How can I get converted data from a model and with validating still works in Serializer in a concise way?
I have a serializer class look like this: class ReceiverInfoSerializer(ModelSerializer): create_at = serializers.DateTimeField(read_only=True, format='%Y-%m-%d %H:%M:%S') change_at = serializers.DateTimeField(read_only=True, format='%Y-%m-%d %H:%M:%S') user_id = serializers.IntegerField(required=False) receiver_phone_num = serializers.SerializerMethodField() def get_receiver_phone_num(self, instance): secret_phone_num = get_encryption_phone_num(instance.receiver_phone_num) if instance.receiver_phone_num else None return secret_phone_num receiver_phone_num is also a model field. These are plain text form phone numbers store in db table. Now, I want to retrieve it with * replacing middle 4 digits. Like, from 18812345678 converting to 188****5678. And this is what get_receiver_phone_num does. But when I use this SerializerMethodField, the validating for receiver_phone_num becoming invalid, cause it is read-only. In that way, I have to make converting in to_representation method instead like below: def to_representation(self, instance): res = super().to_representation(instance) res['receiver_phone_num'] = get_encryption_phone_num( instance.receiver_phone_num) if instance.receiver_phone_num else None return res and I do not think it is convenient cause I have to override it. Do you have any other workaround about this, please show me. -

django-ckeditor: how to make carrige return insert a <br> instead of a new <p>?
In my CKEditor instances, I need ENTER to insert a <br> instead of a new <p> element, mainly because of the line separation.

Django channels with Spring Boot Websockets (StompSession) do not work
Hey there we want to use Django just to execute python code and use channels for the results. Implemented everything the websockets are not working as they should. If I try to send something from our Angular frontend to Django it works fine. And otherwise our Spring Boot StompSession Websockets work fine with other Spring Boot Applications and Angular. But Django and Spring Boot do not. What I can see from the Django server logs: WebSocket HANDSHAKING /ws/card-detection/ [127.0.0.1:53209] i'm in connect method WebSocket CONNECT /ws/card-detection/ [127.0.0.1:53209] i'm in receive method text_data: CONNECT This gets executed as soon as the websocket request comes in. The django consumer (without the prints that are logged above): class MyConsumer(WebsocketConsumer): groups = ["broadcast"] def connect(self): self.accept() def receive(self, text_data=None, bytes_data=None): self.send(text_data="Hello world!") def disconnect(self, close_code): pass From Spring Boot we send an base64 encoded image. But also everything else does not work. As you can see the text_data is just CONNECT. Spring Boot: StompSessionHandler sessionHandler = new CardDetectionStompSessionHandler(request, user, webSocketMessagingService); createStompClient().connect(djangoServiceWSPath, sessionHandler); } private WebSocketStompClient createStompClient() { WebSocketClient client = new StandardWebSocketClient(); WebSocketStompClient stompClient = new WebSocketStompClient(client); stompClient.setMessageConverter(new MappingJackson2MessageConverter()); return stompClient; } The stomp session handler to give you an idea how it looks. … -

How to read list in django template
Could someone shed a light to help me to solve this nested list problem in Django template. I come across a list as such summary = [['Summary 1 CODE018'], [['Directory/File Name', 'Result']], [[['dir/var1/file1.txt', 'pass'], ['dir/var2/file2.txt', 'pass'], ['dir/var1/file3', 'pass'], [[['null']]]] How do I loop the above list so that I can get a table such as the first index is the table title, index1 is the table title and the rest (except when is it null) is the table body? Please take note that the last item could be [[['null']]] or [[['null', 'Info on directory CODEA18']]] which should be skip when null is detected. Expected: Summary 1 CODE018 Directory/File Name Result dir/var1/file1.txt pass dir/var2/file2.txt pass dir/var3/file3.txt pass My faulty code as below <table id="myTable"> {% for list in summary %} <tr> <td> {{ list.0 }} </td> <tbody> <td> {{ list.0.0 }} </td> <td> {{ list.0.0.0 }} </td> </tbody> </tr> </table> -

