how to access to property in view(django)
I'm beginner and I need some solution First, I have Racket and Detail class. class Racket(models.Model): name = models.CharField(max_length=20) class RacketDetail(models.Model): racket = models.OneToOneField(Racket, related_name='detail', on_delete=models.CASCADE) adminReview = models.TextField() adminPower = models.FloatField(default=0) adminSpin = models.FloatField(default=0) adminManeuverability = models.FloatField(default=0) adminStability = models.FloatField(default=0) adminComfort = models.FloatField(default=0) @property def adminAvgScore(self): scoreAvg = ( self.adminPower + self.adminSpin + self.adminManeuverability + self.adminStability + self.adminComfort ) / 5 return round(scoreAvg, 2) Second, I want to rander list using the @property(adminAvgScore), so I made view like this. def racketMain(request: HttpRequest): getRacket = Racket.objects.all().order_by('detail__adminAvgScore') return render(request, "racket/racketMain.html", {'racketItems': getRacket, }) Unfortunally when I use 'RacketDetail' class's column I can access all column except 'adminAvgScore' using by "order_by('detail__". If I use like "order_by('detail__adminAvgScore')" then Django show to me error "Unsupported lookup 'adminAvgScore' for BigAutoField or join on the field not permitted." How can I solve it? Or should I think in a different way? -
Django python + javascript countdown – time is off by 3 hours
I am relatively new and just a hobbyist programmer. At the moment I try to work on a small Django project where I want to set a date and time in the future via a form and after the user clicks "Submit", the page shows a countdown from now until the set date and time. After experimenting a bit with the datetime module, I find myself with an awkward problem. I have two fields in the forms: 1. date, and 2. time With timestamp = datetime.datetime.combine(date, time).strftime('%s') I combine those two information and get a seconds output. I then, pass timestamp to my .js file with {{ timestamp|json_script:'timestamp'}}. In javascript, I do the following: const setTime = JSON.parse(document.getElementById('timestamp').textContent); var difference = setTime * 1000 - now.getTime(); //Python gives me seconds not milliseconds date = new Date(difference); datevalues = [ date.getYear() - 70, date.getMonth(), date.getDate() - 1, date.getHours(), date.getMinutes(), date.getSeconds(), ]; document.getElementById("countdown").innerText = datevalues[0] + "years" + datevalues[1] + "months" + datevalues[2] + "days" + datevalues[3] + "hours" + datevalues[4] + "minutes" + datevalues[5] + "seconds" + setTime * 1000 + " ... " + now.getTime() + " ... " + difference let t = setTimeout(function () { timer() }, 1000); … -

How to access a specific element from a CHOICES list in Django?
In my models, I have a choices list, such as: class Graduation(models.Model): YEAR_IN_SCHOOL_CHOICES = [ ('FR', 'Freshman'), ('SO', 'Sophomore'), ('JR', 'Junior'), ('SR', 'Senior'), ('GR', 'Graduate'), ] student_level = models.CharField(max_length=2, choices=YEAR_IN_SCHOOL_CHOICES) In my views, I want to get the value for a specific element. I have this: search = 'JR' all_choices = Graduation.YEAR_IN_SCHOOL_CHOICES My goal is to get Junior returned by the system. How can I do that? I tried: all_choices[search] but that doesn't work. I know I can change the format of my choices list in the models, but in this case my models can not be changed. What is the right way to obtain the label from this list? Do I have to loop through the list and use an if statement? That doesn't seem efficient but I am not sure if I have another choice. -

What is the best way to transfer large files through Django app hosted on HEROKU

The file itself is coming from a different source ( requests python package ) The idea is to build a file transfer utility using Django app on HEROKU. The file will not gets stored in my app side. Its just getting from point A and sending to point B. Went through multiple discussions along with the standard HEROKU documentations, however I am struggling in between in some concepts: Will this problem be solved by background tasks really? ( If YES, I am finding explanation of the process than the direct way to do it such that I can optimise my flow ) As mentioned in standard docs, they recommend background tasks using RQ package for python, I am using Postgre SQL at moment. Will I need to install and manage Redis Database as well for this. Is this even related to Database? Some recommend using extra Worker other than … -

mod_wsgi-express causing ModuleNotFoundError: No module named "mod_wsgi.server"

I'm trying to run the following command to run mod_wsgi-express: mod_wsgi-express start-server django_wsgi.py --server-root /var/www --user apache --group apache --port 80 --host XYZ where XYZ is the IP of the machine i'm running this command on.
