RestDataSource and dataURL tweak

[cedric_sis]

Hi,

I am currently on SmartClient Version: v10.0p_2014-10-10/EVAL Development Only

I try to to setup a RestDataSource with REST server app : Django REST Framework.

While it was easy to fetch records or create a new one, I can't find a way to get my RestDataSource to work for others operationType.

To edit or delete a record I need to add the primary key (id) to the dataURL. I am currently focused on the "remove" operation.

dataURL is "/rapi/clients/" and I need to have "/rapi/clients/<id>" when I want to edit/delete a record.

isc.RestDataSource.create({
    ID:"client",
    fields: [
        {name:"id", type:"integer", title:"id"},
        {name:"name", type:"text", title:"Nom", required:true}
    ],
    dataFormat:"json", DSDataFormat:"json",
    sendMetaData: false,
    recordXPath: "data",
    dataURL:"/rapi/clients/",
    transformRequest: function(dsRequest) {
        dsRequest.httpHeaders = {"Accept":"application/json", "X-CSRFToken": CSRFToken};



        if(dsRequest.operationType == "remove") {
            // Add the id to dataURL, how ?
        }

        return this.Super("transformRequest", arguments);
    },
    operationBindings:[
        {operationType:"remove", dataProtocol:"getParams", requestProperties:{httpMethod:"DELETE"}}
    ]
});

Thank you

That's a very bad design, because it prevents combining multiple operations, such as a mixture of updates and adds, into a single HTTP call. Avoid using this design if you can.

If you have no choice, you can simply modify the dataURL on the dsRequest (dsRequest.dataURL = ...).

Thanks you, it's working !

I know it's not the better way to do this. Hopefully I don't need to combine multiple operations for now, and I need to migrate the UI, and just the UI.

If I have success with my app and smartclient I will probably migrate to smartclient on the server side too later ;)
