How to exclude an object's id property before or during $.toJSON

问题

I'm writing a custom REST adapter for ember-data users with a django rest framework app and need to build a JSON string to do POST/PUT. The only problem is I can't seem to chain another jQuery method after the $.toJSON that removes this.

So far I have an ember.js object that I plan to extract each property from, except my django app doesn't want the id to go along with the HTTP POST

I can get a legit string like so

$.param(record.toJSON());

This results in the following

id=0&username=dat

I'd like a quick way to exclude id when I do this toJSON (does this exist w/ out writing it by hand?) Using jQuery 1.8+

Thank you in advance

回答1:

Turns out this was really simple

var json_data = record.toJSON();
delete json_data.id;
var data = $.param(json_data);

Now instead of

id=0&username=dat

I now get

username=dat
