How to load static file from JavaScript in Django?
Hello so I have been trying to play an audio element in my Django app and controlling it using JavaScript. I was trying to play the audio from localhost, but I got the following errors: And I guess it's because I made a mistake in loading the audio file in my JS code. import AudioPlayer from './AudioPlayer.js'; const audioPlayer = new AudioPlayer('.audioPlayer', [ {url: '../music/rainfall.mp3', name: 'Alleviating Rainfall'}, ]); I think I did wrong on the url: part so django does not load my mp3 file and serve it from the server. So my question is, how can I load static audio file in Django from JS? I know for HTML it's {% static "[filepath]" %} but what's for JS?? Since the JS itself is a static file.. Here's my file directory: -

Django using modals for deleting a user

Purpose and use of Wagtail/Django template tags of the form {% block body_class %}template-homepage{% endblock %}
In the Wagtail docs (Your first Wagtail site) we are told to create a homepage.html template as follows: {% extends "base.html" %} {% load wagtailcore_tags %} {% block body_class %}template-homepage{% endblock %} {% block content %} {{ page.body|richtext }} {% endblock %} In the above code, what is that tag {% block body_class %}template-homepage{% endblock %} supposed to be doing? I can't find any mention of it in the text of the tutorial. The tutorial goes on to instruct us to create two more templates, blog_index_page and blog_page templates, both of which are to contain {% block body_class %} tags. Again, I can find no mention at all of those lines in the docs, let alone an explanation of how they might be used/modified. A search for "body_class" in the docs finds only the three code blocks just mentioned, and one other mention: in the version 1.2 release notes, under 'What's new — Minor features' the notation: "Simplified body_class in default homepage template." Any insight as to what I'm supposed to do with these tags? What special meaning, if any, does the tag-enclosed text have in the tutorial templates (for example, "template-homepage" in the code above)? -
Is there a page or an explanation of django testing functions?
I am looking at some tutorials on django testing from django.test import TestCase from .forms import ItemForm class TestItemForm(TestCase): def test_item_name_is_required(self): form = ItemForm({'name': ''}) self.assertFalse(form.is_valid()) self.assertIn('name', form.errors.keys()) self.assertEqual(form.errors['name'][0], 'This field is required.') I understand the importing and the class with it's parameters. I am struggling to understand the .assertXXX(). I tried looking in the documentation for django, for these functions and all I get are examples of them being used, not explanations of what they do. Then I went to GitHub to try and look under the tests folder for what the tests could potentially do and I do not fully understand their code. for example I understand that .assertEqual(<first>, <second>) compares the two parameters and checks if they are equal. I am looking for some site or some resource that can explain to me what they might potentially do, like a index or something that has similar documentation to JQuery. -
Multiple field text search in Django
I have an app "api", and a folder "models" in it. In that folder I have several ".py" files, such as "client.py", "therapist.py", "user.py" and etc. In "therapist.py" I have several classes, but I need just one class "TherapistProfile". In that class there are several fields, but I need just "name", "surname", "skills", "city" for searching. So the purpose is to search by writing a sentence. Example (of what user can write in the search bar): "Tommy davidson listening london" (and it has to be case insensitive). The words will be separated by space. Also it has to work if we miss any of the fields: "Tommy listening london" (we didn't write the surname) Also: "London listening tommy" (we are able to change the places of the words) Here is TherapistProfile class from models/therapist.py: class TherapistProfile(NonAdminProfile): user = models.OneToOneField(Therapist, on_delete=models.CASCADE, related_name='therapist_profile') skills = models.ManyToManyField(TherapistSkill, blank=True) city = models.ManyToManyField(TherapistCity, blank=True) ... PS The "name" and "surname" fields are in Therapist class (which inherits them from user.py). In TherapistProfile the field is written as "user". I kinda know the logic: I need to split the sentence into words by space and search each word in each field of each object (if you … -
Django how to limit template to only two posts

Store list of tuples django model in easy to access way
I'm creating django application for online Barber Shop booking. I came out with an algorithm that store avaliable hours. Here is exaple how it works. Let's say that barber_1 works form 8am to 4pm. We store this date in list with tuple {(8, 16)} if someone book an 1 hour apointment for 1pm it checks if it is between tuple and if it is, it creates 2 different tuples with updated hours {(8, 13), (14, 16)}, if another apointment is booked for let's say 10am, than it deletes first tuple and creates two new on it's place {(8, 10), (11, 13), (14, 16)} and so on and so on. I have a problem with "translating" my python code to the Django model. Can't find a way to store list of tuples in accesable way to be able to edit it. I read on different post that list of tuples can be stored in many to many relation but I dont think that it will be good in my case. -
Deploying Django DRF and Nuxt.js to Heroku (managing ports)
So I have deployed my Nuxt and Django to Heroku using the following buildpack. So I am running two servers in one app. So my frontend deployed successfully, however I can't setup the ports and hosts for my backend server. My frontends XHR requests are failing with 404, obviously my backend server should proxy to my frontend's "host" as /api/ route. I suppose it should be done using nginx - heroku module or somehow changing the procfiles with specifying the ports and hosts correctly. I would be more than glad if you could help me to clarify the setup structure. my Procfile.web django: gunicorn mydjango.wsgi:application --bind $HOST:$DJANGO_PORT node: cd frontend && yarn start -

Form validation in function views
Is there any difference between the 2 parts of code? def test(request): if request.method == 'POST': form = TestForm(request.POST) if form.is_valid(): form.save() title = form.cleaned_data.get('title') #<<-- print(title) return redirect('blog-home') else: form = TestForm() return render(request, 'blog/test.html', {'form': form}) def test(request): if request.method == 'POST': form = TestForm(request.POST) if form.is_valid(): form.save() title = request.POST.get('title') # <<-- print(title) return redirect('blog-home') else: form = TestForm() return render(request, 'blog/test.html', {'form': form}) Since both cases is part of form.is_valid() condition I believe it should be same right? -
