Multiple model instance django rest-framework
I was trying to find a way to create multiple objects with one API request in a django-rest based API. I found many answers to that and I came up with overriding ViewSet.get_serializer method as follows def get_serializer(self, *args, **kwargs): data = kwargs.get('data', None) if data: kwargs['many'] = isinstance(data, list) return super().get_serializer(*args, **kwargs) I also overrided serializer.to_representation in order to add some useful data to representation. Problem is that doing that when I create a single object per request everything's fine, but when I try to create multiple objects I get errors in serializer.to_representation method. I tried to debug the error and seems that when serializer is initialized with many=True instance passed to serializer.to_representation is a OrderedDict rather than the actual instance, so I cannot access properties of the instance like related fields, etc. def to_representation(self, instance): if self.context['request'].method == 'POST': print(type(representation), type(instance)) return super().to_representation(instance) This will output <class 'collections.OrderedDict'> <class 'main.models.Expenditure'> as expected for single object post request but for multiple object (which still are correctly created) requests output is more complex. <class 'collections.OrderedDict'> <class 'main.models.Expenditure'> <class 'collections.OrderedDict'> <class 'main.models.Expenditure'> <class 'collections.OrderedDict'> <class 'collections.OrderedDict'> <class 'collections.OrderedDict'> <class 'collections.OrderedDict'> in this example I tried to create two objects. The second … -
Django async view - how do I know its running async?
I can create an async view and inquire as to whether the method thinks it's a coroutine, and it is. However, looking at the stack it looks like my view is being called by asgiref's SyncToAsync. I am using Gunicorn with Uvicorn worker and an asgi.py script that starts with: from channels.routing import get_default_application channel_layer = get_default_application Plus, I am trying to discover if any of my middleware is running sync or even with a (forced) sync middleware I am not hitting (logger.debug('Synchronous %s adapted.', name)) Makes no sense. -

Difference between hosting Postgresql database on Railway or on AWS/Azure
I'm working on a django application I need to put online. For now I've only been working on personal projects that I never deployed. Searching for the best solutions, I found that Railway seems to be the easiest choice, and that I can even host the app and the database on it (and even the static files!). I don't know so much about databases, that's why I wonder if there are differences between hosting everything (the code + the database) on Railway or hosting the code on Railway, and connect it to a database hosted on AWS, Azure etc... It seems "too easy" for me to be possible to do that. Maybe the databases on Railway are great only for small usages ? I didn't find anything on the internet comparing those services and talking about the possible limits of Railway. Thanks a lot in advance for your help. -

Django function view rewriting to Class View UpdateView problem with Multiple Forms
Im trying to rewrite my whole app from function views to class views. Right now Im struggle with UpdateView I know that it can only accept one parameter of FORM. But I wonder after rewriting the code from topics (like mine) how to do it correctly and make it works. And Does it make sense to interfere with the intentions of the Django Developers? Or just leave this view as a view function? This how its looks right now views.py @login_required def edit_user_info(request): user = get_object_or_404(User, id=request.user.id) user_profile = get_object_or_404(UserProfile, profile=request.user) if request.method == "POST": user_form = UserForm(request.POST, instance=user) profile_form = UserProfileForm(request.POST, instance=user_profile) if user_form.is_valid() and profile_form.is_valid(): user_form.save() profile_form.save() messages.success(request, "Your profile is updated successfully") return redirect(to="profile") else: user_form = UserForm(instance=user) profile_form = UserProfileForm(instance=user_profile) context = { "user_form": user_form, "profile_form": profile_form, } return render(request, "web/update_user_info.html", context) forms.py class UserForm(forms.ModelForm): email = forms.EmailField(required=False,label="Updated email address if different", widget=forms.TextInput(attrs={'class': 'form-control'})) class Meta: model = User fields = ("email",) class UserProfileForm(forms.ModelForm): class Meta: model = UserProfile fields = ("about_user","user_photo",) and what I would like to make with UpdateView or other class View MultiModelFormView, TemplateView Also, I would like to leave the auto filled with forms, with user data class EditUserView(MultiModelFormView): form_classes = { … -

