Django - How to prevent Custom Field Validator from executing unless the field has changed?
I have a custom validator that checks that the size of the uploaded gallery image is not too big. This validator runs every time the model is saved no matter if the field has changed or not. This usually wouldn't be a big issue. The problem is that I have an admin panel inline, and any time I save the parent model "Profile" the validation inside of all the children "GalleryImages" gets executed. The validation of 50 images takes a long time since it needs to load all images and check for the resolution. How can I configure this validator to only run if the field value has been updated? # models.py @deconstructible class ImageValidator(object): """ Checks that image specs are valid """ def call(self, value): # Some code to check for max size, width and height if too_big: ValidationError('Image is too big') class Profile(Model): user = models.ForeignKey(User) class GalleryImage(Model): profile = models.ForeignKey(Profile) image = models.ImageField(validators=[ImageValidator]) # admin.py class GalleryImageInline(admin.TabularInline): model = GalleryImage @admin.register(Profile) class ProfileAdmin(ModelAdmin): inlines = [GalleryImage] -

Dynamically Create and Use Django Database Connections for Each School Without Server Restart
I am developing a Django application where schools can register, and each school has its own database. However, I am facing an issue: after creating a new database for a school, the Django server needs to be restarted for the new database to be recognized. I want to dynamically create database connections for each school without having to restart the Django server. I've tried various approaches, including creating dynamic connections using django.db.connections, but it doesn't seem to work as expected. Is there a solution or recommended approach to allow Django to dynamically create and use database connections for each new school without requiring a server restart?

Database config for Django and SQL Server - escaping the host
I have setup my Django app to use Microsoft SQL Server database. This is my database config. DATABASES = { 'default': { 'ENGINE': 'mssql', 'NAME': "reporting", 'HOST': '192.168.192.225\SQL2022;', 'PORT': 1433, 'USER': "sa", 'PASSWORD': "Root_1421", 'OPTIONS': { 'driver': 'ODBC Driver 17 for SQL Server', }, } } The SQL Server database is installed on my desktop machine and DESKTOP-RC52TD0\SQL2022 is the host\instance name. When print my config, I get the following. {'default': {'ENGINE': 'mssql', 'NAME': 'reporting', 'HOST': 'DESKTOP-RC52TD0\\SQL2022', 'USER': 'sa', 'PASSWORD': 'Root_1421', 'OPTIONS': {'driver': 'ODBC Driver 17 for SQL Server'}}} Notice that in HOST, the value has two slashes added to it, which is causing my app to not be able to connect to the database. I believe this is because of Python escaping feature for strings. How do can I escape so that I end up with a single slash and not double? As I am getting the following error: django.db.utils.OperationalError: ('HYT00', '[HYT00] [Microsoft][ODBC Driver 17 for SQL Server]Login timeout expired (0) (SQLDriverConnect)') I've tried the following and still same result: r'DESKTOP-RC52TD0\SQL2022' 'DESKTOP-RC52TD0\\SQL2022' r'DESKTOP-RC52TD0\SQL2022' Any ideas how I can escape in the context of a dictionary. In a string adding double slash \\ works but not when used in a … -
FirstValue and NthValue Django window function not working as expected
I have the following query grouped_data = ( Notification.objects .filter(type=2, user=18, is_removed=False) .values('question') .annotate( total_likes=Count('user'), most_recent_at=Max('created_at'), is_read=Min('is_read'), first_actor=Window(expression=FirstValue('actor_id'), order_by=F('id').desc(), partition_by=['question_id']), second_actor=Window(expression=NthValue('actor_id', 2), order_by=F('id').desc(),partition_by=['question_id']), ).order_by('-total_likes') ) Here's my Notification model: class Notification(models.Model): user = models.ForeignKey(User, on_delete=models.CASCADE, related_name='actors') actor = models.ForeignKey(User, on_delete=models.CASCADE, related_name='users') question = models.ForeignKey(Question, on_delete=models.CASCADE, blank=True, null=True) comment = models.ForeignKey(Comment, on_delete=models.CASCADE, blank=True, null=True) type = models.ForeignKey(NotifType, on_delete=models.CASCADE) is_read = models.BooleanField(default=False) is_removed = models.BooleanField(default=False) created_at = models.DateTimeField(auto_now_add=True) For some reason, second_actor is always None and the first_actor is always the very first actor id and not the latest actors. For example, if I have: id actor_id 20 10 19 21 18 3 I'd expect first_actor to be 10 and second_actor to be 21. What I get is first_actor as 3 and second_actor as None. Why is this happening? My underlying database is MySQL...when I do a raw query in MySQL I get the correct result. -

