Habtm implementation:
Model::_deleteLinks($id)
"Cascades model deletes through HABTM join keys."
I just found out reason why some records gets randomly deleted from
habtm:
cake ignores 'condition' filed in habtm assocciation definition.
example:
var $hasAndBelongsToMany = array(
'Tag' =>
array('className' => 'Tag',
'joinTable' => 'content_tags',
'foreignKey' => 'content_id',
'associationForeignKey'=> 'tag_id',
'conditions' => "content_type='News'",
..
Now, cake will use 'condition' to find results,
but ignore when deleting!
So if you have (in this example) tags for Video,Product,Photo..,
by deleting News with id=1,
cake will delete tags for Product id=1, Video id=1.. and so on.
Delete is often followed by redirect to referrer and hard to debug
sql.
This miss-behavior is in cake 1.x, and, as I can see, in 1.2.x.
You can define 'deleteQuery'=> '' in habtm assocciation but why?
@nate should I open ticket for this?
