How to reload Django context from JavaScript w/out redirect?
I am developing a dictionary application and a simple bookmark page where bookmarked definitions are displayed. I am using JavaScript to add/remove a definition to/from bookmarks through a button. The button works. However, when I am on the bookmarks page and I press it to remove a definition from my bookmarks, the definition stays there until I reload the page. I would like the definition to disappear as soon as I hit the button through JavaScript. I tried to remove the parentNode of my button (the div for definition) but it looks horrible, and that's not what I am looking for. I am now trying to send an AJAX request to my Django bookmarks view to re-load the context, but so far I haven't been able to do it. Can anybody help? Here is my Javascript code (the ? is where I am stuck): function toggleBookmark(event) { // Get definition id. let id = event.target.id.split("-")[1]; // Send AJAX request to bookmark view. $.get("/bookmarks/bookmark/" + id, function (data) { if (data.added) { alert('Definition added to your bookmarks.') event.target.innerHTML = 'Remove definition from your Bookmark'; } else if (data.removed) { alert('Definition removed from your bookmarks.') event.target.innerHTML = 'Add definition to your Bookmarks'; … -

Change Django self describing api
I built an api using django which has a user. class Client(models.Model): user = models.OneToOneField(User, on_delete=models.CASCADE, primary_key=True) name = models.CharField(max_length=100) address = models.CharField(max_length=100) phone = models.CharField(validators=[validate_phone_number], max_length=20) I am using ModelViewSet to automatically generate the crud methods. However, I add two new routes which are login and signup: class ClientViewSet(viewsets.ModelViewSet): queryset = models.Kindergarten.objects.all() serializer_class = serializers.KindergartenSerializer @action(detail=False, methods=['POST'], name='signup') def signup(self, request): return self.create(request) @action(detail=False, methods=['POST'], name='login') def login(self, request): serializer = serializers.UserSerializer(data=request.data) username = request.data['email'] raw_password = request.data['password'] user = authenticate(username=username, password=raw_password) login(request, user) return Response(serializer.data) Then I route like this : router = routers.DefaultRouter() router.register(r'client', views.ClientViewSet) My problem is when I open my documentation I get to fill field that I do not need : How can I better customize the self description view ?

Crispy Forms: Align dynamically
I add some forms to my page dynamically - I always start with a name field and add multiple others depending on a database entry in the data field: class ProductModelForm(ModelForm): class Meta: model = Product fields = ("name", "data") def __init__(self, user, *args, **kwargs): super(ProductModelForm, self).__init__(*args, **kwargs) user_layouts = models.Layout.objects.filter(user__id=user.id) all_fields = {} self.helper = FormHelper() self.helper.form_method = 'POST' HTML_SAVE = HTML(f"""<button type="submit" name="submit" value="save">save</button>""") NAME_FIELD = Column(Field('name'), css_class='form-row') self.helper.layout = Layout(NAME_FIELD) DATA = Field("data", type="hidden") for i in range(0,n): tmpField = Column(Field( ...), css_class=...) self.helper.layout.append(tmpField) self.helper.layout.append(HTML_SAVE) Now my problem is, that because of using column I get a new line for every entry - but I actually would like the forms to be aligned more space preserving. But I never know which kind of form I add - could be a MultipleChoiceField, a BooleanField or a simple CharField. Is there a way so cripsy will align the forms for me in the page? I could stop using Column but which other field benefits me most? -

Speed of the django website after deploying it on heroku
I have deployed a django website on herokuapp (using free tier without having to pay anything) for testing.Currently when the site opens it takes a bit more time to open than the time it takes to open on localhost(127.0.0.1:8000).Also the images take a bit more time to load.My concern is that if I upload it on a platform such as digital ocean or linode or aws will I get the website to load in the same time as it is loading on heroku or there will be a better performance . Or is it the problem with the coding that is making it load slower. If that is the case please tell me ways so that I can get my website to load faster. -

Django primary key prefix and length
I am looking to add a custom primary key to my models. Here is what i have so far. ticket_id = models.CharField(max_length=10, primary_key=True, editable=False) I basically want the primary key for each record to look like this, auto-incrementing from 001. AB001 AB002 AB003 AB004 How would I accomplish this? Many Thanks -
Django Session isn't getting updated appropriately
Stumbled upon the error message - The request's session was deleted before the request completed. The user may have logged out in a concurrent request, for example. This error is popping up when rendering a django template (narrowed down the error to the line - return render(request, {})). This process involves uploading a file, running view logic, and presenting the results to the user. It worked for a good many files and is throwing this error for one specific file. The view logic involves a bunch of django session updates. Suspected that this error could be due to the huge session size. Ironically though, the size of the session as I checked in the DB is 120 MB, which sounds reasonable. Can you walk me through the possible issues that could have led to this error? Thanks in advance! -
Can't send API Requests from python code hosted on AWS Lightsail instance
I have a django website that is hosted on an AWS Lightsail. I am trying to add in a Speech to text tool in it. I have tried Google Cloud Speech to text as well as Microsoft Azure Speech to text APIs for this purpose and have used sample code from their websites. The code works fine when i'm running it on my localhost, but the same code does not work when hosted on that AWS Lightsail instance. There is no error, the reponse just never comes and the status stays on "pending.." Is there any log i can check for an error? Or is there any additional step required? Thank you in advance. -
Dynamic inheritance from Model
I have a Photo-Model that helps me achieve storing each image as a thumbnail aswell: class Photo(models.Model): image = models.ImageField(upload_to=upload_path, default=default_image) thumbnail = models.ImageField(upload_to=upload_path_2, editable=False, default=default_image_2) id = models.UUIDField(primary_key=True, default=uuid.uuid4, editable=False) Now I have another Model, lets call it User, which inherits from Photo: class User(Photo): id = models.UUIDField(primary_key=True, default=uuid.uuid4, editable=False) Now lets say there are multiple classes inheriting from Photo and depending on the inheriting class, I want to set another upload_path and default_image. How Do I achieve that? Can I somehow use the constructor? Thanks in Advance! -
How can I solve this problem in update crud in Django?
Well, I've been trying to solve this problem for days, at the time of performing the update crud, the form doesn't make me valid and the modified records aren't saved. Next I will show you how my code is in each module: views.py def modificarcurso(request,id): curso = Curso.objects.get(id=id) curso = CursoForm(request.POST, instance=curso) if curso.is_valid(): curso.save() return redirect("/mostrarcursos") return render(request, 'mostrarcursos.html', {'curso': curso}) forms.py class CursoForm(forms.ModelForm): class Meta: model = Curso fields=['docente','anio','paralelo','jornada'] models.py class Curso(models.Model): docente= models.ForeignKey(Docente,on_delete=models.CASCADE) anio = models.IntegerField(default=1) paralelo = models.CharField(max_length=1) jornada = models.CharField(max_length=20) user = models.CharField(max_length=100) user_mod = models.CharField(max_length=100) created = models.DateTimeField(auto_now_add=True) updated = models.DateTimeField(auto_now=True) estado = models.IntegerField(default=1) # 1 es activo y 2 es eliminado class Meta: db_table ="Cursos" verbose_name ="Curso" verbose_name_plural ="Cursos" def __str__(self): return self.paralelo + ' ' + self.jornada Well, and in the html code the form is created where the records are entered with the name of each field.
