OneThink视图模型进行组合查询！文档组合文档详情

测试方法：twoCate：

public function twoCate(){
    $where = array(
        'category_id'=>43
    );
    $list = D('TwoView')->where($where)->select();
    p($list);    
}

模型：

<?php
namespace Home\Model;
use Think\Model\ViewModel;

/**
 * 文档基础模型
 */
class TwoViewModel extends ViewModel{ 
    public $viewFields = array(
        'document' => array(
            'id','uid','name','title','update_time',
            '_type' => 'LEFT'
        ),
        'document_article' => array(
            'content',
            '_on' => 'document.id = document_article.id'
        )
    );
}

组合后的列表：

array(3) {
  [0]=>
  array(6) {
    ["id"]=>
    string(1) "7"
    ["uid"]=>
    string(1) "1"
    ["name"]=>
    string(0) ""
    ["title"]=>
    string(15) "医院新闻一"
    ["update_time"]=>

  }
  [1]=>
  array(6) {
    ["id"]=>
    string(1) "8"
