从CakePHP手册:
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"))
)
)
然而,它不适合我。我有Scrapes属于Vargroup,Vargroup有很多Scrape。我的scrapes表有一个字段vargroup_id
当我这样做时:
$this->Vargroup->contain('Scrape');
$this->Vargroup->find('first');
我明白了:
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
)
)
)
但是当我这样做时:
$this->Vargroup->contain('Scrape');
$this->Vargroup->find('first', array(
'conditions' => array(
'not' => array(
array('Scrape.timestamp >' => $today)
)
)
));
我得到以下错误以及相关的sql输出
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
它看起来不像它对表的绑定...... 任何帮助,将不胜感激。 谢谢
答案 0 :(得分:0)
试试这个:
$this->Vargroup->contain('Scrape');
$this->Vargroup->find('first', array(
'conditions' => array(
'not' => array(
'Scrape.timestamp >' => array($today)
)
)
));
我认为来自cakephp页面的这个例子说明了做出“不”条件的正确方法, 看看吧。
array(
"NOT" => array("Post.title" => array("First post", "Second post", "Third post"))
)
如果您有更多问题,这是复杂的查找条件页面。 Cakephp complex find conditions
