On admin django choose one element in a list and have same result in the inline
If we consider that "client" is a dropdown list, would it be possible to reflect the choice made in StatusAdmin in my StatusTextInline class in order to have only one client associated please?

Access Multiple PDF Files with Django Rest Framework and REACT frontend

Add Field Update
With the help of a button, I developed a code that allows the area I want to be added as the button is pressed, and this code works without any problems. When I reopen the form to update it, the data comes in as I added and I save it again, then when I enter the updated form, the data is lost. So I'm giving an example, I pressed the button 3 times and 3 fields came to enter, I filled in 3 of them and saved, then when I enter to update, it appears in 3 data. When I exit the update screen and enter that form again, only the most recently added data appears from the 3 data. models.py class Records(models.Model): username = models.CharField(max_length=1000, verbose_name='Ad Soyad',null=True,blank=True) date = models.CharField(max_length=1000,null=True,blank=True) hours = models.CharField(max_length=1000,blank=True,null=True) tel = models.CharField(max_length=1000,verbose_name='Telefon Numarası',null=True,blank=True) tcNo = models.CharField(max_length=1000, verbose_name='TC Numarası',null=True,blank=True) adress = models.CharField(max_length = 1000,verbose_name='Adres/Köy',null=True,blank=True) kurum = models.CharField(max_length=1000,verbose_name='Kurum',null=True,blank=True) diagnosis = models.CharField(max_length=1000, verbose_name='Tanı',null=True,blank=True) intervention = models.CharField(max_length=1000, verbose_name='Müdahale', null=True,blank=True) # medications = models.CharField(max_length=1000, verbose_name='İlaçlar', null=True,blank=True) conclusion = models.CharField(max_length = 1000,verbose_name='Sonuç',null=True,blank=True) doctor = models.CharField(max_length=1000, verbose_name='Doktor',null=True,blank=True) record_one_measurement = models.CharField(max_length=1000, verbose_name='1.Ölçüm',null=True,blank=True) record_one_blood_pressure = models.CharField(max_length=1000, verbose_name='1.Tansiyon',null=True,blank=True) record_one_pulse = models.CharField(max_length=1000, verbose_name='1.Nabız',null=True,blank=True) record_one_spo2 = models.CharField(max_length=1000, verbose_name='1.SPO2',null=True,blank=True) record_one_respirations_min = models.CharField(max_length=1000, verbose_name='1.Solunum/DK',null=True,blank=True) record_one_fire = models.CharField(max_length=1000, verbose_name='1.Ateş',null=True,blank=True) record_second_measurement … -

Automatically Move data to archive table if date is older
I have a gallery model in my models.py. I want to automatically move the data to another table called as Archive if created date is more than 30 days. This is my models.py class Gallery(models.Model): id= models.AutoField(primary_key=True) name = models.CharField(max_length=100) image = models.ImageField(upload_to='images/') video = models.FileField(upload_to='videos/', validators=[FileExtensionValidator( ['mp4', 'mov', 'mkv'] )]) tag = models.CharField(max_length=100) classes = models.ForeignKey(Classes, null=True, blank=True, on_delete=models.CASCADE) level = models.ForeignKey(Level, null=True, blank=True, on_delete=models.CASCADE) uploded_date = models.DateTimeField(auto_now_add=True) class Archive(models.Model): id= models.AutoField(primary_key=True) name = models.CharField(max_length=100) image = models.ImageField(upload_to='images/') video = models.FileField(upload_to='videos/', validators=[FileExtensionValidator( ['mp4', 'mov', 'mkv'] )]) tag = models.CharField(max_length=100) classes = models.ForeignKey(Classes, null=True, blank=True, on_delete=models.CASCADE) level = models.ForeignKey(Level, null=True, blank=True, on_delete=models.CASCADE) uploded_date = models.DateTimeField(auto_now_add=True) I have thought of creating signals and sending signals to Archive like this. I have already defined the signal. def date_is_old(self): if self.uploded_date > (datetime.datetime.now()-timedelta(days=15)): date_is_old.send(self.__class__) But this method seems to be ineffective as it only sends signal at time of creation of new record. I need the function to always check and If creation is past 30 days automatically move data to Archive. Is there some way to handle this? I am really out of option tried modifying create method and save methods on table "Gallery". -

How to access a specific user's model data as admin?
I'm creating a simple model form that is only available to staff. It has a user selection dropdown list populated by models.py user = models.ForeignKey(User, on_delete=models.CASCADE). On submit I need my view to look up the selected user from the form and return the data in the models for that user (from the built-in Django database). How would I go about doing this? I have searched here and the recommended articles, but they all appear to be for accessing a model as the logged-in user. Here is a screenshot of the form and my code: models.py class GetData(models.Model): user = models.ForeignKey(User, on_delete=models.CASCADE) forms.py class DataRequestForm(forms.ModelForm): class Meta: model = GetData fields = ['user'] Views.py @login_required def data_form(request): if request.user.is_staff == True: if request.method == 'POST': form = DataRequestForm(request.POST) if form.is_valid(): user = request.POST["user"] print("Form is Valid") print(user) # How to access that user's model data here? -

Django - set timezone in a django-admin command
I have a django-admin command which is handling message sending to different users in different countries. Each user should get the message at the same date - according to their local timezone. For example: a user in Paris should get a message every Monday at 10 am (Paris time), and a user in NY should get a message every Monday at 10 am (NY time). What happens is that they both get the message at Monday 10 am GMT. I can't use the user's browser local timezone, because its a script running independently in my server. Instead, I want to send the message according to a TZ stored in my DB for each users preferences. How can I send the message according to each user's TZ in my "handle" function? I was trying to use the "django.utils.timezone.activate" but I am not really sure how to make it work -
