Could someone please clarify me why this url http://www.nacolmeia.com.br/do/Home/oferta/EnER
is not being accepted in a form generated from URLField's Django?
:)
Thanks
Are you hosting the site from the same server you are trying to validate it on? docs
Note that when you're using the single-threaded development server, validating a URL being served by the same server will hang. This should not be a problem for multithreaded servers.
It doesn't look like its failing validation at the form level
>>> from django import forms
>>> f = forms.URLField()
>>> f.clean('http://www.nacolmeia.com.br/do/Home/oferta/EnER')
u'http://www.nacolmeia.com.br/do/Home/oferta/EnER'
>>> f.clean('sadfas')
Traceback (most recent call last):
File "<console>", line 1, in <module>

If you don't need to validate that the website doesn't return a 404, in your models.py
url = models.URLField(verify_exists=False)
edit:
after some digging around in the django source code here
and some messing around with the shell, I'm still not sure why the URL with caps is causing a redirect loop.

The last 30x error message was:

here are some posts talking about the HTTPError: here
and here
seems like it has something to do with cookies, but I'm not able to offer a good explanation, I'll leave that to some one else.
A workaround that might work if you don't want to turn off validation but don't care about the capitalization of your urls is to override the clean_field method of your forms.
def clean_your_url_field(self):
return self.cleaned_data['your_url_field'].lower()
