关于Laravel-admin的基础用法总结和自定义model详解

当列表数据获取有特定条件或自己写ORM方法时可以用到，支持排序
$grid->model()->select('id','name')->where('status',1)->groupBy('project_id');
$grid->model()->select('id','name')->where('status',1)->groupBy('project_id');
//结合having 查出名字重复的
$grid->model()->select('name_en')->groupBy('name_en')->havingRaw('count(name_en)>1')
//嵌套子查询 查出名字重复的全部信息
$grid->model()->select('id','name_en')->whereIn('name_en',Project::select('name_en')->groupBy('name_en')->havingRaw('count(name_en)>1'))->orderBy('name_en');

$grid->id('ID')->sortable();

$grid->name_cn('名称');

$grid->column('name_cn','名称');

$grid->column('type','类型？')->display(function ($type) {
 return $type == 1 ? '111' : '222';
});

$grid->model()->where('type', 0);

// 下面为三个时间字段的列显示
$grid->release_at();
$grid->created_at();
$grid->updated_at();

 //filter($callback)方法用来设置表格的简单搜索框
 $grid->filter(function ($filter) {
  //1.时间段筛选 设置created_at字段的范围查询
  $filter->between('created_at', '筛选时间')->datetime();
  //2.字段模糊查询 like = '% %'
  $filter->like('name', '姓名');
  //3.字段equal 筛选
  $filter->equal('status', '状态')->select([0 => '下线', 1 => '上线']);
  //4.去掉默认的ID搜索
  $filter->disableIdFilter();
  //5.
