In Django, after extending the User model, how to add values to the new model?
I have extended the User model in Django with a profile model named "Account" as per 4.2 version. The Django administration panel successfully lists the "Account" model as a section, and it works wonderfully in Django Adminstration panel.

I am using following code: user = User.objects.create_user(username=username, first_name=first_name, last_name=last_name, email=email, password=password) mobile_number = user.Account.mobile_number user.save(); And I get error: AttributeError at /accounts/create 'User' object has no attribute 'Account' -

How to cancel (terminate) a running task in celery? Already tried using "AsyncResult(task_id).revoke(terminate=True)", but it doesn't work
In the django project, I use celery to run asynchronous tasks. I want to implement a function to cancel the running task. The official documentrevoke: Revoking tasks says that the "revoke(terminate=True)" method can be used. I tried it but it didn't work. Here are some ways I've tried: ... task = AsyncResult("1e8fb3f3-4253-4bec-b71a-665ba5d23004") print(task.state) 'STARTED' task.revoke(terminate=True) print(task.state) 'STARTED' app.control.revoke("1e8fb3f3-4253-4bec-b71a-665ba5d23004", terminate=True) print(task.state) 'STARTED' And eventually it still executes to completion. Has anyone encountered a similar problem? Or is there another way to achieve my needs in celery? Any help would be greatly appreciated! -
Pass request to django-filters custom widget
I'm trying to create a filter like the one in the image below (from Fiverr), it is a combination of select with options as inputs, I was able to create the widget and select an option and send its sub-input values on submit, but after the loading the values are gone and no option is selected, because the radio select value is not specified by the field so i need to get it directly from the request.GET, but i couldn't pass the reqeust to the widget, i'm seeing it on the Filter class but not in widget. My Custom Filter: `class PriceFilter(Widget): template_name = 'widgets/PriceFilter.html' def __init__(self, attrs=None, min=0, max=5000, *args, **kwargs): self.min = min self.max = max # print(self.request) print(kwargs) super(PriceFilter, self).__init__() def get_context(self, name, value, attrs=None, *args, **kwargs): context = super().get_context(name, value, attrs) context['min'] = self.min context['max'] = self.max print(self.request) print(kwargs) return context` My widget template ` Clickable inside <input class="form-check-input" type="radio" name="{{widget.name}}__selector" id="{{widget.name}}__selector" #if request.GET.price__selector==1 then ceck this#> Default radio ` My Filter `class ListFilter(django_filters.FilterSet): price = django_filters.NumberFilter(widget=PriceFilter()) class Meta: model = MainModel fields = { 'name':['contains'],'price':[] } def __init__(self, *args, **kwargs): print('kwgs') # print(args[0]) self.request = kwargs.pop('request', None) super(ListFilter, self).__init__(*args, **kwargs) self.filters["price"].request = args[0] ` -
In Dajngo, does the UserCreationForm or its parent classes handle the POST and GET logic? Or how is that handled?
I am new with django and going over some code that I don't understand. I looked through the django source code trying to find out if the class UserCreationFrom (pasted below) from Django handles the logic of POST for you, or if this is implemented elsewhere. To clarify, I have been seeing a class used for rendering the form then some type of view validating the data. It typically goes like: Form Class: class UserForm(forms.ModelForm): class Meta: model = User fields = ("first_name", "last_name") View: def update_profile(request): if request.method == "POST": user_form = UserForm(request.POST, instance=request.user) if user_form.is_valid(): user_form.save() return redirect("somewhere") else: user_form = UserForm(instance=request.user) return render(request, "profile.html", {"user_form":user_form}) That implementation makes sense. What I don't get is when there is a view that renders the form but then the form itself handles validation and leaves out the if request.method == "POST" logic as shown above. Or is this in some parent class? Is either one of these inline with django convention as well? An example: Class View: class UserSignupView(CreateView): model = CustomUser form_class = UserProfileSignupForm template_name = 'signup_form.html' def get_context_data(self, **kwargs): kwargs['is_confused'] = True return super().get_context_data(**kwargs) def form_valid(self, form): user = form.save() login(self.request, user) return redirect('somewhere') Then the form with … -
GCP-Django-IP Address based error: write EPROTO error:100000f7 OPENSSL_internal
