I'm trying to create an edit jQuery ajax call. The code are the following: function editUser(id) { if (id) { tr_id = $("#element-" + id); data_pagamento_saldo = $(tr_id).find(".elementDatapagamentosaldo").text().replace(/\./g, "/"); $('#form-data_pagamento_saldo').val(data_pagamento_saldo); } } $("form#updateUser").submit(function() { var data_pagamento_saldoInput = $('input[name="formDatapagamentosaldo"]').val(); if (data_pagamento_saldoInput) { $.ajax({ url: '{% url "crud_ajax_update" %}', data: {'data_pagamento_saldo': data_pagamento_saldoInput, }, But django give me the following error: django.core.exceptions.ValidationError: ["The value '31/05/2020' hhas an invalid date format. It must be in YYYY-MM-DD format] How could I overcome the problem?

Django nested transactions and exceptions
For simplicity I have a nested atomic transaction in my code, basically if adding people to the movie fails (see first for loop) I'd like to display an exception specifically saying that this action failed and also roll back movie.save(), same for studios (see second for loop). But for some reason when either one fails movie.save() doesn't roll back, I get a movie saved in my database without any people or studios attached to it. people = ['Mark', 'John', 'Mark'] studios = ['Universal Studios', 'Longcross Studios'] try: with transaction.atomic(): movie = Movie(title=title, description=summary, pub_date=pub_date) movie.save() # iterate through people list, get the pk from database and add it to the movie try: with transaction.atomic(): for p in people: person = Person.objects.get(name=p) movie.people.add(person) except Person.DoesNotExist: self.stdout.write(self.style.ERROR('One or more performers from %s does not ' 'exist in database, please add them and ' 'rerun the command.' % str(people))) continue # iterate through studio list, get the pk from database and add it to the movie try: with transaction.atomic(): for s in studios: studio = Studio.objects.get(name=s) scene.studios.add(studio) except Studio.DoesNotExist: self.stdout.write(self.style.ERROR('One or more studios from %s does not ' 'exist in database, please add them and ' 'rerun the command.' % str(studios))) continue scene.save() … -
Django to heroku migrate broken
Trying to migrate my django app (sqlite) to a postgres heroku app. After i commit, I try to migrate on heroku but it gives me this error: Applying store.0002_auto_20200523_1502...Traceback (most recent call last): ....

Change empty list returned by values_list to None without QS evaluation, Django orm
I have a question about query optimization. I the serializer specified bellow, in to_representation method I add extra data to representation. In this string: data['slave_accounts_ids'] = instance.slaves.all().values_list('pk', flat=True) or None I add secondary model instances pks in form of list, but it might be no any secondary model instances attached to the primary model(User model), so that I get empty list []. Thing is that in this case I need to return to FE None instead of [] and becouse of that I filter [] by condition expression : instance.slaves.all().values_list('pk', flat=True) or None which seems to evaluate queryset to find out whether or not first value is empty or not, at least if compare instance.slaves.all().values_list('pk', flat=True) and instance.slaves.all().values_list('pk', flat=True) or None, later makes +1 number of queries in DB. Question is - is it possible somehow change emty list returned by values_list to None without evaluating queryset and making extra query to DB? Or provide some default maybe...

Creating model instances while creating a another instance in Django

So I have Basic Recipe model class Ingredient(models.Model): name = models.CharField(max_length=64, unique=True) def __str__(self): return self.name and also IngredientDetail model for Recipe model class IngredientDetail(models.Model): UNITS = ( ('G', 'gram'), ('L', 'liter'), ('KG', 'kilogram'), ('DG', 'ounce'), ('TPS', 'teaspoon'), ('TBS', 'tablespoon'), ('GL', 'glass'), ('PCS', 'pieces') ) ingredient = models.ForeignKey(Ingredient, on_delete=models.CASCADE) amount = models.DecimalField( blank=True, null=True, max_digits=5, decimal_places=2 ) unit = models.CharField( max_length=3, blank=True, null=True, choices=UNITS, default=UNITS[0][0] ) and my Recipe Model class Recipe(models.Model): title = models.CharField(max_length=64) image = models.ImageField(blank=True) prep_time = models.IntegerField() description = models.TextField() created_at = models.DateTimeField(auto_now_add=True) updated_at = models.DateTimeField(auto_now=True) ingredients = models.ForeignKey(IngredientDetail, on_delete=models.CASCADE) author = models.ForeignKey(CustomUser, on_delete=models.CASCADE) class Meta: ordering = ['-created_at'] def __str__(self): return f'{self.title} - by {self.author}' So I'm not sure if my relationships between models are good, and how would the view look like.

