How to solve in Django REST API the serializing of data from 2 models with ForeignKey
I was wondering what the correct way is to serialize data in Django REST API from 2 models connected with ForeignKey. The situation is: i have a 1st table called NewUsers with the user registrations, and a 2nd table called Ticker with data saved from an external API. The goal is: create a 3rd table with parts of the 2 tables interconnected - one part is the user loggedin, and the other part is the selection of one crypto object. This new table will then be displayed via Django REST API serializer. The problem is: this new 3rd table does not display the complete list of values selected by the user. I have gone through the documentation here https://books.agiliq.com/projects/django-admin-cookbook/en/latest/override_save.html and here https://www.django-rest-framework.org/tutorial/1-serialization/ but could not find a complete solution. What am i missing? my views.py from rest_framework import generics from .serializers import WatchlistSerializer from ticker.serializers import TickerSerializer from watchlist.models import SectionWatchlist from ticker.models import Ticker import requests from rest_framework.views import APIView from rest_framework.decorators import api_view from rest_framework.pagination import PageNumberPagination from rest_framework.response import Response class CreateSectionWatchlist(generics.CreateAPIView): queryset = SectionWatchlist.objects.all() serializer_class = WatchlistSerializer class ListSectionWatchlist(generics.ListAPIView): queryset = SectionWatchlist.objects.all() serializer_class = WatchlistSerializer def get_queryset(self): queryset = SectionWatchlist.objects.all() author = self.request.query_params.get('author') if author: queryset … -
Django REST + Vue JS app authentication breaks when uploading?
I am developing a simple app using Django REST framework for the backend and with a Vue multi-page app as a front end. I use axios to make requests to Django from the javascript. Locally, everything works well. All the pages work and login functionality works fine. For authentication, I am using Django's built in authentication and a store in Vuex. However, once I started to deploy, it seems to break. To deploy, I initially decided to use ngrok to create an https tunnel to the backend. My frontend is still on localhost, but as soon as I change the url to use the new API, the login functionality stops working. The rest of the site (which does not require login) works fine, but the bits that do just don't work. When I click the login button, Vue tries to redirect me to the logged in 'dashboard' page, but then it identifies that I am not logged in and kicks me out. The actual login process works and the server responds that I am logged in, but when the site checks again it responds that I am not logged in. There are no errors at any point. I am happy … -

How would you implement this form feature on Glassdoor with Django?
Glassdoor has a particular feature in their 'Add a Salary' form I'm trying to replicate. I have an idea how I'd like to do it but wanted to see if there were more optimal solutions. As you type in an 'Employer's Name' a request is made back to the server to search for all Employers that have that string in their name. They present these below the form for you to select. This could be done with Ajax. They then have an 'Add a new employer' field at the bottom of the search results if the result returns None, or not what you're looking for. If you select this field some additional fields are added, like 'company address' and 'company website'. I think this could be done with a toggle showing/hiding those form fields. So the initial state of the form fields are hidden. The toggle to show the extra form fields only become available if the user clicks on 'Add a new employer'. Additionally, if the user goes back and updates the company name to one that's already in the db, the extra form fields are hidden once more. I think Ajax + a toggle and hidden form fields … -
How to package plain JSON content in a WSGI response?
I have a Django WSGI (not my decision) website making a call to fetch dynamically generated JavaScript. I put the function in views.py and it's receiving the request and doing the work, but the return value is being rejected. The HTML (JavaScript section of web page) that calls this function does it like this: var jscript = document.createElement('script'); jscript.id = 'generate'; jscript.style.visibility = 'hidden'; jscript.style.display = 'none'; jscript.src = `/generate?callback=catchOptions${query}`; // jsonp https://en.wikipedia.org/wiki/JSONP query is a list of parameters in query string format if (document.getElementById("generate") == null) document.body.appendChild(jscript); // javascript needs this to work properly There's map file that maps /generate to /generate_planet (see below). Getting into the function works great. It's the return value that Djangoff is rejecting. Here is the function in views.py from cgitb import reset from django.shortcuts import render from . import planetor from django.http import JsonResponse def generate_planet(request): res = planetor.generate(request.content_params, "/app/planetor/", "FRAMES=1") # res is JSON text, NOT a python dict return res # res looks like this: `enter code here`{'camera_location': '-30,-30,-30', 'camera_angle': '30', 'sun_color': '5,5,5', 'sun_position': '10000,0,-10000', 'planet_size': '20.06', 'background': 'background_2.jpg', 'planet': 'surface_1.jpg', 'clouds_size': '1.02', 'clouds': 'clouds_16.jpg', 'clouds_density': '0.80', 'atmosphere': 'iodine', 'atmosphere_density': '0.95', 'atmosphere_size': '1.03', 'moons': '4', 'moon_position': None, 'moon_size': None, 'moon': None, … -
'NoneType' object has no attribute 'customer_id'
I have two models in an app called customer. The models are Customer and Account. The logic is one customer can have many accounts. So the auto generated default 'id' column in Customer is Foreign Key in Account. Account also has an auto generated default 'id' column. I have created a function for an account_id field in Account which will be generated on a simple algorithm. customer_id and id from Account will be concatenated as 'customer_id'_'id', (for eg. 1_1). The function will first check the current customer_id of the Account instance created and then check which is the last id for that customer_id. For newly added account, it will capture the id part from account_id (i.e. the part after underscore) and increment it by 1. Then concatenation happens for the same customer_id and id. Following is the code-: models.py from asyncio.windows_events import NULL from django.db import models from django.db.models.signals import pre_save from django.contrib.auth.models import AbstractBaseUser from .utils import set_account_id class Customer(AbstractBaseUser): name = models.CharField(max_length=50) phone = models.BigIntegerField(null=True) email = models.EmailField(max_length=100, null=True) org_name = models.CharField(max_length=100, null = True) org_logo = models.ImageField(upload_to='logos', blank=True) subscription_start_date = models.DateField() subscription_end_date = models.DateField() password = models.CharField(max_length=50, blank=True, null=True) USERNAME_FIELD = 'email' REQUIRED_FIELDS = ['name', 'email'] def … -
Creating a windows service for connecting python and run Django server-----
Step-1: Open Visual Studio, go to File Menu, select New Project (Ctrl+Shift+N). A new window will open to create a project. Search for Windows Service (C#) from the upper right corner search box. If you do not get any Windows Service, your visual studio need to install properly (install .NET Desktop Development). Give a service name PythonService and select OK. Step-2: After creating service project, User will get 04 files by default- App.config, Program.cs, ProjectInstaller.cs, Service1.cs App.config is to configure any app data or creating connection Program.cs will initiate the service ProjectInstaller.cs is the installer for service. Double click on it. Click right button and add service installer. serviceInstaller1 will be added on serviceProcessInstaller1. Select property of serviceInstaller1, give a ServieName, change StartType to Automatic (if needed). Go to serviceProcessInstaller1 property, change Account to LocalSystem Step-3: Service1.cs file will consist all the necessary code for python cmd run and execute python command. Then Django server will run. The code for core python command run is- public partial class Service1 : ServiceBase { private System.Timers.Timer timer = new System.Timers.Timer(); int ScheduleTime = Convert.ToInt32(ConfigurationManager.AppSettings["ThreadTime"]); string _workingDirectory = ConfigurationManager.AppSettings["WorkingDirectory"]; string _RunServerCommand = ConfigurationManager.AppSettings["RunServerCommand"]; int sent = 0; public Service1() … -
CS50W Django sessions
I'm currently working on CS50W and have a problem with the concept of Session in Django: When introducing the notion of session, the global variable 'tasks = []' is implemented in user's session. My problem is that in the add function, tasks.append(task) is no longer defined. I have this exact code: from django import forms from django.http import HttpResponseRedirect from django.shortcuts import render from django.urls import reverse # Create your views here. class NewTaskForm(forms.Form): task = forms.CharField(label = "New Task") def index (request): if "tasks" not in request.session: request.session["tasks"] = [] return render(request, 'tasks/index.html', { "tasks" : request.session["tasks"] }) def add (request): if request.method == "POST": form = NewTaskForm(request.POST) if form.is_valid(): task = form.cleaned_data["task"] tasks.append(task) return HttpResponseRedirect(reverse("tasks:index")) else : return render (request, 'tasks/add.html', { "form": form }) return render(request, 'tasks/add.html', { "form":NewTaskForm() }) I've tried to replace 'tasks.append(task)' by 'request.session["tasks"]' but it doesn't work. -

