CakePHP查找与'；和''；或'；和'；NOW（）：：date'；

我试图在find中翻译这个查询，但没有成功。我的发现没有返回任何东西

我的SQL（在postgresql中）

我的发现

   $projectversions = $this->find('list', array(
            'recursive' => -1,
            'fields' => array('vname'),
            'conditions' => array('project' => $id_project,'releasedate >=now()::date','OR'=>array('releasedate is null'))));

---

有人能帮我吗？

您原来的选择似乎无效：

select * from projectversion where project='10003' releasedate>=now()::date or releasedate is null

如果是：

select * from projectversion where project='10003' AND (releasedate>=now()::date or releasedate is null)

如果是这样，您的情况应该如下所示：

'conditions'=>array(
    'Model.project'=>10003,
    OR=>array(
        'Model.releasedate >= NOW()'
        'Model.releasedate IS NULL'
    )
)

产生：

WHERE Model.project = 10003 AND (Model.releasedate >= NOW() OR Model.releasedate IS NULL)

WHERE Model.project = 10003 AND (Model.releasedate >= NOW() OR Model.releasedate IS NULL)
