How to solve 'POST 401 Ajax Error' in the console of a deployed django website
I keep on getting an error like below in the chrome console whenever I click my "Place Order" button in my website. I have struggled with this for hours. Here is my error: POST https://{{mywebsitedomain}}/order/create_ajax/ 401 jquery-3.5.1.min.js:2 I have no idea why this error suddenly shows up after I uploaded my website on a hosting provider online.

Cannot deploy django app to strato hosting [closed]
Has anybody successfully deployed django app to strato (strato.de) web server? After some struggle I was able to install all dependencies as wall as npm and node. Basically I noticed that using strato with ssh is very limited. I am running gunicorn on my default wsgi file but when I try to reach my website from domain address, nothing happens. I noticed that there is apache installed on the machine but installing mod_wsgi via pip fails. -

Call Sync function outside consumer (Django Channels)
There are 2 kinds of django web server running, gunicorn(WSGI) and channels(ASGI) respectively. WSGI server is responsible for handling HTTP request and channels is responsible for websocket connections. There is an API on WSGI server that would run a SQL query, and then trigger sending message to a particular user via websocket. I called async_to_sync to wrap the channel_layer.group_send, but sometimes error occurrs. Here's the code def some_view(request): # database operations # ... channel_layer = get_channel_layer() async_to_sync(channel_layer.group_send)( group_name, { 'type': 'send_function', 'data': data }, ) Most of the time it works fine, however, sometimes RuntimeError "You cannot use AsyncToSync in the same thread as an async event loop - just await the async function directly." occurred. This happened because there is a running event loop in current thread. I think it's probably that django is reusing threads and each request would initialize an event loop. My first solution is to create event_loop for each request and then call loop.run_until_complete, but it cause another RuntimeError "Cannot run the event loop while another loop is running" Then I tried to check if there is running event loop before call create event loop, if an event loop is running, get the running loop … -
Django 400 Bad Request when run in production with gunicorn
I am getting a 400 error on all my pages when I moved my django app from one hosting service to another, the hosting service I moved to is Scalingo. My settings.py file: DEBUG = os.getenv("DEBUG") == "True" ALLOWED_HOSTS = [x.strip() for x in os.getenv("ALLOWED_HOSTS").split(",")] My env variables ALLOWED_HOSTS="my-app.osc-fr.scalingo.fr,.localhost,127.0.0.1,[::1]" DEBUG="False" I contacted customer support who have advised me that it must be a configuration issue with my app. All existing answers here I have found have advised to make sure the ALLOWED_HOSTS variable is correct, and I have already checked that it includes the required addresses according to the hosting platform's django-specific docs. -

How to write Django views (JSON apis) with statically typed arguments and responses?
In Java Spring, I can write down (simplified): List<Apple> fetchApples(Orange request) { ... } class Orange { int a; double b; String c; ... } class Apple { int d; double e; String f; ... } By doing this, I can be very sure that users of the API will only pass in some data like {a: 42, b: 1.2, c: "hello"}, instead of {a: "wtf", z: [1,2,3]}. However, in Django, I do not find any method to hint this. I have to use a = int(request['a']) to manually convert that parameter into type int and so on. This is even more troublesome when dealing with more complicated structs. Thus, how can I do something similar to Java Spring? I know Django/Python is not statically typed, but a type hint is better than nothing. Why I need this: Firstly, more typing is better for the code (more errors can be found at lint time). Secondly, and most importantly, I want to run code generator but that definitely requires some static typing hinting. For example, generate Dart/Flutter client of the Django server. -

How do I set a wildcard for CSRF_TRUSTED_ORIGINS in Django?
After updating from Django 2 to Django 4.0.1 I am getting CSRF errors on all POST requests. The logs show: "WARNING:django.security.csrf:Forbidden (Origin checking failed - https://127.0.0.1 does not match any trusted origins.): /activate/" I can't figure out how to set a wildcard for CSRF_TRUSTED_ORIGINS? I have a server shipped to customers who host it on their own domain so there is no way for me to no the origin before hand. I have tried the following with no luck: CSRF_TRUSTED_ORIGINS = ["https://\*", "http://\*"] and CSRF_TRUSTED_ORIGINS = ["*"] Explicitly setting "https://127.0.0.1" in the CSRF_TRUSTED_ORIGINS works but won't work in my customer's production deployment which will get another hostname. -
Django Model Calculated field as Database level?
I have the simplified model below : class Product(models.Model): name = models.CharField(max_length=50) price = models.FloatField() class Invoice(models.Model): product = models.ForeignKey(Product,on_delete=models.PROTECT) quantity = models.FloatField() @property def total(self): return self.quantity * self.product.price I would like to be able to process data analysis on my Invoices data. If i load my queryset to a list, the total property is missing : Invoice.object.all().values_list() Is there a way with django to calculate the property field as a database level ? So it would be easy to analyse from queryset (ideally i would like to load in dataframe) Thanks for the tips ! -

