Django - Filter objects from child class with parent class primary key passed in URL
I'm a newbie in Django and I'm trying to pass all the Posts made for each vehicle in a vehicle detail html page. My vehicles/models.py: *vehicles/models.py* class Vehicle(models.Model): TESLA = 'TESLA' MAZDA = 'MAZDA' VOLVO = 'VOLVO' VEHICLE_CHOICES = ( (TESLA, "Tesla"), (MAZDA, "Mazda"), (VOLVO, "Volvo"), ) owner = models.ForeignKey(User, on_delete=models.CASCADE) model = models.CharField(max_length=9, choices=VEHICLE_CHOICES, default=TESLA) def __str__(self): return self.model class Meta: db_table = "vehicles" My Posts models.py: *blog/models.py* from django.db import models from django.contrib.auth.models import User class Post(models.Model): date_posted = models.DateTimeField(default=timezone.now) author = models.ForeignKey(User, on_delete=models.CASCADE) vehicle = models.ForeignKey(Vehicle, on_delete=models.CASCADE, default=None ) def get_absolute_url(self): return reverse('post-detail', kwargs ={'pk': self.pk} ) class Meta: db_table = "chargehistory" I am already passing in a html file all the Vehicles for each User and now i would like to get all the posts made for each User's vehicle. *vehicles/views.py* class UserVehicleListView(ListView): model = Vehicle template_name = 'vehicles/vehicles.html' # <app>/<model>_<viewtype>.html context_object_name = 'vehicles' def get_queryset(self): return Vehicle.objects.filter(owner_id= self.request.user.id) class UserVehicleDetailView(DetailView): model = Vehicle *vehicles/urls.py* urlpatterns = [ path('vehicles', UserVehicleListView.as_view(), name='vehicle-list'), path('vehicles/<int:pk>', UserVehicleDetailView.as_view() , name='vehicle-detail'), ] urlpatterns += staticfiles_urlpatterns() Since i'm passing the vehicle primary key in the path, is there any way for me to filter the posts based on that key and pass it … -
Unexpected Keyword argument using formset_factory
I'm working on a project in which a teacher can add marks to his students, I want to use formset_factory so the teacher can add many marks at the same time, but I want a teacher to see only his students, and not the students who are not in his class. I got it when using a single form, but when I try to use the formset_factory, I get this error: init() got an unexpected keyword argument 'request' This is my working code in views: class AddNotaBlock(FormView): template_name='notas/insertar_nota.html' form_class= NotaCreateFormTeacher success_url= reverse_lazy('home') def get_form_kwargs(self): """ Passes the request object to the form class. This is necessary to only display members that belong to a given user""" kwargs = super(AddNotaBlock, self).get_form_kwargs() kwargs['request'] = self.request return kwargs in forms: class NotaCreateFormTeacher(ModelForm): def __init__(self, *args, **kwargs): self.request = kwargs.pop('request') super(NotaCreateFormTeacher, self).__init__(*args, **kwargs) usuario=self.request.user profe=Teacher_profile.objects.get(profesor=usuario) colegio=profe.colegio self.fields['Username'].queryset = Student_profile.objects.filter( colegio=colegio) class Meta: model = Nota fields = ('Username', 'nota', 'colegio') widgets= {'colegio':HiddenInput()} formset=formset_factory(NotaCreateFormTeacher, extra=2) when I use: form_class= NotaCreateFormTeacher Everything works (but only a form is displayed) If I use: form_class=formset I get the unexpected keyword argument error: init() got an unexpected keyword argument 'request' What I'm I doing wrong?

server returns list of tuples to an ajax request but back in the html I need to work on it and html(data) doesn't give a proper structure
I manage to send the ajax request to the server, and the server replies with a list of tuples or it could be a dictionary too, but back in the html that sent the request, this list or dict gets sort of turned into a string and I can't iterate or work on it. This is because of the html(data), but I don't know any other variant other than text(data) but that doesn't solve the problem. So, once I have sent that list or dict, how can I work on it (like doing iterations) I am using DJANGO. I simplify the code because this is what matters, suppose I already have a dictionary that I turn into a list: SERVER (VIEW FUNCTION) RETURNS: dictionary = { "key1": "value1", "key2": "value2" } lista = list(dictionary.items()) return HttpResponse(lista) Then back in the html code that sent the request, this results don't keep the nature of the list, but seems like a string HTML PAGE: ... .. datatype:'html' }).done(function(data) { $("#received_answer").html(data); }); // closing ajax group console.log(value); }); // closing the click function });// closing document ready </script> I get this: ('key1', 'value1')('key2', 'value2') -

how to filter a model in a listview

Iterate over CSV rows using pandas in a faster way
I'm trying to read a CSV file through file upload from html template, and iterating over the rows and creating model object. views.py @login_required def uploadStudents1(request): if request.method == 'POST': uploaded_file = request.FILES['document'] ext = os.path.splitext(uploaded_file.name)[-1].lower() if ext == '.csv': data_file = pd.read_csv( uploaded_file, parse_dates=['date_of_birth']) data_file.fillna('-', inplace=True) for _, row in data_file.iterrows(): Sem1Students.objects.create( fname=row['first_name'], lname=row['last_name'], reg_no=row['reg_no'], gender=row['gender'], birth_date=row['date_of_birth'], ) messages.success(request, 'Uploaded student details successfully!') return redirect('/students') else: messages.error(request, "Invalid file type. Please upload again.") return render(request, 'students/upload1.html') return render(request, "students/upload/upload1.html") However this process is really slow, it takes like 5-6 seconds to read and create 74 records. Is there any better way to do this, i.e make the process faster? -

Django middleware to check ios/android app version using request header
I have an app for both Android and iOS platforms which their backend is written with Django and Django-rest-framework . I've been asked to check header of requests are sent from Android/iOS apps which includes app version number and it should respond if it needs require to update the app or not. Because I have to check this for each request before it reaches the views, I guess I have to do it with the help of a middleware. Is there any middleware already written for this? Otherwise, how can I make a custom middleware for this purpose? -
