how to gracefully prevent specific instance from being deleted
I have a Django application that has a model like this: class Foo(models.Model): name = models.CharField(max_length=100) I have a specific instance in this model that it's name is 'bar' (for example) and I want to prevent this instance from being deleted. I've created a signal receiver like this: def protect_foo_bar(sender, instance, using, **kwargs): if instance.title != 'bar': pass else: raise ProtectedError(protected_objects=instance, msg='You cannot delete this object') and I've connected this receiver to pre_delete signal like this: pre_delete.connect(receiver=protect_foo_bar, dispatch_uid='protect_foo_bar_signal', sender='app_name.foo') When I try to delete this specific object from Django's admin panel, it returns an exception. Is it possible to force the admin panel to show an error like you cannot delete this object and not returning an exception to the user? -
Object of type 'A' is not JSON serializable
I've the following get_or_create method. class LocationView(views.APIView): def get_or_create(self, request): try: location = Location.objects.get(country=request.data.get("country"), city=request.data.get("city")) print(location) return Response(location, status=status.HTTP_200_OK) except Location.DoesNotExist: serializer = LocationSerializer(data=request.data) if serializer.is_valid(): serializer.save() return Response(serializer.data, status=status.HTTP_201_CREATED) else: return Response(serializer.errors, status=status.HTTP_400_BAD_REQUEST) def get(self, request): return self.get_or_create(request) def post(self, request): return self.get_or_create(request) This works fine for creating a new location, However if the location exists, I get the following error, TypeError: Object of type 'Location' is not JSON serializable [16/Mar/2018 10:10:08] "POST /api/v1/bouncer/location/ HTTP/1.1" 500 96971 This is my model serializer, class LocationSerializer(serializers.ModelSerializer): id = serializers.IntegerField(read_only=True) class Meta: model = models.Location fields = ('id', 'country', 'city', 'longitude', 'latitude') What am I doing wrong here -
Graphene Django DjangoFilterConnectionField with nested filters
I'm trying to achieve the following using graphene-django's DjangoFilterConnectionField: { allUsers(username_Icontains: "abc") { edges { node { id demographics (name_Icontains: "xyz") { id name } } } } } I know that in graphene django, it's possible to have nested filtering using graphene's List But I'm not sure if I can work this out using DjangoFilterConnectionField. I have the following graphene (relay) schema: class UserNode(DjangoObjectType): class Meta: model = User interfaces = (Node,) filter_fields = { 'username': ['exact', 'icontains', 'in'], } class DemographicNode(DjangoObjectType): class Meta: model = Demographic interfaces = (Node,) filter_fields = { 'name': ['icontains'], } class Query(ObjectType): user = Node.Field(UserNode) all_users = DjangoFilterConnectionField(UserNode) demographic = Node.Field(DemographicNode) all_demographics = DjangoFilterConnectionField(DemographicNode) In the docs it's suggested to introduce each filter on the connected node as well. So it would be like this: class UserNode(DjangoObjectType): class Meta: model = User interfaces = (Node,) filter_fields = { 'username': ['exact', 'icontains', 'in'], 'demographic__name': ['icontains'] } But I think there must be a better way to do this since I have to do this for more than 20 nested Nodes. -
How to make join using 2 foreign keys in django without raw query?
I have two seemingly unrelated tables that have unique pair of same foreign keys: class Car name = models.CharField() color = models.ForignKey(Color) driver = models.ForgnKey(User) class Meta: unique_together = (('color', 'driver'),) class Bicycle name = models.CharField() color = models.ForignKey(Color) driver = models.ForignKey(User) class Meta: unique_together = (('color', 'driver'),) For some reason I want to get query that have access to both of them. Simply to avoid querying in loop as the page is already complex. I can make raw query: query = Car.objects.raw( '''SELECT * from car INNER JOIN bicycle ON car.color_id = bicycle.color_id AND car.driver_id = bicycle.driver_id''' ) For compatibility reason I want to avoid raw query as it does not work in django admin panel and probably other places. Is there a way of making that query so the end result give me new column: car_query = Car.objects.something( Bicycle, join_with=('color', 'driver'), newfield='bicycle') print(car_query[0].bicycle.name) and is not a raw query: car_query.order_by('created') I have tried something like that: query = Car.objects.select_related('color').prefetch_related( Prefetch('color__bicycle_set', queryset=Bicycle.objects.filter(driver=F('driver')), to_attr='bicycle') ) But of course F('driver') relates to current queryset not the Car. Is this idea wrong? What should I do instead? -
Django Model form changing a field instance type on submit?
I have created a model form whereby I have overwritten and changed a foreign keys instance type so I could filter the list of options by site. However on submit of the form I need to change it back to its original instance type, which I though would be done on form save, but when I print out the save I do not see any output in console. it seems the error occurs before save? forms.py class CircuitSubnetForm(forms.ModelForm): class Meta: model = CircuitSubnets fields = ['circuit', 'subnet',] def __init__(self, *args, **kwargs): site_id = kwargs.pop('site_id', None) self.is_add = kwargs.pop("is_add", False) super(CircuitSubnetForm, self).__init__(*args, **kwargs) self.fields['subnet'].queryset = DeviceSubnets.objects.filter(device__site_id=site_id) self.fields['subnet'].label_from_instance = lambda obj: '{} - {}{}'.format(obj.device.hostname,obj.subnet.subnet,obj.subnet.mask) views.py class AddCircuitSubnet(CreateView): form_class = CircuitSubnetForm template_name = "circuits/circuit_subnet_form.html" @method_decorator(user_passes_test(lambda u: u.has_perm('circuits.add_circuitsubnet'))) def dispatch(self, *args, **kwargs): self.site_id = self.kwargs['site_id'] self.circuit_id = self.kwargs['circuit_id'] self.site = get_object_or_404(Site, pk=self.site_id) self.circuit = get_object_or_404(Circuit, pk=self.circuit_id) return super(AddCircuitSubnet, self).dispatch(*args, **kwargs) def save(self, commit=True): form = super(AddCircuitSubnet, self).save(commit=False) print(vars(form)) form.subnet = Subnet.objects.get(id=form.subnet.subnet.id) form.save() return form error: Cannot assign "<DeviceSubnets: DeviceSubnets object>": "CircuitSubnets.subnet" must be a "Subnet" instance. -

