[3.1] Direct Store with API, Update action takes no parameters

[migolo]

Hi again.

I configured a Direct Store with API actions, in Ext 3.0 everything was working perfectly, when I upgraded to 3.1, the "update" action isn't sending the parameters:

Here is the Request payload with version 3.1:

{"action":"Productos","method":"modificar","data":[],"type":"rpc","tid":11}

And the response:

{"type":"exception","tid":11,"message":"Not enough required params specified for method: modificar on class Productos"}

In version 3.0.0 the Request payload is:

{"action":"Productos","method":"modificar","data":["3","{\"id\":\"3\",\"nombre\":\"Tangram 1, aktuell Lektion 5-8\",\"precio\":481,\"cantidad\":\"5\"}"],"type":"rpc","tid":10}

And the response is:

{"type":"rpc","tid":10,"action":"Productos","method":"modificar","result":{"id":"3","nombre":"Tangram 1, aktuell Lektion 5-8","precio":481,"cantidad":5}}

I am using the same application only testing with the newer version, this is how I configured the store and was working in version 3.0.0 and isn't in 3.1

 var productos_writer = new Ext.data.JsonWriter({
    writeAllFields: true // write all fields, not just those that changed
});

Productos = new Ext.data.DirectStore({
    api: {
        read: Migolo.Productos.listar,
        update: Migolo.Productos.modificar
    },
    paramOrder: ['buscar','start'],
    baseParams: {
        buscar: ""
    },
    autoLoad: true,
    root: "data",
    reader: new Ext.data.JsonReader({
        totalProperty: 'totalCount',
        idProperty: 'id',
        root: 'data'
    }, [{
        name: 'id',
        mapping: 'id'
    },{
        name: 'nombre',
        mapping: 'nombre'
    },{
        name: 'precio',
        mapping: 'precio'
    },{
        name: 'cantidad',
        mapping: 'cantidad'
    }]),
    writer: productos_writer
});

I must say that the "read" action is working in both versions sending the right params.

Best regards, and sorry for my English.

Hi Miguel, I am also experiencing the same issue.

The 'update' action is firing but with empty data (It was working in 3.0.3).

I do not know why however...

[vinnybozz]

I tracked down the problem and it seems to occur in the save method of the Ext.data.Store class definition (around line 20125):

        len = queue.length;
        if(len){
            batch = ++this.batchCounter;
            for(var i = 0; i < len; ++i){
                trans = queue[i];	
                console.debug(trans); // #### ADDED THIS
                data[trans[0]] = trans[1];
            }
console.debug(data); // #### ADDED THIS
            if(this.fireEvent('beforesave', this, data) !== false){
                for(var i = 0; i < len; ++i){
                    trans = queue[i];
                    this.doTransaction(trans[0], trans[1], batch);
                }
                return batch;
            }
        }

When testing within my own program:
trans contains the following array:

["update", [Object {  id="3855",  more...}]]

However, it seems like data[trans[0]] = trans[1]; is not working since when I output data, I get the following:
Object { update=}
As if trans[1] was empty

That's just a display error in Firebug.

Try using:

console.dir(data);

Hi Condor, you're right, the data object now seems to contain the correct information.

The data is still not being sent though, I'll keep trying to find something (using console.dir now !! )

This works in 3.1.x:

  var writer = new Ext.data.JsonWriter
  ({
    encode: false,  // Very important, defaults to true
    writeAllFields : true
  });
  var reader = new Ext.data.JsonReader
  ({
    root            : 'records',
    idProperty      : 'event_person_id',
    totalProperty   : 'totalCount',
    successProperty : 'success',
    messageProperty : 'message',
    
    fields          : recordFields
  });
  var proxy = new Ext.data.DirectProxy
  ({
    api :
    {
      read:   Zayso.Direct.Event_EventPerson.read,
      create: Zayso.Direct.Event_EventPerson.create,
      update: Zayso.Direct.Event_EventPerson.update
    },
    paramsAsHash: true
  });
  var gridStore = new Ext.data.DirectStore
  ({
    // These all come from Store
    storeId     : 'referee-signup-grid-store',
    baseParams  : { event_id : this.eventId, base2: 'somthing' },
    autoLoad    : false,
    autoSave    : false,
    
    remoteSort  : false,
    sortInfo    : { field : 'position_id', direction : 'ASC'},
    
    writer      : writer,
    reader      : reader,
    proxy       : proxy
  });

Try setting encode to false.

And I always use paramsAsHash which ends up sending all the parameters in one array. The direct functions use a len of 1.

Hi again,

Cerad, compring your code, I changed the writer to do an encode: false, and yes, it sends the data, so i think there is a problem with the encode function because I tried setting it to true and the update function sent empty data.

[cerad]

Unless you have a burning desire to encode the data then just leave it false.

[migolo]

I can manage that, a thing I didn't saw before is that the request is sent in a different way:

I get this:

{"action":"Productos","method":"modificar","data":[{"buscar":"","data":{"id":"3","nombre":"Tangram  1, aktuell  Lektion 5-8","precio":480,"cantidad":"5"}}],"type":"rpc","tid":10}

Instead of this:

{"action":"Productos","method":"modificar","data":["3","{\"id\":\"3\",\"nombre\":\"Tangram 1, aktuell Lektion 5-8\",\"precio\":480,\"cantidad\":\"5\"}"]
,"type":"rpc","tid":10}

I only added the encode: false
