Yeah, I'm stuck. I don't know how to pass the request.vars.dpt correctly to
my LOAD component.
Here's what I have now:
controller
def add_experience():
add_experience = crud.create(db.seafarer_experience, next=(URL('seafarer',
'profile')), _class='formstyle')
return dict(add_experience=add_experience,dpt=request.vars.dpt)
rank_populate.load
{{if dpt:}}
{{ranks = db(db.rank.department_id == dpt).select(orderby=db.rank.name)}}
{{for r in ranks:}}
{{=OPTION(r.name, _value=r.id)}}
{{pass}}
view
<div class="w2p_fw">
<select class="generic-widget" id="seafarer_experience_rank"
name="rank">
{{=LOAD('seafarer','rank_populate.load',ajax=True, vars={'dpt':
request.vars.dpt})}}
</select>
</div>
I tried vars={'dpt': dpt} also - and nothing. I'm confused.
