Field 'id' expected a number but got 'add'
I'm working on a Django project where I have an API endpoint for adding PC parts, and I'm encountering an issue when trying to access the URL /parts/add. I'm getting the following error: ValueError: Field 'id' expected a number but got 'add'. This error seems to be related to my Django model's primary key field, which is an AutoField called 'id.' I'm not explicitly providing an 'id' when adding a new PC part, and I expect Django to generate it automatically. here is my model: from django.db import models # Create your models here. class PCparts(models.Model): id = models.AutoField( primary_key=True) name = models.CharField(max_length=128) type = models.CharField(max_length=50) price = models.DecimalField(max_digits=10, decimal_places=2) release_date = models.IntegerField() # Unix epoch timestamp core_clock = models.DecimalField(max_digits=5, decimal_places=2) boost_clock = models.DecimalField( max_digits=5, decimal_places=2, null=True, blank=True) clock_unit = models.CharField(max_length=5) TDP = models.IntegerField(default=0.0) part_no = models.CharField(max_length=20) class Meta: ordering = ['-price'] def __str__(self) -> str: return self.name here is my view from rest_framework import status from django.shortcuts import render from django.views.decorators.csrf import csrf_exempt from django.http import JsonResponse from django.db.models import Avg from .models import PCparts from .serializers import partSerializer # Import the serializer class from django.views.decorators.csrf import csrf_exempt from django.views.decorators.http import require_http_methods from django.db.utils import IntegrityError # Create your … -
Trouble Sending POST Data for Google Calendar Scheduling in Django: Ajax Newbie
I'm building an app to schedule events on Google Calendar using Django, and I'm encountering an issue with sending data via a POST request to a Django view. Here's my Django view code for CreateEventFunc: from django.http import JsonResponse from django.views.decorators.csrf import csrf_exempt import json @csrf_exempt def CreateEventFunc(request): # For debugging purposes, write data to a file with open('output.txt', 'w') as file: file.write("CreateEventFunc\n") if request.method == 'POST': data = json.loads(request.body.decode('utf-8')) therapist_id = data['therapist_id'] start_time = data['start_time'] end_time = data['end_time'] # Create the event using your utility function (e.g., create_event) # Replace this with your actual implementation created_event = create_event(therapist_id, 'Appointment', start_time, end_time) # Return a response (you can customize this based on your needs) response_data = {'message': 'Event created successfully', 'event_id': created_event['id']} return JsonResponse(response_data) On the frontend, I have a JavaScript function scheduleMeeting that sends a POST request to this view when a meeting is scheduled: <script> function scheduleMeeting(startTime, endTime, therapistId) { if(confirm("Do you want to schedule a meeting from " + startTime + " to " + endTime + "?")) { // Create a data object to send with the POST request var eventData = { 'start_time': startTime, 'end_time': endTime, 'therapist_id': therapistId, }; // Send a POST request to … -
How can I get a django form value and display it back to the user before the form is submitted?
I have done some research...and found a suggestion to create a function on a form to get a field value...get form value I tried this and for some reason I can't get it to work. I've used the clean function on the form as part of the submit process and that works great. The difference here is that I'm essentially trying to inspect the field values well before the form gets submitted. I want the user to click a button and see the values that have been populated in the "approvers" field in this case. I've got the button working...but can't seem to get the "approvers" value to populate. It just shows []. I defined the function on my form... def get_invitee_name(self): invitees = self.cleaned_data.get('approvers') return invitees But when I try to call the function in my template as {{ invitees }} ...nothing shows up. Do I need to define this as a context variable as well? Do I have to do this using Javascript instead or is there a way to do this with pure Django/Python? I'm using a ModelForm if it matters. Thanks in advance for any thoughts. -
How can I prevent django from claiming localhost port 80 via httpd after I've removed my project?
My problem is that my localhost port 80 is taken by an auto-reloading Django proc that I no longer need and I cannot kill the Django proc(s) because they auto-reload upon being killed. I did Django a while ago for an interview assignment so it's not trivial to get back into that and manage it that way. Is there a way simply on macos to prevent this process from coming back? I've tried using launchctl but it's unclear which item would be facilitating the auto-reloading. I have 2 mystery django process that get auto-reloaded whenever I kill it with sudo kill {PID}. i.e. I kill the procs, I check to make sure port 80 is not being used anymore with sudo lsof -i :80, and it shows 2 new procs that have auto-reloaded. I am hoping to do anything at all so that when I run sudo lsof -i :80 I get no results. -

for loop in django templates not working as expected
I am creating a django app and am iterating through the images list. I've been at it for hours to no avail. I looked everywhere for help and still couldn't fix it. I successfully got the POST request with ajax and when I print it to the console the images sources are there in the list. But, upon iterating it in the django templates, it doesn't show up.

