How do I make the view to show a multi-step form that has forms and formsets
I want to use a multi-step form combined with some formsets in Django but I realize I need more experience on the subject. I also see that there is hardly much documentation about it and what little I find they take many things for granted. Can you help me understand how to create a view that serves as a multi-step and that saves the values of the forms and formsets? previously I was already using JS for the wizard, the only thing missing is that I save the values in the database. thanks :D Views.py def create_Presupuestos(request): extra_forms = 1 ParteFormSet = formset_factory(PresupuestosParteForm, extra=extra_forms, max_num=20) ManoObraFormSet = formset_factory(PresupuestosManoObraForm, extra=extra_forms, max_num=20) PagosFormSet = formset_factory(PresupuestosPagosForm, extra=extra_forms, max_num=20) presupuestosclientesform=PresupuestosClientesForm(request.POST or None) presupuestosvehiculosform=PresupuestosVehiculosForm(request.POST or None) presupuestosparteform=PresupuestosParteForm(request.POST or None) presupuestosmanoobraform=PresupuestosManoObraForm(request.POST or None) presupuestospagosform=PresupuestosPagosForm(request.POST or None) presupuestosfotosform=PresupuestosFotosForm(request.POST or None) if request.method == 'POST': formset = ParteFormSet(request.POST, request.FILES) manoObra_formset = ManoObraFormSet(request.POST, request.FILES,prefix='manoobra') pagos_formset = PagosFormSet(request.POST, request.FILES, prefix='pagos') if formset.is_valid() and manoObra_formset.is_valid() and pagos_formset.is_valid(): presupuestosclientesform.save() return redirect('presupuestos:index') else: formset = ParteFormSet() manoObra_formset = ManoObraFormSet(prefix='manoobra') pagos_formset = PagosFormSet(prefix='pagos') presupuestosfotosform = PresupuestosFotosForm(request.POST or None) return render(request,'Presupuestos/new-customer.html',{ 'presupuestosclientesform':presupuestosclientesform, 'presupuestosvehiculosform':presupuestosvehiculosform, 'presupuestosparteform':presupuestosparteform, 'presupuestosmanoobraform':presupuestosmanoobraform, 'presupuestospagosform':presupuestospagosform, 'presupuestosfotosform':presupuestosfotosform, 'formset':formset, 'manoObra_formset':manoObra_formset, 'pagos_formset':pagos_formset }) -
django-celery-results are not expiring even though CELERY_RESULT_EXPIRES is set
I have an every minute task running on celery beat and I'm using rabbimq as broker and have postgresql as database. As my task is running every minute and I'm storing task result in database, my database size is increasing continuously day by day. I was looking into expiration of stored task result.

How to check If any List values Exist in 2 or More Database Tables?
I have following type of Django Model. class ClientPackageMapping(models.Model): user_id=models.ForeignKey(settings.AUTH_USER_MODEL,on_delete=models.CASCADE, null=False) client_package=models.ForeignKey(ClientPackage,on_delete=models.CASCADE,blank=True, null=True) joined_date = models.DateField(null=True,blank=True) expiry_date = models.DateField(null=True,blank=True) class Meta: abstract=True @property def is_expired(self): if self.expiry_date< date.today(): return True return False class ClientPackageBasicStocks(ClientPackageMapping): stocks = ArrayField(models.CharField(max_length=5),null=True,blank=True) class ClientPackageSilverStocks(ClientPackageMapping): stocks = ArrayField(models.CharField(max_length=5),null=True,blank=True) class ClientPackageGoldStocks(ClientPackageMapping): stocks = ArrayField(models.CharField(max_length=5),null=True,blank=True) class ClientPackagePlatinumStocks(ClientPackageMapping): stocks = ArrayField(models.CharField(max_length=5),null=True,blank=True) Basically The idea is if certain user has stock in basic table but if same stock exists in another table i.e silver or gold there must be validation error.

python: RpiMotorLib in virtual environment with Django - stepper motor is rotating jerky
I´m trying to run a stepper motor (NEMA17) with a DRV8225 stepper motor controller inside a python/Djano app in a virtual environment. The script for running the stepper motor with the RPiMotorLib is the script in this tutorial: https://makersportal.com/blog/raspberry-pi-stepper-motor-control-with-nema-17 When I run the script from command line inside/outside the virtual environment, the motor is rotating smooth. But if I run the script in my Django app, the motor is rotating jerky. In Django, I´m firing the script with a Django signal after updating the database: from django.db.models.signals import pre_save from django.dispatch import receiver from django.utils.crypto import get_random_string from django.utils.text import slugify from steppermotors.models import Steppermotor import RPi.GPIO as GPIO from RpiMotorLib import RpiMotorLib import time @receiver(pre_save, sender=Steppermotor) def run_steppermotor(sender, instance, *args, **kwargs): direction= 22 # Direction (DIR) GPIO Pin step = 23 # Step GPIO Pin EN_pin = 24 # enable pin (LOW to enable) # Declare a instance of class pass GPIO pins numbers and the motor type mymotortest = RpiMotorLib.A4988Nema(direction, step, (21,21,21), "DRV8825") GPIO.setup(EN_pin,GPIO.OUT) # set enable pin as output GPIO.output(EN_pin,GPIO.LOW) # pull enable to low to enable motor mymotortest.motor_go(False, # True=Clockwise, False=Counter-Clockwise "Full" , # Step type (Full,Half,1/4,1/8,1/16,1/32) instance.last_steps, # number of steps .0005, # step delay … -

Is there a way to give alert in django admin page for not matching some constraints while adding data in fields?
Basically in my simple website I add some college fest details like name, date etc. from admin page, not from the website.

Django: exists() using queryset cache
Does django's QuerySet.exists() method use the queryset's cache if called twice? For example # this makes a call to db queryset.exists() # > true # does it make a call to the db or reuse some cached result? queryset.exists() # > true I know that len(queryset) won't make a call to the db if it has previously been evaluated. Is it the same with exists? -

Steam social login with Django backend and React frontend
I have created a steam login with python-social-auth library on the backend. That was working fine. Now I am trying to separate my backend from the frontend using React for the frontend and Django for the backend.
