问题
I am using Cakephp 2.4.5. I have 2 tables with a one-to-many relationship. Table B belongs to Table A.
I want a controller in Table A that can save records in Table A and Table B. The controller code should be simple and looks like this;
public function add_tableA($id=null)
{
if ($this->request->is('post'))
{
$this->layout = null ;
$this->TableA->create();
$this->TableA->saveAll($this->request->data, array('deep' => true));
}
}
My problem comes when trying to send the right HTTP POST format to the controller.
I tried to HTTP POST the data format below but it fails.
data[TableA][field1] = field1_value
data[TableA][field2] = field2_value
data[TableB][field1] = field1_value
data[TableB][field2] = field2_value
Then, I try to HTTP POST the data format below, at least TableA fields are populated.
data[TableA][field1] = field1_value
data[TableA][field2] = field2_value
How should the HTTP POST data format look like if I want to create rows for both tables?
回答1:
See: http://book.cakephp.org/2.0/en/models/saving-your-data.html
and example for saveAssociated:
$data = array(
'Article' => array('title' => 'My first article'),
'Comment' => array(
array('body' => 'Comment 1', 'user_id' => 1),
array('body' => 'Comment 2', 'user_id' => 12),
array('body' => 'Comment 3', 'user_id' => 40),
),
);
So, in your case post something like
data[TableA][field1] = field1_value
data[TableA][field2] = field2_value
data[TableB][0][field1] = field1_value
data[TableB][0][field2] = field2_value
data[TableB][1][field1] = field1_value
data[TableB][1][field2] = field2_value
etc
and:
$this->TableA->saveAssociated($this->request->data);

In order to save it like that you need to have:
data[TableB][TableA_id] = 'id of data saved be to TableA';
for TableB data to be saved. So I think you need to first save TableA:
$dataA = $this->TableA->save('data for TableA');
if (!$dataA) {
$data['TableB']['TableA_id'] = $this->TableA->id;
$this->TableA->TableB->save('data array for TableB');
}