How to substitute a value into a form field from a database
I have related models; when they are saved, some data is saved in the first model, others in the second. Now I'm trying to update the data so that when a button is pressed, the data from the two models is updated since the fields in the form 'client_name' and 'phones' are not connected to anything, I partially achieved this, they are updated and saved, but when the form is opened, the fields 'client_name', 'phones', I need to somehow substitute previously saved values into these fields so that they can be edited in the field. models.py from django.db import models from django.contrib.auth.models import User # Create your models here. class Person(models.Model): client_name = models.CharField(max_length=100, verbose_name='Фио клиента') def __str__(self): return self.client_name class Meta: verbose_name = 'Клиент' verbose_name_plural = 'Клиенты' class Phone(models.Model): phone = models.CharField(max_length=50, verbose_name='Телефон') contact = models.ForeignKey(Person, on_delete=models.CASCADE, related_name='phones', verbose_name='Контакт', null=True) def __str__(self): return self.phone class Meta: verbose_name = 'Телефон' verbose_name_plural = 'Телефоны' class Orders(models.Model): # Основная база данных objects = None author = models.ForeignKey(User, on_delete=models.SET_NULL, null=True, verbose_name='Принял', blank=True) date_of_creation = models.DateTimeField(auto_now=True, verbose_name='Дата создания') execution_date = models.DateField(verbose_name='Дата исполнения') address = models.CharField(max_length=200, verbose_name='Адрес') service = models.CharField(max_length=100, verbose_name='Услуга') master = models.ForeignKey(User, on_delete=models.SET_NULL, related_name='master', null=True, verbose_name='Мастер', blank=True) client = models.ForeignKey(Phone, on_delete=models.SET_NULL, related_name='client', null=True, … -
Move DB cursor id after manual insert
I'm facing a case where I have to manually insert data from old DB into a new one. The new one is a DB that'll be used by a Django application. For that I have CSV file or whatever that I iterate over, and the thing is that I also use the id from this file, because I need to keep it. For instance I do : from django.db import connections cursor = connections["default"].cursor() cursor.execute("INSERT INTO my_table (id, name) VALUES (3, 'test')") If I use such ID (3), the next time I'll want to insert data through my django application, it'll create a record with ID 1, then ID 2, then I'll have an error because it'll try to create data for ID 3. How can I make it skip existing ID ? Thanks in advance ! -

why is Django not correctly routing my urls?
I am trying to put together a simple website with django. I have my routes defined and they work provided that if i want to go to home i have to localhost/home/home rather than just it being localhost/home. It is the same for my about page. localhost/home/about. If its of any help when i try to go to localhost/home or about django says the page cannot not be found. essentially a 404 error. This what Django spits out at me. For the life of me I cannot figure out why i have 4 routes when i should only have 3. Admin, Home and About. It may also be worth mentioning that if i route to localhost/about/home i will get the home page and if i route to home/home i also get the homepage, same as about, i can route to localhost/about/about and get the about page. Using the URLconf defined in bbsite.urls, Django tried these URL patterns, in this order: admin/ about/ home/ home/ [name='home'] home/ about/ [name='about'] The current path, home/, didn’t match any of these. -
Django ManyToManyField with model matching the custom through table
I have a situation similar to the Membership example from the Django documentation (https://docs.djangoproject.com/en/4.2/topics/db/models/#extra-fields-on-many-to-many-relationships). class Person(models.Model): name = models.CharField(max_length=128) class Group(models.Model): name = models.CharField(max_length=128) persons = models.ManyToManyField(Person, through="Membership") class Membership(models.Model): person = models.ForeignKey(Person, on_delete=models.CASCADE) group = models.ForeignKey(Group, on_delete=models.CASCADE) date_joined = models.DateField() invite_reason = models.CharField(max_length=64) While this works fine to get all Persons of a Group via g1.persons I would like to get all Memberships. Conceptually something like the following: class Group(models.Model): name = models.CharField(max_length=128) members = models.ManyToManyField(Membership, through="Membership") Except that this doesn't work because obviously Membership has no foreign key for itself. Is there a way to set up what I want (i.e. a convenience access to members via g1.members)? Or is the only solution to manually go through Membership.objects.filter(group=g1.pk)? -

