Question

我有2个雄辩的模特：

/**
* Entities/Products.php
*/
use CrudTrait;

protected $fillable = [
    'name', 'macronutrients_id',
];

public function macronutrients()
{
    return $this->hasOne(Macronutrients::class);
}


/**
* Entities/Macronutrients.php
*/
use CrudTrait;

protected $fillable = [
    'proteins', 'fats', 'carbons', 'calories', 'product_id'
];

public function product()
{
    return $this->belongsTo(Product::class);
}

我不知道如何通过Laravel Backpack CRUD在产品的编辑页面上显示带有所有常量营养素的表格（或选项列表之类的东西）？

换句话说，我想做这样的事情：

第http://example.com/admin/product/2/edit页：

* [text] Name

* Macronutrients:
[number] proteins
[number] fats
[number] carbons
[number] calories

其中[文本]，[数字]是输入字段。

Answer 1

$this->crud->addColumn([
    // 1-n relationship
    'label' => "Country name", // Table column heading
    'type' => "select",
    'name' => 'country_name', // the column that contains the ID of that connected entity;
    'entity' => 'country', // the method that defines the relationship in your Model
    'attribute' => "country_name", // foreign key attribute that is shown to user
    'model' => "App\Models\Country",
]);

这是laravel背包中1-n关系的一个例子

Laravel背包。 1-1（一对一）关系
