GeneratedField() ValueError("Cannot force an update in save() with no primary key.")
In my Employee model, I defined a field called "full_name" declared as a models.GeneratedField like so: class Employee(models.Model): first_name = models.CharField(max_length=100) mid_name = models.CharField('Middle name', max_length=75) last_name = models.CharField(max_length=75) full_name = models.GeneratedField( expression=Concat( "last_name", Value(", "), "first_name", Value(" "), "mid_name" ), output_field=models.CharField(max_length=250), db_persist=True, ) created = models.DateTimeField(auto_now_add=True) updated = models.DateTimeField(auto_now=True) user = models.ForeignKey(settings.AUTH_USER_MODEL, on_delete=models.SET(get_sentinel_user)) However, when I tried to save a record in the admin page, I got ValueError("Cannot force an update in save() with no primary key."). To find out what causes the problem, I tried the following: Commented out the user field, and the system worked just fine. Re-instated back the user field, but changed to on_delete=models.SET_NULL, null=True, blank=True. Runserver and tried adding records in the admin page. Here, I observed that: If I left the user field blank, the system worked just fine. If I set the field with an existing user, this is where the system error occured. Anyone else encountered this problem? How did you fix this? Or is this some kind of a bug? django 5.0 -
Seeking Recommendations: Best Communities for Python and Django Developers?
Could you please recommend some great communities across different platforms that are largely beneficial for Python and Django developers? As a beginner Python developer, I wish to connect with the larger Python and Django communities to learn and stay updated with the latest trends. Any online forums, Discord servers, social media groups, or any other platform, I'm interested in discovering places where developers gather to discuss, share resources, and learn from each other. I've tried using Google to discover communities for Python and Django developers, but the results haven't been quite satisfying. Even personal recommendations mean a lot to me. Thank you in advance for sharing! -
MultipleObjectsReturned at /contact-agent/ get() returned more than one Property -- it returned 2
So I am trying to build a website using Django where users can visit a property-detail page then contact the property's agent. Users need to fill out a form which will then be sent to the agent via email. My email is working fine but since property-detail view is a class-based view and the contact_agent view is a function based view they are different views. So I can't seem to get the property's agent dynamically to get the agent's email to send him the email.

The button in the template file does the work of the previous button
The seller should be able to choose one of the offers by entering the product page and sell the product to him, and then no one else can make an offer on the price of the product. On the product page, the winner should be notified that you have won. Now the button comes and there is no error. But the button does the work of the button before it, which is to save. That is, you click on the button and then the product will be added to the saved list.

how to handle pagination of a dynamic table in django rest framework
I have a table which stores user's favorites: When user X marked an item Y as his favourites, a new record will be added to this table: id user_id item_id is_active ... X Y true When user X canceled his favorite on item Y, the is_active field will be set to false id user_id item_id is_active ... X Y false When user X re-favorite item Y, the is_active field will be set to true. Actually this is done by django create_or_update() method. So the table is like: id user_id item_id is_active 1 1001 201 true 2 1001 202 true 3 1001 203 true 4 1001 204 true 5 1001 205 true 6 1001 206 false 7 1002 201 true 8 1002 202 true 9 1003 201 true When user 1001 requests his favorites list, the queryset will be: queryset = Favorite.Objects.filter(user=1001, is_active=true) the response will be (I only list the record id): [1, 2, 3, 4, 5] if the pagination size is set to 2, user 1001 will get a response: { next: ...?page=2, previous: null, data:[1, 2] } but if user 1001 canceled his favorite on item 202 now, then, when he requests his favorites list of page 2, … -

heroku migrate: django.db.utils.OperationalError: connection to server failed
I am a student learning on full-stack web development. I am very new to coding and would need help with following. I am trying to deploy my Django app to Heroku. Previously was using sqlite3 - then I did migration to postgre. Now I am trying to run the code heroku run python manage.py migrate but I am having error or django.db.utils.OperationError: connection to server, port 5433 failed. I went to pgadmin4, looked at properties of my Postgre server and port is 5433 - so I changed to 5433. I believed it's due to my installation of previous version of postgre which took up default 5432 port. Anyway, I have no issues when i py manage.py runserver. Everything works properly. So I did heroku create - after that, there's application error when i try to access the website. Not sure if it's supposed to be error at this point of stage. Next step should be heroku run python manage.py migrate where the error occurs. Below is my code for settings.py: """ Django settings for recipe_project project.

