Creating Profile with Django Signals: Custom user field not showing up in signal
I currently have a custom user model that triggers a signal which creates an associated profile. My problem is that I need the signal to create a different type of profile depending on the user type selected during user creation. For whatever reason, it seems that I am able to access the user instance but not the instance.user_type in my signal. I've been searching all over for a similar case and I just can't figure out what I am doing wrong. My signal and user model are below: in users.signals.py @receiver(post_save, sender=User) def build_profile_on_user_creation(sender, instance, created, **kwargs): if created: if instance.user_type == 'T1': profile = Type1(user=instance) profile.save() if instance.user_type == 'T2': profile = Type2(user=instance) profile.save() in users.models.py class UserManager(BaseUserManager): def _create_user(self, email, password, is_staff, is_superuser, user_type, **extra_fields): if not email: raise ValueError('Users must have an email address') now = timezone.now() email = self.normalize_email(email) user = self.model( email=email, is_staff=is_staff, is_active=True, is_superuser=is_superuser, last_login=now, date_joined=now, user_type=user_type, **extra_fields ) user.set_password(password) user.save(using=self._db) return user def create_user(self, email, password, **extra_fields): return self._create_user(email, password, False, False, **extra_fields) def create_superuser(self, email, password, **extra_fields): user=self._create_user(email, password, True, True, **extra_fields) return user class User(AbstractBaseUser, PermissionsMixin): email = models.EmailField(max_length=254, unique=True) name = models.CharField(max_length=254, null=True, blank=True) is_staff = models.BooleanField(default=False) is_superuser = models.BooleanField(default=False) … -
Django signals does not work with get_user_model()
I am trying to add profile picture to user when user is created but upon creating user when I try to log in I get User has no profile, even when I try to log in into Django admin with superuser. This error is caused by instance.profile.save() in signals.py file. Here is my signals.py: from django.contrib.auth import get_user_model from django.db.models.signals import post_save from django.dispatch import receiver from .models import Profile User = get_user_model() @receiver(post_save, sender=User) def create_profile(sender, instance, created, **kwargs): print('inside signals') print(created) if created: Profile.objects.create(user=instance) @receiver(post_save, sender=User) def create_profile(sender, instance, **kwargs): print('inside profile create') instance.profile.save() Here is my Profile model: from django.db import models from django.conf import settings # Create your models here. User = settings.AUTH_USER_MODEL 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" Here is my register view: User = get_user_model() def register_view(request): form = RegisterForm(request.POST or None) if form.is_valid(): username = form.cleaned_data.get('username') email = form.cleaned_data.get('email') password = form.cleaned_data.get('password1') password2 = form.cleaned_data.get('password2') try: user = User.objects.create_user(username, email, password) except: user = None if user != None: # request.user == user # login(request, user) return redirect('login') else: request.session['register_error'] = 1 return render(request, "recipe/forms.html", {'form': form, 'title': 'Join Today'}) I did import accounts.signals … -

mock attribute assertion failure
I am relatively new to python testing. I am using unittest.mock to test a Django view function. I am mocking a model. I am using TDD and once the view layer has got all its test passed, I will implement the changes in the model. def new_list(request): form = ItemForm(data=request.POST) if form.is_valid(): list_ = List() list_.owner = request.user print(list_.owner) list_.save() form.save(for_list=list_) return redirect(list_) else: return render(request, 'home.html', {'form': form}) The test code is as follows: @patch('lists.views.list') @patch('lists.views.ItemForm') def test_list_owner_is_saved_if_user_is_authenticated( self, mockItemFormClass, mockListClass): user = User.objects.create(email='a@b.com') self.client.force_login(user) self.client.post('/lists/new', data={'text': 'new item'}) mock_list = mockListClass.return_value self.assertEqual(mock_list.owner, user) The error that I get is as follows: FAIL: test_list_owner_is_saved_if_user_is_authenticated (lists.tests.test_views.NewListTest) Traceback (most recent call last): File "/Library/Frameworks/Python.framework/Versions/3.7/lib/python3.7/unittest/mock.py", line 1204, in patched return func(*args, **keywargs) File "/Users/asim/python-projects/django-todo-list/superlists/lists/tests/test_views.py", line 181, in test_list_owner_is_saved_if_user_is_authenticated self.assertEqual(mock_list.owner, user) AssertionError: <MagicMock name='list().owner' id='140457579271392'> != <User: User object (a@b.com)> I thought that Magic mock will return any assertion true.

