DRF:user registration serializer for proxy models with nested serializers
i have a User model that inherits from AbstractBaseUser and also a proxy model that inherits from the User model with extended fields and a manager what I want to do is serialize and validate both the User model and the proxy model at the same time with nested serializers: ##manager for the user model class CustomAccountManager(BaseUserManager): def create_superuser(self, email, firstname, lastname, password, **other_fields): .... ##user model class User(AbstractBaseUser, PermissionsMixin): class TYPES(models.TextChoices): OWNER = "OWNER", "Owner" OTHERUSER = "OTHERUSER", "other user" ##user types base_type = TYPES.STUDENT type = models.CharField( _("User Type"), max_length=50, choices=TYPES.choices, default=base_type) email = models.EmailField( _("Your Email"), max_length=254, unique=True, blank=False, null=True) firstname = models.CharField(max_length=150, blank=False, null=True) lastname = models.CharField(max_length=150, blank=False, null=True) joined_date = models.DateTimeField( _("created date"), auto_now=True, auto_now_add=False) is_superuser = models.BooleanField(default=False) is_staff = models.BooleanField(default=False) is_active = models.BooleanField(default=False) last_login = models.DateTimeField( _("last login"), auto_now=True, auto_now_add=False) objects = CustomAccountManager() USERNAME_FIELD = 'email' REQUIRED_FIELDS = ['firstname', 'lastname'] def __str__(self): return self.firstname # owner model manager class OwnerManager(models.Manager): def get_queryset(self, *args, **kwargs): return super().get_queryset(*args, *kwargs).filter(type=User.TYPES.OWNER) class OwnerMore(models.Model): user = models.OneToOneField( User, on_delete=models.CASCADE, blank=False, null=True) #extra fields dedicated to this user type class Owner(User): base_type = User.TYPES.OWNER objects = OwnerManager() @property def extra(self): return self.OwnerMore class Meta: proxy = True this is my … -
Django forms passed instance object gets overridden in is_valid
I was working on a Django view that updates the a certain model object x. In POST method, I initiate a ModelForm and pass an instance of the model object x. But when I try to use x object inside if form.is_valid(): block, some values in vars(x) go None. Here's the snippet to explain the scenario. class MyUpdateView(generic.View): form_class = MyModelForm def post(self, request, *args, **kwargs): model_obj = MyModel.objects.get(id=kwargs.get("pk")) # Example: {"emp": 113, "project": 22, "salary": 28000} form = self.form_class(request.POST, instance=model_obj) print(vars(model_obj)) # works fine, shows all the data if form.is_valid(): print(vars(model_obj)) # few values go None, not reusable # Example: {"emp": None, "project": None, "salary": 28000} As we can see, when the vars checked inside the form.is_valid(), something happens to the passed instance object. What could be possibly reason behind this? -

I'm creating a blog to hopefully add to my portfolio and blog about my projects. It was going well until I stumbled across needing to use class-based views and extract URL information to create category pages. Here is my class: class CategoryPage(ListView): model = Post template_name = 'categories.html' ordering = ['-post_date'] def get_context_data(self, *args, **kwargs): cats = self.kwargs['category'] category_posts = Post.objects.filter(category=cats) context = super(CategoryPage, self).get_context_data(*args, **kwargs) context["cat"] = cats context["posts"] = category_posts return context and my urls.py: from django.urls import path, include from .views import HomeView, PostDetailView, CreatePost, UpdatePost, DeletePost, CategoryPage urlpatterns = [ path('', HomeView.as_view(), name="home"), path('post_details/<int:pk>', PostDetailView.as_view(), name='post_details'), path('post_create/', CreatePost.as_view(), name='create'), path('post_edit/<int:pk>', UpdatePost.as_view(), name='edit'), path('post_delete/<int:pk>', DeletePost.as_view(), name='delete'), path('category/category=<str:cats>/', CategoryPage, name='category') ] I've been hacking away at it for a few hours now trying this and that from different posts on here and I can't seem to find anything similar to what I'm facing. Currently I can't stop it from bringing up an error page saying init() takes 1 positional argument but 2 were given. Any help is appreciated thank you! -
Django is not loading media files on shared hosting cPanel
I am having issues loading media files uploaded by the user and displaying them via a template.html file when DEBUG = FALSE. The static files are displayed but I keep getting webaddress/media/images/image1.png 404 Not Found whenever I load the page. I followed some guides and added urlpatterns += static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT) to my urls.py but I am still getting the 404 error. I've chatted with the cPanel hosting provider and they said I do not have access to modify the cPanel Apache httpd.conf file so I am looking to have Django manage the serving of the media files since it handles the uploading of images to the media/images directory. Location where images directory is: /home/<cPanelUserName>/repositories/djangoApp/media/images settings.py MEDIA_URL = '/media/' MEDIA_ROOT = os.path.join(BASE_DIR, 'media/') template/index.html <body style="background: url('{{ background_pic.url }}'); background-size: cover; background-position: center; background-attachment: fixed;"> <div id="profile"> <img id="userPhoto" src="{{ profile_pic.url }}" alt="{{ profile_pic_title }}"> </div> </body> models.py class profilePic(models.Model): title = models.CharField(max_length=50) image = models.ImageField(upload_to='images/') class backgroundPic(models.Model): title = models.CharField(max_length=50) image = models.ImageField(upload_to='images/') views.py def index(request): imageModel = profilePic.objects.get(pk=1) backgroundModel = backgroundPic.objects.get(pk=1) return render( request, "template/index.html", { "profile_pic_title":imageModel.title, "profile_pic":imageModel.image, "background_pic_title":backgroundModel.title, "background_pic":backgroundModel.image, } ) urls.py from django.contrib import admin from django.urls import include, path from django.conf import settings from django.conf.urls.static import … -
django cannot convert queryset to list to js array
Using Django I have a view which pulls a queryset and attempting to convert to a list as context to the template which then feeds through to javascript array however it's as if the queryset is not converting to a real list as javascript validation is not accepting the list and thus validation not working. I have also created a normal list rather than from a queryset and works as I expect for my JS validation but everything I have tried in converting the queryset to a list the javascript just will not accept it to the array. I have also tried to convert the list as json as well from what I read online and still not working. I have tried my own for loop on the queryset to append to a new list but also done nothing. Please see the following code: View (manual python list which works tried and tested) mylist= ['sid', 'john'] context = {"mylist": mylist} View (first attempt at converting queryset to list) test = User.objects.values_list('username', flat=True) mylist = list(test) context = {"mylist": mylist} View (second attempt at converting queryset to list to json) test = User.objects.values_list('username', flat=True) mylist= json.dumps(list(test)) context = {"mylist": mylist} Template(with … -
