CakePHP マニュアルから:
Let's say you had a belongsTo relationship between Posts and Authors. Let's say you wanted to find all the posts that contained a certain keyword ("magic") or were created in the past two weeks, but you want to restrict your search to posts written by Bob:
array (
"Author.name" => "Bob",
"OR" => array (
"Post.title LIKE" => "%magic%",
"Post.created >" => date('Y-m-d', strtotime("-2 weeks"))
)
)
しかし、それは私にとってはうまくいきません。Vargroup に属する Scrapes と、Vargroup hasMany Scrape があります。私のスクラップテーブルにはフィールド vargroup_id があります
私がする時:
$this->Vargroup->contain('Scrape');
$this->Vargroup->find('first');
私は得る:
Array
(
[Vargroup] => Array
(
[id] => 16950
[item_id] => 1056
[image] => cn4535d266.jpg
[price] => 22.95
[instock] => 1
[timestamp] => 2012-10-29 11:35:10
)
[Scrape] => Array
(
[0] => Array
(
[id] => 18163
[item_id] => 1056
[vargroup_id] => 16950
[timestamp] => 2012-05-23 15:24:31
[instock] => 1
[price] => 22.95
)
)
)
しかし、私がするとき:
$this->Vargroup->contain('Scrape');
$this->Vargroup->find('first', array(
'conditions' => array(
'not' => array(
array('Scrape.timestamp >' => $today)
)
)
));
関連するSQL出力で次のエラーが発生します
Warning (512): SQL Error: 1054: Unknown column 'Scrape.timestamp' in 'where clause'
Query: SELECT `Vargroup`.`id`, `Vargroup`.`item_id`, `Vargroup`.`image`, `Vargroup`.`price`, `Vargroup`.`instock`, `Vargroup`.`timestamp` FROM `vargroups` AS `Vargroup` WHERE `Scrape`.`timestamp` = '2012-10-29
テーブルをまったくバインドしているようには見えません..どんな助けでもいただければ幸いです。ありがとう
