I'll follow your advice and paste the relevant code :)
The Region model:
------------------------------------------------
class Region extends AppModel
{
var $name = "Region";
var $validate = array(
'name' => VALID_NOT_EMPTY
);
var $hasMany = array(
'Country' => array(
'className' => 'Country',
'foreignKey' => 'region_id'
)
);
}
The Country model:
------------------------------------------------
class Country extends AppModel
{
var $name = "Country";
var $validate = array(
'name' => VALID_NOT_EMPTY
);
var $belongsTo = array(
'Region' => array(
'className' => 'Region',
'conditions' => '',
'order' => '',
'foreignKey' => 'region_id'
)
);
var $hasMany = array(
'Travel' => array(
'className' => 'Travel',
'foreignKey' => 'country_id'
)
);
}
The add() action in countries_controller:
------------------------------------------------
function add($region_id = null)
{
if (!empty($this->data))
{
$this->data['Country']['region_id'] = $region_id;
if ($this->Country->save($this->data))
{
$this->flash('New country added.', '/countries/index/' .
$region_id, 2);
}
}
else
{
$this->set('region_id', $region_id);
}
}
And the add.thtml view:
------------------------------------------------
<h1>New contry</h1>
<form method="post" action="<?php echo $html->url('/countries/add/' .
$region_id) ?>">
<p><span class="redText">*</span>Country name:
<?php echo $html->input('Country/name', array('size' =>
'25')) ?>
<?php echo $html->tagErrorMsg('Country/name', 'A name is
mandatory.') ?>
</p>
<p>
<?php echo $html->submit('Save'); ?>
</p>
<p>All fields marked <span class="redText">*</span> are mandatory.
</p>
</form>
If thre's something missing, just tell me.
