Some progress...
I just make a check and chosen plugin multiple select option return a
unordered list of the picked element by the user...
So, now, I think that it could be nice if web2py allow some way to
determine in case of use of chosen kind of plugin to store a unordered list
in list:reference field...
I think that it is near line 207 (web2py 1.99.4) gluon/sqlhtml that we have
to make change :
class OptionsWidget(FormWidget):
@staticmethod
def has_options(field):
"""
checks if the field has selectable options
:param field: the field needing checking
:returns: True if the field has options
"""
return hasattr(field.requires, 'options')
@classmethod
def widget(cls, field, value, **attributes):
"""
generates a SELECT tag, including OPTIONs (only 1 option allowed)
see also: :meth:`FormWidget.widget`
"""
default = dict(value=value) # HERE!!!!!!!!
I am not pretty sure actually... And I don't really know, what could be
done to keep submit multiple list order in case of plugin use...
I try naively to replace
default = dict(value=value)
By
defautl = value
But it failed.
