Hi Matt,
I ended up creating a special set of functions for this.
afterFind() calls _afterFind()
_afterFind() locates the data and calls doAfterFind()
This works for what I use afterFind for.
I will only have one place to edit if the data-structires change or I
find I have missed something.
It makes my models a lot more readable.
The relevant code if you should find it useful:
in SomeModel:
// this just calls the "real" afterFind
function afterFind($data, $primary) {
return $this->_afterFind($data, $primary);
}
// receives data as a flat array of fields, no Modelname or anything.
// run from _afterFind splits datetime-field sendat into senddate and
sendtime
function doAfterFind($data) {
if ( !isset($data['senddate']) ) {
$timestamp = strtotime($data['sendat']);
$data['senddate'] = date('Y-m-d', $timestamp);
$data['sendtime'] = date('H', $timestamp);
}
return $data;
}
// AppModel::_afterFind()
function _afterFind($data, $primary) {
if ( $primary ) {
foreach ( $data as $key => $val ) {
if ( isset($val[$this->alias]) ) {
$data[$key][$this->alias] = $this->doAfterFind( $data
[$key][$this->alias] );
}
}
} else {
if ( isset($data['id']) ) {
$data = $this->doAfterFind( $data );
} else {
foreach ( $data as $key => $val ) {
if ( isset($val[$this->alias]) ) {
if ( isset($val[$this->alias]['id']) ) {
$data[$key][$this->alias] = $this->doAfterFind
( $data[$key][$this->alias] );
} else {
foreach ( $data[$key][$this->alias] as $key2
=> $val2 ) {
$data[$key][$this->alias][$key2] = $this-
>doAfterFind( $data[$key][$this->alias][$key2] );
}
}
}
}
}
}
return $data;
}
