ExtJS 4.1 - Returning Associated Data in Model.Save() Response

Question

I am curious as to why the record contained in the result set of a Model.save() response does not properly return updated associated data, despite the updated d

Answer 1

In ExtJS 6.2 the problem still (or again exists). My solution:

/**
 * In Ext.data.reader.Reader::extractRecord the call readAssociated reads out the hasMany associations and processes them.
 * This works perfectly for Model.load() since internally a Model is used as record variable in extractRecord. 
 * For Model.save() record extractRecord contains just the Object with the received data from the PUT request, 
 *  therefore readAssociated is never called and no associations are initialized or updated.
 * The following override calls readAssociated if necessary in the save callback.

Ext.override(Ext.data.Model, {
    save: function(options) {
        options = Ext.apply({}, options);
        var me = this,
            includes = me.schema.hasAssociations(me),
            scope  = options.scope || me,
            callback,
            readAssoc = function(record) {
                //basicly this is the same code as in readAssociated to loop through the associations
                var roles = record.associations,
                    key, role;
                for (key in roles) {
                    if (roles.hasOwnProperty(key)) {
                        role = roles[key];
                        // The class for the other role may not have loaded yet
                        if (role.cls) {
                            //update the assoc store too                            
                            record[role.getterName]().loadRawData(role.reader.getRoot(record.data));
                            delete record.data[role.role];
                        }
                    }
                }

            };

        //if we have includes, then we can read the associations
        if(includes) {
            //if there is already an success handler, we have to call both
            if(options.success) {
                callback = options.success;
                options.success = function(rec, operation) {
                    readAssoc(rec);
                    Ext.callback(callback, scope, [rec, operation]);
                };
            }
            else {
                options.success = readAssoc;
            }
        }
        this.callParent([options]);
    }
