django.core.exceptions.FieldError: Unknown field(s) in ModelForm
After adding a ModelForm and specifying the fields, I get this error when I try to makemigrations.

Configure Nginx with Vue.js, Django Rest Framework as backend and /api/ on same server?
I am in a process of deploying my newly developed e-commerce to a Ubuntu server that I have. I have already set up Nginx for Frontend and for Backend. The whole application is working fine. The only problem is DRF API that doesn't get anything from the backend (it doesn't send emails, users can't register). All of that gets error 500. It seems to me that I still need to add /api/ to my Nginx configuration, but when I do that the whole app goes down. Could someone explain the best way to set this up in "sites-available"? Thank you! Here is my Sites-Available for Backend: upstream perulab_app_server { server unix:/webapps/perulab/venv/run/gunicorn.sock fail_timeout=0; } server { listen 8000; server_name 172.16.7.52; client_max_body_size 4G; location /static/ { root /webapps/perulab/web-backend; } location /media/ { root /webapps/perulab/web-backend; } location / { proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_set_header Host $http_host; proxy_redirect off; if (!-f $request_filename) { proxy_pass http://perulab_app_server; } } } And this is my Sites-Available for Backend: server { listen 8010; listen [::]:8010; server_name _; charset utf-8; root /webapps/perulab/web-frontend/dist; index index.html index.htm; location / { try_files $uri /index.html; } } When I use it the way it is right now, console prints this error: GET http://172.16.7.52:8000/api/v1/get-user-details/ 500 … -

Filter django query set based on whether a foreign key relationship exists
So I have two models. class Post(models.Model): id = models.OidField('object id', unique=True) class ArchivedFlag(models.Model): commit = models.ForeignKey(Commit, on_delete=models.CASCADE, related_name='archived_flag') user = models.ForeignKey(User, on_delete=models.CASCADE, related_name='archives') In views.py I have generated a list of all posts by some criteria, 'plist'. I want to filter the list based on posts that DO NOT have an ArchivedFlag object relationship. Basically the ArchivedFlag model is a tool hide certain posts. How can I do this? I'm trying to do something along the lines of plist = plist.exclude(models.ForeignKey.commit exists) but I'm unsure of the exact syntax. -

Can I use a keyword argument from another app to connect the URLs of two different aps together?
I'm currently developing an application using the Django REST Framework and Vue in which people can monitor a device's signal outputs. For some context, I created a custom user model with a unique UUID4 user ID that would be assigned to each user. This model is in a Django app that I called accounts. Similarly, I have the user's data recording sessions and associated data in separate models in an app that I call studio. My problem is this: I realized I would like to associate the data collected to the user's account and whatever session they wish to tie this data to. However, since these models are in different Django apps, I am getting the error get() got an unexpected keyword argument 'user_id' when I try to tie the URLs of the account and studio apps together. Relevant code snippets are below: models.py (in studio) from django.db import models class Session(models.Model): user_id = models.ForeignKey( 'accounts.CustomUser', on_delete=models.CASCADE) session_id = models.CharField(max_length=100, unique=True, blank=False) def get_associated_user_id(self): return (f'{self.user_id}') def __str__(self): return (f"Session ID: {self.session_id}") class LaserData(models.Model): user_id = models.ForeignKey( 'accounts.CustomUser', on_delete=models.CASCADE) session_id = models.ForeignKey('Session', on_delete=models.CASCADE) timestamp = models.DateTimeField(auto_now_add=True) laser_current = models.DecimalField(max_digits=8, decimal_places=3) laser_temperature = models.DecimalField(max_digits=8, decimal_places=3) laser_temperature_set = models.DecimalField(max_digits=8, decimal_places=3) tec_voltage_positive = … -

django - disable Invitation object creation if User object with the email exists

Need help writing tests - Django framework
I am relatively new to Python with Django, and very new to writing tests. The app I'm working with allows a teacher to assign multiple assignments to a student. On the student dashboard, an assignment should only be available if the start date <= today's date. The student should only see the first assignment in the list. I need to compose tests to cover the following: create a few new assignments with different start dates and assign them to the currently logged in student use the same query that is used for the student dashboard to make sure that the only assignments returned are the ones with a start date <= today's date make sure that the only assignment the student sees on the dashboard is the one with the earliest start date Below I have posted the assignment code from models.py, as well as views.py code that shows what displays on the student dashboard. Please let me know if additional code is needed to help me get started with this. I would like to only use the built in django.test features to write my tests for now, if possible.

How to add values for checked rows using javascript
I've uploaded a similar question in a previous post, but I'm re-posting because what I'm trying to achieve is a little clearer. We are outputting the list of students as a table. If we check the checkbox and click the Add Teacher button, we want the name of the currently logged in teacher to be added to the teacher field of the selected row. You can get the name of the currently logged in account with {{request.user.name}} . And I want it to be saved in DB by sending it to the server. <table class="maintable"> <thead> <tr> <th class="text-black text-center text-nowrap bg-secondary font-weight-bold sticky-top-custom">Name</th> <th class="text-black text-center text-nowrap bg-secondary font-weight-bold sticky-top-custom">Age</th> <th class="text-black text-center text-nowrap bg-secondary font-weight-bold sticky-top-custom">Register Date</th> <th class="text-black text-center text-nowrap bg-secondary font-weight-bold sticky-top-custom">Teacher</th> <th class="text-black text-center text-nowrap bg-secondary font-weight-bold sticky-top-custom">Select</th> </tr> </thead> <tbody> {% for student in students %} <tr student-id="{{ student.id }}"> <td>{{ student.name }}</td> <td>{{ student.age }}</td> <td>{{ student.register_date }}</td> <td>{{ student.techer }}</td> <td><input type="checkbox"></td> </tr> {% endfor %} </tbody> </table> <input type="button" value="Add Techer" class="addtecher"> Current student information is modified as follows. urls.py path('student/<int:id>/edit/', views.edit_student, name='edit_student') views.py def edit_student(request, id): student = get_object_or_404(Student, pk=id) edited_student, errors = Student.student_form_validation(request) if errors: return JsonResponse({'code': 'error', 'error': …
