Description

Hello,

Just reporting that the validation for URLFields fails incorrectly with URLs similar to the below.

​http://foo.com/1-2.html#bar

Original case:
​http://www.ens-newswire.com/ens/jun2007/2007-06-05-09.asp#anchor2

is incorrectly rejected.

Cannot reproduce with v9690. The URLField regex seems OK to me.

In [10]: from django import forms

In [11]: f = forms.URLField()

In [12]: f.clean('http://www.ens-newswire.com/ens/jun2007/2007-06-05-09.asp#abc')
Out[12]: u'http://www.ens-newswire.com/ens/jun2007/2007-06-05-09.asp#abc'

I definitely have a plain-vanilla URLField that fails on that url and the cases noted above in real usage (oggy's code works fine for me). Will dig into this and see what's happening.

Nope, this is definitely an issue. I haven't been able to track down what's causing it, but I get it in a brand-new app, for an otherwise well-behaved URLField.

To reproduce, try entering one of the above URLs into any admin interface URLField, or use an app like the below:

urls.py:

from django.conf.urls.defaults import *
from test_app.models import *
urlpatterns = patterns('django.views.generic.create_update',
    (r'^', 'create_object',{'model':TestModel}),
)

settings.py:

ROOT_URLCONF = 'urls'

import os
PROJECT_PATH = os.path.abspath(os.path.dirname(__file__))
TEMPLATE_DIRS = (
    os.path.join(PROJECT_PATH, 'templates')
)

INSTALLED_APPS = (
	'test_app',
)

test_app/models.py:

from django.db import models

# Create your models here.
class TestModel(models.Model):
	test_url = models.URLField()

templates/test_app/testmodel_form.html

<html><head></head>
<body>
	<form action="." method="POST">
	{{form}}
	<input type="submit"/>
	</form>
</body>

On runserver, and load of 127.0.0.1:8000, enter one of the URLs in the original ticket, and receive "This URL appears to be a broken link."

You get that error because verify_exists is True on models.URLField (see ​http://docs.djangoproject.com/en/dev/ref/models/fields/#urlfield). In other words it will make sure that the above URLs won't return a 404. If you don't need this functionality just set verify_exists to False (and it gives a that error on the second URL because that particular server will return a 400 error code for that).

Note: See TracTickets for help on using tickets.
