I have 2 select boxes. I managed to auto-populate second select box based
on value from the first one. All of the code below works just fine when I
create new record - second select is being populated. However, when I try
to update the same record, select_2 does not get populated, as if the *
department* variable never reached the *populate* function. As a result,
there's a view rendered within select_2 instead of <option></option>
elements. This occurs only in the update form.
The script passing *department *variable from select_1:
<script>
$('#select_1').change(function() {
ajax('populate', ['department'], 'select_2');
});
</script>
*populate *function which uses "department" var to get respective data:
def populate():
ranks = db(db.rank.department_id ==
request.vars.department).select(db.rank.id, db.rank.name,
orderby=db.rank.name)
result = ""
for r in ranks:
result += "<option value='" + str(r.id) + "'>" + r.name +
"</option>"
return XML(result)
view:
<div class="w2p_fw">
{{if request.vars.department:}}
<select class="generic-widget" id="seafarer_experience_rank"
name="rank">
{{=XML(result)}}
</select>
{{else:}}
{{=form.custom.widget.rank}}
{{pass}}
</div>