How to run travisCI using Django testing framework
I have a Django project that I'm building using TravisCI which is supposed to be running the test class I have. For some reason, when the build runs, it succeeds, but the output of the job says that 0 tests were run: I was originally using the command python manage.py test to run the build, but for some reason, it didn't seem to be working so I then ran the command python src/manage.py test FileUploadTestClass.test_uploaded_file but this results in an import error for the test class.

Ordering a list of querysets by latest record
I'd like to implement a private messaging function in Django, where a member can see his/her messages in one page, separated as conversations. The conversation with the most recent message sent or received by the member should appear on top. What I tried: all_messages = Message.objects.filter(Q(sender=member) | Q(receiver=member)) other_members = all_messages.values_list("sender", flat=True).distinct() conversations = [] for sender in other_members: if sender == member.id: try: conversation = all_messages.filter(sender=member).exclude(receiver__in=other_members) conversations.append(conversation) except: continue else: conversation = all_messages.filter(Q(sender=sender, receiver=member) | Q(receiver=sender, sender=member)) conversations.append(conversation) The problem here is that when the member receives a new message, related conversation goes up; but when he sends a new message, conversation order doesn't change. To sum up, how can I sort properly the conversations by the most recent last message in them? Thanks! -

Django select 2 multiple select slow load

Count of related entities over two ManyToMany relations to the same Model in Django
Given roughly these two models: class Person(models.Model): name = models.CharField() class Resource(models.Model): people_contributing = models.ManyToManyField( Person, related_name='resouces_contributing_to' ) people_involved = models.ManyToManyField( Person, related_name='resources_involved_in' ) For all persons I want to get the count of resources he/she is either contributing to OR involved in. I tried the following: resources = Resource.objects.all() participations = Person.objects.filter( Q(resouces_contributing_to__in=resources) | Q(resources_involved_in__in=resources) ).annotate( count=Count('id') ).values('pk','name','count').order_by('-count') print(participations) This gives me a list of tuples like this: [ # (id, name, count) (1, 'John Doe', 12), (2, 'Jane Doe', 5), (3, 'Donald Trump', 3), ] However if a person is both contributing and involved the resource will be counted twice because the resource will be joined twice to the person table. What I want is to join the resource in an XOR manner. How do I have to change my queryset to prevent this? I am using postgresql and Django 1.11. -
Django admin custom ArrayField widget
The current admin widget for ArrayField is one field, with comma as delimiter, like this (text list): This isn't ideal because I would have longer texts (even 20 words) and contain commas. I could change the delimiter to be something else but that still doesn't help with unreadable content in admin. What I would like is having a list of fields, that I can alter in admin. Something similar to the following image I could use another table to solve this, but I wonder if it's possible to solve it this way. -
Want to achieve searching function in django admin page for multiple tables
I am currently working on django 2.0.2 admin page. I have three tables, which are 'metabolites', 'gene' and 'reactions.'

A typically reaction actually involved more than two metabolites. What I want to do is, create a search field on the admin page(not the page of each class), and when I type in the reaction id, the searching result can display the reaction and all the involved metabolites, and when I … -

CSRF protection when not using forms to submit data
I have a list (that is forms in a formset) of files and for each item I have a button that can delete these files and their corresponding database records. Currently I am using an AJAX/JQUery call to achieve this. The button does not submit some kind of form but rather makes a POST request via AJAX ' directly' and I am wondering whether or not this is a safe way to do this w.r.t. CSRF? I have tried a number of things like adding the CSRF token to the header as per the documentation and using the @csrf_protect decorator. The function works and doesn't throw any errors but I'm not sure whether this is because the CSRF check are comming through or whether they simply never take place. When I look at my request.POST the CSRF-token is not listed, which is the case when I use a standard form approach. views.py @csrf_protect def delete_file(request): if request.method == 'POST': file_id = request.POST.get('file_id') try: SFile.objects.get(FILE_ID=file_id).delete() except: file_id = 0 return JsonResponse({'file_id':file_id}) raise Http404 AJAX/JQuery $('#file-list').on('click','.delete-file-button', function(event){ event.preventDefault(); var file_id2 = $(this).attr('id') var post_url = $(this).attr('data-url'); form_data = {file_id: file_id2} var csrftoken = getCookie('csrftoken'); $.ajaxSetup({ beforeSend: function(xhr, settings) { if (!csrfSafeMethod(settings.type) && …
