Javascript objects & methods: what can see what, and why? -

-

i've got set that, in stylised form, this:

(function () {     var db = {         com: {                    edit: changed [...] {...}             324: {                 unmod: "xyz"             }         }     };      var report = {         mymethod: function () {             var x = db.com[324].unmod;         }     }; })();

the error message i'm getting db.com undefined. seems me report.mymethod cannot "see" db.com. right?

one factor might db.com created looping through ajax data this:

    (i = 0; < length1; i++) {             cat = o.cat[i];             length2 = cat.com.length;              // loop through comments             (j = 0; j < length2; j++) {                 com = cat.com[j];                  // create db object                 this[com.cnum] = {                     unmod: com.unmod                 };             }                    }

is issue 1 of closure?

the relevant part of ajax data this

       "cat":[           { ...           "com": [ {"cnum":"324", "unmod":"xyz"},...]           }, ...],

apologies ajax names , property names same. makes easier me, perhaps not y'all :)

example code works expected after fixing population part: http://jsfiddle.net/4bl8t/

django - How can I change user group without delete record -

on website user have 1 group. , user can change group. it's made user.groups.clear() and user.groups.add(new_group) but it's not efficient, because there 2 sql query: delete, insert. how can change group update query? user , group related each other using manytomanyfield . means intersection table exists relating both entities, , if don't specify model map (using through attribute) django creates 1 you. looking @ sources django.contrib.auth.models see that's case. fortunatly, can access intermediary model using through attribute of manager (in case, user.groups.through ). can use regular model. example: >>> alice = user.objects.create_user('alice', 'alice@example.com', 'alicepw') >>> employee = group.objects.create(name='employee') >>> manager = group.objects.create(name='manager') >>> alice.groups.add(employee) >>> alice.groups.all() [<group: employee...

i need set custom soap header attribute on jax-ws generated webservice client. case webservice calls must go through proxy server requiring specific token (recieved web request header) present in soap request header. e.g.: 1 carserviceservice service = null; 2 service = new carserviceservice(new url(url), new qname(qname); 3 carserviceendpoint port = service.getcarserviceport(); it seems in line 3 wsdl retrieved , call fails due missing security token. 1 point direction on how done? a detailed example has been mentioned here: creating , deploying jax-ws web service on tomcat 6 this article shows how create , use security token .