Open layers and django
I'm new to django and open layers but I tried to create a project using both. I search the internet and found a way to make them both work with webpack but I didn't like that so much, because of 2 things, the first is the bundling process and the second is after importing the bundled file debugging wasn't that clear. I was thinking maybe there is a way to work it out without using webpack? I tried including the node_modules/ol/dist/ol.js but didn't work for me. also, I thought maybe including all node_modules in the STATICFILES_DIRS but didn't work as well, i needed later to include each file staticly. Is there a solution to this or am I bounded to work with webpacking? Thank you! -

How to Integrate a Standalone Django Live Chat App into Main Website Views?
I'm currently learning Django and have an existing website built in HTML, CSS, JS with a Java Spring backend. I am in the process of migrating it to Django. I've successfully migrated the site and now want to add a new feature: live chat groups between users. I have implemented the live chat functionality as a standalone Django app using Django Channels and Redis, following multiple tutorials. The chat app works as expected when isolated. The issue I'm facing is how to integrate this chat functionality into the main views of my existing website. Specifically, I want the chat to appear in a small window at the bottom right corner of the screen, similar to how chat features work on Facebook or other social media sites. I tried using Django's {% include ... %} tag to include the chat functionality in base.html, thinking it would behave similarly to other globally-included elements like the navigation bar. However, this approach doesn't seem to work, and there appears to be some form of communication issue between the two apps. Here is a Gist containing my project structure, base.html, room.html, and index.html for context. -

Unable to write data to AWS RDS PostgreSQL database?
In my Django application, I'm utilizing AWS RDS PostgreSQL as my database backend. I've encountered an issue when attempting to send a POST request to store data in the database. After a period of loading, I receive a '502 Bad Gateway' error. Interestingly, I can successfully read data from the database. I also have a mobile app and a separate front-end application developed in Vue.js. When making POST requests from the mobile app, all operations work flawlessly, except for the one related to OTP, which also gives a '502' error. Other CRUD operations from the app are functioning as expected. In addition, reading and writing data works properly from the Django admin panel and the dashboard, both of which are built in Django. Within the front-end application, I can write data successfully, but I encounter a '502' error when attempting to write. This issue specifically occurs when I add CNAME of Application Load Balancer's DNS point to the domain. However, if I use an IP address in the A record to point to the domain, everything functions as expected. What could be the source of this issue and how can it be resolved? -

In HTMX making an image clickable to delete itself (issue with created URL interference)
I have a page that under this URL http://localhost:8000/dashboard/myobjects/ shows me the products that I have. For each product I have a button that takes me to a page where I can change the pictures (deleting them or upload them) It takes me to this URL http://localhost:8000/dashboard/changepictures/5/built/ where 5 is the row number of the products table and built is a field header that defines the category. So far so good. Then I have this HTMX snippet that would delete the picture upon clicking: <div class="grid-wrapper"> {% for x in all_pictures_of_a_property %} <div class="grid-item"> {% if x.images %} <img src='{{x.images.url}}' width="200" height="100" name="pictures" hx-post="{% url 'deletepicture' x.id 'built' %}" hx-trigger="click" hx-target="this"> <a href="{% url 'deletepicture' id=x.id property='built' %}" class="btn btn-primary">Delete</a> {% endif %} </div> {% endfor %} </div> It would delete it and would be clickable when I click on the href link BUT this creates me two problems: a) It changes the URL of my browser page to something like this: http://localhost:8000/dashboard/deletepictures/37/built/ where 37 is the id of the picture, it of course changes to 37, 38 etc depending on which picture I hover. b) Because on the same page I have an upload button to add more pictures, … -
