Django redirect with kwargs not working

Question

I have seen similar questions, this is not a duplicate. I have a simple redirect that recieves kwargs that is not working and I don't know why. The docs give this example:

def my_view(request):
    ...
    return redirect('some-view-name', foo='bar')

And it is exactly what I'm doing:

...
...
return redirect('perfiles:despues_contacto', razon_contacto='donacion', correo_contacto='thrall@gmail.com')

The url pattern looks like this:

url(r'^gracias_por_contactarnos/(?P<razon_contacto>[-\w]+)/(?P<correo_contacto>[-\w]+)/$',
        views.DespuesContacto.as_view(), name="despues_contacto"),

?¿ What am I missing? maybe it is something obvious ... but my eyes are tired of trying to find the error. Is it the regex?

@Selcuk `Reverse for 'despues_contacto' with arguments '()' and keyword arguments '{'razon_contacto': u'donacion', 'correo_contacto': u'thrall@gmail.com'}' not found. 1 pattern(s) tried: [u'perfil/gracias_por_contactarnos/(?P[-\\w]+)/(?P[-\\w]+)/$']` ... looks like its the regex. — Alejandro Veintimilla, Apr 06 '16 at 00:12
It looks like your correo_contacto regex does not accept @ and dot (.) signs. — Selcuk, Apr 06 '16 at 00:14
@Selcuk Yup... I'm trying to find a regex that does ... do you have one? — Alejandro Veintimilla, Apr 06 '16 at 00:15
Just Google for a regex that matches email addresses. There are many possible combinations you should take into account. — Selcuk, Apr 06 '16 at 00:19
Looks like its really complex: http://stackoverflow.com/questions/201323/using-a-regular-expression-to-validate-an-email-address — Alejandro Veintimilla, Apr 06 '16 at 00:21

Ok so the regex was wrong, it didn't accept "@" or "." ... and because it is really difficult to use a regex for emails, as described in this SO question. I processed the email, then send it to the url, and manually built it again:

email_for_url = email.split(".")[0].replace("@", "-")    
return redirect('perfiles:despues_contacto', razon_contacto=razon_contacto, correo_contacto=email_for_url)

...
def get_context_data(self, **kwargs):
   ....
    email = kwargs["email"].replace("-", "@") + ".com"

What if original email already has `"-"` before `"@"`? It will rebuild wrong email. If you have to do it like this, use more complex identifier for `"@"` i.e. `"--__--"`. – primoz Apr 06 '16 at 07:04

.Very simple. You only change regular expression of url to it undestand parameter have @ character.

urls.py

    url(r'^gracias_por_contactarnos/(?P<razon_contacto>[-\w]+)/(?P<correo_contacto>[\w\-@.]+)/$',
    views.DespuesContacto.as_view(), name='despues_contacto'),

Thanks for the answer man. I'll accept this answer. But the regex is incomplete, it needs to accept dots too. Please update it and I'll accept. – Alejandro Veintimilla Apr 07 '16 at 02:25
You have to add dots after @ in regex – Son Lam Apr 07 '16 at 02:36
