How to override save () method of modelform class and add missing information?

Question

I was just starting to learn Django, and I had a question.

I am trying to automatically add missing information when saving form data. I get to change / add the necessary information "cleaned_data" by overriding the save () method of the modelform class, but the changes are not written to the database. Actually, how to write the changed information? This is the code:

def save(self, commit = True, *args, **kwargs):
    temp = ServiceMethods(url = self.cleaned_data.get('url'), wsdl_url = self.cleaned_data.get('wsdl_url'))

    if not temp.get_wsdl_url():                             
        temp.make_wsdl_url()

    if temp.get_wsdl_url():                                 
        temp.make_wsdl()                                    
        self.cleaned_data['wsdl_url'] = temp.get_wsdl_url() 
        self.cleaned_data['wsdl_description'] = temp.get_wsdl_description()

    super(ServiceForm, self).save(commit = commit, *args, **kwargs)  

And the model:

class Services(models.Model):
    name                = models.CharField('', max_length=256)
    url                 = models.URLField('', unique = True)
    wsdl_url            = models.URLField('  WSDL-', blank=True)
    description         = models.TextField(' ',blank=True)
    wsdl_description    = models.TextField('WSDL ', blank=True, editable=False)
    added               = models.DateTimeField('', auto_now_add=True)

TIA

Try setting the data on self.instanceinstead self.cleaned_data, and let me know if this works.
