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? -

(Apologies if I explain this badly, I will explain it as well as I currently know how.) I have set up a volume within my docker-compose-prod.yml with the aim of serving static content here via those volumes and nginx. As part of that I have added the creating of the volumes to Dockerfile and edited the urls.py and settings.py to look for the relevant url patterns and set the STATIC_ROOT.

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. How can I fix this? -

Django: include a url with no namespace
I have an a Django app, with respect to the project root at applib/hw/apps.py The name attribute of the config class within this apps.py is applib.hw. The app controls how a user is logged in.

annotate missing grouping keys with zero
I have models: class Deviation(models.Model): class DeviationType(models.TextChoices): TYPE1 = 'type1', TYPE2 = 'type2' COMMON = 'common' type = models.CharField( _('deviation type'), choices=DeviationType.choices, max_length=25, default=DeviationType.COMMON, ) class Task(models.Model): name = models.CharField() deviation = models.ForeignKey(Deviation) ORM request: res = Task.objects.values('deviation__type')\ .annotate(type=F('deviation__type'), count=Count('pk'))\ .values('type', 'count') As you can see the aim is to count Tasks grouping by deviation__type. If there is no Tasks with specific deviation__type, they will not be in res. For example if there no Tasks with deviation__type=COMMON the res will be: [ { "type": "type1", "count": 9 }, { "type": "type2", "count": 10 } ] Is that possible to add missing records in res like that: [ { "type": "losses", "count": 9 }, { "type": "personnel", "count": 10 }, { "type": "common", "count": 0 } ] ?
