Meant to do this for a while as it was irritating me (both the lack of
multilingual support and the "" option when a default is specified).
Pretty much a copy-paste from sqlhtml.OptionsWidget.widget method with
2 improvements (as per the title):
1) The options get translated using the facility provided by T(string)
2) If you specify a default value for the field, the user-confusing ""
doesn't appear in the option-list.
Had to manually add a small bit of code to auto-select the default (I
guess it was implemented in some other part of the code for
OptionsWidget and was lost in the copy-paste).
Not sure if other options I'm not using get lost in the translation,
but it works well with my stuff so far.
If someone else posted a similar solution already, sorry for spamming.
The code:
def MultilingualOptionsWidget(field, value):
default = dict(
value=value,
)
attr = dict(
_id = '%s_%s' % (field._tablename, field.name),
_class = isinstance(field.type,str) and field.type or
None,
_name = field.name,
requires = field.requires,
)
requires = field.requires
if not isinstance(requires, (list, tuple)):
requires = [requires]
if requires:
if hasattr(requires[0], 'options'):
options = requires[0].options()
if field.default != None:
options = options[1:]
else:
raise SyntaxError, 'widget cannot determine options of %s'
\
% field
opts = [(OPTION(T(v), _value=k) if k!=field.default else
OPTION(T(v), _value=k, _selected='selected')) for (k, v) in options]
return SELECT(*opts, **attr)
