私が持っているもの:
"A" HABTM "C" HABTM "A" through join table "B"
"A" hasMany "B" belongsTo "A"
"C" is ordered by a "B" field
私が欲しいもの:
// result:
[0] => array(
A => array( /* single model's fields I still need*/ ),
C => array(
[0] => array( C.field1, C.field2, ... /* Model C fields*/ ),
[1] => array( C.field1, C.field2, ... )
)
)
私が試したこと:
// this gives me data I don't need:
A->find('all', array( 'conditions' => array( 'id' => $id ) ) )
// result:
[0] => array(
A => array( /* single model's fields I need*/ ),
B => array( /* I DON'T NEED */
[0] => array( ... )
[1] => array( /* ... etc, tons records I don't need */ )
),
C => array(
[0] => array( C.field1, C.field2, ... /* I need these fields*/
[B] => array( /* I DON'T NEED */ )
),
[1] => array( C.field1, C.field2, ... )
[B] => array( /* ... etc, each has a model B I don't need ... */)
)
)
)
Containableを使用すると、クエリをかなり削減できますが、関連するモデルの問題がまだあります。
// this is a little better
A->find('all', array(
'conditions' => array( 'id' => $id ),
'contain' => array( 'C' )
))
// result:
[0] => array(
A => array( /* single model's fields I still need*/ ),
C => array(
[0] => array( C.field1, C.field2, ... /* I still need Model C fields*/
[B] => array( /* I still DON'T need this Model's fields */ )
),
[1] => array( C.field1, C.field2, ...
[B] => array( /* ... still has unneeded model B */)
)
)
)
NB1:私はこれ、これ、これを本から読みました。また、これとこれも読みました。
NB2:私も試しました
C->recursive = -1 // no effect
C->unbindModel(array('hasAndBelongsToMany'=>A)) // no effect
A->find('all', array( // not what I want, but it's still
'conditions' => array('id' => $id), // odd that this doesn't filter C's
'contain' => array('A.B'))); // fields out. same as second result
A->find('all', array( // also not what I want, but it's
'conditions' => array('id' => $id), // weird that this doesn't filter B's
'contain' => array('A.B.field'))); // fields at all;
