Run JS after Django POST Request
I am learning Django Channels and I already have a few months of basic Django experience. Essentially what I am trying to do is after the POST request is sent, to trigger the JS function that will deal with sending the message. I have the following part of views.py code if request.method == "GET": # irrelevant logic pass if request.method == "POST": msg = Message(...) msg.save() return render(request, "index.html", {"msg":str(msg)}) return render("msg":"Hello World"})` And in my index.html, I have the following relevant part: HTML: <form method="post" id="send"> {% csrf_token %} .... </form> JS: var formData = $("#send"); socket.onmessage = function(e){ formData.submit( function(event){ event.preventDefault(); var finalData = { 'msg' : "{{msg}}" } console.log(JSON.stringify(finalData)); socket.send(JSON.stringify(finalData)); formData[0].reset() }) } However, when I try printing the event in my consumers.py as follows: async def websocket_receive(self, event): print("Received", event) What I would expect is to get the text of the message, but what I get in the console is: HTTP GET / 200 [0.01, 127.0.0.1:45652] ... Received {'type': 'websocket.receive', 'text': '{"msg":"Hello World"}'} ... HTTP POST / 200 [0.02, 127.0.0.1:45652] Which means the message gets sent before the post request goes through. Is there some convenient way to fix this? Thanks for your help :) -

Django model querying for first N rows that sum up to a given number
I am sing Django 3.2 I have a model like this: class MyModel(models.Model): name = models.CharField(max_length=255) num_visits = models.PositiveSmallNumber() created_at = models.DateTimeField() class Meta: ordering = ['created_at'] I want to select the first N rows where the number of visits = 100 (as an example) A trivial (but probably DB intensive way) to do it would be to iterate through the rows in the table (i.e. elements of the queryset) - but I don't want to do that - for reasons that should be obvious. How can I write a query that fetches the first N rows where the sum of visits is a specified number? def get_rows_satisfying_visit_count(number=100): MyModel.objects.filter(/* what ? */) -
Best solution for extending user model twice (Student / Teacher)
I'm coding a application in Django where there are 2 types of users that need to login on the webapplication: teachers and students. Now I'm not sure what is the best approach for this. I already read a lot of tutorials and Stackoverflow questions that explains how to extend the user model, but I'm not sure which is the best option. The requirements: 2 kind of profiles with different fields needed (teacher and student) Possibility to have separate admin "objects" where the superstaff of the application can login in the backend and manage the separate objects. Option 1: Make use of the method to extend the AbstractUser class. This works for now, however I don't know if I can use AUTH_USER_MODEL twice (teacher and student). Now it's one profile with both fields for students and teachers. With proxy models I can show only the necessary fields for teachers or students. Option 2: (I think this is the best solution) Make 2 models (Teacher and Student) with each a Foreignkey to User (OneToOneField). Problem here is that if the Administrator of the website creates a new teacher or student, they also need to create a separate user first (that can login) … -

How to redirect to an absolute url path in django?
I am trying to reroute to the "listing" path from the the watchlist page using the 'url' attribute in Django templates. However, the problem is that Django ignores the parts of the URL it has already used in rerouting (i.e."/watchlist") and so looks for the url with path "/watchlist/listing_title" instead of just "/listing_title", which is what I want. Is there a way to work around this? urls.py path("", views.index, name="index"), path("<str:listing_title>", views.listing, name="listing"), path("watchlist", views.watchlist, name="watchlist"), watchlist.html <a href={% url 'listing' listing.title %}"> -

Not all fields are showing correctly in django admin
I've added a plan field to my custom Account class, but cannot get it to show on the individual account page in the django admin. It shows correctly in table of all accounts in the list view (as denoted by list_display), but does not show on each individual account page. Here's my Account model: class Account(AbstractUser): PLANS = ( ("free", "free"), ("pro", "pro") ) plan = models.CharField(max_length=10, choices=PLANS, default="free") def __str__(self) -> str: return self.first_name And my admin file: from django.contrib import admin from django.contrib.auth.admin import UserAdmin from accounts.models import Account from subscribers.models import Subscriber class SubscriberInline(admin.TabularInline): model = Subscriber extra = 0 class AccountAdmin(UserAdmin): inlines = [SubscriberInline, ] list_display = ("first_name", "plan", "email") # fields = ("first_name", "plan", "email") admin.site.register(Account, AccountAdmin) Why does this happen? Is the problem related to the custom Account class which inherits from the AbstractUser model? I thought to add fields to the AccountAdmin class, but that just returns the below error: ERRORS: <class 'accounts.admin.AccountAdmin'>: (admin.E005) Both 'fieldsets' and 'fields' are specified. The plan field also doesn't show in the admin panel when trying to create a new account (mind you, neither do most of the other fields as it only asks for the username, … -

Django Custom User Model migration return error : ValueError: Related model 'user_profile.customuser' cannot be resolved

Gmail verificated failed in django
I created two class in view.py to achieve account register and verificate. This is my thought.When user registers,django will send an active_link to user's gmail and now user.is_active = False.After clicking it so that user.is_active = True and account verificates successfully.The situation is that my gmail got the aitive_link,but User.objects still equals False after clicking the link. This is my registraion class. class RegistrationView(View): def get(self, request): return render(request, 'authentication/register.html') def post(self, request): username = request.POST['username'] email = request.POST['email'] password = request.POST['password'] context = { 'fieldValues': request.POST } if not User.objects.filter(username=username).exists(): if not User.objects.filter(email=email).exists(): if len(password) < 8: messages.error(request, '密码不会8位都没吧，不会吧') return render(request, 'authentication/register.html', context) user = User.objects.create_user(username=username, email=email) user.set_password(password) user.is_active = False user.save() uidb64 = urlsafe_base64_encode(force_bytes(user.pk)) domain = get_current_site(request).domain link = reverse('activate', kwargs={'uidb64': uidb64,'token': account_activation_token.make_token(user)}) activate_url = 'http://' + domain + link email_body = 'Hi ' + user.username + ' 没时间解释了快点链接认证账户\n' + activate_url email_subject = '激活你的邮箱' email = EmailMessage( email_subject, email_body, 'noreply@gmail.com', [email], ) email.send(fail_silently=False) messages.success(request, '邮箱验证完这帐户就是他娘你的了') return render(request, 'authentication/register.html') return render(request, 'authentication/register.html') This is my Verification class. class VerificationView(View): def get(self, request, uidb64, token): try: id = force_text(urlsafe_base64_decode(uidb64)) user = User.objects.get(pk=id) if not account_activation_token.check_token(user, token): return redirect('login'+'?message='+'User already activated') if user.is_active: return redirect('login') user.is_active = True user.save() messages.success(request, '账户创建成功') … -
