CakePHP 在 hasMany 关系中搜索
我有一个模型内容，它属于类别，有许多发布商，并且发布商属于城市。 还有一个搜索表单，用户可以从下拉框中选择要查看的类别和城市。
但如何将这两者结合在一个分页条件中呢？我的意思是我不能做类似的事情：
$this->paginate('Content',array('conditions' =>array('Category.id'=>$category,
'City.id'=>$city)));
因为要获取城市蛋糕会执行不同的查询。
我也不能做类似的事情：
$this->paginate('Content',array('conditions' =>array('Category.id'=>$category),
'contain'=>array('Publisher.City'=>array('conditions'=>array(City.id'=>$city)))));
因为这将根据类别搜索并根据 $city 过滤城市结果。
我知道我可以做类似的事情：
$this->Content->Publisher->City->find(...)
但这会改变分页数据的输出。
我通常做的是编写自定义查询，其中我左连接所有模型并在 WHERE 中过滤结果。但我想问是否有更多的蛋糕（原文如此）的方式！
谢谢
I have a model Content which belongsTo Categories, hasMany Publishers, and Publisher belongsTo city.
There is also a search form where someone selects from a drop-down box which category to view and which city.
But how can I combine these two in a single paginate condition? I mean I cannot do something like:
$this->paginate('Content',array('conditions' =>array('Category.id'=>$category,
'City.id'=>$city)));
because to get cities cake performs a different query.
Nor can I do something like:
$this->paginate('Content',array('conditions' =>array('Category.id'=>$category),
'contain'=>array('Publisher.City'=>array('conditions'=>array(City.id'=>$city)))));
because this will search according to category and filter the city results according to $city.
I know I can do something like:
$this->Content->Publisher->City->find(...)
but this will change the output of my paginated data.
What I usually do is write my custom query where I LEFT join all models and filter the results in WHERE. But I wanted to aks if there is a more cake (sic) way!
thanks

当我第一次尝试创建一个具有多种关系的简单搜索引擎时，我也经历过同样的事情。
我使用了多个
$this->find()并将其分配在一个变量中，然后在我使用的分页代码上$this->paginate(array_merge($ 中使用的变量的名称)这->find()));。希望这会帮助你......

i've experienced the same thing when i first try to create a simple search engine with hasmany relationship.
i used multiple
$this->find()and assigned it in a variable then on the paginate code i used$this->paginate(array_merge(name of the variables used in $this->find()));.hope this will help you...
