#14941 closed (fixed)

URLField (in django.contrib.admin) rejects IDN domain

Description

I tried to add a new entry using the admin interface.
But when the URLField contains any unicode char (for IDN domains), like http://de.wikipedia.org/wiki/Tür, I am getting the following error:

Enter a valid URL.

According to the documentation, this bug was fixed in 1.2 and it does work in the shell:

>>> from django.core.validators import URLValidator
>>> v = URLValidator()
>>> v('http://de.wikipedia.org/wiki/Tür')
>>>

I can reproduce this error even in a standard form. This is not related to the admin.

After some research, this is related to the URL verification. Try:

>>> from django.core.validators import URLValidator
>>> v = URLValidator(verify_exists=True)
>>> v('http://de.wikipedia.org/wiki/Tür')

     86             except ValueError:

     88             except: # urllib2.URLError, httplib.InvalidURL, etc.
     89                 raise ValidationError(_(u'This URL appears to be a broken link.'), code='invalid_link')

ValidationError: [u'Enter a valid URL.']

I'm attaching a patch that encodes url before passing it to urllib2. Testing is tricky, as it implies network access.

Note also that this is not solving IDN domain validation problem (#12988).

I saw there was already tests calling the network, so I added this one
