Django asking for instance instead of value
I have a django app with these models (only relevant fields): class Device(models.Model): serial = models.PositivewSmallIntegerField(unique=True, defeult=0000) …. class Conexion(models.Model): serial = models.ForeignKey(Device, to_field='serial', null=True, blank=True, on_delete=models.DO_NOTHING) …. When I try to assign a integer value to serial in Conexión, django asks for a Device instance. But this is wrong, because I have set to_field='serial'. I have exactly the same Foreign key in another model and it works ok. This is the exception: ValueError: Cannot assign "11": "Conexión.serial" must be a "Device" instance -
Is there any way to use the return value of custom python script to django template?
I'm trying to run a custom python script and return its value to template. The return function from custom script is returning value in the script but i can't use it in template. This is my custom script which returns the label value: def genre(f): K.clear_session() model = joblib.load('music/finalized_CNNmodel.sav') print(model.layers[0].input_shape) mel_spec(f) test_image=image.load_img(f'media/{f.file.name}.png', target_size=(256,256), color_mode='rgb') test_image=image.img_to_array(test_image) test_image=np.expand_dims(test_image,axis=0) result=model.predict(test_image) label = np.argmax(result) return label I'm calling this function through views as: def model_form_upload(request): documents = Document.objects.all() if request.method == 'POST': form = DocumentForm(request.POST, request.FILES) if form.is_valid(): print(request.FILES) newdoc = Document(file=request.FILES['file']) newdoc.save() print(newdoc.file.name) genre(newdoc) return render(request,'music/result.html', {'documents':documents,'form':form}) else: form = DocumentForm() return render(request,'music/result.html', {'documents':documents,'form':form}) This is my template: {% if genre.label == 0 %} CLASSICAL {% elif genre.label == 1 %} DOHORI {% else %} POP {% endif %} I expected to show the result in the template but the return value is not passing to the template. -

How to get cors to work properly with angular (apollo client ) and django/graphene
I am trying to build an application with python-graphene and django to persist data on the database side and using angular on the client side. I have developed both sides and they are working well independently, angular using the in-memory-web-api and graphene using insomnia (a postman style application for linux). To integrate them, I am trying to use apollo-angular. However, the request is returning a 404. I am fairly new to web development, so I might be missing something trivial. Searching online I found out that because the server is running on http://localhost:8000 and the application is running on http://localhost:4200, I needed to have CORS setup on the server side. I have followed the instructions on the manual: Install corsheaders via pip install django-cors-headers. Add corsheaders to INSTALLED_APPS. Add corsheaders.middleware.CorsMiddleware topmost at MIDDLEWARE. But still the error persisted. That is when I came across this thread and the answers seemed to be relevant. That is when I: Added CORS_ORIGIN_ALLOW_ALL = True and CORS_ALLOW_CREDENTIALS = True to settings.py at the server. Removed django.middleware.clickjacking.XFrameOptionsMiddleware from MIDDLEWERE. Added the withCredentials header to the request at the client side. Cleaned the browser cashed data and cookies. But still the error persisted. Here is my … -
How to display python variable values in Django template without using Models?
I'm new to Django and am facing this problem currently. I want to calculate the area and perimeter of a circle and post the result in the Django Template. I used a form to allow a user to input any number which will be considered as the radius. Using the POST method, it will process it and output me the area and perimeter (in views.py file).

Django unable to hide sensitive variables
I have hooked my app to Sentry, and I'm trying to check if I can prevent sensitive varaiables from being logged. Here's my code: @sensitive_variables('user', 'pw', 'cc') def get(self, request): user = "foobar" raise Exception(f"{user}") My expectation was the it would replace the value of user with stars (**********), according to the docs: https://docs.djangoproject.com/en/2.2/howto/error-reporting/#filtering-sensitive-information However, the exception printed out its actual value -- and the sentry logs reflected this. How do i get it to replace the value of sensitive information with stars? -

MQTT-Django. How can I implement it?
I´m trying to implement a Django-Mqtt system, but I´m a bit lost. I would like to update my models constantly with the data I receive from the topics. I´ve managed to update the model data with this function in views.py: def dhtDetail(request): member = request.user.userprofile listDHT = member.dht.all() for sensor in listDHT: topic = sensor.topic #This topic (sensor.topic) has temperature and humidity data m = subscribe.simple(topic, hostname="Broker IP", retained=False) mes = str(m.payload) mes = men.replace("'", "") mes = men.replace("b", "") mes = men.replace("Hum", "") mes = men.replace("Temp", "") mes = men.split(" ") sensor.temp = float(mes[3]) sensor.hum = float(mes[1]) sensor.save() member.dht.add(sensor) listDHT = member.dht.all() return render(request, 'web/dhtDetail.html', {'listDHT':listDHT}) Clearly, this only connects to broker and updates the data when "dhtDetail.html" is reloaded. How can I implement MQTT with Django to constantly update the models? -

Wagtail ModelAdmin: Does not hide widget label
I have written an own panel that utilizes the django modeladmin. The modeladmin is connected to another model via a foreign key, but I dont want the user to be able to change the foreign key relation, only the other data on the form. I have therefor tried to hide the widget via the panels argument on the model admin: panels = [ FieldPanel("event_detail", widget=HiddenInput), FieldPanel("title"), FieldPanel("content"), FieldPanel("send_time"), ] This handles the input field correctly in the modeladmin, but sadly I still see the label in the modeladmin, which will confuse my users. How can I make sure that not only the field is removed but also the label? -
AttributeError: module 'profile' has no attribute 'run'
So I have an extended User model (extended AbstractUser) called Profile. This was in a seperate app called "profiles". I was plugging in the standard login and realised it was looking for a "profile" app name as standard, so I renamed it (directories, code, DB schema) which I thought should work. app_name was actually already set to "profile" in apps.py, so didn't need to rename url references. No dice. I get the error in the title. So I removed all migrations (I'm at the stage where I can still do this OK :) ) and deleted the sqlite DB that I'm currently working with, thinking I'd just rerun the migrations and recreate everything.

Send AJAX request to Django view with vanilla JS
I'm trying to send a GET AJAX request to a Django view using vanilla JS. is_ajax() passes but I could not retrieve the request object properly. Here is my JS code. With/out JSON.stringify(data) doesn't work. document.querySelector('#testForm').onsubmit = () => { let data = {category : 'music'}; const request = new XMLHttpRequest(); request.open('GET', 'test/', true); request.setRequestHeader('X-Requested-With', 'XMLHttpRequest'); request.onload = () => { const data = JSON.parse(request.responseText); console.log(data); } request.send(data); return false; }); And here is my Django view: def test(request): if request.is_ajax(): print('Yes!') data = {'category': request.GET.get('category', None)} return JsonResponse(data) else: raise Http404 It prints Yes! to the terminal but I get back a {category: null} in the console. This JQuery code works and I get the expected {category: "music"} response: $.ajax({ url: 'cart/', type: 'GET', data: data, dataType: 'json', success: function (data) { console.log(data); } }); I'm wondering what I'm missing in the vanilla JS code or in my Django view. -
