Hi,
I have problems with setting ``errors`` in ``htmlfill.render()`` as
dictionary with values as ``Invalid`` exception instances with
unicode ``msg``. I get ``UnicodeEncodeError`` from
``html_quote()``. Problem exist in version 1.0.1 and in current code from svn.
When looked in code from svn I found that some attempt was made to
handle unicode in ``html_quote()`` by using ``__unicode__()`` method
if object passed to it provide one. Unfortunately ``class`` Invalid
haven't.
Adding this to ``Invalid`` class definition work for me::
def __unicode__(self):
val = self.msg
if isinstance(val, unicode):
return val
else:
return unicode(val)
Probably ``__str__()`` method should be change also to always return
``str`` type object because now if ``msg`` is unicode--unicode will be
returned and that is not what is probably expected.
One thing need additional consideration--in solution shown above only
default encoding (ascii) is used. Some users may need to customize
this. Additional key parameter ``encoding`` that could be passed to
``Invalid.__init__()`` could handle this. It then should be used in
``__str__()`` and ``__unicode__()``. E.g. like this::
def __unicode__(self):
val = self.msg
if isinstance(val, unicode):
return val
elif encoding:
return unicode(val, encoding)
else:
return unicode(val)
