cakephp：使用saveAll（），导入（非表单相关）关联数据不保存

Question

My question relates to pulling data from a remote source and saving it to a local database. With the saveAll(), the parent data gets saved correctly, but not the child data.

protected function _saveLocal($_rekeyedData) {
        //Set the invoice header and line items models
        if (!isset($this->LocalHeader)) {
            $this->loadModel('LocalHeader');
            $this->LocalHeader->create();
//            $this->LocalHeader->set($_rekeyedData);
            if (!isset($this->LocalDetail)) {
                $this->loadModel('LocalDetail');
                $this->LocalDetail->create();
            }
        }

        if ($this->LocalHeader->saveAll($_rekeyedData, array('validate' => 'first'))) {
            $this->Session->setFlash('Your data has been saved.');
        } else {
            $this->Session->setFlash('Data load failed.');
        }
        debug( $this->LocalDetail->invalidFields() );
    }

In this function, I load the models, then attempt to saveAll(). A sample record looks like this:

[1] => Array
    (
        [LocalHeader] => Array
            (
                [SOPNUMBE] => CR014076             
                [DUEDATE] => 2012-04-10 00:00:00
                [DOCDATE] => 2012-04-10 00:00:00
                [DOCAMNT] => 12000.00000
                [SUBTOTAL] => 12000.00000
            )

        [LocalDetail] => Array
            (
                [0] => Array
                    (
                        [ITEMNMBR] => BASIC SERVICE                  
                        [QUANTITY] => 1.00000
                        [UOFM] => EA       
                        [UNITPRCE] => 12000.00000
                        [TAXAMNT] => .00000
                        [CONTSTARTDTE] => 1900-01-01 00:00:00
                        [CONTENDDTE] => 1900-01-01 00:00:00
                        [SOPNUMBE] => CR014076             
                    )

            )

    )

All that gets saved is the LocalHeader record. My hunch is that it has something to do with the array('validate' => 'first'). I think I need to do something separate like validateMany when using saveAll(), but I can't remember where I saw something like that or if I just made it up.

I've read many of the related questions in SO, but none of the offered solutions worked for me.

Any help is appreciated. Please feel free to ask if you have any questions.

EDIT: This is the header model and this is the detail model.

I think the issue is that neither of those records exists yet. According to the docs

If neither of the associated model records exists in the system yet (for example, you want to save a new User and their related Profile records at the same time), you’ll need to first save the primary, or parent model.

You can read more here with an example.
