Reverse for 'author_details' with arguments '('',)' not found. 1 pattern(s) tried: ['author_details/(?P<auth_id>[^/]+)/\\Z']
I'm new to python and currently developing a practice app similar to Goodreads just to test and challenge myself. I have reached the part where I created three pages one with a simple list of books with a link to book details where there is a link to the author profile. The link between the book title link and the book details page works--but when I click on the author link on the book details page it gives me an error Reverse for 'author_details' with arguments '('',)' not found. 1 patern(s) tried: ['author_details/(?P<auth_id>[^/]+)/\\Z'] Here is my code. views.py from django.shortcuts import render from .models import Book from .models import BookAuthor from .models import BookGenre def authors_database(request): authors_database = BookAuthor.objects.all() return render(request,'authors_database.html',{ 'authors_database':authors_database }) def book_details(request,book_id): book_details = Book.objects.get(pk=book_id) return render(request,'book_details.html',{ 'book_details':book_details }) def author_details(self,auth_id): author_details = BookAuthor.objects.get(pk=auth_id) return render(request,'author_details.html',{ 'author_details':author_details }) def index(request): return render(request,'index.html',{ }) def discover_books_list(request): discover_books_list = Book.objects.all() return render(request,'discover_books_list.html',{ 'discover_books_list':discover_books_list }) book_details.html {% extends 'layout.html' %} {% block body %} <div class="container"> <div class="row"> <div class="col-md-4"> {% if book_details.book_cover_image %} <img src="{{book_details.book_cover_image.url}}" height="480" width="300" class="img-responsive"> {% endif %}<br> </div> <div class="col-md-8"> <h3>{{book_details}}</h3> <hr> <strong>By: </strong><a href="{% url 'author_details' auth.id %}">{{book_details.book_author}}</a> <br> <strong>Publication date:</strong> {{book_details.book_publication_date}}<br> <strong>In:</strong> {% … -
Serving sveltekit dev under django
I am building a project and I am trying to use sveltekit as front-end and Django as back-end. I am using gunicorn to serve Django and nginx as web-server that proxies to gunicorn. I want to serve sveltekit dev server under Django so that I don't have to add CORS and tweak settings.py to use different settings for production and development. Instead of developing front-end under http://localhost:3000, I want to access it like http://some-project.dev/app which points to Django. Is this possible? -
Contact form on a users personal site that posts to my Django DB?
I am wondering if it is possible to provide users of my django website a copyable HTML form element to put on their own personal website that actually POSTs to my Django database? The idea is to allow a User of my Django app to copy and paste an HTML Contact form into their own personal website with fields such as name, phone, email, notes which will all be fields of a model in my Django app. Basically when visitors of their website fill out the contact form I would like to post it to my Postgres DB in a model such as.. class Lead(models.Model): user = This would be the user on my Django app name... phone... email... notes... Is something that is possible or even safe to do? It would really be a big part of my project to allow for this lead collection. -

How to insert data from html form into MySQL database using python django
I have created an html form in add_appointment.html and have created database "hospital", table "appointment" in MySQL. I able to view values that I inserted into my database on another html page called view_appointment.html but I do not know how to take html form input from the "add_appointment.html" file and insert it into MySQL database.

How to pass data of all input fields from one page to another using button in python django
I have a form on index.html and I want to pass data of all input fields of index.html to demo.html by using a button.

Django auto submits form when page loads
I have this form inside my view if request.method == 'POST': button_form = TicketSolved(request.POST) if button_form.is_valid(): return redirect('https://google.com') I removed the content and added a redirect to google to test if its still broke. When the page loads, i automaticly get redirected to google.com, so the form will be submitted automaticly which is bad. It is a normal form in the HTML Template <form method="POST"> {% csrf_token %} {{ button_form }} <button type="submit"> How can I stop the automatic submission of the form when the page loads? Because the form will be actually a button. When someone clicks on the button (the form is valid), following code will be executet: obj.reopened_counter += 1 # if obj.reopened_counter > 5: # obj.ticket_waiting = True # obj.ticket_solved = False # # if obj.ticket_waiting == False and obj.ticket_solved == True: # obj.ticket_waiting = True # obj.ticket_solved = False # else: # obj.ticket_waiting = False # obj.ticket_solved = True # obj.save() So everytime someone clicks the button in the form, the counter will go +1. But even if the user just reloads the page, the counter will go up +1 because of this auto-submit-when-loading-view problem. -

Django - export one txt file per row to local drive
I'm stuck with this as I can't find any relevant tutorials online. I would like to export all of the data in a model to the txt file format {actually xml but I think that's besides the point} where each row in the model is a seperate file and saved to a relative local path to the database with the folder and filenames for each being derived from two fields in the model I also need these to replace any existing files of the same name Where would I start?

