Hi,
I don't think I have seen this covered in the groups so far, so I
thought I would ask a question...
First off I am quite new to Cake but not PHP. I have designed a
database, which has one table (pages) that is intended to be
heirarchical. I.e. a page can have one or many sub pages.
So that it can represent the following:
Main Page
| - Sub Page 1
| - Sub Page 2
| -Sub Sub Page 1
| - Sub Page 3
The table has a foreign key parent_page_id.
And I have defined a $hasMany relationship which is as follows...
// content_item has many other pages below it
var $hasMany = array('Page' =>
array('className' => 'Page',
'conditions' => '',
'order' => 'Page.order ASC',
'limit' => '',
'foreignKey' => 'parent_page_id',
'dependent' => false,
'exclusive' => false,
'finderSql' => 'Page.parent_page_id
= Page.id'
)
);
But I tested this using the scaffolding and I get this error lots:
Warning: Invalid argument supplied for foreach() in
/var/www/cake/cake/libs/view/templates/scaffolds/view.thtml on line 179
Does anyone know if I am implementing this wrong? or doesn't cake
support recursive relationships?
Thanks in advance.
James
