On http://groups.google.com/group/django-
developers/browse_thread/thread/2c3b0d0b518d0c2f I reported that Unicode
values causes an exception when passed into messages.info() (and other 3
messages methods). In my report, I erroneously suggested that a Unicode
character in the URL's GET parameters would cause the exception. The
following example will reproduce the exception (includes extraneous steps
for the sake of completion):
== Example: ==
{{{
# The following assumes that settings are default, except the for SQLLite3
database setting, and file path, and the installed apps setting.
# Model
class Foo(Model):
name = models.CharField(max_length=255)
# Form
class FooForm(ModelForm):
class Meta:
model = Foo
# View
def create_foo(request):
if request.method == 'POST':
form = FooForm(request.POST)
if form.is_valid():
instance = form.save()
messages.info(request, 'Thanks, {0}.'.format(instance.name))
return redirect('foo_thanks')
else:
form = FooForm()
data = {
'form': form,
}
context = RequestContext(request, data)
template = Template("""<html>
<head>
<title>Bug Page</title>
</head>
<body>
<div>
<h1>Type ° (alt + 0176) into the name field, and hit
submit.</h1>
<form action="" method="post" enctype="application/x
-www-form-urlencoded">{% csrf_token %}
{{form.as_p}}
<p>
<button type="submit">Raise Exception</button>
</p>
</form>
</div>
</body>
</html>""")
output = template.render(context)
return HttpResponse(output)
def foo_thanks(request):
return HttpResponse('No need to render message, as exception occurs
upon creation.')
}}}
== Traceback: ==