Add/remove elements from an array via Fetch
I have data in JSON format like this: [{"user": "shopaholic3000", "followers": ["Moderator", "poetry2"]}] I want to use a Fetch API to add and remove users from the followers array.

I came up with this: function followUser(username){ fetch(`/profile/${username}/followers`) .then(response => response.json()) .then(profile => { console.log('checkpoint1') let followBtn = document.querySelector('[name="follow-user"]') let currentUser = document.querySelector('#current-user').value if (followBtn.innerHTML = "Follow (+)"){ fetch(`/profile/${username}/followers`, { method: 'PATCH', headers: { 'Content-Type': 'application/json', }, body: JSON.stringify({ followers: followers.push(currentUser) }) }) .then(response => response.json()) .then(profile => { console.log('checkpoint2') }) } }) } This showed an error in console: ReferenceError: followers is not defined. views.py def follower(request, user_username): try: user_profile = Profile.objects.filter(user__username=user_username) except Profile.DoesNotExist: return JsonResponse({"error": "No profile found."}, status=404) if request.method == "GET": return JsonResponse([user.serialize() for user in user_profile], safe=False) elif request.method == "PATCH": data = json.loads(request.body) user_profile.followers = data["followers"] user_profile.save() return HttpResponse(status=204) else: return JsonResponse({ "error": "GET or PATCH request required." }, status=400) urls.py path("profile/<str:user_username>/followers", views.follower, name="followers") How can I go about this? -

Serializing a list of same class, but different "type" objects
Let's suppose I had a Test class in my django app and TestItem class. After that I have multiple child classes of TestItem, e.g. ChoiceTestItem (multi-table inheritance). Now it would be nice to return a list of the items in Test retrieve views, so I would like my serializer to output something like { "pk": 1, "name": "My example test", "items": [ { "pk": 1, "title": "How are you?", "type": "comment" }, { "pk": 2, "title": "How old are you?", "type": "choice", "choices": [ { ... }, { ... } } } ] } To acomplish that, I created a meta serializer, that returns another serializer depending on my items' item_typ property, like so: class TestItemBaseSerializer(serializers.ModelSerializer): class Meta: model = models.TestChallengeItem fields = [ 'pk', 'title' ] class ChoiceItemSerializer(TestItemBaseSerializer): class Meta(TestItemBaseSerializer): model = models.ChoiceItem # NOTE: Additional fields for this type of test item ! <--------------------- fields = TestItemBaseSerializer.Meta.fields + [ 'min_answers', 'max_answers', ] class TestItemSerializer(serializers.ModelSerializer): @classmethod def get_serializer(cls, model, item_type): item_type_serializers = { 'choice': ChoiceItemSerializer, ... } if item_type in item_type_serializers: return item_type_serializers[item_type] raise serializers.ValidationError(_("Unknown item type: " + item_type)) def to_representation(self, instance): serializer = self.get_serializer(instance.__class__, instance.item_type) return serializer(instance, context=self.context).data But it looks like I can't access ChoiceItem fields … -
I dont see Django profile update form in my templates

HTML {% if not user.is_authenticated %} <script> window.onload = () => { window.location.href = "{% url 'main' %}"; } </script> {% else %} <h3>I am {{ user.username }}</h3> <img src="{{ user.profile.image.url }}" width="300"> {% endif %} <!-- User Update Forms --> <form method="POST" enctype="multipart/form-data"> {% csrf_token %} {{ u_form|crispy }} {{ p_form|crispy }} <button type="submit">Update</button> </form> update form in forms.py class UserUpdateForm(forms.ModelForm): email = forms.EmailField() first_name = forms.CharField(min_length=5, max_length=30) def supervalid(self): expr_a = User.objects.filter(first_name=self.cleaned_data['first_name']).exists() expr_b = User.objects.filter(email=self.cleaned_data['email']).exists() if expr_b: raise ValidatioError(f'There already exists user with that email, use another one ;)') if expr_a: raise ValidatioError(f'This name is already used, sorry') class Meta: model = User fields = ['username', 'email', 'first_name'] def __init__(self, *args, **kwargs): super(UserUpdateForm, self).__init__(*args, **kwargs) class ProfileUpdateForm(forms.ModelForm): class Meta: model = Profile fields = ['image'] views.py @login_required def profile(request): if request.method == 'POST': u_form = UserUpdateForm(request.POST, instance=request.user) p_form = … -
recipient_list isn't getting the email address in django
I'm having trouble with smtp email sending in django. I tried to get the email address using User model => get_email = User.objects.filter(is_admin=True).values_list('email') But when I pass it to recipient_list,it can't find the email address. Here is my views.py: from django.shortcuts import render from feedbacks.models import Feedback from django.contrib import messages from django.core.mail import send_mail from django.conf import settings from django.contrib.auth import get_user_model User = get_user_model() def feedback(request): status = Feedback.objects.all() get_email = User.objects.filter(is_admin=True).values_list('email') print(get_email) if request.method == 'POST': name = request.POST["name"] student_id = request.POST["student_id"] adviser_init = request.POST["adviser_init"] phone = request.POST["phone"] email = request.POST["email"] issues = request.POST["issues"] obj = Feedback.objects.create(name=name, student_id=student_id, adviser_init=adviser_init, phone=phone, email=email, issues=issues) obj.save() try: subject = 'Student Feedback' message = "Mail from Student ID:" + student_id + "\nIssue:" + issues + "" email_from = settings.EMAIL_HOST_USER send_mail(subject, message, email_from, [get_email]) messages.success(request, 'Your issue has been sent to our admin.

