记录：fastadmin表格数据逗号分隔的id关联展示数据名称并实现搜索

1，在查询后增加显示代码


$fields = [['field'=>'tags_ids', //关联数据字段'display'=>'tags_name', //附加的字段名称'primary'=>'id', //关联表主键'column'=>'tags_name', //关联表中读取需要显示的字段'model'=>'', //关联模型'table'=>'fa_litestore_tags' //关联表，关联表和关联模型二选一]
];
addtion($list,$fields); //list是数组
// addtion($list->items(),$fields); // list是对象

2，增加搜索功能代码

// 特殊搜索处理
$wheres = [];
$filter = json_decode($this->request->get('filter'), true);
$op = json_decode($this->request->get('op'), true);
if(!empty($filter['tags_name'])){$keyword = $filter['tags_name'];$tagsIds = implode(',', Db::name('litestore_tags')->where(['tags_name'=>['like',"%$keyword%"]])->column('id'));$rex = explode(',', $tagsIds);foreach ($rex as $v){$wheres[] = ['exp',Db::raw("FIND_IN_SET('$v', tags_ids)")];}unset($filter['tags_name']);unset($op['tags_name']);
}
$this->request->get(['filter'=>json_encode($filter)]);
$this->request->get(['op'=>json_encode($op)]);

3，完整示例

/*** 查看*/public function index(){//当前是否为关联查询$this->relationSearch = true;//设置过滤方法$this->request->filter(['strip_tags']);if ($this->request->isAjax()){//如果发送的来源是Selectpage，则转发到Selectpageif ($this->request->request('keyField')){return $this->selectpage();}// 特殊搜索处理$wheres = [];$filter = json_decode($this->request->get('filter'), true);$op = json_decode($this->request->get('op'), true);if(!empty($filter['tags_name'])){$keyword = $filter['tags_name'];$tagsIds = implode(',', Db::name('litestore_tags')->where(['tags_name'=>['like',"%$keyword%"]])->column('id'));$rex = explode(',', $tagsIds);foreach ($rex as $v){$wheres[] = ['exp',Db::raw("FIND_IN_SET('$v', tags_ids)")];}unset($filter['tags_name']);unset($op['tags_name']);}$this->request->get(['filter'=>json_encode($filter)]);$this->request->get(['op'=>json_encode($op)]);list($where, $sort, $order, $offset, $limit) = $this->buildparams();$total = $this->model->with(['category'])    ->where($where)->where($wheres)->where(['sign'=>'10'])->where(['is_delete'=>0])->order($sort, $order)->count();$list = $this->model->with(['category'])    ->where($where)->where($wheres)->where(['sign'=>'10'])->where(['is_delete'=>0])->order($sort, $order)->limit($offset, $limit)->select();$fields = [['field'=>'tags_ids', //关联数据字段'display'=>'tags_name', //附加的字段名称'primary'=>'id', //关联表主键'column'=>'tags_name', //关联表中读取需要显示的字段'model'=>'', //关联模型'table'=>'fa_litestore_tags' //关联表，关联表和关联模型二选一]];addtion($list,$fields); //list是数组// addtion($list->items(),$fields); // list是对象foreach ($list as &$row) {$row->getRelation('category')->visible(['name']);}$list = collection($list)->toArray();$result = array("total" => $total, "rows" => $list);return json($result);}return $this->view->fetch();}