django-cors-headers not working when proxy set in react side
I have a very big and completely unusual problem in django cors headers. I searched a lot but did not get any results. I have a full stack Django and React project. I determined the back end of the allowed origins. When a React project without a proxy (the proxy feature in the package.json file) makes a request to the backend, if that domain is not allowed, SOP stops it, but when it is used with a proxy, it makes a request to the backend even if that domain is not allowed. It can read and display data. It means that another React project on another domain can request and read data with a proxy. It seems to bypass the SOP. On the backend side, I use the django-cors-headers==3.8.0 package and I read all its documentation, I made all the settings correctly, but I don't know why this bug appeared, please help me. -
Cant figure out where I made a mistake in the code, would appreciate help (Django unittest referencing class in test method)
I have the tests and I have a separate file with a class that keeps all the methods and what not that are used in the tests. This is done to follow DRY principle (and also because my reviewer told me to and I am to comply, lol). However, in the recent feedback I got from the reviewer I got an assignment I cannot seem to make and that is moving part of the code in that class with common inputs from a separate method into setUpTestData(cls) method (where most of the data are). I used to have 2 more methods in the code below: one was something like def one_note(cls): and another one was like def note_list(cls) and under those names the code that is now located under if cls.a==1 and if cls.a==2 was stored. The reason I cannot simply declare all the functions in the code is I need a tool to make it possible to only choose one option as they are mutually exclusive in my tests. I was thinking to add if condition with a value here in the class with the stored information and then use the value I need in test methods. But for … -

It is working fine, when only one product is in cart, otherwise I need to refresh the page. cart.html <div class="quantity__row"> <form action="{% url 'remove_cart' %}" method="post" id="removeCartID"> {% csrf_token %} {{ item.update_quantity_form.quantity }} {{ item.update_quantity_form.update }} <input type="hidden" name="product_id" value="{{ item.product.id }}" id="productRemoveID"> <input type="submit" value="-" class="quantity__number-minus"> </form> <input type="number" min="1" value={{ item.quantity }} readonly="readonly" class="quantity__input" id="quantityID"/> <form action="{% url 'add_cart' %}" method="post" id="addCartID"> {% csrf_token %} {{ item.update_quantity_form.quantity }} {{ item.update_quantity_form.update }} <input type="hidden" name="product_id" value="{{ item.product.id }}" id="productAddCartID"> <input type="submit" value="+" class="quantity__number-plus"> </form> </div> views.py def add_to_cart(request): if request.method == 'POST': product_id = request.POST.get('product_id') product = Product.objects.get(id=int(product_id)-1) cart = Cart(request) cart.add(product=product) cart_quantity = cart.get_total_len() return JsonResponse({'success': True, 'cart_quantity': cart_quantity}) def cart_remove(request): if request.method == 'POST': product_id = request.POST.get('product_id') product = Product.objects.get(id=int(product_id)) cart = Cart(request) cart.remove(product) cart_quantity = cart.get_total_len() return JsonResponse({'success': True, 'cart_quantity': cart_quantity}) scripts.js $(function() { $('#addCartID').on('submit', function(e){ e.preventDefault(); $.ajax({ url: '{% … -

Django file creation error. Why do I get an attribute error: the 'bytes' object does not have the '_committed' attribute?
Actually, the error occurs when an entry in the database is trying to be created. It is not clear why the saved object is not perceived by the server as a File type, but if you print the type of this object, then it is a File, but the error says something else. The error occurs only on the server, everything works if I run it on my machine. The server is hosted on pythonanywhere.com.

list index out of range in Comparing two prices
I want to compare the received price with the previous prices and send a message if it was lower, but it shows this error to receive the first entry. I also tried to try and while. It didn't give the expected result. If I remove this condition and enter a number and apply this condition again. The code works correctly.

how to transfer file from server to client via json
I am trying to transfer the processed pdf file on the server to the client side so that the user can download it. Here is my code on the server - @app.task def pdf_protect(file_path, file_id, password): with open(file_path, 'rb') as file: reader = PdfReader(BytesIO(file.read())) writer = PdfWriter() writer.append_pages_from_reader(reader) writer.encrypt(password) output = io.BytesIO() writer.write(output) output.seek(0) send_notification.delay({'filename': 'result.pdf', 'content': base64.b64encode(output.read()).decode('utf-8')}, file_id) In this code I use the pypdf library and encrypt the pdf with the given password. After that, I try to convert the processed pdf file into bytes and pack it into json in order to send it to the client side via a websocket connection. On the client side I have the following code - chatSocket.onmessage = function (e) { const data = JSON.parse(e.data); var blob = new Blob([data.message.content], {type: "application/pdf"}); console.log(data.message.content) downloadLink.href = URL.createObjectURL(blob); downloadLink.download = data.message.filename; chatSocket.close(); }; In this code I get the data from the json and make a link to download the file. But after downloading and opening the pdf file, the error "Failed to load the PDF document." or just a blank page. But what happens when I send a response to the client via FileResponse and then use the same method to make … -
Django uploading PDF and mailing it
So I want to code a website using Django where anyone can apply to become agents for the company. To apply they fill out a form where they upload their resume/CV which is then mailed to the HR. Now my code doesn't seem to take the pdf since it returns none after hitting submit. Also the mail isn't being sent. How can I fix this? Thanks in advance!
