Php 具有字段关系的Laravel背包列表值

我试图列出一个表中的值，该表包含在模型中建立的关系，但显示的是id，而不是与该id相关的名称：

District.php和迁移：

<?php

    namespace App\Models;
    
    use Illuminate\Database\Eloquent\Model;
    use Backpack\CRUD\CrudTrait;
    
    class District extends Model
    {
        use CrudTrait;
    
         /*
        |--------------------------------------------------------------------------
        | GLOBAL VARIABLES
        |--------------------------------------------------------------------------
        */
    
        protected $table = 'districts';
        protected $primaryKey = 'id';
        // public $timestamps = false;
        // protected $guarded = ['id'];
        protected $fillable = ['name'];
        // protected $hidden = [];
        // protected $dates = [];
    
        /*
        |--------------------------------------------------------------------------
        | FUNCTIONS
        |--------------------------------------------------------------------------
        */
    
        /*
        |--------------------------------------------------------------------------
        | RELATIONS
        |--------------------------------------------------------------------------
        */
        public function county()
        {
            return $this->hasMany('App\Models\County');
        }

<?php   
    use Illuminate\Database\Schema\Blueprint;
    use Illuminate\Database\Migrations\Migration;
    
    class CreateDistrictsTable extends Migration
    {
        /**
         * Run the migrations.
         *
         * @return void
         */
        public function up()
        {
            Schema::create('districts', function (Blueprint $table) {
                $table->increments('id');
                $table->string('name')->unique();
                $table->timestamps();
            });
        }
    
        /**
         * Reverse the migrations.
         *
         * @return void
         */
        public function down()
        {
            Schema::drop('districts');
        }
    }`

<?php
    
    use Illuminate\Database\Schema\Blueprint;
    use Illuminate\Database\Migrations\Migration;
    
    class CreateDistrictsTable extends Migration
    {
        /**
         * Run the migrations.
         *
         * @return void
         */
        public function up()
        {
            Schema::create('districts', function (Blueprint $table) {
                $table->increments('id');
                $table->string('name')->unique();
                $table->timestamps();
            });
        }
    
        /**
         * Reverse the migrations.
         *
         * @return void
         */
        public function down()
        {
            Schema::drop('districts');
        }
    }

您需要做的是更改此代码：

$this->crud->addColumn([
        'label' => "District", // Table column heading
        'type' => "text",
        'name' => 'DistrictID', // the column that contains the ID of that connected entity;
        'entity' => 'district', // the method that defines the relationship in your Model
        'attribute' => "name", // foreign key attribute that is shown to user
        'model' => 'App\Models\District' // foreign key model
    ]);

$this->crud->setColumnDetails('DistrictID', ['attribute' => 'name']);

致：

注意：将
$this->crud->addColumn
和
$this->crud->setColumnDetails
更改为仅
$this->crud->setColumnDetails
