关联查询实现

1. /application/admin/model/info/User.php模型关联表，绑定字段

   use app\admin\model\Admin;
   

   public function admin()
   {
      return $this->belongsTo(Admin::class, 'admin_id')->setEagerlyType(0)->bind('username');
   }
   

   绑字段也可以关联查询时绑定

   $list = $this->model
       ->with(['admin'])
       ->field('admin.username as username,admin.id as admin_id')
       ->where($where)
        ->order($sort, $order)
        ->limit($offset, $limit)
        ->select();
   

2. /application/admin/controller/info/User.php用->with(['admin'])绑定关联查询

   public function index()
   {
   	//是否是关联查询
      $this->relationSearch = true;
      //设置过滤方法
      $this->request->filter(['strip_tags']);
      if ($this->request->isAjax()) {
          //如果发送的来源是Selectpage，则转发到Selectpage
          if ($this->request->request('keyField')) {
              return $this->selectpage();
          }
          list($where, $sort, $order, $offset, $limit) = $this->buildparams();
          $total = $this->model
              ->with(['admin'])
              ->where($where)
              ->order($sort, $order)
              ->count();
          $list = $this->model
              ->with(['admin'])
              ->field('admin.username as username,admin.id as admin_id')
              ->where($where)
              ->order($sort, $order)
              ->limit($offset, $limit)
              ->select();
          $list = collection($list)->toArray();
          foreach($list as $key=>&$value){
              $value['admin_id'] = $value['username'];
          }
          $result = array("total" => $total, "rows" => $list);
          return json($result);
      }
      return $this->view->fetch('index');
   }
   

/public/assets/js/backend/info/user.js页面绑定selectpage事件

第一种办法

{field: 'admin_id', title: '操作人', addclass:"selectpage", extend:'data-source="auth/admin/index" data-field="username"'},

第二种办法
一定要写在var table1 = $("#table1");下面

//表格加载完成后执行
table.on('post-common-search.bs.table',function(event, table){
 	var form = $("form", table.$commonsearch);
    $("input[name='admin_id']", form).addClass("selectpage").data("source", "auth/admin/index").data('primaryKey', 'id').data("field", 'username').data('orderBy', "id desc");
    Form.events.cxselect(form);
    Form.events.selectpage(form);
})
