view didn't return an HttpResponse object. It returned None instead. I think everything was done right but apparently django doesn't agree. Signup.html <h3>Register</h3> <form method="POST" action=""> {% csrf_token %} {{form.as_p}} <input type="submit" name="Create User"> </form> views.py from django.shortcuts import render, redirect from django.contrib.auth.forms import UserCreationForm # Create your views here. def signup_view(request): if request.method == "POST": form = UserCreationForm(request.POST) if form.is_valid(): form.save() context = {'form': form} return render(request, 'signup.html', context) -

Django UniqueConstraint on Distant Model
I have models like this. The basic relationship is that auth.Group can have multiple Projects, and multiple Orders can be associated with each Project. Simplified version: from django.db import models class Project(models.Model): group = models.ForeignKey("auth.Group", on_delete=models.SET_NULL, null=True) class Order(models.Model): project = models.ForeignKey(Project, on_delete=models.CASCADE) external_id = models.CharField(max_length=255) The Orders have external_ids that relate them to another system. Those should be unique at the auth.Group level. I know that I can do this: class Order(models.Model): group = models.ForeignKey("auth.Group", on_delete=models.SET_NULL, null=True) project = models.ForeignKey(Project, on_delete=models.CASCADE) external_id = models.CharField(max_length=255) class Meta: constraints = ( models.UniqueConstraint( fields=["group", "external_id"], name="unique_external_id_per_group" ), ) But I don't want to replicate the group relationship on the order. I tried this: class Meta: constraints = ( models.UniqueConstraint( fields=["project.group", "external_id"], name="unique_external_id_per_group" ), ) and: class Meta: constraints = ( models.UniqueConstraint( fields=["project__group", "external_id"], name="unique_external_id_per_group" ), ) But I just get 'constraints' refers to the nonexistent field 'project.group'. -
Django: Append json data to Response object
New to Python/Django. I am wanting to conditionally append json data to a Response object if a particular filter is present in my request, all within the same json array. There is also standard information I want to return in every response. For example, I have: filter = request.GET['filter'] response = Response({'services': []}) if filter == 'service1': response.data['services'] = {'service1': service_data.get('service1')} response.data['connectivity'].add|append|something({'base_service_data': service_data.get('base')}) return response I can't seem to find a way of appending to this services array, only assigning and therefore overwriting what was there before. Can this be done? The goal is to allow filter to be a list, and have a number of services appended to services.
