django celery cannot start worker
I am having an issue with starting up my celery worker for my django project. Thank you for giving any help here. I think I shut down the celery process inappropriately (ctrl+c first, and ran the "celery -A proj worker " command again before it was shut down completely). Since then I have never been able to start up my celery worker. It basically gives no response from the command line, not moving forward, no error, and nothing happens literally. It is just stuck there. I also tried to reinstall my celery and rabbitmq, but this doesn't help either. Does anyone know what could be wrong here? Thank you very much for your help. sen -

Django Form based on Form
I am writing my code based on the principle don't repeat yourself. I keep violating that rule because I am new to Django but this one should be straight forward. The code below is no problem for ModelAForm: model.py class ModelA(models.Model): id = model.AutoField(primary_key=True) name1 = models.CharField(max_length=100) name2 = models.CharField(max_length=100) ... right = models.BooleanField(default=True) class ModelB(models.Model): id = model.AutoField(primary_key=True) mod = model.ForeignKey(ModelA, on_delete=models.CASCADE) above30 = models.BooleanField(default=True) forms.py class ModelAForm(forms.ModelForm): class Meta: model = ModelA exclude = ['id'] class ModelBForm(forms.ModelForm): class Meta: model = ModelB exclude = ['id'] But this way I don't see the other fields of modelA in the ModelBForm. How can I do this? Thanks! -
Link JavaScript Button to Django Form
I have a JavaScript Function for showing fullcalendar. There I added a custom button (addEventButton) for adding new events: $('#calendar').fullCalendar({ header: { center: 'addEventButton', }, events: '/schedule/api/occurrences?calendar_slug=calendar', customButtons: { addEventButton: { text: '+', click: function() { var dateStr = prompt('Enter a date in YYYY-MM-DD format'); var date = moment(dateStr); if (date.isValid()) { $('#calendar').fullCalendar('renderEvent', { title: 'dynamic event', start: date, allDay: true }); } } } }); To get this new events into my django-model, where all events are stored, I've made a forms.py: class create_calendar_event(forms.Form): Title = ModelChoiceField(label='Title', queryset=Title.objects.all()) INPUT_FORMATS = ['%Y-%m-%d %H:%M'] start = forms.DateTimeField(input_formats=INPUT_FORMATS, widget=forms.DateTimeInput()) end = get_end_time(start) calendar = ModelChoiceField(label='Calendar', queryset=Calendar.objects.all()) How can I link this create_calendar_event form into the JavaScript addEventButton? -
How to query the number unique relations in Django
I have difficulties to create a more complex model query in Django. My model structure looks like this: date 1 - n cases case n - 1 employee employee n - 1 company What I want is to query the number of unique 'companies' used in all 'cases' at a specific 'date' (for other reasons 'date' is its own model in this case) in a method of the date model. -
Combining Ember REST Adapter with Django rest_framework ModelViewSet
I am creating an application that uses Ember and Django. For the backend of Django do I use rest_framework with the ModelViewSet as my view class. In the frontend with Ember do I use the RESTAdapter. My backend sends data back like this: { "id": 22, "name": "test", "startdate": "2019-01-01", "enddate": "2018-12-26" } while my frontend expects it like this: { "appointment": { "id": 1, "name": "test", "startdate": "2019-01-01", "enddate": "2018-12-26" } } I can't figure out how to make either end conform the other end in a nice and clean way. In the Django view class could I do this: def list(self, request): """Send all appointments.""" serializer = AppointmentSerializer(self.queryset, many=True) return Response({'appointment': serializer.data}) and it would work to get the appointments, but then I would have to alter all the functions like create, update, delete etc. I feel like there has to be a clean and better maintainable way to fix this issue. -

Validating reCAPTCHA v3 in Django
In reCAPTCHA V2, I could verify in the views.py itself. However in V3 I don't know how to proceed. Now I'm using it in development with 127.0.0.1. First I have generated the site key and the secret key. In settings.py I have added secret key, GOOGLE_RECAPTCHA_SECRET_KEY = 'my_secret_key_here' Then in my signup.html I have, <script src='https://www.google.com/recaptcha/api.js?render=my_site_key_here'></script> Unlike previous there is no < div > tag to add the checkbox. The script itself is rendering the recaptcha symbol in the side of my browser. My question is, How can I validate using grecaptcha.execute. Do I have to add the script with my site key to every page I want to protect from spam or is there any simple way -
