CRUD Operations on local data - parameterMap not firing

[Darren]

Hey guys,

I have a grid bound to a DataSource which references local data.  The data is loaded with a prior ajax call and is simply re-used in this DataSource to save on a round trip to the server.  The local data is a subset of a larger data set.

I have a need to perform CRUD operations on this local data via a grid.  Prior to sending the payload to the server, I need to map the model to a server-friendly object graph.  I assume the best way to do this is via the transport.parameterMap option.

Here's my grid & DataSource configuration:

grid.kendoGrid({

    dataSource: {

        transport: {

            read: function(options) {

                options.success(filters); // filters is the local array of data

            },

            create: function(options) {

                prime.dsCrud({ url: 'CreateFilters', crud: options });

            },

            update: function (options) {

                prime.dsCrud({ url: 'UpdateFilters', crud: options });

            },

            destroy: function(options) {

                prime.dsCrud({ url: 'DestroyFilters', crud: options });

            },

            parameterMap: function(options, operation) {

                console.log(operation); // *** never fires! ***

            }

        },

        batch: true,

        pageSize: 10,

        schema: {

            model: {

                id: 'id',

                fields: {

                    id: { editable: false, nullable: true },

                    member: { type: 'string', validation: { required: true } },

                    operator: { type: 'number', validation: { required: true } },

                    dataType: { type: 'string', validation: { required: true } },

                    value: { type: 'string', validation: { required: true } }

                }

            }

        }

    },

    sortable: true,

    pageable: true,

    filterable: false,

    editable: true,

    navigatable: true,

    toolbar: ["create", "save", "cancel"],

    columns: [

        {

            field: 'member',

            title: 'Column'

        },

        {

            field: 'operator',

            title: 'Operator'

        },

        {

            field: 'value',

            title: 'Value(s)'

        },

        {

            command: 'destroy',

            title: '',

            width: '170px'

        }

    ]

});

For completeness sake, here is my prime.dsCrud function:

prime.dsCrud = function (options) {

    $.ajax({

        url: prime.data.queryTool + options.url,

        dataType: 'jsonp',

        contentType: 'application/json',

        type: 'POST',

        data: options.crud.data,

        success: function(data, textStatus, jqXHR) {

            options.crud.success(data);

        },

        error: function(jqXHR, textStatus, errorThrown) {

            options.crud.error(jqXHR);

        },

        complete: function(jqXHR, textStatus) {

            console.log('-----------------------------------');

            console.log('response from ' + options.url + ':');

            console.log(jqXHR);

            console.log('-----------------------------------');

        }

    });

}

I realize I could probably do this in the prime.dsCrud function's "data" configuration, but I would prefer to leave this function more generic.  Can anyone explain to me why my transport.parameterMap isn't firing?

Thanks!