best way to create example project in a django plugin test suite
This may be a simple question, but I can't wrap my head around it. Given I make a Django plugin app, lets name it foo, which adds some database features, that other apps can use (e.g. models that must be inherited), and I want to add tests for that app. Structure: foo/ apps.py models.py tests/ test_foo_basic.py test_bar.py ... setup.py README.md ... The project is no full Django application, as it is an plugin app for others. So I need to create a fake Django project within the testing directory, with at least one app, which defines some models that inherit from foo.models.<some_model> and test it, right? Is that the only way? It seems a but much for me. If so, it's ok for me to give me the answer "it is so". And I'll accept ;-) If not, please tell me I am complicated and show me something easier, a pytest plugin etc.? For testing, I need a -

DRF & Next.js: Cookies are not stored in the browser only in the production environment
I'm working on a web app with DRF in the back and Next.js in the front. For some reason, only in the production environment, the JWT cookie from authentication is not saved in the browser.

How to format negative numbers in django-tables2?
I am looking for nice solution to make a simple subclassed NumericColumn for my tables, based on django-tables2. I started with that: class NumericColumn(Column): def render(self, value): return '{:0,.2f}'.format(value) It works great until I decided to make negative values red: class NumericColumn(Column): attrs = { 'td': { 'class': lambda value: 'text-danger' if value < 0 else '' } } def render(self, value): return '{:0,.2f}'.format(value) Code periodically fails with TypeError: '<' not supported between instances of 'str' and 'int', and it seems that lambda function receives already formatted value. I don't see a way to get an original value in record via accessor, and I don't think that it is nice to make a reverse conversion to Decimal for such comparison. Ok, I can test first character for '-', but it is too ugly. Please help. -

How to get all fields of related object Django
I have two models: class Checklist(models.Model): author = models.ForeignKey(User, null=True, on_delete=models.SET_NULL) client_name = models.ForeignKey(Client, on_delete=models.CASCADE, related_name='details') filedA = models.CharField(max_length=25, blank=True, null=True) filedA_Check= models.BooleanField(default=False) filedB = models.CharField(max_length=25, blank=True, null=True) filedB_Check= models.BooleanField(default=False) class Client(models.Model): client_filedA = models.CharField(max_length=25) client_filedB = models.CharField(max_length=25) client_filedC = models.CharField(max_length=25) Now I trying to change Client instance fields values via Checklist using following code: @login_required def create_order(request, pk): instance = get_object_or_404(CheckList, id=pk) form = myForm(request.POST or None, instance=instance) if form.is_valid(): form.save() messages.success(request, 'Test message') return get_PDF_order(request, pk) return render(request, 'templates/create_order.html', {'form': form}) And it's works but only once. Data saved and I get a pdf file with this data, but subsequent attempts do not change anything. The field value still the same. I'm guessing that it is because I working with the Checklist instance but not Client. So, my questions are: 1) How I can get an access to all Client fields (a queryset of all fileds) via Checklist? 2) Although my code is incorrect - why does it work (once)? I mean why does it save first time? Thank you all in advance! -

Inside this validation I have an error adding line if it doesn´t pass validation like this: class PostVacation(forms.ModelForm): class Meta: model = Vacation fields = ( 'fecha_inicio', 'fecha_fin', ) fecha_inicio = forms.DateField(widget = forms.DateInput(format='%d/%m/%Y',attrs={'type':'date','class': 'form-control'})) fecha_fin = forms.DateField(widget = forms.DateInput(format='%d/%m/%Y',attrs={'type':'date','class': 'form-control'})) def __init__(self, *args, **kwargs): super().__init__(*args, **kwargs) def clean_fecha_inicio(self): data = self.cleaned_data['fecha_inicio'] if data < timezone.now().date(): print(type(data)) self.add_error(None,"La fecha de inicio no puede ser anterior a hoy") return data Inside my template I try this: <div class="col-md-4 listados"> <form method="POST">{% csrf_token %} <div class="form-group"> {{ form.as_p }} {{ form.non_field_errors }} <p>Los campos marcados con * son obligatorios</p> <button type="submit" class="btn boton_generico">Guardar</button> </div> </form> </div> But it just returns empty Any help welcome
