在DB中创建模型和两个新表的关系

Question

我有两个表Post（id，text，id_tag）和Tag（id，name）。 如何为两个表创建关系，以及如何使用此表为工作框架创建模型。

Answer 1

你应该建立两个模型1）标签2）后，如：

1）标签

<?php 

namespace App\Models\frontend; 

use Illuminate\Database\Eloquent\SoftDeletes; 
use Illuminate\Database\Eloquent\Model; 

class Tag extends Model 
{ 
    use SoftDeletes; //<--- use the softdelete traits 

    protected $dates = ['deleted_at']; //<--- new field to be added in your table 

    /** 
    * The database table used by the model. 
    * 
    * @var string 
    */ 
    protected $table = 'tag'; 

    /** 
    * The database primary key value. 
    * 
    * @var string 
    */ 
    protected $guarded = ['id', '_token']; 

    /** 
    * Attributes that should be mass-assignable. 
    * 
    * @var array 
    */ 
    protected $fillable = ['name']; 



    /** 
    * That belong to the Tag. 
    */ 
    public function post() 
    { 
    return $this->hasMany('App\Models\Post'); 
    } 
} 

2）邮政

<?php 

namespace App\Models; 

use Illuminate\Database\Eloquent\SoftDeletes; 
use Illuminate\Database\Eloquent\Model; 

class Post extends Model 
{ 
    use SoftDeletes; //<--- use the softdelete traits 

    protected $dates = ['deleted_at']; //<--- new field to be added in your table 

    /** 
    * The database table used by the model. 
    * 
    * @var string 
    */ 
    protected $table = 'post'; 

    /** 
    * The database primary key value. 
    * 
    * @var string 
    */ 
    protected $guarded = ['id', '_token']; 

    /** 
    * Attributes that should be mass-assignable. 
    * 
    * @var array 
    */ 
    protected $fillable = ['text','id_tag']; 

    /** 
    * The roles that belong to the Post. 
    */ 
    public function tag() 
    { 
    return $this->belongsTo('App\Models\Tag','id_tag'); 
    } 
} 

希望这对你的工作！
