I would like to mention, that i am NOT using the svn version, why this may
allready have been corrected. If so feel fre to delete my post.
When converting text through the gettext system, a lazystring object is
returned. This object imitates a string for all of its normal functions,
but does however lack the implementation of comparing operators (__eq__).
For this reason translated text cannot be used by validators. If attempted
the validator will try to compare a Unicode string (incomming data) with a
lazystring (translated data), which doesnt work since the __eq__ function
isn't present.
The use for translated text in validators is rellevant in cases, where a
check for submit buttons is required. Since the text is translated the
validator might look like the following:
@validate(validators={'action': validators.OneOf([_('copy'), _('move'),
_('cancel')])})
A fix for this is to to add the following snippet to the lazystring class
in turbogears/i18n/tg_gettext around line 104:
{{{
def __eq__(self, other):
return other==self.eval()
}}}