M2M attribute error with FOO_set.all() and FOO not a queryset
Having a problem with a M2M related queryset: simplified model is class Category(models.Model): name = models.CharField(max_length=200) class Product(models.Model): name = models.CharField(max_length=200) category = models.ManyToManyField( Category, blank=True, null=True, related_name="categorytest") I usually do related queries using related name (which works fine here no problem) yet I wanted to try "set_all()" in this case. Say I do: elecs = Category.objects.get(name="Electronics") then: elecs.product_set.all() I get AttributeError: 'Category' object has no attribute 'product_set'. I am a bit surprised because this is an error that happens when using a queryset instead of a model instance yet, if a confirmation was needed, a type(elecs) gives me <class 'store.models.Category'>. I migrated/erased db multiple times, no change. Any idea ? Thanks -

Forbidden <URL> User Registration Python Django
I created a Patient model in models.py file and then used a serializer to convert the data. Previously, I was using the built-in User model and serializers to perform user registration, email verification and login. But I had to add extra fields and thought it would be better to make a separate table in the DB. I've made the migrations and the changes, but I get the forbidden error.

How to get reverse relationship object django annotate with subquery?
It's not a good structure, but it's an example This is my sample model class Book(models.Model): name = models.CharField(max_length=50) class Borrower(models.Model): book = models.ForeignKey(Book, on_delete=models.SET_NULL, null=True) name = models.CharField(max_length=50) age = models.IntegerField() class OwnerCard(models.Model): certification_date = models.DateField() class Owner(models.Model): owner_card = models.ForeignKey(OwnerCard, on_delete=models.SET_NULL, null=True) book = models.ForeignKey(Book, on_delete=models.SET_NULL, null=True) name = models.CharField(max_length=50) age = models.IntegerField() I want to use reverse relationship to get the object of the Borrower and Owner from the Book Model Like this from django.db.models import Subquery, OuterRef Books = Book.objects.all().annotate( borrower=Subquery(Borrower.objects.get(user=OuterRef('user'))), owner=Subquery(Owner.objects.get(user=OuterRef('user'))) ) Or Books = Book.objects.all().annotate( borrower=Subquery(Borrower.objects.filter(user=OuterRef('user')).first()), owner=Subquery(Owner.objects.filter(user=OuterRef('user')).first()) ) and I want use print(Books[0].brrower.name) >>> brrower's name print(Books[0].owner.owner_card.certification_date) >>> certification date But, it's not working. don't have to use annotate or subquery. Is there a way to implement it this way? -

If you edit venv\Lib\site-packages\grappelli\templates\admin\change_list.html, The button appears, but it’s not the case... How can I make grappelli see my button? -
