Custom M2M validation in Django admin not displaying to user
I have a model where I need to validate that an m2m field and a regular field are exclusive. (i.e. you can only have one or the other, not both.) class EventFrequency(models.Model): weekdays = models.CharField(...) dates = models.ManyToManyField(...) Since one is an m2m, overriding the model save() doesn't work. (the model is saved, then m2m added) I was able to throw the error successfully in the admin class by overriding save_related(), but it doesn't display in the admin form. It is just a regular server error. class EventFrequencyAdmin(VersionAdmin, admin.ModelAdmin): model = EventFrequency filter_horizontal = ('dates',) def save_related(self, request, form, formsets, change): super(EventFrequencyAdmin, self).save_related(request, form, formsets, change) if form.instance.dates.exists() and form.instance.weekdays: raise ValidationError('Cannot select both dates and weekdays.') I am able to catch the error in an attempt to show it to the user by overriding changeform_view(). It appears to work well except for the redirect. form_url has no value, and is therefore ''. def changeform_view(self, request, object_id=None, form_url='', extra_context=None): try: return super(EventFrequencyAdmin, self).changeform_view(request, object_id, form_url, extra_context) except ValidationError as e: print('************* caught error *************') self.message_user(request, e, level=messages.ERROR) return HttpResponseRedirect(form_url) What am I doing wrong? -
Django 3.0: django-notifications giving error: "Notification.recipient" must be a "User" instance

How do you call a custom serializer update method in Django rest framework?
I am trying to make a simple API that takes in an audio file, reverses it, and stores them both. It can accept the file, and overwriting the perform_create() method I reversed it. But now I can't find a way to update the record with the reversed file. This is my viewset class SoundViewSet(viewsets.ModelViewSet): queryset = Sound.objects.all().order_by('id') serializer_class = SoundSerializer def perform_create(self, serializer): serializer.save() sound = Sound.objects.last() root = settings.MEDIA_ROOT.replace('/media','') root = root + sound.audio.url p = Path(root) clip = AudioSegment.from_wav(p) rev = clip.reverse() sound.reversedaudio = rev serializer = SoundSerializer(data=sound) serializer.is_valid() Sound.objects.filter(id=sound.id).update(reversedaudio=serializer.data.get('reversedaudio')) It is returning NULL values. I have to pass it through the serializer first because the audio file has to be parsed for JSON. I just can't seem to find a simple way to call a serializer update() like the perform_create(). I tried Sound.objects.filter(id=sound.id).update(reversedaudio=sound.reversedaudio) but its a viewset update, file gets uploaded un-parsed and is basically then garbage. Here's my serializer class: class SoundSerializer(serializers.HyperlinkedModelSerializer): class Meta: model = Sound fields = ('name', 'audio', 'reversedaudio') Can someone point out what I'm missing? P.s. I am using DRF for the first time and working under a deadline so I would prefer not having to define everything on my own and … -

How to limit requests to my API to authenticated users?
I am creating an API with Django and uploaded it to Heroku. Then I want to be able to make requests to this API from anywhere. However, I am wondering (since I am a beginner to Django) how I could add that authentication so that no one can come in and make HTTP calls. By the way, I am using the latest version of Django.

django-filters w/ authentication permsission
I am try to create a view where if you are an admin on the site, you can view all orders regardless of who placed the order. In addition, if you are not an admin, then you can only see the orders you have placed. Now, I have a view that does this: orders/views.py: @method_decorator(login_required(login_url='account_login'), name='dispatch') class OrderListView(ListFilteredMixin, ListView): model = Order template_name = 'orders/order/list.html' filter_set = OrderFilter queryset = Order.objects.all() def get_queryset(self): if self.request.user.is_staff: return self.queryset.all return self.queryset.filter(user=self.request.user) The problem is, if I include the "get_queryset" function in the OrderListView, my django-filters "filter_set" no longer works. I am not receiving any errors when trying to filter...its just doesn't do anything. Any help would be appreciated. Thanks! -

How do I display the data of my search query in an html template in django?
I'm writing a django app that lets you search for a movie using the Ghibli API. So far, it works and whenever I look for a movie it appears but only in the terminal.

Convert QueryDict in Django to an array of object

Django/Ajax: Why is my request.body empty when I send it via POST with Ajax?
I am trying to handle a button in my Django views without reloading the page using Ajax requests. I already managed to do something similar but when submitting a model formset. Two problems are arising: First, request.body in my view is empty (I get b'') and Django is also expecting a csrf token even when this request is not comming from a form submission. This is my HTML/JavaScript. I still have them together because I haven't made enough things work; will organize later.

Replacing items in a list in Django through a form
I have a python list with hundreds/thousands of strings: ['hello', 'good morning', 'evening everyone' ... ] I loop through these items on a Django page and in some circumstances, I need to show an input to allow the user to change the string. It looks something like this: <form method="post"> {% for item in list %} <p>{{ item }}</p> {% if certain_condition %} <input name="replace"> {% endif %} {% endfor %} </form> The user may leave all fields empty, fill all of them out, or anything in between. Now, when the form is posted, I need to create a new list (or replace the old list), in which those items that are sent in the POST are being replaced. However, I'm not totally sure what the best way is to engineer this. I'd like clean and efficient code, but my first doubt is how to convey in the POST which of the items is being replaced. Should I add another input that contains the position of the original item in the list? Or should I send the original name? Or is there a better way? To replace I'm thinking of using list comprehension, but also not sure if this is … -

AngularJs if statement in ng-href and collpase ng-href
I want to do a similar thing done here https://www.w3schools.com/bootstrap/tryit.asp?filename=trybs_collapsible2&stacked=h with a small change using angular js. Let's say I have a variable test, Now my href(Simple collapsible) will display only when the test has some string otherwise no href displayed. I tried below condition in my angular template: Simple collapsible [[test]] Note: I am actually having a condition like this https://django-angular.readthedocs.io/en/latest/template-sharing.html but it doesn't include how to collapse ng-href. Any help would be really appreciated. -
