Rewrite IS_IN_SET, everything is ok. But I don't know how to submit a
branch .
class IS_IN_SET(Validator):
def __init__(
self,
theset,
labels=None,
error_message='value not allowed',
multiple=False,
zero='',
sort=False,
):
self.multiple = multiple
if isinstance(theset, dict):
self.theset = [str(item) for item in theset.keys()]
self.labels = theset.values()
elif theset and isinstance(theset, (tuple,list)) \
and isinstance(theset[0], (tuple,list)) and
len(theset[0])==2:
self.theset = [str(item) for item,label in theset]
self.labels = [str(label) for item,label in theset]
else:
self.theset = [str(item) for item in theset]
self.labels = labels
self.error_message = error_message
self.zero = zero
self.sort = sort
def options(self):
if not self.labels:
items = [(k, k) for (i, k) in enumerate(self.theset)]
else:
items = [(k, self.labels[i]) for (i, k) in
enumerate(self.theset)]
if self.sort:
items.sort(options_sorter)
if self.zero != None and not self.multiple:
items.insert(0,('',self.zero))
return items
def __call__(self, value):
if self.multiple:
if isinstance(value, str):
values = [value]
elif isinstance(value, (tuple, list)):
values = value
else:
values = [value]
failures = [x for x in values if not x in self.theset]
if failures:
if self.multiple and value == None:
return (value, None)
return (value, self.error_message)
if self.multiple:
return ('|%s|' % '|'.join(values), None)
return (value, None)
