Django only able to handle 3 actions at same time?
Hello apologies as I am incredibly new to Django. I have a Django site deployed to an AWS ec2 with Gunicorn and Nginx. Essentially within the app the user clients a button some python code kicks off and ~10 seconds later the work is done. This works perfectly until there are more than 3 actions going on at the same time. If I were to open 3 tabs and click 3 buttons at roughly the same time, the entire site can't do anything else. No other pages will load or anything. The aws EC2 has 2 codes. Gunicorn is set to 5 workers. I tried increasing the size of the ec2 to an instance with more cores thinking that might be it but unfortunately no dice. Would anyone have a clue what might be going on? -
Django Direct assignment to the reverse side of a many-to-many set is prohibited. Use .set()
I have two models, StudyConditions and studies, and there exists a many to many relationship between the two, declared in studies. I am trying to create new conditions in my StudyConditionViewSet and link them to the studies. When doing a post request with the JSON object below, I get the error Direct assignment to the reverse side of a many-to-many set is prohibited. Use .set(). Is this just not possible, i.e I can only do this in my StudyViewSet, or is there something I'm missing/misunderstanding? There aren't many issues I've seen concerning this specific case. I've tried both study_obj.conditions.add(new_condition) and new_condition.studies.add(study_obj), trying to add the condition to the study in the first, and trying to add the study to the condition in the second. I've also tried them using set, but with no success. { "name": "Post w/ studies", "studies": [ { "id": "1" }, { "id": "2" } ] } models.py class Study(models.Model): featured = models.BooleanField(default=False) conditions = models.ManyToManyField('StudyCondition', related_name='studies', db_table='Study_Condition') class Meta: db_table = 'Study' class StudyCondition(models.Model): name = models.TextField(null=False) class Meta: db_table = 'Condition' views.py class StudyConditionViewSet(viewsets.ViewSet): def list(self, request): queryset = StudyCondition.objects.all() result = StudyConditionSerializer(queryset, many=True) if result: return Response(result.data) else: return Response(data=result.data, status=200) def retrieve(self, … -

how to Extract days from DateField in django
interval = Attribute.objects.filter(Q(register_date__gte='2021-07-01')) \ .annotate(input_interval=Cast('create_at', DateField()) - F('register_date')).values('student_id', 'input_interval') The date you registered the student is register_date and the model property is DateField . The date/time that each student's enrollment date was entered into the actual program is create_at and the model property is DateTimeField . The two fields have different model properties, so I converted the create_at field to a DateField using the Cast function. And (actual input date) - (student enrollment date) was obtained. The result is as below. <QuerySet [{'student_id': 1, 'input_interval': datetime.timedelta(days=1)}, {'student_id': 2, 'input_interval': datetime.timedelta(0)}, {'student_id': 3, 'input_interval': datetime.timedelta(0)}, {'student_id': 4, 'input_interval': datetime.timedelta(0)}]> Is there a way to extract only the days value of input_interval from here? I googled and tried functions such as ExtractDay, days, etc., but the date returned using the Cast function is Is it impossible to extract... Please help. -
Django: If an object from a database is deleted do the remainer objects keep the same id/order?
This might be a stupid question but here I go: I have a SQLite database with Django. Let's say in one table i have four objects: ID=1 name=dog ID=2 name=cat ID=3 name=lion ID=4 name=rat If I were to delete an object let's say animals.objects.get(id=3).delete() Do the id's from the other objects change? Would it be: ID=1 name=dog ID=2 name=cat ID=3 name=rat They change right? I am supposing they do. And if they do is this so in other databases like MySQL? -
Logging activity django backend react
I have a react application that uses django rest framework as a backend. Problem is the server the react application is hosted on is a flask application (long story..not my monster). I would like to keep a log of activity from the react app, but I would also like to add some custom data from the react front end when these logs are generated that goes to the back end. Any help would be appreciated. -

Django Model Calculation Performing however .save() not updating postgresql database
I have some code that is basically supposed to execute on a button click. if response.POST.get("calculate"): sh.isEdit=False temp=[] for link in sh.tablink_set.all(): temp.append([link.link, link.tournName]) print(link.link) sh.createdsheet=finalCalc(temp) sh.save(update_fields=['isEdit', 'createdsheet']) everything is working fine, except for the last line to save. I know the rest of it is working, as a) the calculation performs fine as I printed the result to the console, and that looked totally fine. Moreover, I know that the saving issue is associated with the 'createdsheet' and not the boolean 'isEdit', as prior to adding 'createdsheet', my script was working fine. In my model, createdsheet is an 3-d arrayfield, and similarly, the function I call, 'finalCalc' returns a 3-d array. class eloSheet(models.Model): user=models.ForeignKey(User, on_delete=models.CASCADE, related_name="elosheet", null=True) name= models.CharField(max_length=500) startYear=models.CharField(max_length=4) endYear=models.CharField(max_length=4) createdSheet=ArrayField( ArrayField( models.CharField(max_length=100) ) ) isEdit=models.BooleanField(default=True) The error I get from the terminal is raise ValueError("The following fields do not exist in this " ValueError: The following fields do not exist in this model or are m2m fields: createdsheet however I know that the field does exist (I went to the admin page to confirm it was in the model) however I am unclear on what a ManyToMany field is.

Django Update fileinput widget doesnt work when field is required
I have a FileField in the form that I'm passing to my updateview. The default widget clearablefileinput is visually disgusting, so I changed it to the simple fileinput. The issue is that when I set my field to required in init method, the update doesnt work. Nothing happens when I push the update button. I only have 2 ways to make it work it seems: widget = fileinput but required = false widget = clearablefileinput and required = true I have no idea how these things work behind the scenes and honestly I'm angry that django is making me tackle the stupid clearable file input. Is there any way to make the fileinput work even when required = true? -

Using Weasyprint to create file response
I am making a web application with Django relating to guitar chord sheets. One of the features is the ability to generate a PDF from a chord sheet and download it. I am using Weasyprint to generate the PDF, but I'm getting a problem where instead of downloading the file, the view just shows a really long sequence of digits. Here's my view function: def download_pdf(request, song_id): song = get_object_or_404(Song, pk=song_id) song.chordsheet.open("r") chordsheet_html = HTML(string=chopro2html(song.chordsheet.read())) # Generates HTML from a text file, not relevant here chordsheet_css = CSS(string="div.chords-lyrics-line {\n" " display: flex;\n" " font-family: Roboto Mono, monospace;\n" "}\n") song.chordsheet.close() return FileResponse(chordsheet_html.write_pdf(stylesheets=[chordsheet_css]), as_attachment=True, filename=song.title + "_" + song.artist + ".pdf") And when I run the code, I get this: <html> <head></head> <body> (a 53,635-digit number here) </body> </html> For what it's worth, I have a similar view function that does the same thing except without the PDF generation (downloads the raw file) and it works fine.
