Question

我有一个Job模型和一个Visit模型，一个Job可以有很多Visit。我已经在我的模型中适当地建立了关系。

访问也属于Supplier，因此Supplier可以有多次访问。

转包商是数据库中engineer值为0的供应商。

我想返回一个关联数组，其中包含每个转包商募集的作业数量，如下所示：

$supplier_job_count = array(
    'Subcontractor1' => 23,
    'Subcontractor2' => 3,
    'Subcontractor3' => 7,
    'Subcontractor4'=> 0
);

这就是我所拥有的：

    $conditions = array();   

    // get all the visits in the database 
    $visits = $this->Job->Visit->find('all');

    // extract all the visit id's
    $visit_supplier_ids = Hash::extract($visits, '{n}.Visit.supplier_id'); // 11612 records        

    // get all the subcontractors in the database
    $subcontractors = $this->Job->Visit->Supplier->find('all', array('order' => 'id ASC', 'conditions' => array('Supplier.engineer' => 0)));

   // extract all the subcontractor id's
   $subcontractor_ids = Hash::extract($subcontractors, '{n}.Supplier.id'); // 1288 records

   // intersect arrays so we only want matching values from both, i.e. only want visits whose supplier is a subcontractor
    $visit_subcontractors = array_values(array_intersect($visit_supplier_ids, $subcontractor_ids));

    // find all visits who is a subcontractor id
    $visits = $this->Job->Visit->find('all', array('conditions' => array('Visit.supplier_id' => $visit_subcontractors)));

    // extract out the job id's for the subcontractor visits
    $visit_jobs_ids = Hash::extract($visits, '{n}.Visit.job_id');

    // pass the job id's to the conditions for the jobs
    $conditions['Job.id'] = $visit_jobs_ids;

    // get all subcontractor jobs
    $subcontractor_jobs = $this->Job->find('all', array('conditions' => $conditions));
    $subcontractor_job_count = array();

    foreach ($subcontractors as $key => $value) {

       // this is where I am getting stuck
       $subcontractor_job_count[$value['Supplier.name']] = ));
    }

我在那里有一半，只是努力计算每个分包商提出的工作岗位数量，任何想法？
