Overriding Save in Model

[cale...@gmail.com]

I'm trying to extract an entered domain name and split it up so that i can store unique domains in a specific table

The flow

user will enter website address > model takes website address > splits it into sub_domain, domain and suffix and stores the values in the appropriate split fields

so far my extraction works, i can get the values into a list and assign the values to the appropriate variables, using the shell i'm adding new sites but and the domain is going into the domain_name field but i am not getting the data split

I'm only two weeks into learning python and Django and i love it but this has stopped me in my tracks for now, any help appreciated

class Website(models.Model):
    name = models.CharField(max_length=100, default=' ')
    description = models.TextField(max_length=2000, blank=True)
    domain_name = models.URLField(unique=True)
    sub_domain =models.CharField(max_length=56, blank=True, default='')
    suffix = models.CharField(max_length=56, blank=True, default='')
    is_secure = models.BooleanField(null=True)
    logo = models.CharField(max_length=256, default="placeholder.png")
    type = models.CharField(choices=WEBSITE_TYPES, default='O', max_length=15)

    def __str__(self):
        return self.name


    def validate_and_split_domain(self):
        domain = self.domain_name.lower() # make all lower case because django isn't case sensitive
        values = list(tldextract.extract(domain))
        self.sub_domain, self.domain_name, self.suffix = values[0], values[1], values[2]

    def save(self, *args, **kwargs):
        Website.validate_and_split_domain()
        super(Website, self).save(*args, **kwargs)

thanks,  i've got tldextract which is sufficient for splitting the domain up

the problem is I cannot save the individual parts and only end up saving the domain name

You’re converting an object (ExtractResult) into a list.  That’s just weird.

 

        ext = tldextract.extract(domain)

        self.sub_domain = ext.subdomain

        self.domain = ext.domain

        self.suffix = ext.suffix

 

Saying that, I would rather use the built-in, Pythonic way of parsing URLs.

Thanks, I did say i was only two weeks into learning python and Django.

I'm sure in a few months, maybe weeks or even days, i'll look back at my code and say wtf
