Hi
I have Paper and Author in HABTM relation (AuthorsPaper is the join
table model).
If I try to perform a find on the Paper model which involves also the
authors in the condition I get an error since only the papers table is
used for the conditions (even though recursive is set to 1).
Thus, I made an explicit join:
$joins[] = array(
'table' => $this->AuthorsPaper->tablePrefix.$this->AuthorsPaper->useTable,
'alias' => 'AuthorsPaper',
'conditions' =>
array('AuthorsPaper.paper_id = Paper.id AND AuthorsPaper.author_id' =>
$authors)
);
$this->find('all',
array(
'joins' => $joins,
'conditions' => $conditions
)
);
where $conditions includes conditions on papers' fields.
Is this the correct approach?
In particular, I haven't found any "official" documentation on joins but
on some blog posts or on bakery (e.g.,
http://bakery.cakephp.org/articles/view/quick-tip-doing-ad-hoc-joins-in-model-find).
I'm asking since using joins requires specifying an explicit table name
(which can be achieved anyway using tablePrefix and useTable so that it
works also with fixtures in unit tests).
thanks in advance
Lorenzo
