Django readonly_fields not showing data
My Orders model has 'rate' and 'total_amount' field. I had to derive rate from different model so i created 'unit_rate'. Same way i wanted my 'total_amount' fields should be multiplication of 'quantity' and 'unit_rate' which i tried by doing 'total_pay'. You can see my code for the same below. class OrderAdmin(admin.ModelAdmin): def unit_rate(self,obj): self.rate = Product.objects.get(pk=obj.order_id) return self.rate.price def total_pay(self,obj): self.rate = Product.objects.get(pk=obj.order_id) self.total_amount = self.rate.price * obj.quantity return self.total_amount list_display = ('order_id', 'order_item', 'order_status', 'delivery_address', 'customer', 'quantity','unit_rate','total_pay') readonly_fields = ('total_pay','unite_rate') admin.site.register(Orders,OrderAdmin) As 'total_pay' and 'unit_rate' are obtained from other columns, admin doesn't need to enter them. That's why i kept them on readonly_fields'. Problem is whenever is create order through admin interface, 'total_pay' and 'unit_rate' does not shows up in admin. It just shows dash like this -. Doing this since a while. I could really use your help.thanks -
Django view with simple GET method results in TypeError
Using a very simplistic subclass of django.views.View I only get a TypeError with »__init__() takes 1 positional argument but 2 were given« as message. urls.py is: from myapp import views from django.urls import path urlpatterns = [ path('webhook/', views.Webhook, name='myapp-webhook'), ] views.py: from django.http import HttpResponse, HttpResponseForbidden from django.views import View class Webhook(View): def get(self, request, *args, **kwargs): """We don't provide GET access here.""" # return 403 (Forbidden) return HttpResponseForbidden() def post(self, request, *args, **kwargs): # return 200 (OK) return HttpResponse() tests.py: from django.test import TestCase class WebhookTests(TestCase): def test_get_method_is_forbidden(self): response = self.client.get('/webhook') self.assertEqual(response.status_code, 403) Now, either accessing /webhook in a browser or running ./manage.py test results in: Internal Server Error: /webhook/ Traceback (most recent call last): [...] TypeError: __init__() takes 1 positional argument but 2 were given I'm surely missing something here.

Django DB design - Book specific unique URLs with unique_together
I have two models with one to many relationship. A Book has many Chapters. Both the models have a slug field. For Book the slug column is UNIQUE. For Chapter the book_id and slug are UNIQUE together. The Chapter model also has a field order. And book_id and order are UNIQUE together. This way, I can generate unique URLs for books automatically and allow duplicate slugs for different books. Current models.py: class Book(models.Model): # other fields slug = models.SlugField(max_length=80) def save(self, *args, **kwargs): if not self.pk: self.slug = unique_slug(self.title) return super(Book, self).save(*args, **kwargs) class Chapter(models.Model): #other fields book = models.ForeignKey(Book, on_delete=models.CASCADE, related_name='chapters') slug = models.SlugField(max_length=80) order = models.IntegerField(null=True) class Meta: constraints = [ models.UniqueConstraint(fields=['book_id', 'order'], name='unique_order'), models.UniqueConstraint(fields=['book_id', 'slug'], name='unique_slug')] ordering = ['order'] The downside here is, in my chapter views I have to query the book first and get the chapter slug with the matching book_id. While previously with just the chapter slug UNIQUE, I was just querying the chapter table alone. My goal is to have URLs like this book/rndmstrng-alice-in-the-wonderland/chapter/down-the-rabbit-hole book/rndmstrng-some-other-book/chapter/down-the-rabbit-hole Is there any issue in this design? Are too many UNIQUE constraints bad? Is there a better way to implement this? -
How to send data from custom.py to html - Django
Concept that I'm trying to achieve: A web application with speech enabled that displays what the user says, on UI. Example: If the user says "Hello there!", "Hello there!" should be displayed on the UI. What I have: Files that I have in my app: speech.py (has a variable(displayOnUI) that stores what the user says) speech.html (where I want to display what the user says) Note: speech.py repeatedly keeps listening to user and keeps storing what the user says in a variable(displayOnUI). What I tried: I tried passing the value of the variable displayOnUI which is in speech.py to view.py and then passing it to speech.html using context. speech.py displayOnUI= "Please say something.." def SpeechRecognition(): while 1: try: with sr.Microphone() as source: r.adjust_for_ambient_noise(source, duration=1) audioReceived = r.record(source, duration=3) displayOnUI= r.recognize_google(audioReceived) view.py from SpeechApp.speech import displayOnUI def speech(request): data = displayOnUI return render(request, "speech.html", {"data": data}) speech.html <div> <h3>This is what I heard: {{data}} <h3/> </div> Problem that I'm facing I'm able to display the initial value that is present in displayOnUI (that is "Please say something..") on UI, however I'm not able to display the updated value(user's command) of displayUI in speech.html.

