laravel 数据表编辑器出现 500 错误

Question

我有 yajra/laravel-datatables-editor 包中编辑器的设置数据table。我可以在数据 table 出现并工作的地方得到它，但是当我尝试编辑一个字段时它不会更新并且我在 ajax 调用中收到 500 错误消息 "Type error: Argument 1 passed to App\DataTables\DioceseDataTablesEditor::editRules() must be an instance of Illuminate\Database\Eloquent\Model, null given"

我遵循了随包提供的用户教程，只是使用不同的 table 和不同的行。寻找一些帮助，因为我对我所缺少的东西感到困惑。

这是我的 DioceseDataTablesEditor.php 文件，这是发生错误的地方。

namespace App\DataTables;

use App\Diocese;
use Illuminate\Validation\Rule;
use Yajra\DataTables\DataTablesEditor;
use Illuminate\Database\Eloquent\Model;

class DioceseDataTablesEditor extends DataTablesEditor
{
    protected $model = Diocese::class;

    /**
     * Get create action validation rules.
     *
     * @return array
     */
    public function createRules()
    {
        return [
            //'diocese' => 'required',
        ];
    }

    /**
     * Get edit action validation rules.
     *
     * @param Model $model
     * @return array
     */
    public function editRules(Model $model) //This is where the error occurs
    {
        return [
           // 'diocese'  => 'sometimes|required',
        ];
    }

    /**
     * Get remove action validation rules.
     *
     * @param Model $model
     * @return array
     */
    public function removeRules(Model $model)
    {
        return [];
    }

        /**
    * Pre-update action event hook.
    *
    * @param Model $model
    * @return array
    */
    public function updating(Model $model, array $data)
    {
        return $data;
    }
}

我注意到在 ajax 调用中，它从不发送行的唯一 ID，该行是我在 Diocese 模型中设置的名为 link 的列。这就是我认为可能是问题所在。它仅将以下内容发送到 post.

中的字段

动作：编辑数据[link][面额]:其他 //它是实际的单词 link 而不是带有整数的 link 值。

这是我的javascript。

$(function() {
                $.ajaxSetup({
                    headers: {
                        'X-CSRF-TOKEN': '{{csrf_token()}}'
                    }
                });

                var editor = new $.fn.dataTable.Editor({
                    ajax: "/admin/diocese",
                    table: "#diocese",
                    display: "bootstrap",
                    fields: [
                        { label: 'link', name: 'link' },
                        { label: 'denominat', name: 'denominat', type: 'select', options: [
                            "Catholic", "Episcopal", "Methodist", "PNCC", "American Baptist", "ELCA", "AMEZC", "Presbyterian", "Individual", "Other", "AME Church", "ACNA"
                        ] },
                        { label: 'abbrev', name: 'abbrev' },
                        { label: 'diocese', name: 'diocese' },
                        { label: 'addrone', name: 'addrone' },
                        { label: 'addrtwo', name: 'addrtwo' },
                        { label: 'city', name: 'city' },
                        { label: 'state', name: 'state' },
                        { label: 'zipcode', name: 'zipcode' },
                        { label: 'telephone', name: 'telephone' },
                    ]
                });

                $('#diocese').on('click', 'tbody td:not(:first-child)', function (e) {
                    editor.inline(this);
                });

                {{$dataTable->generateScripts()}}
            })

如有任何帮助，我们将不胜感激。

编辑。这是控制器

namespace App\Http\Controllers;

use Illuminate\Http\Request;
use App\DataTables\DioceseDataTable;
use App\DataTables\DioceseDataTablesEditor;
use Illuminate\Support\Facades\Schema;

class DioceseController extends Controller
{
    public function index(DioceseDataTable $dataTable)
    {
        return $dataTable->render('admin.diocese.index');
    }

    public function store(DioceseDataTablesEditor $editor)
    {
        return $editor->process(request());

    }

    public function getTableColumns($table)
    {
        return Schema::getColumnListing($table);
    }

}

Answer 1

我已经解决了这个问题，我会留下答案以备将来参考。认为作为 data[link][denominat] = "Others" 发送的数据是错误的，我设置了一个简单的测试表单，将数据作为 ajax post 发送，但是它看起来像我认为它应该看起来像 data[42456][denominat] = "Others" 当我这样做时它工作得很好。

然后我查看了更多编辑器文档，我不得不让编辑器知道我的主键名称 "link" 所以代码更改为下面的内容。

var editor = new $.fn.dataTable.Editor({
                    ajax: "/admin/diocese",
                    table: "#diocese",
                    idSrc: "link",  // ##added this line 
                    display: "bootstrap",
                    fields: [
                        { label: 'link', name: 'link' },
                        { label: 'denominat', name: 'denominat', type: 'select', options: [
                            "Catholic", "Episcopal", "Methodist", "PNCC", "American Baptist", "ELCA", "AMEZC", "Presbyterian", "Individual", "Other", "AME Church", "ACNA"
                        ] },
                        { label: 'abbrev', name: 'abbrev' },
                        { label: 'diocese', name: 'diocese' },
                        { label: 'addrone', name: 'addrone' },
                        { label: 'addrtwo', name: 'addrtwo' },
                        { label: 'city', name: 'city' },
                        { label: 'state', name: 'state' },
                        { label: 'zipcode', name: 'zipcode' },
                        { label: 'telephone', name: 'telephone' },
                    ]
                });