How to save each instance from a patch request in Djanog
In my Django appliations, I have four models, Exercise, Workout, Target, and TargetExerciseSet. Here are the models below along with my current Workout View and patch request function. The patch request is only done when a workout is completed. I have created a new model, Log (also shown below), to store each instance of a workout. My current problem here is that Object { error: "Object of type ImageFieldFile is not JSON serializable" } workout.component.ts:359:16. I have tried to workout with ChatGPT, and they are suggesting to create new tables for completed workouts, but this wont work because the database is only so big. So my question, each time a workout is completed, what would be the best way to save this data? I have tried just trying to save the exercise name and image in a json, but by time I try to view the data on my frontend application, the image url is expired. I know I can just save the exercise id, then do a request to get the exercises by ID, but I don't want to keep calling to the backend. (I know I can do one request with all the exercises).

how to run scrapy in a Django view and alert Django when the spider is finished?
I am trying to start a scrape spider from a Django view and have a method of knowing when the spider is finished. I can run the spider successfully by disabling signals in the crawler process. Like in the code below. Because the scrapy signals need to run in the main thread to function. But the only way I am currently aware of knowing when the spider has finished is using the spider_closed signal. Is there another way alert Django when the spider is finished or a method to make sure the spider and the signals run in the main thread? class PosmoScraperView(APIView): # Authentication classes authentication_classes = [TokenAuthentication] # Requires user authenticate to access permission_classes = [IsAuthenticated] def post(self, request, *args, **kwargs): # Get user input from json serializer = StartURLSerializer(data=request.data) if serializer.is_valid(): # Get url from json post request start_url = serializer.validated_data['url'] # Get spider settings process = CrawlerProcess(get_project_settings()) # Run the Scrapy spider process.crawl(BaseSpiderSpider, start_url=start_url) process.start(stop_after_crawl=True, install_signal_handlers=False) return Response({'status': 'request received'}, status=status.HTTP_200_OK) return Response(serializer.errors, status=status.HTTP_400_BAD_REQUEST) -
django pass datetime to TempusDominus
When I edit en entity I want to pass the datetime to the form, but the format is not respected. In my view I have: def get_initial(self): initial = { 'season': Season.objects.get(pk=self.request.session['selected_season_id']), 'start': self.object.start.strftime('%Y-%m-%d') if self.object.allday else self.object.start.strftime('%Y-%m-%d %H:%M') } if self.object.end is not None: initial = { 'end': self.object.end.strftime('%Y-%m-%d') if self.object.allday else self.object.end.strftime('%Y-%m-%d %H:%M') } return initial The form has following options: var picker = new tempusDominus.TempusDominus(document.getElementById(date_element_id), { //put your config here localization: { startOfTheWeek: 1, format: 'yyyy-MM-dd HH:mm', hourCycle: 'h24' }, restrictions: { minDate: new Date(), maxDate: undefined, disabledDates: [], enabledDates: [], daysOfWeekDisabled: [], disabledTimeIntervals: [], disabledHours: [], enabledHours: [], } }); picker.dates.formatInput = date => moment(date).format('yyyy-MM-DD HH:mm'); On an empty input field the datetime is shown correct. On an existing field, for an edit, the format is '12/31/2024, 16:00' But the datetime-string is passed correctly to the form and in the source I also see the correct format like '2024-12-31 16:00' . Why is the format changed? -
