Thanks a lot Val that's certainly the solution, however in the controller
the var is always empty.
This is the original select code:
<select name='ceo_scheme' onchange="$('#overrides').empty(); ajax('{{=URL('
default','get_options_for_overrides')}}', ['ceo_scheme'], 'overrides');">
If I set manually the var in get_options_for_overrides the ajax call works.
For debug, if I modify get_options_for_overrides for
returning get_options_for_overrides.vars.ceo_scheme the target select
'override' is empty.
My original controller:
def get_options_for_overrides():
ceo_scheme_id = get_options_for_overrides.vars.ceo_scheme
overrides = db(db.ceo_schemes_and_overrides.ceo_scheme == ceo_scheme_id
).select(db.ceo_schemes_and_overrides.ALL)
html = ''
for override in overrides:
html += '<option value=' + str(override.override.id) + '>' +
override.override.name + '</option>' + '\r\n'
return html
My controller for debug:
def get_options_for_overrides():
ceo_scheme_id = get_options_for_overrides.vars.ceo_scheme
return ceo_scheme_id
Do you know why?
Regards.
