在 Laravel 刀片视图中使用变形关系创建锚标签

Question

我有一个应用程序，其中发票可以属于客户或供应商。现在我在当前场景中使用了变形的东西。我想通过使用 morph 关系创建正确的锚但是我没有找到 Laravel 的最佳方法

Client.php

class Client extends Model
{
    /**
     * Get the client's invoices.
     */
    public function invoices()
    {
        return $this->morphMany('App\Invoice', 'contact');
    }
}

Supplier.php

class Supplier extends Model
{
    /**
     * Get the supplier's invoices.
     */
    public function invoices()
    {
        return $this->morphMany('App\Invoice', 'contact');
    }
}

Invoice.php

class Invoice extends Model
{
    /**
     * Get the owning contact model.
     */
    public function contact()
    {
        return $this->morphTo();
    }
}

现在在某处（发票详细信息页面），我想将锚点添加到发票的联系人（供应商或客户）但我需要知道是否有任何 Laravel 的方式。

如果发票的联系人属于 App\Client，则 href 将为“/clients/contact_id”，如果属于 App\Supplier，则其应为“/supplier/contact_id”

invoices/show.blade.php

<a href=""><b>{{ $invoice->contact->name }}</b></a>

Answer 1

您可以尝试为您的问题提供解决方案。

<?php

//You can see here for all table migration files

// For Client Table
Schema::create('client', function (Blueprint $table) {
    $table->increments('id');
    $table->string("client_name");
    $table->timestamps();
    // You can add your more fields and you can change field name also
});


// For Supplier Table
Schema::create('supplier', function (Blueprint $table) {
    $table->increments('id');
    $table->string("supplier_name");
    $table->timestamps();
    // You can add your more fields and you can change field name also
});

// For Invoice Table
Schema::create('invoices', function (Blueprint $table) {

    $table->increments('id');
    $table->morphs('invoice');
    $table->timestamps();
    // You can add your more fields and you can change field name also
});

//Note:
$table→morphs('invoice') would automatically create two columns using the text passed to it + “able”. So it will result in invoiceable_id and invoiceable_type.
?>

这里是 morphTo relationship 的模型

客户端模型： Client.php

<?php
 
namespace App;
use Illuminate\Database\Eloquent\Model;
 
class Client extends Model
{
    /**
     * Get all of the Client's invoices.
     */
    public function invoices()
    {
        return $this->morphMany(Invoices::class, 'invoiceable');
    }
}
?>

供应商模型： Supplier.php

<?php
 
namespace App;
 
use Illuminate\Database\Eloquent\Model;
 
class Supplier extends Model
{
     /**
     * Get all of the Supplier's invoices.
     */
    public function invoices()
    {
        return $this->morphMany(Invoices::class, 'invoiceable');
    }
}
?>

发票模型： Invoices.php

<?php
 
namespace App;
 
use Illuminate\Database\Eloquent\Model;
 
class Invoices extends Model
{
    /**
     * Get all of the owning invoiceable models.
     */
    public function invoiceable()
    {
        return $this->morphTo();
    }
}
?>

现在您可以使用多态关系使用客户和供应商检索记录。

使用客户端模型检索记录。

$client = Client::find(1);  
dd($client->invoices);

使用供应商模型检索记录。

$supplier = Supplier::find(1);   
dd($supplier->invoices);

您也可以检索记录

$client = Client::find(1);  
foreach ($client->invoices as $invoice) {
     <a href="{{ route('view-client', ['id' => $invoice->id]) }}">
         <b>{{ $invoice->client_name }}</b>
     </a>
}
