Django not setting csrftoken cookie
I am writing a Django app that uses Django-hosts for the subdomains. I have the main app running (currently on localhost) and I have set CSRF_COOKIE_DOMAIN = ".localhost". However when I run localhost:8000/admin/, there is no csrftoken cookie set, same as when I run api.localhost:8000/<slug>. When I remove the setting, both subdomain endpoints get a different csrftoken which doesn't work when I make an AJAX request using the localhost endpoint to api.localhost endpoint. Is there a setting I am missing? I have tried removing the setting, and using *.localhost to no avail -

Use Django Admin Widgets on any given page
This is not a duplicate! Alle the older questions either do not work, or are simply outdated. According to the Django documentation https://docs.djangoproject.com/en/3.2/topics/forms/media/ The Django Admin application defines a number of customized widgets for calendars, filtered selections, and so on. These widgets define asset requirements, and the Django Admin uses the custom widgets in place of the Django defaults. The Admin templates will only include those files that are required to render the widgets on any given page. If you like the widgets that the Django Admin application uses, feel free to use them in your own application! They’re all stored in django.contrib.admin.widgets. Here is my forms.py: from django import forms from django.contrib.admin.widgets import AdminDateWidget, AdminTimeWidget from .models import Category, Event class AntragForm(forms.Form): user = forms.CharField() day = forms.DateField(widget=AdminDateWidget(), label="Datum", required=True) category = forms.ModelChoiceField( queryset=Category.objects.all() ) start_time = forms.TimeField(widget=AdminTimeWidget(), label="Start", required=False) end_time = forms.TimeField(widget=AdminTimeWidget(), label="Ende", required=False) whole_day = forms.BooleanField(label="Ganztag", required=False) private = forms.BooleanField(label="Privat", required=False) whole_week = forms.BooleanField(label="Ganze Woche", required=False) summary = forms.CharField(label="Grund", required=False) description = forms.CharField(widget=forms.Textarea, label="Beschreibung", required=False) and here's the part of the template: <div class="row"> <div class="col"> {{ form.day|as_crispy_field}} </div> </div> I also tried without crispy-fields, but it doesn't render either, so that's not the problem.

Django Inline formsets always invalid
I am struck with inline formsets in Django. Each time I submit the formset it is considered invalid and hence the data doesn't get saved. I am a newbie in full-stack development and am learning Django. I am following Dennis Ivy's playlist on youtube and coding along with him. It is kind of an E-commerce portal where people can order stuff. Here is a link to the video where he implements inline formsets Video. It was working fine when I accepted orders through normal form i.e. one order at a time. I have done exactly as he did in his video. I also tried consulting my friends who are learning with me and also asked my mentor about it but no one could figure out what is wrong here. I browsed through the documentation but that too didn't help. Please help me out in fixing this. Github Repo link views.py from django.forms import inlineformset_factory def createOrder(request, pkCrteOrder): OrderFormSet = inlineformset_factory(customer, order, fields=('product','status'), extra=7) CustomerOrderOwner = customer.objects.get(id=pkCrteOrder) formSet = OrderFormSet(queryset = order.objects.none(), instance=CustomerOrderOwner) if(request.method == 'POST'): print("post request detected") formSet = OrderFormSet(request.POST, instance=CustomerOrderOwner) if formSet.is_valid(): formSet.save() return(redirect('/')) else: print("formset was invalid") context = {'formSet': formSet} return(render(request, 'accounts/orderForm.html', context)) Brief explaination: From … -
Edited form not getting saved in django