Django JavaScript fpr bootstrap grid does not work

Here's the problem: I've implemented a custom manager for a model with just one custom query named get_by_tag and it's working fine if I use it this way: UsageStatistic.objects.get_by_tag('some-tag-name').filter(user=user_id) But when I change the order of queries, in this way: UsageStatistic.objects.filter(user=user_id).get_by_tag('some-tag-name') it doesn't work! and raise this error: AttributeError: 'QuerySet' object has no attribute 'get_by_tag' Am I missing something?! P.S: FYI the custom manager is somethin like this: class MyCustomManager(models.Manager): def get_by_tag(self, tag_name): posts = Post.objects.filter(tags__pk=tag_name) return super().get_queryset().filter(post__pk__in=posts) -

Django forms are not being processed with POST request
I have written the most basic Django application to understand forms as below. When I enter the required data into the fields and press Submit, the code after "if request.method == 'POST'" is ignored. I am redirected to the appropriate page and an entry with the first name "John" and last name "Smith" is created in my database. As you can see in the code below, this object should only be created if the request method is not POST. I know that I have set the request method to POST because that is what is shown on my CMD so what is happening?? Here is my template 'index.html': <!DOCTYPE html> <html> <head> <title>Welcome to the site</title> </head> <body> <form action="thanks/" method='POST'> {% csrf_token %} {{ form.as_p }} <input type="submit" vlaue="Submit"> </form> </body> </html> Here is my views.py file: from django.shortcuts import render from django.http import HttpResponseRedirect from .forms import NewObjectForm from .models import Object # Create your views here. def index(request): if request.method == 'POST': form=NewObjectForm(request.POST) if form.is_valid(): first_name=form.cleaned_data['first_name'] last_name=form.cleaned_data['last_name'] a=Object.create(first_name=first_name,last_name=last_name) a.save() return HttpResponseRedirect('/thanks/') else: new=Object.create(first_name="Not",last_name="Valid") new.save() else: #Code which is run if the request.method is not equal to 'POST' form=NewObjectForm() newer=Object.objects.create(first_name="John",last_name="Smith") newer.save() return render(request,'formapp/index.html',{'form':form}) def end(request): return render(request,'formapp/thanks.html') -
How to hide html button if queryset doesn't have next blog post in Django?
I would like to hide the Next button in my blog if there is no next blog post available. Is there some kind of built-in method to check has_next has_previous or do I need to create some logic in my view and extend the template with let's say {% if Foo %} show button {% endif %} ? views.py def render_post(request, id): category_count = get_category_count() most_recent = Post.objects.order_by('-timestamp')[:3] post = get_object_or_404(Post, id=id) next_post_id = int(id) + 1 previous_post_id = int(id) - 1 PostView.objects.get(post=post) context = { 'post': post, 'id': id, 'next_post_id': next_post_id, 'previous_post_id': previous_post_id, 'most_recent': most_recent, 'category_count': category_count, } return render(request, 'post.html', context) html <div id="button-wrapper"> <button class="buttons" type="submit"><a href="/post/{{previous_post_id}}">Previous</a></button> <button class="buttons" type="submit"><a href="/post/{{next_post_id}}">Next</a></button> </div>
