Re: How underscore works for dropdown?

Hi Juan,

I am waiting for the reply. Below is the description of the web service for forum rating.

I am passing following parameters for calling forum rating

forumid, itemid, scaleid, rating, userid.

It also need cm and context id that I am calculating in the forum rating function. Its working fine if I run from client.php, but when I call the web service from mobile app It gives an error "Invalid parameters are detected." And the message in debug info is "Missing required key in single structure: rate" . There are actually 2 cases: 1. if I pass data"Invalid parameters are detected." error comes. 2. If I pass d  "We lost connection you need to reconnect.Your token is invalid."  However if I call the forum_rating webservice by client.php it works fine.

Below I am sharing the ratepost function code.

ratepost: function(forumId, userid, ratevalue, postid, scaleid ) {
           
            var data = {
            "post[0][forumid]" : forumId,
            "post[0][itemid]" : postid,
            "post[0][scaleid]" : scaleid,
            "post[0][rating]" : ratevalue,
            "post[0][userid]" : userid
            };
            var d = new Array();
            d[0] = data;

            MM.moodleWSCall('local_forum_rating', data, function(resrate) {
                alert("check");                    
            });                         
        }

Forum rating webservice

    public static function forum_rating_parameters() {
        return new external_function_parameters(
                array(
            'rate' => new external_multiple_structure(
                    new external_single_structure(
                    array(
                'forumid' => new external_value(PARAM_INT, 'contextid'),

                    )
                    )
            )
                )
        );
    }

    public static function forum_rating($rate = array()) {
        global $CFG, $DB;

        require_once($CFG->dirroot . '/rating/lib.php');
        $ob = array();
        $params = self::validate_parameters(self::forum_rating_parameters(), array('rate' => $rate));
        $rateperpost = $params['rate'];
        foreach ($rateperpost as $rateonpost) {
            $userrating = $rateonpost['rating'];
            $forumid = $rateonpost['forumid'];
            $cm = get_coursemodule_from_id('forum', $forumid);
            $context = context_module::instance($cm->id);
            if ($userrating != RATING_UNSET_RATING) {
                $ratingoptions = new stdClass;
                $ratingoptions->context = $context;
                $ratingoptions->component = 'mod_forum';
                $ratingoptions->ratingarea = 'post';
                $ratingoptions->itemid = $rateonpost['itemid'];
                $ratingoptions->scaleid = $rateonpost['scaleid'];
                $ratingoptions->userid = $rateonpost['userid'];
                $rating = new rating($ratingoptions);
                $rating->update_rating($userrating);
               // $html[] = (array)$group;
                $html[] = array('rate' => $userrating);
            }
        }
        return $html;
    }

    
    public static function forum_rating_returns() {
        return new external_multiple_structure(
            new external_single_structure(
                array(
                    'rate' => new external_value(PARAM_RAW, 'rating'),
                )
            )
        );
    }

Please let me know why am I unable to call the web service by mobile app? Thanks in advance.
