Model Associations will not work for client proxies

[bluehipy]

I was trying to use model with associations on a flow that only use localstorage and I realized that it is impossible.

HasMany association is forcing filtering remote. You can resolve this by passing in association config store:{remoteFiltering:false} but there is also forced modelDefaults with foreignKey: me.get(primaryKey), and this one is made like this:

modelDefaults[foreignKey] = me.get(primaryKey);

                config = Ext.apply({}, storeConfig, {
                    model        : associatedModel,
                    filters      : [filter],
                    remoteFilter : true,
                    modelDefaults: modelDefaults
                });

So it is practically impossible to use HasMany association with client filtering and you will end having all the records in the associated model updated to have the associated.foreignKey = owner.primaryKey, because of the forced modelDefaults

I guess it should be specified that Association are working only with remote filtering, so with server proxies. (at least by default)

Some fixing (?)

hasMany: {
            model: 'MyApp.model.Book',
            autoLoad: true,
            foreignKey: 'id_author',
            store: {
                remoteFilter: true,
                modelDefaults: false,
                proxy: {
                    type: 'maskingproxy',
                    maskedStore: 'Books'
                }
            }
        }

Ext.define(
'MaskingProxy',
 {
   extend:'Ext.data.proxy.LocalStorage',
   alias:'proxy.maskingproxy',
   config:{
      maskedStore:false,
   },
    read: function(operation, callback, scope) {
	   
	   var filters = operation.getFilters();
           
	   var store = Ext.StoreManager.lookup( this.getMaskedStore() );
	   store.clearFilter(true);
	   store.setFilters(filters);

          //I know my store is loaded :P

	  var rec = store.getRange(0,store.getCount()-1);
	  operation.setSuccessful();
	  operation.setCompleted();
	  operation.setResultSet(Ext.create('Ext.data.ResultSet', {
            records: rec,
            total  : rec.length,
            loaded : true
        }));
        operation.setRecords(rec);
	  callback.call(scope,operation);
	  
	}
 }
);
