django custom sign up form with dropdown field, allauth
so, I am using django allauth with custom signup form and page. I am trying to make usermanager to pickup vendor name and vendor code on signup page from vendorinfo class. So if I select vendor name on dropdown box on sign up page, it should automatically select vendor code that matches with vendor name field. How can I accomplish this? This is all auth so I didn't even need to create view for signup page. it just picks up signup.html from my template to generate form. forms.py class MyCustomSignupForm(SignupForm): name = forms.CharField(max_length=30, label='Name') vendor_name = dropdown vendor_code = dropdown that matches with vendor name model.py class VendroInfo(models.Model): vendor_code = models.IntegerField('Vendor Code', primary_key=True) vendor_name = models.CharField('Vendor Name', max_length=50) class UserManager(BaseUserManager): def _create_user(self, name, vendor_name, vendor_code, password): if not email: raise ValueError('Users must have an email address') now = timezone.now() email = self.normalize_email(email) user = self.model( name = name, vendor_name=vendor_name, vendor_code=vendor_code ) user.set_password(password) user.save(using=self._db) return user def create_user(self, name, vendor_name, vendor_code, password): return self._create_user(self, name, vendor_name, vendor_code, password) -
Django conditional inserts in multiple fields
I have two Django model: Object and Purchases. On the Object model, there are two fields: date_most_recent_purchase and date_first_purchase. I am inserting many dictionnaries, and each dictionnary can have the following values (of course, the date and object_id can be any value): {"object_id": 1, "date_purchase": None, "date_first_purchase": None} {"object_id": 1, "date_purchase": None, "date_first_purchase": "2020-11-11"} {"object_id": 1, "date_purchase": "2019-12-12", "date_first_purchase": None} {"object_id": 1, "date_purchase": "2018-2-10", "date_first_purchase": "2018-2-2"} Below are my Django models: class Object(models.Model): object_id = models.IntegerField(unique=True) date_first_purchase = models.DateField(null=True) date_most_recent_purchase = models.DateField(null=True) # this second model is not very important here class Purchase(models.Model): purchase_id = models.IntegerField(unique=True) date_purchase = models.DateField(null=True) (For a given object_id, I have many purchases) I would like to define some rules: if for a given object_id, there is no date_most_recent_purchase (= null) in DB, but a date_first_purchase in the dictionary (such as {"object_id": 1, "date_purchase": None, "date_first_purchase": "2020-11-11"}), we should set the value of date_first_purchase in DB for field date_most_recent_purchase. We should apply the same logic in the other case: date_first_purchase is null in DB, and dictionary contains a value such as {"object_id": 1, "date_purchase": "2019-12-12", "date_first_purchase": None} If date_first_purchase is set in DB, but the dictionary contains a value with a lower value of date_first_purchase, we … -
How to create multiple objects using django formset
Googling, I succeeded in creating multiple objects in one page using formset in Django. But I want to add all fields from Class Model 'Supporting' to form. The code below is a form that accepts only the 'hour' field. If I enter fields except for the 'hour' field once, I want it to be saved as the same value as the hour field is added. In other words, I want all fields to be input and only the 'hour' field to be added when needed. How do I add the rest of the fields? forms.py? I've tried several things for several days, but it doesn't work. please help.... [models.py] class Supporting(models.Model): date = models.DateTimeField(blank=True, null=True) student = models.ForeignKey(Student, on_delete=models.CASCADE, blank=False, null=True) kinds = models.CharField(max_length=50, choices=KINDS_CHOICES, blank=True, null=True) hour = models.CharField(max_length=2, blank=True, null=True) teacher = models.CharField(max_length=50, blank=True, null=True) comment = models.TextField(blank=True, null=True) [forms.py] from django import forms from django.forms import modelformset_factory, ModelForm, DateTimeInput from .models import Supporting SupportingModelFormset = modelformset_factory( Supporting, fields=('hour',), extra=1, widgets={'hour': forms.TextInput(attrs={'class': 'form-control'}), 'date': forms.DateTimeInput(format=('%Y-%m-%d %H:%M'), attrs={'autocomplete': 'off', 'type': 'datetime'}) } ) [views.py] def add_supporting(request): if request.method == 'GET': formset = SupportingModelFormset(queryset=Supporting.objects.none()) elif request.method == 'POST': formset = SupportingModelFormset(request.POST) if formset.is_valid(): for form in formset: if form.cleaned_data.get('hour'): form.save() … -
Djagno rest view file structure with complex calculations
I'm writing django rest api. I'll be taking form which will be sent from frontend. Form will contain data which I'll be using for performing calculation. But there is a problem. Based on form data code should execute different calculation types. So for example form { "type": 1, "form": 3, "method": } Then I should read "type". It should lead rest of form to another View method called for example type1. Then using "form" it should go for another view method form3 etc. Should I write that long api views methods or maybe I should create another file for performing calculations based on form data? Example (I will not attach serializer validation etc there): class SubmissionView(APIView): def post(self, request): if request['type'] == 1: self.type1(request.data) elif request['type'] == 2: self.type2(request.data) ........ def type1(self, request_data): if request['form'] == 1: self.form1(request.data) elif request['form'] == 2: self.form2(request.data) etc... -
Create Django URL inside JS function based on 3 different models
I have a function that displays titles from 3 different models in Django. I want to add a link to each title so it redirects the user to the proper URL. The search_autocomplete function returns all titles properly in 1 list, however, I am struggling with the creation of the URL address in the js file. I am using this library to create a list of titles. Let's say that the user puts "python is amazing" in the search bar. The URL address should contain rootURl/modelUrl/slug. If the title comes from the article model then it should look like this: http://127.0.0.1:8000/article/python-is-amazing If the title comes from the qa model then it should look like this: http://127.0.0.1:8000/qa/python-is-amazing If the title comes from the video model then it should look like this: http://127.0.0.1:8000/video/python-is-amazing The second issue is that I want to display a list of titles in autocomplete list but I need to pass the slug field to the URL address. How can I do that? js file //root URL const rootUrl = 'http://127.0.0.1:8000' //models URLs const articleURL = 'article' const qaURL = 'qa' const videoURL = 'video' new Autocomplete('#autocomplete', { search: input => { const url = `/search/?title=${input}` return new Promise(resolve … -

