Parse Server Cloud Code Setting ACL -

-

i try set acls code below, in mongolab database not see acl settings. doing wrong in code? not find tutorial cloud code examples.

    parse.cloud.aftersave('_user', function(req) {      var user = req.user;     var acl = new parse.acl();     acl.setreadaccess(req.user, true);     acl.setwriteaccess(req.user, true);     user.setacl(acl);     user.save();      });       parse.cloud.aftersave('usersetting', function(req) {      var userset = req.object;      var acl = new parse.acl();     acl.setreadaccess(parse.user.current().id, true);     acl.setwriteaccess(parse.user.current().id, true);     userset.setacl(acl);     userset.save();    });

i figured out code below. problem was trying use "aftersave" method while trying adding acl requested object, however, acl should added before saving, or if should done after saving, object should retrieved again , acl should added.

parse.cloud.beforesave('usersetting', function(req, res) {  var acl = new parse.acl(); acl.setreadaccess(req.user, true); acl.setwriteaccess(req.user, true); req.object.setacl(acl); res.success();  });

i use winscp download , edit .scss files , sass on linux (on server) compile them .css . after saving file, use: sass scss/style.scss css/style.css , replaces css file compiled sccs. the problem i want skip part return command line after editing scss file, sake of automation , saving time. but, if use watch command: sass --watch scss/style.scss:css/style.css synchronize 2 files, alerts nonexistent css errors pop up: change detected to: scss/style.scss error scss/style.scss (line 232: invalid css after "...ht: bold; line-": expected "{", "") note that when file uploads quicker usual (sometimes happens) watch command job, no errors. this because, when file upload takes time, sass compiles scss file (on server) before uploaded remote folder. thus, compiles part of file, resulting in css errors. is there way set timer watch command waits few seconds after detects changes , before compiling? any other way overcome is, of course, ...
