mysql - 如何将数据表列名称和值重命名为从 infyom laravel 生成器生成的岛名称？

Question

我有 Island 和 Fisher 的两个模型。我想使用数据表来显示岛屿名称而不是 (island_id) fisher_first_name 和 fisher_last_name

如数据表所示

岛屿 ID Fisher 名字 Fisher 姓氏

1 Dovecot Imap 2 乔恩·蒂姆

这是我的两个模型关系

public function fishers(){
        return $this->hasMany(Fisher::Class);
   }

  public function island(){
        return $this->belongsTo(Island::Class,'island_id');
    }

这是 FisherDatatable 中的 getColumns 函数，我需要使用它来将 island_id 更改为 island_names

 protected function getColumns()
    {
        return [

          'island_id'
            'fisher_first_name',
            'fisher_last_name',

        ];
    }

这也是从 FisherDatatable 中提取的，用于显示 Island 和 Fisher 关系

  public function query(Fisher $model)
    {
        return $model->newQuery()->with(['island']);
    }

这是我的控制器

use App\DataTables\FisherDataTable;
use App\Http\Requests;
use App\Http\Requests\CreateFisherRequest;
use App\Http\Requests\UpdateFisherRequest;

        $this->fisherRepository = $fisherRepo;
    }

    /**
     * Display a listing of the Fisher.
     *
     * @param FisherDataTable $fisherDataTable
     * @return Response
     */
    public function index(FisherDataTable $fisherDataTable)
    {
        return $fisherDataTable->render('fishers.index');
    }

    /**

     *
     * @return Response
     */
    public function create()
    {
        $islands = Island::pluck('island_name','id');
        return view('fishers.create')->with('islands',$islands);

        return redirect(route('fishers.index'));

            return redirect(route('fishers.index'));

    {
        $fisher = $this->fisherRepository->find($id);
        $islands = Island::pluck('island_name','id');
        if (empty($fisher)) {
            Flash::error('Fisher not found');

            return redirect(route('fishers.index'));
        }

        return view('fishers.edit')
        ->with('fisher', $fisher)
       -> with('islands', $islands);
    }

    /**

    public function update($id, UpdateFisherRequest $request)
    {
        $fisher = $this->fisherRepository->find($id);

        if (empty($fisher)) {
            Flash::error('Fisher not found');

            return redirect(route('fishers.index'));
        }

        $fisher = $this->fisherRepository->update($request->all(), $id);

        Flash::success('Fisher updated successfully.');

        return redirect(route('fishers.index'));
    }

    /**
     * Remove the specified Fisher from storage.
     *
     * @param  int $id
     *
     * @return Response
     */
    public function destroy($id)
    {
        $fisher = $this->fisherRepository->find($id);

        if (empty($fisher)) {
            Flash::error('Fisher not found');

           return redirect(route('fishers.index'));
        }

        $this->fisherRepository->delete($id);

        Flash::success('Fisher deleted successfully.');

        return redirect(route('fishers.index'));
    }
}

只需将名称、标题和数据数组添加到您的 getColumns 方法中

protected function getColumns()
    {
   return [
            ['name'=>'dropdown_label','title'=>'new name of label','data'=>"dropdown_label"],
            ['name'=>'dropdown_value','title'=>'new name of dropdwon value','data'=>"dropdown_value"],
            'active'
          ];
            
    }