Trying to find a good example to create a html button in django to run a python function and display result
I've trying for a while now to learn django mostly for my own curiosity. My current goal is to have an button on screen that when pressed does some simple python function at first. Something like display a string value or a random number on the screen. I've found some examples but they're not helping my understanding of the problem. Most examples have been building like buttons or similar. I've tried looking into ajax calls for python but I can't seem to find writeups that help me with the basics and any video tutorials I find on this topic there is a language barrier which is not helping me learn. Sorry for asking probably a basic question. -

Django REST Framework pagination changing model ordering
For some reason when I run paginate_queryset(queryset) the ordering changes, and is not the order I want. I have the model: class MyModel(models.Model): name = models.CharField(max_length=100) history_date = models.DateTimeField() class Meta: managed = False db_table = 'myapp_historicalmymodel' ordering = ("-history_date",) With the ordering field set. Then I have an extra action in a ViewSet: class MyModelViewSet(viewsets.ModelViewSet): serializer_class = MyModelSerializer permission_classes = [permissions.IsAuthenticated] queryset = MyModel.objects.all() @action(detail=False, methods=['get'], url_path='history', url_name='history') def history(self, request): items = HistoricalMyModel.objects.all() print(items) # FIRST PRINT page = self.paginate_queryset(items) print(page) # SECOND PRINT if page is not None: serializer = HistoricalMyModelSerializer(page, many=True, context={'request': request}) return self.get_paginated_response(serializer.data) serializer = HistoricalMyModelSerializer(items, many=True) return Response(serializer.data) The first print prints out items in the configured order, using ordering = ("-history_date",), like: <QuerySet [<HistoricalMyModel: HistoricalMyModel object (4)>, <HistoricalMyModel: HistoricalMyModel object (3)>, <HistoricalMyModel: HistoricalMyModel object (2)>, <HistoricalMyModel: HistoricalMyModel object (1)>]> There you can see the order 4,3,2,1. But the second print prints items out in some default Postgres order it seems: [<HistoricalMyModel: HistoricalMyModel object (3)>, <HistoricalMyModel: HistoricalMyModel object (4)>, <HistoricalMyModel: HistoricalMyModel object (1)>, <HistoricalMyModel: HistoricalMyModel object (2)>] There you can see the order 3,4,1,2. Why is it changing the order of items after running self.paginate_queryset(items)? -

Django Imagekit I/O operation on closed file
I'm using Imagekit to resize pictures on a website i'm developing with Django, I've used Imagekit before without any issues but I have a strange problem. I am using S3 for Media/Static files. When I upload an image in admin and refresh the template serving the images i get ValueError at / I/O operation on closed file error page. Then if I refresh the page it loads fine without a problem. I am using an ImageSpec field to resize images and using {{ image.thumbnail.url }} in my template. I am very much a beginner with Django so looking for some direction. Why will it work on a page reload and not when initially uploaded? Here are the relevant fields in my model. class Media(models.Model): image = models.ImageField(upload_to="media") thumbnail = ImageSpecField([Adjust(sharpness=1.1), ResizeToFill(800, 650)], source='image', format='JPEG', options={'quality': 100}) -

Django Python - Can`t install fixtures in test database

Website creates a new non-existent webpage after I visit website/class_id
My website creates a new non-existent website, after I visit my website/näytä_luokka/# (also, class_id). If I try to go to a page that is in the same urls.py file, I get an error because it tries to find a page website/näytä_luokka/luokat instead of going to website/luokat. This happens through navbar. If I try to go to a link that is in another urls.py, everything works fine. Switching from /luokat to other pages works also fine. I am using django to create website. So, here's a couple examples from my urls.py from django.urls import path from . import views urlpatterns = [ path('näytä_luokka/<luokka_id>', views.näytä_luokka, name="näytä-luokka"), path('luokat', views.kaikki_luokat, name="luokat"),' ] and .views def näytä_luokka(request, luokka_id): luokkalistaus = luokka.objects.get(pk=luokka_id) return render(request, 'tietokanta/näytä_luokat.html', {'luokkalistaus': luokkalistaus}) def kaikki_luokat(request): luokkalista = luokka.objects.all().order_by('nimi') return render(request, 'tietokanta/luokat.html', {'luokkalista': luokkalista}) ** the navbar.** </li> <li class="nav-item"> <a class="nav-link" href="luokat">Luokat</a> </li> I tried adding / after id number, but id didn't do anything. Thank you if you can help me figure this out.
