I need to return a link generated after the completion of ModelForm

Question

part of forms.py

class FormPublicar(forms.ModelForm):

class Meta:
    model = Publicacao
    exclude = ('usuario', 'aprovado', 'cadastrado_em', 'slug')

def enviar(self):
    titulo = 'mensagem enviada pelo site'
    destino = self.cleaned_data['emailp']
    mensagem = u"""
    Message that will be sent after completing the form.
    Here I must pass a link to the full URL into the body of the email, something like:
    [ 1 ]http://www.domain.com/item/playstation3/
                         /view/slug/   
    """  % self.cleaned_data

    send_mail(
        subject = titulo,
        message = mensagem,
        from_email = '[email protected]',
        recipient_list =[destino],
        )

[ 1 ] I read about the "reverse", tried to mount url + view + parameter. But I could not generate the link correctly, did a number of ways but could not.

I need to pass the domain name+view+parameter slug that is generated after completing the form.

For the recipient of e-mail see the correct link.

Can anyone help me? Thanks in advance.

Answer 1

Using reverse() is normally the proper way to generate the portion of the URL without the domain. For example, if your URL config contains something like the following:

(r'^item/(?P<item>[-%\w]+)/view/(?P<slug>[-\w]+)$', 'my_view_function')

Then the following call

reverse('my_view_function', kwargs={'item': 'playstation3', 'slug': 'my-slug'})

should return /item/playstation3/view/my-slug.

Preferably, your model Publicacao should define a get_absolute_url method that returns the actual URL for the model instance. See http://docs.djangoproject.com/en/1.2/ref/models/instances/#get-absolute-url.

The domain name part could be retrieved using the Sites framework:

>>> from django.contrib.sites.models import Site
>>> s = Site.objects.get_current()
>>> s.domain
u'localhost:8000'

Of course, you will have to configure the domain of your site properly. See also http://docs.djangoproject.com/en/1.2/ref/contrib/sites/#getting-the-current-domain-for-full-urls.

Bernd, thanks. About the "reverse" I already knew.

A short example. here is only a matter of identation. http://pastebin.ca/1977489

Thanks and I apologize, I'm still studying Django.
