Question

我的控制器是这样的：

public function create()
{ 
    $data = array(
                'email' => 'chelsea@gmail.com'
            );

    $data = Order::where('email', $data['email'])->first();
    dd($data);
}

我的模型订单是这样的：

<?php

namespace App\Models;

use Eloquent as Model;
use Illuminate\Database\Eloquent\SoftDeletes;
use Illuminate\Notifications\Notifiable;

class Order extends Model
{
    use SoftDeletes, Notifiable;

    public $table = 'orders';

    protected $dates = ['deleted_at'];

    public $fillable = [
        'number',
        'user_id',
        'store_id',
        'total_amount',
        'total_product',
        'service_amount',
        'status',
        'checkout_at'
    ];

    protected $casts = [
        'number' => 'string',
        'user_id' => 'integer',
        'store_id' => 'integer',
        'total_amount' => 'integer',
        'total_product' => 'integer',
        'service_amount' => 'integer',
        'status' => 'integer',
        'checkout_at' => 'date'
    ];

    public static $rules = [
        'user_id' => 'required',
        'store_id' => 'required'
    ];

    public function user()
    {
        return $this->belongsTo(User::class,'user_id','id');
    }

    public function store()
    {
        return $this->belongsTo(Store::class,'store_id','id');
    }
}

表用户有字段ID，姓名，电子邮件等

表商店有字段ID，姓名，电子邮件等

我想从表用户和表存储中获取用户名和存储名称。然后，我想将它存储在变量$data

上

我该怎么做？

我的模特用户是这样的：

<?php

namespace App\Models;
use Eloquent as Model;
use Illuminate\Database\Eloquent\SoftDeletes;

class User extends Model
{
    use SoftDeletes;
    public $table = 'users';
    protected $dates = ['deleted_at'];

    public $fillable = [
        'name',
        'email',
        'password',
        'full_name',
        'birth_date',,
        'mobile_number',
    ];

    protected $casts = [
        'name' => 'string',
        'email' => 'string',
        'password' => 'string',
        'full_name' => 'string',
        'birth_date' => 'date',,
        'mobile_number' => 'string',
    ];

    public static $rules = [
        'name' => 'required',
        'email' => 'required'
    ];
}

我的模型商店是这样的：

<?php

namespace App\Models;
use Eloquent as Model;
use Illuminate\Database\Eloquent\SoftDeletes;

class Store extends Model
{
    use SoftDeletes;
    public $table = 'stores';
    protected $dates = ['deleted_at'];

    public $fillable = [
        'user_id',
        'domain',
        'name',
        'email'
    ];

    protected $casts = [
        'user_id' => 'integer',
        'domain' => 'string',
        'name' => 'string',
        'email' => 'string'
    ];

    public static $rules = [
        'user_id' => 'required',
        'domain' => 'required',
        'name' => 'required'
    ];

    public function user()
    {
        return $this->belongsTo(User::class,'user_id','id');
    }
}

Answer 1

首先，您需要为User Table和Store表创建模型，然后在两个模型中定义相应的表名......

public function create(Request $request)
{ 
    $data  = $request->all();
    $email = 'chelsea@gmail.com';
    $user  = User::where('email', $email)->first();
    $store = Store::where('email', $user->email)->first();
    $order = Order::where('user_id', $user->id)->where('store_id', $store->id)->first();


    $result = array();
    $result['orderTable'] = $order;
    return $result;


}

Answer 2

在订单控制器查询中使用with，只需传递您在订单模型查询中声明的关系数组，将根据模型关系获取相关表数据，如下所示

按顺序控制器

$data = Order::where('col', 'val')->with(['user','store'])->first();

订购模式

public function user()
{
    return $this->belongsTo(User::class,'user_id','id');
}

public function store()
{
    return $this->belongsTo(Store::class,'store_id','id');
}

如何在laravel 5.3上使用雄辩的关系？
