django deep serializers

Django has it's own very nice serialization module. A very useful tool to serialize models in django projects. There is limitation to it, though.
When one serialize a model (table) which has relationship (ForeignKey) to other model, then you will only get the foreign_key, instead the whole object. Something like the following:

[ {
    "pk": 1,
    "model": "store.book",
    "fields": {
        "name": "Mostly Harmless",
        "author": 42
    }
} ]

In some cases, deep serializing is often necessary. Now, let me introduce you to this magnificent python module which extends django's built-in serializers. DjangoFullSerializers.
With this, you can get something like the following:

[ {
    "pk": 1,
    "model": "store.book",
    "fields": {
        "name": "Mostly Harmless",
        "author": [ {
             "pk": 42,
             "model": "store.author",
             "fields": {
                  "name": "John Doe",
                  "title": "Dr."
             }
        } ]
'    }
} ]

I have used it and really satisfied with the result. Many thanks to the developer.

Serialize Form to JSON

I came across a handy javascript function to serialize form to JSON, taken from here

$.fn.serializeObject = function()
{
   var o = {};
   var a = this.serializeArray();
   $.each(a, function() {
       if (o[this.name]) {
           if (!o[this.name].push) {
               o[this.name] = [o[this.name]];
           }
           o[this.name].push(this.value || '');
       } else {
           o[this.name] = this.value || '';
       }
   });
   return o;
};

add above script to your document, then if you are using jQuery you can just do something like the following:

$("form#data").serializeObject();

and as per need, simply use json2.js to convert the (JSON) form object into string:

JSON.stringify($("form#invite_users").serializeObject());
