Question

Django

Good evening, how to fill in the slug field automatically through the form? I am making a bulletin board, it is necessary that when a person fills out all the fields of the ad, the slug field is filled in automatically from the title, there is a model

class Advert(models.Model):
    region = models.CharField(max_length=32)
    city = models.CharField(max_length=30)
    category = models.TextField()
    title = models.CharField(max_length=32)
    description = models.CharField(max_length=900)
    photo = models.ImageField(upload_to='')
    phone_number = models.CharField(max_length=11)
    date = models.DateTimeField(auto_now_add=True, null=True)
    slug = models.SlugField(unique=True, null=True, blank=True)

    def __str__(self):
        return self.title

there is a form

class AddAdvertForm(ModelForm):
    region = forms.ModelChoiceField(queryset=Russian_Federation_Regions.objects.order_by('region'))
    city = forms.Field(widget=forms.Select)
    category = forms.ModelChoiceField(queryset=CategoryAdvert.objects.order_by('name'))
    title = forms.CharField()
    description = forms.CharField(widget=forms.Textarea)
    phone_number = forms.CharField(widget=forms.NumberInput)

    class Meta:
        model = Advert
        fields = '__all__'

class CreateAdvertView(View):
    template_name = 'bulletinboard/add_advert.html'

        return render(request, self.template_name, {'form': form})

    def post(self, request):
        form = self.form_class(request.POST, request.FILES)
