Django FieldError : Cannot resolve keyword 'total_sales' into field
This is the query I am running to get Total Sales for each party. Party.objects.annotate(total_sales=Sum('sales__salestransaction__total_cost')) It shows correct results.

Django Authentication without Django Admin functionality
I am working on a Rest API using Django Rest Framework. I want to add registration and authentication, but I don't know how to do it. There is a bunch of methods of doing that in official docs, but they all seem to be using Django Admin functionality (by inheriting their User classes from AbstractBaseUser), which I don't want to use. I want to do it from scratch, have my own Person class which does not use any Django Admin functionality. I am planning to disable Django Admin in my project. Is there a way to do that? -
Django - How can I send absolute url for a model from views.py to another python script?
I'm pretty new to Django and am trying to make a breadcrumbs module. It works pretty well, except I'm having trouble trying to link back to URLs which need a primary key. I've got a breadcrumbs.py file which simply looks up the list of keywords in a list and adds HTML in the form of list items. The problem is to link back to, for example, the profile of a user, I need to send the absolute_url for that profile to breadcrumbs.py. However, since I'm calling the get_breadcrumbs function from within views.py, I can't directly send the request object as an argument in extra context. models.py: class Profile(models.Model): user = models.OneToOneField(User, on_delete=models.CASCADE) role = models.ForeignKey(Role, on_delete=models.SET_DEFAULT, blank= True, default=Role.get_default) image = models.ImageField(default='profile_pics/default.png', upload_to = 'profile_pics') def __str__(self) -> str: return f"{self.user.username}'s profile" def get_absolute_url(self): return reverse("profile", kwargs={"pk": self.pk}) views.py: from apps.backend_utils.breadcrumbs import get_breadcrumbs class ProfileView(LoginRequiredMixin, DetailView): model = Profile template_name = 'users/users_profile.html' extra_context = { 'breadcrumbs': get_breadcrumbs(['home']), 'page_title' : 'Profile', } breadcrumbs.py: from django.urls import reverse_lazy breadcrumb_lookup = { 'home': { 'title' : 'home', 'url_name': 'home', 'icon_class' : 'fas fa-home', }, 'profile': { 'title' : 'Profile', }, ...[Code omitted]... } for k, v in breadcrumb_lookup.items(): if 'url_name' in v.keys(): v.update({'url': … -

Django Rest Framework how to check an object is exists or not?
I'm trying to check if an object is exists or not and this is how I do: try: control = Card.objects.filter(cc_num = cc_number)[0] exists = True except (IndexError): exists = False It works but I wonder if there is a more practical way to do? (The reason I use except(IndexError) is I'm finding the object with typing [0] to end of model.objects.filter().) -

How to get the instance of a model from inlines in django ModelAdmin
Example: Suppose I have two models: from django.db import models # Create your models here. class Author(models.Model): name = models.CharField(max_length=5, default='admin') def __str__(self): return self.name class Book(models.Model): active = models.BooleanField(default=True) name = models.CharField(max_length=5, default='admin') author = models.ForeignKey(Author, null=True, on_delete=models.CASCADE) upload = models.FileField(upload_to ='uploads/', null=True) def __str__(self): return self.name And this is my admin setup: from django.contrib import admin from .models import Author, Book class BookInLine(admin.StackedInline): model = Book extra = 0 @admin.register(Author) class AuthorAdmin(admin.ModelAdmin): list_display = ['name'] inlines = [BookInLine] def get_inline_object(self, request): inlineObject = self.get_inline_instances(request)[0] #this gives me access to BookInLine object. #an example of what I need to get is: return inlineObject.instance The problem is, ModelInLine objects have no attribute instance associated with them. I can get the parent instance, that is the instance of the Author model by writing the following method in the BookInLine class: def get_parent_object_from_request(self, request): resolved = resolve(request.path_info) if resolved.kwargs: return self.parent_model.objects.get(pk=resolved.kwargs["object_id"]) return None this will give me the instance of the Author model, what I need is to access the instance of Book model associated with that change_view.

Django - Diplay a form in a modal
I'm building a Django application and I try to display one of my forms in a modal window. It has been initially developed for a normal one, the scripts worked fine, but I cannot manage implement properly the modal. The context is classical: a window displays a list of objects with, for each of them, a button to edit it, and an additional global button to create a new object. Each button is supposed to open the same modal. It could have become easy if I did not have several js scripts dedicated to the form, because they are my issue: the do not work properly now that the form is in a modal. So there is something I did wrong, and at the end I'm not even sure my approach is the best one. The modal is displayed using bootstrap, HTML code is the following: <div id="grp_detail" class="modal fade hide" role="dialog" tabindex='-1'> <div class="modal-dialog modal-lg"> <div class="modal-content form_content"> {% include './adm_group_detail.html' %} </div> </div> </div> Tell me if you need the included template - it's quite big because the form is a bit tricky. The view that displays de page with the list is the following: @user_passes_test(lambda u: u.is_superuser … -
Define email subject in a Django template
Say I want to send an email using the send_mail() method. The body of the email lives in templates/email.html. I would like to define the email subject in the same file to keep things in one place. But send_mail() needs the subject in a separate variable. So I came up with an ugly hacky way to do it. I start the template like this: {% comment "The second line of this template will be used as email subject" %} Congratulations, your account was created! {% endcomment %} And then extract it in the code like this: template = loader.get_template('email.html') subject = template.template.source.splitlines()[1] This works, but I dislike this solution. Is there an easier and more readable way to do this? More generally, can I define a variable in Django template and then extract it in the application? Something like template.get_variable("email_subject")? -
django-cors-headers does not allow a request from an allowed origin
The problem that I am facing is that I cannot fetch an existing user from my NextJS frontend. The backend framework that I use is Django (along with the django-cors-headers package). django-cors-headers does not allow a certain HTTP request, while it should. My next.config.js contains a rewrite, so that I can access my backend. async redirects() { return [ { source: '/api/:path*', destination: 'http://localhost:8000/:path*/', permanent: true, }, ] }, And my django-cors-headers settings look like this: # CORS CSRF_TRUSTED_ORIGINS = [ 'http://localhost:3000', ] CORS_ALLOWED_ORIGINS = [ 'http://localhost:3000', 'http://localhost:8000', 'http://127.0.0.1:3000', 'http://127.0.0.1:8000', ] CORS_ALLOW_ALL_ORIGINS = True The request that fails attempts to fetch a user with an ID of 1. This user exists and therefore, this request should succeed. fetch(`/api/users/${String(userId)}/`, { mode: 'cors', credentials: 'include', headers: { 'Content-Type': 'application/json', }, }) However, the only thing that I get back from the request is an error message about CORS. Cross-Origin Request Blocked: The Same Origin Policy disallows reading the remote resource at http://localhost:8000/users/1. (Reason: CORS header ‘Access-Control-Allow-Origin’ missing).