Thank You!') except: messages.error(request, 'Feedback Saved but not send to admin.') context = { 'status': status } return render(request, 'feedback/feedback.html', context) -
Wagtail with get_full_url is redirecting to non SSL link
I am using get_full_url to get the link of pages in my wagtail application but it redirects from HTTPs to HTTP, when I changed it to get_url pr pageurl in templates, it fixed the problem and all links were redirected to HTTPs (SSL) the only problem that I faced is in the footer as it is sent in email, and it creates a server error every time I send an email with the footer bein using pageurl this is the error that I got: raise ValueError("pageurl tag expected a Page object, got %r" % page) Exception Type: ValueError at /mission/accept_plan/ Exception Value: pageurl tag expected a Page object, got '' which does not happen with get_full_url here the code in the template: <a href="{% pageurl LIBRARY %}" referrerpolicy="origin"> library is being defined in context as this library = ( Site.find_for_request(request) .root_page.get_children() .type(LibraryPage) .first() ) return { "LIBRARY": library, } when I changed to this syntaxe: <a href="{{ LIBRARY_URL }}" referrerpolicy="origin"> library = ( Site.find_for_request(request) .root_page.get_children() .type(LibraryPage) .first() ) return { "LIBRARY_URL": library.get_full_url(), } with this last syntax no server error but it redirects to https when I am on the website is there a way to fix the get_full_url to … -
Django: send confirmation email to customer AND to admins
I am sending customers a confirmation email once the Stripe webhook handler says "Okay", but would also like to send an email to the admins, so they become aware of the new order waiting to be dealt with. I added ADMINS = [("my_name", "my_email")] to my project settings and the line mail_admins(subject_admin, body_admin) to my up to that moment functioning method in the Stripe WH handler, so: from django.core.mail import send_mail, mail_admins class StripeWH_Handler: [...] def _send_confirmation_email(self, order): send_mail(subject_customer, body_customer, my_email, [customer_email]) mail_admins(subject_admin, body_admin) [...] if order_exists: self._send_confirmation_email(order) [...] But adding that line makes the method throw a server error and my webhook fails. How can I send those two emails to both customer and admin correctly? Thank you! -
Dynamically change Django form choices depending on active tab
I have a page with 4 different tabs (music genres) displaying different information depending on the tab (songs vs number of listens). At the top of the page there is a form which allows you to filter out the information on each tab (currently from/to date). I would like to add a choice field to the form, but for the choices to change dynamically depending on which tab is active. I am not sure how to go about this, or if it is possible to pass the active tab information to the web server to use as a parameter in the request. views.py: class MusicDashboard(generic.TemplateView): template_name = "support/music/dashboard.html" form_class = forms.MusicFilter def get(self, request, *args, **kwargs): self.form = self.form_class(request.GET or None) return super().get(request, *args, **kwargs) def get_context_data(self, **kwargs): context = super().get_context_data(**kwargs) context["form"] = self.form context["jazz"] = self._dashboard_context( models.Jazz, **kwargs ) context["classical"] = self._dashboard_context( models.Classical, **kwargs ) context["rock"] = self._dashboard_context( models.Rock, **kwargs ) context["country"] = self._dashboard_context( models.Country, **kwargs ) return context def _dashboard_context(self, music_cls, **kwargs): base_qs = music_cls.objects.all() from_date = self.request.GET.get("from_date") to_date = self.request.GET.get("to_date") if from_date: base_qs = base_qs.filter(released__gte=from_date) if to_date: base_qs = base_qs.filter(released__lte=to_date) ... # Some logic here to create a table of song vs amount of times listened to … -