django-import-export, importing ManyToMany from XLSX
For my current project I need to import data from excelsheets format .xlsx to the django-admin. I'm struggling with the many2many relations that I have in my models. The importing feature just doesn't recognize the many2many fields and imports only the remaining fields (normal and foreignkey). Same goes for exporting, all fields except the many2many get exported into a excelsheet, although I dont need this feature, just tested it. For better understanding the code snippets from my models.py, admin.py, resources.py and widgets.py. I tried the default many2many widget -> in the TeacherResource in resources.py and I also tired overriding the default m2m widget -> StudyfieldWidget in widgets.py models.py class Translation(models.Model): de = models.TextField(unique=True) en = models.TextField(unique=True) def __str__(self): return self.de class Studyfield(models.Model): degree = models.CharField(max_length=50) title = models.ForeignKey("Translation", on_delete=models.CASCADE, related_name="+") def __str__(self): return self.title class Course(models.Model): number = models.CharField(max_length=50) title = models.ForeignKey("Translation", on_delete=models.CASCADE, related_name="+") studyfields = models.ManyToManyField("Studyfield", related_name="course", blank=True) def __str__(self): return self.title class Teacher(models.Model): name = models.CharField(max_length=50, blank=True) studyfields = models.ManyToManyField("Studyfield", related_name="teacher", blank=True) courses = models.ManyToManyField("Course", related_name="teacher", blank=True) def __str__(self): return self.name admin.py @admin.register(Translation) class TranslationAdmin(ImportExportModelAdmin): resource_class = TranslationResource ordering = ('id',) formats = [base_formats.XLSX] @admin.register(Studyfield) class StudyfieldAdmin(ImportExportModelAdmin): resource_class = StudyfieldResource ordering = ('id',) formats = [base_formats.XLSX] @admin.register(Course) class … -
Django Many to Many - polymorphic
In a Django application, I have three models: Service Product AppliedTax I want to create a many-to-many relationship between Service and AppliedTax and between Product and AppliedTax. Normally I would have an intermediate model (i.e. AppliedTaxTaxable) with three fields (applied_tax_id, taxable_type and taxable_id) and taxable_type + taxable_id would be a composite foreign key for each related model with taxable_type having as value the name of the related model (Service or Product in my case) and the taxable_id field the id of the related record of the respective model. I understand how to make it work with raw queries, but Is there a "Django" way to do that with a ManyToMany relationship? So far I had no luck with that. I don't have much experience with Django, but I hope there is a way to do that without using raw queries. Help :) -

How to set a timer inside the get request of an APIView?
I am trying to build a timer inside a get method in a DRF View. I have created the timer method inside the GameViewController class and what I am trying to achieve is that a every minute (5 times in a row) a resource object is shown to the user through the get request and a game round object is created. My View works at the moment, however the timer doesn't seem to be doing anything. I know this isn't exactly how things are done in django but this is how I need to do it for my game API for game logic purposes. How can I make the timer work? Do I need to use something like request.time or such? Thanks in advance. views.py class GameViewController: def timer(self): """Start a new timer as soon as a gameround has been started/created""" start_time = datetime.now() elapsed_time = None if start_time is not None: elapsed_time = time.perf_counter() """Stop the timer, and return the elapsed time""" if start_time is None: elapsed_time = time.perf_counter() - start_time return elapsed_time ... class GameView(APIView): def get(self, request, *args, **kwargs): ... round_number = gametype.rounds time = controller.timer() while round_number != 0: if time >= 1: random_resource = Resource.objects.all().order_by('?').first() … -
'str' object has no attribute '_encode_json'
I've been writing a test with RequestFactory to test one of my views, with the following code: class ViewTestCase(TestCase): @classmethod def setUp(self): self.factory = RequestFactory self.user = User.objects.create_user( first_name='tester', username='test1', password='123', email='testuser@something.com' ) def test_room_creation(self): payload = {"titlePlanning": "Test1","styleCards": "Fibonnaci","deck": ["1","2","3"]} request = self.factory.post('/room', payload) request.user = self.user response = BeginRoom.as_view()(request) self.assertEqual(response.status_code, 200) This is the data that I need to send to use POST: class BeginRoom(APIView): permissions_classes = (IsAuthenticated,) def post(self, request, format=None): data= self.request.data user = request.user name = data['titlePlanning'].strip() styleCards = data['styleCards'] cards = data['deck'] My problem is that whenever I run my tests I get the following error: data = self._encode_json({} if data is None else data, content_type) AttributeError: 'str' object has no attribute '_encode_json' What should I do? I'm lost from here and can't find anything related. Any help is appreciated!
