Question

In one of my Django models, I override the save function. I do this to get the user’s username. But that keeps failing.

this is what i did:

    def save(self, *args, **kwargs):
    self.slug = slugify('%s' % (self.question))
    if not self.id:
        self.publish_date = datetime.datetime.now()
        self.publisher = self.request.user
    self.modification_date = datetime.datetime.now()
    self.modifier = self.request.user
    super(Faq, self).save(*args, **kwargs) # Call the "real" save() method

This fails with:
‘Faq’ object has no attribute ‘request’

Thanks.

If this is for use within the Admin app, as you say in your answer to Jake, then you shouldn’t override the model save method at all. Instead, you should override the save_model method of the ModelAdmin class.

See the original code in django.contrib.admin.options – you’ll see that it’s already passed the request object. So all you need to do is to assign the publisher there:

def save_model(self, request, obj, form, change):
    obj.slug = slugify('%s' % (obj.question))
    if not obj.id:
        obj.publish_date = datetime.datetime.now()
        obj.publisher = request.user
    obj.modification_date = datetime.datetime.now()
    obj.modifier = request.user
    obj.save()
