Django Model

[Максим С]

Hello all.

I'm beginer. Sorry. Can anyone help me with this model. It did't work(TypeError: expected string or bytes-like object

):

import whois

class Domains(models.Model):
    domainname = models.CharField(max_length=200, blank=True)
    domainuser = models.ForeignKey(User, on_delete=models.CASCADE)
    details = whois.whois(domainname)
    w = str(details.expiration_date)
    domainwhois = models.DateField(default=w)

    def __str__(self):
        return self.domainname

Domains.save()

Hi,

If I got this right, what you want to do is save the "domainwhois" with the expiration date of the result of the whois.whois function.

Unfortunately, things don't work in class level like this, because things are static here: whois.whois will be run one single time, not on every object. For that, you'll need to change something in the instance. Fortunately, Django allows access to things in the instance with ``save``:

def save(self, *args, **kwargs):

   details = whois.whois(self.domainname)

   self.domainwhois = details.expiration_date

   super().save(*args, **kwargs)

("details" and "w" can be removed from the model itself, as they are variables used only for retriving this information). Have a look how models work here: https://docs.djangoproject.com/en/2.0/topics/db/models/

import whois

class Domains(models.Model):
    domainname = models.CharField(max_length=200, blank=True)
    domainuser = models.ForeignKey(User, on_delete=models.CASCADE)
    details = whois.whois(domainname)
    w = str(details.expiration_date)
    domainwhois = models.DateField(default=w)

    def __str__(self):
        return self.domainname

Domains.save()

domaine=Domaine()

domaine.domainename=.....

domaine.domaineuser=User.objects.last()

domaine.details=.......

domaine.save()