Django/PostgreSQL: How to get PostgreSQL hint using django.db.connections and the cursor() function
I am using Django for my app backend. Due to a legacy database, I had to write custom helper functions that execute raw SQL queries. I have this particular rollback function that I wrote and I want to be able to get the RAISE EXCEPTION USING HINT that was generated by the supplied query. When the RAISE clause in the query is encountered, the HttpResponse throws error 400 which is what I wanted. I get the HINT via the console when I print out the connection cursor. What I want now is to be able to get and store that to a variable or pass it to the HttpResponse so I can prompt it in the frontend.

How to override Django Admin Panel authentication with Google SSO?
What I want is to create some users in the standard Users table and add a Sign in with Google button on the Django Admin Panel login screen. When the user completes the sign-in process, then I should receive its details (e.g. email address) which then I will verify from the database, e.g. if a Users record with given email address exists. If yes, then I will sign-in the user on the Django Admin Panel. Is there a way to do this? -

It currently works like a charm for non registered users but I never did something like this before for the registered users so I am stuck. forms.py from django import forms from django.forms import ModelForm from .models import Message class NonAuthMessage(forms.ModelForm): class Meta: model = Message fields = "__all__" class AuthMessage(forms.ModelForm): def __init__(self): self.name = user.request.username self.email = user.request.email class Meta: model = Message fields = ["message"] models.py from django.db import models from django.utils import timezone class Message(models.Model): name = models.CharField(max_length=50) email = models.EmailField() message = models.TextField(max_length=3000) date_posted = models.DateTimeField(auto_now_add=True) def __str__(self): return self.email class Meta: ordering = ['-date_posted',] views.py from django.shortcuts import render, redirect from .models import Message from .forms import NonAuthMessage, AuthMessage def contact(request): formAuth = AuthMessage() formNonAuth = NonAuthMessage() mess = Message.objects.all() if request.user.is_authenticated: if request.method == "POST": form = AuthMessage(request.POST) if form.is_valid(): form.save() return redirect('contact') … -
"Token contained no recognizable user identification" while creating custom django jwt token
I have created my login view which on successful login returns access token and refresh token..Then on accessing any view the user have to attach this access token as bearer token in every url.. I have manually created my access token and refresh token . But i have inherited restframework_simplejwt.views.TokenRefreshView which will return an access token for each refresh token.. All this is working fine... Now i have used permission_classes((IsAuthenticated)) above my home_api_view and when i paste the access token over the homepage url it says "Token contained no recognizable user identification" my views.py @api_view(['POST','GET',]) @permission_classes([]) def login_view(request): username = request.data.get("username") password = request.data.get("password") response = Response() user = authenticate(request,username=username,password=password) if user is not None: login(request,user) user = User.objects.filter(username=username).first() #This will return directly the username . If you dont use .first() it will return a dictionary access_token = Generate_Access_Token(user) refresh_token = Generate_Refresh_Token(user) response.data={'refresh_token':refresh_token,'access_token':access_token} return response else: return HttpResponse("USERNAME or PASSWORD ERROR!!!") utils.py` def Generate_Access_Token(user): access_token_payload = { 'token_type':'access', 'exp':datetime.datetime.utcnow()+datetime.timedelta(days=0,minutes=5), 'jti': uuid4().hex, 'user':user.username, 'id':user.id, 'iat':datetime.datetime.utcnow(), } access_token = jwt.encode(access_token_payload,settings.SECRET_KEY,algorithm='HS256').decode('utf-8') return access_token def Generate_Refresh_Token(user): refresh_token_payload = { 'token_type':'refresh', 'id': user.id, 'exp' :datetime.datetime.utcnow()+datetime.timedelta(days=7), 'iat':datetime.datetime.utcnow(), 'jti': uuid4().hex } refresh_token = jwt.encode(refresh_token_payload,settings.SECRET_KEY,algorithm='HS256').decode('utf-8') return refresh_token
