with regard to form.save(commit=False), what am I missing?
As explained in many posts like the following: Why do we use "form.save(commit=False)" in Django-views? "The main use case is if you have a ModelForm that doesn't contain all the required fields of a model. You need to save this form in the database, but because you didn't give it all the required fields, you will get an error.." which is all good and dandy but why not just complete all the instance fields and then call the regular save? In the bellow example: # Creates a Dog class with all fields as mandatory: class Dog(models.Model): name = models.CharField(max_length=50) race = models.CharField(max_length=50) age = models.PositiveIntegerField() # Creates a ModelForm with only name and age: class DogForm(forms.ModelForm): class Meta: model = Dog fields = ['name', 'age'] # In your view use this form: def dog_view(request): ... form = DogForm(request.POST or None) # If the form is valid we need to add a race, otherwise we will get an error: if form.is_valid(): dog = form.save(commit=False) # Define the race here: dog.race = 'Labrador retriever' # And then do the regular save to push the change in the database: dog.save() ... why not just say: form = DogForm(request.POST or None) # Define the … -

Django import-export import foreign keys that do not exist

Django customize validation error message
I have a following serializer definitions that validate request payload: # diagnosis serializer class ICD10Serializer(serializers.Serializer): icd_10 = serializers.IntegerField(required=True, allow_null=False) class DetailsSerializer(serializers.Serializer): diagnosis_details = ICD10Serializer(many=True) class ChartUpdateSerializer(serializers.Serializer): diagnosis = DetailsSerializer(many=True) Its usage: payload = ChartUpdateSerializer(data=request.data) if not payload.is_valid(): raise serializers.ValidationError(payload.errors) This throws validation error message in the following format: { "diagnosis": [ { "diagnosisDetails": [ {}, <- valid {}, <- valid {}, <- valid {}, <- valid { "icd10": [ "This field may not be null." ] } ] } ] } Here {} is also shown for valid ones. Can we simply raise validation error for invalid ones? Or better even if we can know which field and the message so custom message can be generated. -

Django Redirect followed by database lookup
I have an authenticated user that is signed into a webpage Page1.html on this page I want to create redirect the user to another page that matches a particular property that the user has in their user role. I managed to get the part working that redirects the user to that webpage, but I know I am going to be faced with having many users so it will take a while for searching each user that is why I want the second redirect to occur on the second html page. My thoughts are that I use the manipulation of the post to the redirect of the first page Page1.html, and have Page1.html have a please wait till redirected to the final page that they will be using. I was reading this question but it did not really answer my question: Django - show loading message during long processing -

Writing Django Func() Expression with multiple parameters and specify the order
I'm using Func() Expressions to use this answer and compute the difference between two dates in business days: class BusinessDaysBetween(Func): """Implementation of a Postgres function to compute the working holidays between two fields.""" template = """ (SELECT COUNT(*) FROM generate_series(%(expressions)s, interval '1 day') s(day) WHERE EXTRACT(DOW FROM s.day) NOT IN (0, 6)) """ arity = 2 output_field = IntegerField() However, I am having problems with the formatting of Date and DateTime.

How to update large amount of records in chunks?
I have models: class Partner(models.Model): sap_code = models.CharField(max_length=64, null=True, blank=True, verbose_name='sap id', default=uuid4) # another fields class DeficienciesAct(models.Model): partner = models.ForeignKey('partners.Partner', null=True, on_delete=models.CASCADE) sap_code = models.CharField(max_length=64, null=True) # another fields Data: Partner: id sap_code 1 123 2 124 ... ... DeficienciesAct: id partner_id sap_code 1 null 123 2 null 333 ... ... ... 500000 null 421 Let's imagine that in DeficienciesAct there are 500 000 records. Not all DeficienciesAct.sap_code can be in Partner.sap_code. So I need to update field DeficienciesAct.partner_id by DeficienciesAct.sap_code. DeficienciesAct.sap_code is equal to Partner.sap_code. For that I developed a script: DeficienciesAct.objects.filter( partner__isnull=True, sap_code__in=Subquery(Partner.objects.values_list("sap_code")) ).annotate( new_partner_id=Subquery( Partner.objects.filter( sap_code=OuterRef('sap_code') ).values('id')[:1] ) ).update(partner_id=F("new_partner_id")) Well that works. But I'm afraid that huge amount of records can affect a database (postgres). Is there any way to do the task in chunks? -

Custom ASGI worker metrics with OpenTelemetry
Is it possible to create custom open telemetry metrics to calculate the average time a request stays queued in ASGI before execution and also the average queue size per worker? Or if it is not possible by worker just in general in the ASGI server. I tried searching on the internet but I didn't found any example of this use case. ChatGPT suugested me to create a middleware and do it like this: import time from starlette.middleware.base import BaseHTTPMiddleware from opentelemetry import metrics # Create a Meter meter = metrics.get_meter_provider().get_meter("asgi.queue") # Define a histogram for queue time queue_time_histogram = meter.create_histogram( name="asgi.queue_time", description="Time requests spend in the ASGI queue", unit="ms", ) class QueueTimeMiddleware(BaseHTTPMiddleware): async def dispatch(self, request, call_next): request.state.queue_start_time = time.perf_counter() # Request received response = await call_next(request) queue_time = time.perf_counter() - request.state.queue_start_time queue_time_histogram.record(queue_time * 1000) # Convert to milliseconds return response However I am little suspicious about this snippet and don't know if this is exactly what we want. Does anyone have any advice on this case? -

