How to pass multiple variables or context dictionary to context processors in Django?
I have a view called shopcart() which has multiple variables. Here's the code: def shopcart(request): category = Category.objects.all() current_user = request.user # Access User Session information shopcart = ShopCart.objects.filter(user_id=current_user.id) total=0 tax = 0 grand_total = 0 for i in shopcart: total += i.variant.price * i.quantity url = request.build_absolute_uri() domain = urlparse(url).netloc biz_id = Business.objects.get(domain_name=domain) get_tax = Tax.objects.get(business__business_id=biz_id.business_id) tax_percent = get_tax.tax_percentage tax = round((tax_percent * total)/100, 2) grand_total = round(total + tax, 2) context={'shopcart': shopcart, 'category':category, 'total': total, 'tax_percent': tax_percent, 'tax': tax, 'grand_total': grand_total, } return render(request,'shop/cart.html', context) Currently, it is sending context dictionary to only one template i.e 'shop/cart.html'. But, I want to access all the variables of this context in all the templates. I know the context processors are used to make the variables available in all templates, but not sure how to properly do it in my situation. Can anybody help me. Thanks. -
I am running into an error with an npm command in react. "ERROR in main Module not found: Error: Can't resolve ..."
I have been following a django-react tutorial and ran into a problem with the command npm run dev. I thought it was a problem with the webpack file but maybe not.

Django input forms not showing up in my template
My problem is that when I go to my add.html page the input forms for title and textarea do not show up. For context, this is for an online course where I have to design a "wiki".

Django two same signal types
I don't understand how 2 signals executed together relate to each other. For example consider the following: from django.db import models from django.contrib.auth.models import User from PIL import Image from django.db.models.signals import post_save from django.dispatch import receiver class Profile(models.Model): user = models.OneToOneField(User, on_delete=models.CASCADE) image = models.ImageField(default='default.jpg', upload_to='profile_pics') def __str__(self): return f'{self.user.username} Profile' # Overriding save method-image resizing def save(self, **kwargs): super().save(kwargs) img = Image.open(self.image.path) if img.height > 300 or img.width > 300: output_size = (300, 300) img.thumbnail(output_size) img.save(self.image.path) # save() of parent class #Signals when a user is registered his profile is automatically updated @receiver(post_save, sender=User) def create_profile(sender, instance, created, **kwargs): if created: Profile(user=instance) #could do Profile.objects.create(user=instance) instead to replace the 2 lines instance.profile.save() #reverse query I understand the following: create_profile: is my receiver function. It will do something when .save() method takes place, in our case will create a Profile instance and save it. sender: is the Model that is actually signalling this to take place. So in our case, if we want a signal to take place when the save method is executed on User model then the sender would be the User. post_save is the signal Regarding my question now. I have seen the above function broken … -

django 3.1 user not staying logged in
So, I have a django 3.1 project and a Foo app that is going to have a user login, but I am running into the problem where users will not retain a logged in status after any additional requests. the code is similar to that below, but pretend that all relevant imports are made that are otherwise absent. views.py from django.shortcuts import render from django.contrib import auth from django.http import HttpResponseRedirect def login(request): if request.method == "POST": username = request.POST['username'] password = request.POST['password'] user = auth.authenticate(request, username=username, password=password) if user is not None: auth.login(request, user) if request.user.is_authenticated: return HttpResponseRedirect(reverse("Foo:stays_loggedin_check")) return render(request, template_name="Foo/loginfailed.html") return render(request, template_name="Foo/login.html") def stays_loggedin_check(request): if request.user.is_authenticated: return render(request, template_name="Foo/staysloggedin.html") return render(request, template_name="Foo/weirdly_doesnt_stay_logged_in_despite_documentaion.html") urls.py from django.urls import path from . import views app_name = "Foo" urlpatterns = [ path("login", views.login, name="login"), path("shouldnt_need_to_do_this", views.stays_loggedin_check, name="stays_loggedin_check"), ] When one fills out the login form at Foo/login.html incorrectly it, as expected, renders the page Foo/loginfailed.html. but when filled out correctly this form returns Foo/weirdly_doesnt_stay_logged_in_despite_documentaion.html. Is there a way to model behavior to be in line with django documentation where this will return Foo/staysloggedin.html instead? -
Django Class Base Views - muti model query

How to disable a particular link after used once?
Here Admin invites the user by the email, firstname, lastname and username. After user saved with (is_active=False), a link will be send to the user email address. After clicking the link user will be redirected to a view where the user can set a new password for them. What I want is, the url which will be used to set a new password should not be valid once a user sets a new password. Right now when the user sets a new password through a url, user can use the same url to reset the password again. I want to invalid this url once a user sets a new password. OR what another approach will be better in this case while inviting a new user ? urls path('set/<uidb64>/<new_token>/password/', views.set_user_password, name='set_user_password'), path('confirm/user/<uidb64>/<token>/', views.activate_account, name="activate_user"), views class AddUser(View): template = 'user/add_user.html' form = AddUserForm def get(self, request): return render(request, self.template, {'form': self.form()}) def post(self, request): form = self.form(request.POST) if form.is_valid(): user = form.save(commit=False) user.is_active = False user.save() # sending email subject = "New User Invitation" context = { 'user': user, 'domain': get_current_site(request).domain, 'uid': urlsafe_base64_encode(force_bytes(user.pk)), 'token': default_token_generator.make_token(user=user), } message = render_to_string('user/user_invitation_email.html', context) send_email.delay(subject, message, settings.EMAIL_HOST_USER, user.email) return redirect('dashboard:users_list') return render(request, self.template, {'form': form}) … -

How to toggle a wishlist button with an Ajax function in Django
So I have run into a bug that is just driving me crazy. When you open my webpage, a list of jobs are provided which have a small heart shaped wishlist icon next to them. Normally, if the job is part of your wishlist it should appear as a red icon, which if you click would have a sweetalert popup that says the job is removed from your wishlist. And if the job is not part of your wishlist it would be displayed in blue, which if you click would have a pop up that says the job has been added to your wishlist. All this works, except for when you have just loaded the page for the first time, and one of the listed jobs is NOT part of your wishlist, and displayed in blue. If you click this blue icon, instead of saying "added to wishlist" and turning red, it says "removed from wishlist" and stays blue, even though its not part of the wishlist. Clicking the button AGAIN, will then do the correct action, saying "added to wishlist" and flipping the color, so the error only occurs the first time. Something wrong with .data('wl') being set for … -

Annotate user of last revision in django-reversion
I keep track of the revisions of one of my django-models like so: @reversion.register() class MyModel(models.Model): In my views, I have a ListView for this model: class MyModelListView(ListView): model = MyModel Now: In the list/table of objects I want in one column displayed who made the last revision... i.e. the username of the last revision of the object... So my idea is something like this: def get_queryset(self): object_list = MyModel.objects.annotate(user_lastversion=reversion.reverse()[0].revision.user.get_username) But of course it is not working, since reversion has no attribute reverse. And I don't know how to merge something like Version.objects.get_for_object(MyModel.objects.get(slug=slug)).reverse()[0].revision.user.get_username into "annotate". Any help would be appreciated! -
