I am having an issue with rendering Django's ErrorList if one of my error
list items is unicode. When Django renders my errorlist
{{{
{{ form.non_field_errors }}
}}}
it runs the following code:
{{{
class ErrorList(list, StrAndUnicode):
"""
A collection of errors that knows how to display itself in various
formats.
"""
def __unicode__(self):
return self.as_ul()
def as_ul(self):
if not self: return u''
return mark_safe(u'<ul class="errorlist">%s</ul>'
% ''.join([u'<li>%s</li>' %
conditional_escape(force_unicode(e)) for e in self]))
}}}
then in force_unicode:
{{{
s = unicode(str(s), encoding, errors)
}}}
and then translation in lazy:
{{{
def __str_cast(self):
return str(self.__func(*self.__args, **self.__kw))
}}}
The problem is that my string contains 'å' symbol and str(u'å') raises
UnicodeEncodeError. Is there a good reason why force_unicode and lazy do
not use smart_str? I have to do it myself and provide error messages as
str objects instead of unicode to make it work.
So I get TemplateSyntaxError Caught UnicodeEncodeError while rendering:
'ascii' codec can't encode character u'\xe5' in position 17: ordinal not
in range(128). This seems telling that rendering my error list item (which
is u'å') caused the first UnicodeEncodeError having unicode message
'ascii' codec can't encode character u'\xe5' and then second
UnicodeEncodeError while rendering the message from the first one. Am I
mistaken?
Django version: 1.3.1 (but this seems to happen in 1.4 as well)