I keep getting an error as shown belong and I don't know how to fix it. this is the models.py for the address model route_name = models.ForeignKey(Route, on_delete=models.CASCADE) name = models.CharField(max_length=30) city = models.ForeignKey(City, on_delete=models.SET_NULL, blank=True, null=True) area = models.ForeignKey(Area, on_delete=models.SET_NULL, blank=True, null=True) location = models.CharField(max_length=30, choices=LOCATION_CHOICES, default='NULL') username = models.ForeignKey(settings.AUTH_USER_MODEL, default=1, on_delete=models.CASCADE) make_initial_location = models.BooleanField() def __str__(self): return self.name def get_absolute_url(self): return reverse('address-detail', kwargs={'pk': self.pk}) this is the Address form in forms.py: class Meta: model = Address fields = ['route_name','name', 'city','area','location','make_initial_location'] def form_valid(self, form): form.instance.username = self.request.user return super().form_valid(form) this is the Address creation view in views.py, this is where i wrote the code for redirecting to address-detail, it shows me that the error is in return redirect('address-detail') : @login_required def AddressCreateVeiw(request): form = AddressCreationForm() if request.method == 'POST': form = AddressCreationForm(request.POST) if form.is_valid(): form.save() messages.success(request, f'Your address has been successfully created!') return redirect('address-detail') return render(request, 'blog/address_form.html', {'form': … -
Editing comments from a post: NoReverseMatch while trying to edit comment of a post
I am quite new to Django and I am trying to edit the comments for a specific post. However, I am getting an error while running the code. My guess is that it has to do with the url path or the post_detail html file(I tried multiple ways on fixing it, but could not get it to work). NoReverseMatch at /post/3c6f50b5-195a-4868-8704-b50c7b127813/ Reverse for 'edit_comment' with arguments '(33,)' not found. 1 pattern(s) tried: ['post/(?P<pk>[0-9a-f]{8}-[0-9a-f]{4}-[0-9a-f]{4}-[0-9a-f]{4}-[0-9a-f]{12})/comment/edit/$'] Models.py: class Post(models.Model): id = models.UUIDField( primary_key = True, default = uuid.uuid4, editable = False) ... class Comment(models.Model): post = models.ForeignKey( Post, on_delete=models.CASCADE, related_name='comments', ) comment = RichTextField() ... urls.py: urlpatterns = [ ... path('post/<uuid:pk>/comment/', AddCommentView.as_view(), name='add_comment'), path('post/<uuid:pk>/comment/edit/', EditCommentView.as_view(), name='edit_comment'), path('post/<uuid:pk>/comment/delete/',DeleteCommentView.as_view(), name='delete_comment'), ... ] views.py: class EditCommentView(LoginRequiredMixin, UserPassesTestMixin, UpdateView): model = Comment form_class = EditCommentForm template_name='blog/edit_comment.html' login_url = 'account_login' def test_func(self): obj = self.get_object() return obj.author ==self.request.user class DeleteCommentView(LoginRequiredMixin, UserPassesTestMixin, DeleteView): model = Comment template_name = 'blog/delete_comment.html' fields= '__all__' success_url = reverse_lazy('blog_home') login_url = 'account_login' def test_func(self): obj = self.get_object() return obj.author == self.request.user def form_valid(self,form): form.instance.post_id = self.kwargs['pk'] form.instance.author = self.request.user return super().form_valid(form) forms.py: class EditCommentForm(forms.ModelForm): class Meta: model = Comment fields = ('comment',) widgets = { 'comment': forms.Textarea(attrs={'class': 'form-control'}), } post_detail.html: {% if not post.comments.all … -
Remove file from S3 Bucket django-storages
I have a Django app that I am hosting on Heroku and the media files are served from AWS. I have a model that looks like this: class MyModel(models.Model): name = models.CharField(max_length=100) image = models.ImageField(upload_to="images/") def __str__(self): return self.name And I use a function inside views.py to delete the instance of the image from the model AND the image from the server. def delete_single_image(image): if image.image: image.image.delete() image.delete() This was working when I run it locally, but it doesn't delete the image from the S3 bucket when I host it on heroku. What can I do to remove it from there also? -
Django: dynamically append query results to context inside of view
I need to access models' data associated with one particular model (let's say model1). What is frustrating is that my database structure does not contain foreign keys or things to easily relate to model1. The underlying issue is that I can't figure away to manually replace the append method to add value:key pairs into the context dictionary. Here is what I have so far: @method_decorator(login_required, name='dispatch') class PostDetailalerte_trend2(LoginRequiredMixin,APIView, tables.SingleTableMixin, ExportMixin): def get(self, request): queryset = trend2.objects.all().values('reference') queryset2 = {} queryset3 = {} print(queryset) for object in queryset: queryset2.append(old_year2.objects.filter(Id = object['reference']).values('Qm3', 'Qm2', 'Qm1')) queryset3.append(demand_planning2.objects.filter(Id= object['reference']).values('ltplus1')) return render(request, 'detailstocktrend2.html', {'queryset': queryset, 'queryset2': queryset2, 'queryset3':queryset3}) ##how to replace the not working APPEND method?/ I have seen several example recommanding to manuall create the keys, however this is not an option because I cannot know in advance how big the dict will be. Any help or any alternative way to do that is welcome -
Run a function in Django after loading views
I want to run a python function when the user clicks a button, but I don't wanna run it before loading the template. For example in views.py def index(request): return render(request, "some_html.html") in some_html.html <form method="post"> <input type="button" id="run-button" value="RUN" name="run-button"> </form> And then when the users clicks the button "RUN", I wanna run a function, let's say doSomethingCool, how would it be? I'm wondering if it'd be like this on views.py def index(request): return render(request, "some_html.html") def doSomethingCool(request): if request.method == "POST" and "run-button" in request.POST: print("Some cool stuff") doSometingCool(request) Any ideas?
