How the save(CRUD) operation is performed in the Restful table? I request someone to help me on this one?

I had overridden the save of the backbone.js and passed the value to the attribute and it worked. Below is the code for that save(as well as for the update) operation.

AJS.RestfulTable.EntryModel = Backbone.Model.extend({
    /**
     * Overrides default save handler to only save (send to server) attributes that have changed.
     * Also provides some default error handling.
     *
     * @override
     * @param attributes
     * @param options
     */
    save: function (attributes, options) {
attributes.projectKey = dataProjectKey;
console.log("console 4:",attributes.projectKey);
        options = options || {};

        var instance = this,
            Model,
            syncModel,
            error = options.error, // we override, so store original
            success = options.success;

        // override error handler to provide some defaults
        options.error = function (model, xhr) {

            var data = $.parseJSON(xhr.responseText || xhr.data);

            instance._serverErrorHandler(xhr);

            // call original error handler
            if (error) {
                error.call(instance, instance, data, xhr);
            }
        };

        // if it is a new model, we don't have to worry about updating only changed attributes because they are all new
        if (this.isNew()) {
            // call super
            Backbone.Model.prototype.save.call(this, attributes, options);

        // only go to server if something has changed
        } else if (attributes) {
            // create temporary model
            Model = Backbone.Model.extend({
                url: this.url()
            });
            console.log("Temporary Model is :",Model);


            syncModel = new Model({
                id: this.id
            });

            options.success = function (model, xhr) {

                // update original model with saved attributes
                instance.clear().set(model.toJSON());

                // call original success handler
                if (success) {
                    success.call(instance, instance, xhr);
                }
            };

            // update temporary model with the changed attributes
            syncModel.save(attributes, options);
        }
    }
});

You'll need to explain what the Restful table is for most of us.  Although from what I've read (assuming you're using the one google points to) it should handle it automatically.

I think you also need to explain where you are stuck

Now I'm completely lost. 

You say it's handling it automatically, so there's no problem.  So what is the actual question?

Since it is handling the crud operations automatically, i couldn't find a solution for it. my problem is during save i need to hardcode a value of an column in that table. how to bind the value?

Sorry, I'm still lost.  If it's doing the CRUD for you, what's the problem?  If you need to "hard code" a value, then set it in your code, just don't ask the user for it.
