Django forms out as UL and not DIV
Just upgraded my Django app from version 3.2 to version 4.1. When I now render a form with multiple choices it renders each item as a div and not li. Sample code as follows: from django import forms CHOICES = [] for i in range(1, 20): CHOICES.append((str(i),str(i))) class ChoicesForm(forms.Form): choices = forms.MultipleChoiceField(required=False, widget=forms.CheckboxSelectMultiple(), choices=CHOICES) form = ChoicesForm() print(form) The output(shortened) of the print(form) is <tr> <th><label>Choices:</label></th> <td> <div id="id_choices"><div> <label for="id_choices_0"><input type="checkbox" name="choices" value="1" id="id_choices_0"> 1</label> </div><div> <label for="id_choices_1"><input type="checkbox" name="choices" value="2" id="id_choices_1"> 2</label> </div><div> <label for="id_choices_2"><input type="checkbox" name="choices" value="3" id="id_choices_2"> 3</label> </div><div> <label for="id_choices_3"><input type="checkbox" name="choices" value="4" id="id_choices_3"> 4</label> But what I was getting in my earlier code was <tr><th><label>Choices:</label></th><td><ul id="id_choices"> <li><label for="id_choices_0"><input type="checkbox" name="choices" value="1" id="id_choices_0"> 1</label> </li> <li><label for="id_choices_1"><input type="checkbox" name="choices" value="2" id="id_choices_1"> 2</label> </li> <li><label for="id_choices_2"><input type="checkbox" name="choices" value="3" id="id_choices_2"> 3</label> </li> <li><label for="id_choices_3"><input type="checkbox" name="choices" value="4" id="id_choices_3"> 4</label> I can't find any reference to why this would change. Nor can I figure out how to create my form output as a list and not Is this expected or is there something else I am missing ? What I ultimately want to achieve is to format the output as rows of items and not a column … -

how to pass the url into the view context in django?
page_title.html <!-- page title --> ... <ul class="list-inline custom-breadcrumb mb-2"> <li class="list-inline-item"><a class="h2 text-primary font-secondary" href="{% url 'teacher-list' %}">{{list_title}}</a></li> ... <!-- /page title --> views.py class TeacherDetailView(DetailView): model = Teacher context_object_name = "teacher" template_name = "users/teacher_detail.html" def get_context_data(self, **kwargs): context = super().get_context_data(**kwargs) context['list_title'] = "Our Teachers" return context So currently have a teacher_detail page, on that page there is a page_title section (which is being included inside other templates) which has a url that allows you to go to the list view version of it, in this case it is the teacher_list page. The problem is that i have multiple pages with similar design, i know how that i can pass in the list_view variable as a part of the view context which makes it dynamically displayed depending on the page. I wonder how i can also pass in the url as a dynamic variable into the view context like: context['list_url'] = "{% url 'teacher-list %}" so that i don't have to repeat it and also will be able to reuse the page_title sub template? -
Choosing framework for streaming video for better performance
I have a task to create an API for streaming images that my backend gets through a GRPC connection. The question is: what python framework is best suited for this job? I'd like to know if there is any framework that support having a single streaming response for multiple clients. I mainly use Django, but I've heard that it would be a bad choice for this kind of task since it'd allocate a separate process for every new connection, and that would result in bad performance. I've looked into websocket implementations with Django, but I'm still not sure what the best decision is for this kind of task. -
D3 bar chart returning height of "NaN"
I'm attempting to display a basic animated line-chart using D3 (v7) to my web page. This is being done from within a Django project and so my chart is being fed data from my views.py file. However, the chart only partially displays on the page. The x and y axis lines are displayed, along with the axis labels.

I removed all firewalls but still can not access my webpage via vpn
I am just got my first Raspberry Pi and decided to host little website project using Django. Everything was running smoothly until the firewall part. I was not sure why externally other can not access my webpage, I do not see any errors on host. I completely removed all firewalls on my host (by default Raspberry Pi had: iptables), also changed django project settings and allowed all hosts. But still can not access webpage through mobile internet, vpn or though friends phone. Not sure what is going on. Website is accessible through devices that are connected to my wifi. But I though removing all firewalls will allow access to any device. This is how I deleted iptable from my host I also noticed message mentioning about replacing iptable with nftable. Just in case I also removed nftable, which should leave my webpage totally naked and without firewall protection. But still can not access it 😔 In case you missed I am using: Raspberry Pi Zero W OS: Linux raspberrypi 6.1.19+ #1637 Tue Mar 14 11:01:56 GMT 2023 armv6l GNU/Linux Project: Django 2.2.19 Note: Nginx and Gunicorn works perfectly fine.

