def echo():
value = request.post_vars.f_item_category
filtered_sub = db(db.t_sub_categories.f_category_id ==
value).select(db.t_sub_categories.ALL,orderby=db.t_sub_categories.f_sub_category_name,
cache=(cache.ram,10),cacheable=True)
filtered_sub = dict(filtered_sub = filtered_sub)
select_header = "<select id='t_items_f_item_subcategory'
class='generic-widget' name='f_item_subcategory'> \
<option value=''></option>"
select_footer = '</select>'
def select_body():
for f in filtered_sub:
#return "<option value='f.id'>" + f.f_item_subcategory +
"</option>"
return 'test'
return select_footer + select_body() + select_footer
This will render 'test' just once(where expected more).
I think the problem is that the filtered_sub = dict() from some reason.
If I replace the return 'test' with:
return "<option value='f.id'>" + f.f_item_subcategory + "</option>"
It flashes an error.
Thanks.
