Hi,
I do not know if this is bug or not but I am not able to get multiselect
widgets to work properly. I have this kind of lines in my table definition:
Field('methodsA', type='string',
requires=IS_IN_SET(['method1','method2','method3'], multiple=True,
zero='<-- choose -->'), widget=SQLFORM.widgets.multiple.widget)
Field('methodsB, type='string',
requires=IS_IN_SET(['method1','method2','method3'], multiple=True,
zero='<-- choose -->'), widget=SQLFORM.widgets.checkboxes.widget)
These correctly translate into select and multiple checkbox widgets both in
my app and admin interface. They also correctly stores my multiple
selections into the database (in form |method1|method2| etc.). However if I
try to modify records later on the edit form does not show previously
selected and stored selections. In form view it looks like previous
selections were empty set! And if I submit the form without selecting
proper list items again the form will store empty set into the database.
I made numerous google searched and found suggestion how this should be
fixed: http://git.net/web2py/msg108396.html. The suggestion applies only to
SQLFORM.widgets.multiple.widget and this small change hasn't been
integrated into web2py source tree yet. Does this small change break
something? This small change seems to fix selection issues in form view. Do
I use gluon.sqlhtml.MultipleOptionsWidget incorrectly or is this real bug?
If I am using this widget inappropriately could someone show me how this
widget should be used. I am also curious to know how
SQLFORM.widgets.checkboxes.widget should be fixed to make it work correctly.
I am using web2py version: 2.9.12-stable+timestamp.2015.03.19.06.51.11 on
linux.
