Error using visualForce Remoting for javascript call to custom apex controller RemoteAction

Question

I am trying to call a custom apex controller from javascript code in my visual force page but keep getting the following error :

 Visualforce Remoting Exception: No such column '_name' on sobject of type facture__c 

Here's the javascript call :

   var createFacture = function() {
          var facture = new SObjectModel.Facture();
          var factureReferenceField = document.getElementById('facture-reference');
          var factureClientField = document.getElementById('select-client');
          facture.Reference__c = factureReferenceField.value ;
          facture.Client__c = factureClientField.value;
          console.log(facture);

        Visualforce.remoting.Manager.invokeAction(
            //Invoking controller action getcon
            '{!$RemoteAction.TestController.saveFacture}',
             facture, factureLines,
            function(result, event){
                console.log("in callback func");   
                console.log(event.status);
                console.log(event.message);
            },
            {escape: true}
        );


         console.log('hell yeah');                          
      }

and here's the apex controller method Im trying to call :

@RemoteAction
public static Facture__c saveFacture(Facture__c facture, Ligne__c[] lines) {
    // Perform isUpdatable() checking first, then
    System.debug('facture: '+ facture);
    System.debug('lines: '+ lines);
    upsert facture;
    for(Ligne__c line : lines) {
        line.facture__c = facture.Id;
        upsert line;
    }
    return facture;
}

I ve made the full code of the page and the controller available on github if you need to see more :

How to fix this error and make my remote call work ?

Answer 1

apex:remoteObjects provides a JS-only interface; you can use this to perform DML operations and queries without Apex.

For a remote action method, you'd use a simple object:

var facture = { };
...
facture.Reference__c = factureReferenceField.value;
facture.Client__c = factureClientField.value;
    Visualforce.remoting.Manager.invokeAction(
        //Invoking controller action getcon
        '{!$RemoteAction.TestController.saveFacture}',
         facture, ...

Answer 2

The structure of the instance created from sObjectModel will be different from the actual structure of your object. Hence, you cannot perform DML on that instance in your remote action method, that is the reason you are getting the above mentioned error. You can refer this link from Salesforce documents to understand more on the structure created using sObjectModel (It creates a attribute containing comma separated API names of fields and not attributes for each field)

If you want to create a record from javascript, you can use the create method of Remote Object. You can find further help on this topic in this link

You can use the callback function of the create method and send the ID of the record to your controller for any further actions.
