[F] views: fix 2 unicode errors 1. You can now use valid unicode strings in ValidationError exception. Previously, if 'err' contains unicode, UnicodeDecodeError was raised by format_errors() >>> templstr = '<li>%s</li>\n' >>> e = ValidationError(None, {None: u'oué, une exception en unicode!'}) >>> templstr % e '<li>None (None): ou\xc3\xa9, une exception en unicode!</li>\n' >>> templstr = u'<li>%s</li>\n' >>> templstr % e u'<li>None (None): ou\xe9, une exception en unicode!</li>\n' 2. The message of an Exception can contains unicode. But it now properly managed by “informal” string representation. We can easily fix the problem by using the Exception.message attribute that still contains the original message. >>> a = AssertionError(u'séfdsdf') >>> a.message u's\xe9fdsdf' >>> str(a) Traceback (most recent call last): File "<stdin>", line 1, in <module> UnicodeEncodeError: 'ascii' codec can't encode character u'\xe9' in position 1: ordinal not in range(128) >>> a = ValueError(u'fsdfsdéfsdfs') >>> str(a) Traceback (most recent call last): File "<stdin>", line 1, in <module> UnicodeEncodeError: 'ascii' codec can't encode character u'\xe9' in position 6: ordinal not in range(128) >>> a ValueError(u'fsdfsd\xe9fsdfs',) >>> unicode(a) Traceback (most recent call last): File "<stdin>", line 1, in <module> UnicodeEncodeError: 'ascii' codec can't encode character u'\xe9' in position 6: ordinal not in range(128) >>> a.message u'fsdfsd\xe9fsdfs'