When I'm trying to insert a html code using "Source Edit" feature, it doesn't apply any style and transforms automatically after clicking "Source" button again into this: I already tried the GeneralHtmlSupport from documentation: https://ckeditor.com/docs/ckeditor5/latest/features/html/general-html-support.html My ckeditor config looks like this ClassicEditor.create( editorEl, config, { plugins: [GeneralHtmlSupport, SourceEditing, Undo, Alignment, Image, ImageResizeEditing, ImageResizeHandles], htmlSupport: { allow: [ { name: /.*/, attributes: true, classes: true, styles: true } ] }, image: { resizeUnit: "%", styles: { options: [ { name: 'Resize', title: 'Resize', className: 'Resize' }, ] }, }, htmlSupport: true, allowedContent: true } ).then(editor => { const textarea = document.querySelector(`#${editorEl.id}`); editor.model.document.on('change:data', () => { textarea.value = editor.getData(); }); if (editor.plugins.has('WordCount')) { const wordCountPlugin = editor.plugins.get('WordCount'); const wordCountWrapper = element.querySelector(`#${script_id}-word-count`); wordCountWrapper.innerHTML = ''; wordCountWrapper.appendChild(wordCountPlugin.wordCountContainer); } editors[editorEl.id] = editor; if (callbacks[editorEl.id]) { callbacks[editorEl.id](editor); } }).catch(error => { console.error((error)); }); editorEl.setAttribute('data-processed', '1'); }); window.editors = editors; -
Django: How to natural sort a QuerySet with Postgres and SQLite
I have the following model: from django.db import models class VersionInfo(models.Model): version = models.CharField("Version", max_length=16) # 3-digit version like "1.2.3". I have to natural sort the QuerySet by the 3 parts of "version" when rendering a django_tables2 table. I already tried things like this, but it doesn't sort like expected: from django.db.models import Func, IntegerField, Value from django.db.models.functions import Cast class SplitPart(Func): function = 'SUBSTR' template = "%(function)s(%(expressions)s)" def get_queryset(self): qs = super().get_queryset() qs = qs.annotate( major=Cast(SplitPart('version', 1, Func('version', Value('.'), function='INSTR') - 1), IntegerField()), minor=Cast( SplitPart( 'version', Func('version', Value('.'), function='INSTR') + 1, Func(SplitPart('version', Func('version', Value('.'), function='INSTR') + 1), Value('.'), function='INSTR') - 1, ), IntegerField(), ), patch=Cast( SplitPart( 'version', Func(SplitPart('version', Func('version', Value('.'), function='INSTR') + 1), Value('.'), function='INSTR') + Func('version', Value('.'), function='INSTR') + 1, ), IntegerField(), ), ).order_by('major', 'minor', 'patch') return qs Yes, it's very ugly, but should work in SQLite and Postgres (SQLite has no STRING_TO_ARRAY function), but it doesn't. Does anybody have an idea? May be there's a library providing this functionality? Thanks. -
Django + React: Can't get access to an endpoint
I have an endpoint that I made using djangorestframework. The view has a dispatch method for retrieving data from the request and sending it to post method. Endpoint: class Profile(APIView): permission_classes = [IsAuthenticated] data = None def dispatch(self, request, *args, **kwargs): if request.content_type == 'application/json': try: self.data = json.loads(request.body) except json.JSONDecodeError: return super().dispatch(request, *args, **kwargs) else: return super().dispatch(request, *args, **kwargs) I tested this endpoint with 'Authorization': 'Bearer ${token}' header using postman and rest file, and I am getting the data back with status 200. But when I do the same thing in React using axios.post method, the same user is unauthorized. Axios.post: useEffect(() => { axios.post('http://127.0.0.1:8000/user/profile/', { headers: { "Content-Type": "application/json", "Authorization": `Bearer ${token}` }, body: { "username": "Caution1", "password": "Caution123" } }).then(response => {setData(response.data); console.log(data);}); }, []); I have CORS_ALLOW_ALL_ORIGINS and CORS_ALLOW_CREDENTIALS both to True. -
Django can't display html box of authentifiation

What is meant with validation for django imagefield?
The ImageField docu states: Inherits all attributes and methods from FileField, but also validates that the uploaded object is a valid image. Yet any string is accepted class Foo(Model): pic = models.ImageField(upload_to='files') e.g. I can save this without error and nothing is uploaded to files (not even with a correct file) fooinstance.pic="bogus" fooinstance.save() fooinstance.pic.__dict__ {'_file': None, 'name': 'bogus', 'instance': <Foo:...>, 'field': <django.db.models.fields.files.ImageField: pic>, 'storage': <django.core.files.storage.filesystem.FileSystemStorage at 0x721add4903d0>, '_committed': True} Meanwhile the FileField works/uploads perfectly fine -
Securly passing authorization token from template to static javascript in Django
I am adding a custom admin page to the Django admin site where the logged in user can open a text file, it is then parsed, and the parsed data is added as a new record in a table using the user's assigned token. Is the below method secure? Is there a better strategy? I've added a custom template: {% extends "admin/change_form.html" %} {% load static %} {% block extrahead %} {{ block.super }} <script type="application/javascript" src="{% static 'js/add_cal_file.js' %}"></script> {% endblock extrahead %} {% block content %} <h1>Add cal file</h1> <div class="mb-3"> <input class="form-control" type="file" id="formFile" accept=".cal" token="{{ request.user.auth_token }}"> </div> {% endblock %} When the user selects a file the following parser in static 'js/add_cal_file.js is called: const parseCal = async (fileContents, token) => { // parses fileContents to postRequest here const response = await fetch("/api/add-calibration", { method: 'POST', headers: {"Content-Type": "application/json", "Authorization": "Token "+token }, body: JSON.stringify(postRequest) }) } The view at /api/add-calibration is protected using @permission_classes([IsAuthenticated]) limiting it to only requests that provide an authorization token