How to add item to cart after the user login ? #django
I'm completely new to Django and I tried to create a simple eCommerce web application. In my code, when the user is not logged, items are easily added to the cart and displayed to the web application but when the same user logged into the application and tries to add the item to the cart it is not displayed in the frontend but the item is added to user from backend. I tried the logic if user.is_authenticated but I was not able to succeed. from carts.models import Cart, CartItem def add_cart(request, product_id): product = Product.objects.get(id=product_id) try: cart = Cart.objects.get(cart_id=_cart_id(request)) except Cart.DoesNotExist: cart = Cart.objects.create( cart_id = _cart_id(request) ) cart.save() try: cart_item = CartItem.objects.get(product=product, cart=cart) cart_item.quantity += 1 cart_item.save() except CartItem.DoesNotExist: cart_item = CartItem.objects.create( product = product, quantity = 1, cart = cart, ) cart_item.save() return redirect('cart') This is Django code adding items to the cart before the user login. -

Why Django doesn't update an object?
I have a model Profile, which connects with User. For example I have Testuser. When I try to update his field 'money', nothing happens. I suppose it may be because I use User, instead of Profile in get_object. But if I change it to Profile, there is an error, that Profile doesn't have username field. How can I solve this problem? model: class Profile(models.Model): user = models.OneToOneField(User, on_delete=models.CASCADE) money = models.IntegerField(default=0) form: class AddMoneyForm(forms.ModelForm): class Meta: model = Profile fields = ('money',) view: class AddMoneyView(UpdateView): model = Profile template_name = 'users/money.html' fields = ['money'] def get_object(self, queryset=None): return get_object_or_404(User, username=self.kwargs.get('username'), pk=self.request.user.pk) def get_success_url(self): return reverse('account', kwargs={'username': self.request.user.username}) url: path('account/<str:username>/money/', AddMoneyView.as_view(), name='money'), -

JWT with Django Rest Framework not working in production
My application uses Django Rest Framework for the APIs and JWT for authenticating the users. Everything was working fine in my local machine. I started having problems after a deployed it to an EC2 instance. The only things that still work are the login, registration and tokens refresh. That is, when I try to log in, I receive the tokens back from the back-end, which are successfully stored in the local storage; when I try to sign up, the back-end creates the new user; and from time to time the tokens are also successfully updated. But all the other API calls fail. At the beginning, when I made an API call, I was getting back "401 Unauthorized". I believe the reason was because Apache wasn't forwarding the Authorization-Headers. So I added "WSGIPassAuthorization On" to the Apache configuration. Now I am getting "500 Internal Server Error" instead. As I already said, only API calls to login, tokens refresh and registration are working. For login and tokens refresh, I am using the default "TokenObtainPairView" and "TokenRefreshView". from rest_framework_simplejwt.views import TokenObtainPairView, TokenRefreshView urlpatterns = [ path('log-in/', TokenObtainPairView.as_view(), name='token_obtain_pair'), path('refresh-token/', TokenRefreshView.as_view(), name='token_refresh'), ] For the registration, this is the view I am using: class … -
