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)
return dict(filtered_sub = filtered_sub)
echo.html
<select id='t_items_f_item_subcategory' class='generic-widget'
name='f_item_subcategory'>
<option value=''></option>
{{for f in filtered_sub:}}
<option value='{{=f.id}}'>test</option>
{{pass}}
</select>
It injects into the target div a whole page (layout.html) and inside, it
renders "ECHO" then the filtered_sub results as a table, + design,
reqwest, response, session, db tables and db stats buttons under it.