Django. Adding fields to the model through the admin panel
How to make a model (for example, "Brigade"), the composition of which can be expanded when creating an instance in the admin panel? We don't know in advance how many team members there will be, maybe one, maybe five... Is it possible to get by with one field, for example "members", so as not to write many fields like "member_1", "member_2" and so on? And how then in the variant with the creation of many fields of the same type to use related_name? class Brigade(models.Model): brigadier = models.ForeignKey( 'Personal', null=True, blank=False, on_delete=models.SET_NULL, verbose_name='brigadier', related_name='brigadier' ) member_1 = models.ForeignKey( 'Personal', null=True, blank=True, on_delete=models.SET_NULL, verbose_name='member_1', related_name='brigade' ) -
Background image not loading when within <style> tags. It works fine when styled within the <div> itself. Not an incorrect filepath problem
I am unable to put a background image into the <style> tags and I don't know why it's not working. All of the following was done on my local machine. My website is also hosted on a Linode server. I have the following code, which works fine. It sets the background image in a style directly in the div within the body (via Django): <body> <div class="scroll-container" style="background-image: url('{% static 'myapp/scroll-L.jpg' %}');"> </div> </body> And when I load the page you can see the scroll image loads fine (image1 https://i.imgur.com/T75mFyl.png) However when I put the background image into the <style> tag in the <head> everything starts to go wrong: <style> .scroll-container { background-image: url("../../static/myapp/scroll-L.jpg") } </style> When I load the page you can see the scroll image doesn't load (image2 https://i.imgur.com/RCsWhE7.png) I can't use Django's {% static ... %} within the head style tags so that didn't work. It's clearly something to do with the object storage (eu-central-1.linodeobjects) but I don't know what. Why would it work when using the image in the div style and not within the style tags? I've searched around for about 2 hours trying to find a fix but I can't figure it out. The … -

correct way to redirect two views to one template with different url id Django

Django runserver crashes on chunked encoding
I am writing a Java client that posts a multipart/form-data request to a Django server. But Django logs an error (though the request continues to the view, just without the body). When Django is deployed behing Nginx it is working normally, which is why I suspect Django's runserver setup may not be able to handle it. The error is: code 400, message Bad request syntax ('23'). This 23 is part of the transfer-encoding: chunked that is being sent. I didn't find any reference that Django isn't able to understand chunked encoding so I am lost where this is going wrong. Java client, using Spring's WebClient: public void saveRecording(String token, Integer songId, String fileLocation) { var recording = new FileSystemResource(new File(fileLocation)); var data = new MultipartBodyBuilder(); data.part("songId", songId.toString(), MediaType.TEXT_PLAIN); data.part("recording", recording, MediaType.APPLICATION_OCTET_STREAM); webClient.post() .header("Authorization", token) .body(BodyInserters.fromMultipartData(data.build())) .retrieve() .toBodilessEntity() .block(); } Wireshark capture, notice the 23 after Content-Type which is part of the chunked encoding and which I believe is the reason for the error.

Unable to render a D3 chart to my web page in a Django project
I have a Django project where a form takes a file from the user (.json), processes this file, populates a post-gres database, and then at the front-end I pull some of that data back out to render a table - this works well so far. However, I also want to draw a D3 bar chart that also pulls data from my db and plots it, this is what I am currently unable to do. I have created the chart in full, and it works correctly when I render it on its own template html. Though when I attempt to draw the chart beneath my main data table (on the page I need it to appear on), I am faced with problems. The issue is, I cannot get the d3 chart to appear on my main web page, anywhere. Here is the error message: Uncaught SyntaxError: Expected property name or '}' in JSON at position 1 at JSON.parse (<anonymous>) at d3bar.js:1:19 It looks like there's an issue with the formatting if the incoming json data, or least the object that emanates from the initial json data.

How can I retrieve a value from my PostgreSQL database and print it in my html website?

My problem is whenever I try to py manage.py makemigrations I get error: django.core.exceptions.ImproperlyConfigured: AUTH_USER_MODEL refers to model 'api.UserAccount' that has not been installed I tried to delete all migrations files and reset my DB but it doesn't work. Do you have any idea what is wrong ?
