I'm using *the same* web2py_component() function in 3 different forms in my
application. In 2 cases the function gets the job done. In the third form
web2py_component() doesn't work - no request is being sent.
Do you guys know any reason why web2py_component() wouldn't get triggered?
CODE
---------
1. User selects a department from drop box
<select class="generic-widget" id="seafarer_experience_department" name=
"department" onchange="updateranks(jQuery('[name=department]').val());">...
</select>
2. Depatment value gets processed by script generated like this:
_id = "%s_%s" % (field._tablename, field.name)
script = SCRIPT("""
function updateranks(departmentId) {
web2py_component("%(url)s/" + parseInt(departmentId)" +
"?v=%(var)s", "%(_id)s");
}
""" % dict(_id=_id,
url=URL("seafarer", "populate"),
var=field._tablename))
3. The script above sends request to *populate* function. The function
returns respective ranks, based on the department value chosen:
def populate():
if request.vars.v:
tablename = request.vars.v
db[tablename].rank.requires =
IS_IN_DB(db(db.rank.department_id==request.args(0)), 'rank.id', '%(name)s',
zero=None)
form = SQLFORM(db[tablename])
text = "".join([t.xml() for t in
form.custom.widget.rank.elements("option")])
return text
