laravel ORM合并两个json数组

Question

请问，我用 laravel ORM 有两个 json 数组，像这样：

php

$personnels = Personnel::all();
$skills = Languagelv::all();
return view('bs_sidebar/recommend',[
            'personnels' => $personnels,
            'skills' => $skills,
]);

型号

class Personnel extends Model
{
    protected $table = 'personnels';

    protected $fillable = ['name', 'sex'];
}

class Personnels_skill extends Model
{
    public $timestamps = false;
    protected $table = 'personnels_skill';
    protected $fillable = ['skill_name','personnels_id'];
}

json 结果

{personnels:[
    {"id" : 1,"name"  : "bruce","sex"   : 1},
    {"id" : 2,"name" : "peter","sex"  : 0}
    ]
};
{skill:[
        {"id" : 1,"skill_name": 'php', "personnels_id" : 1},
        {"id" : 2,"skill_name": 'jsp',"personnels_id" : 1},
        {"id" : 3,"skill_name": 'asp',"personnels_id" : 2}
       ]
};

我想合并两个json数组

（人员 id = 技能人员_id）

技能数组进入人员数组

喜欢这个结果：

{merge:[
        {"id":1,"name":"bruce","sex:1,"skill":[{"id": 1,"skill_name": 'php', "personnels_id" : 1},{"id": 2,"skill_name": 'jsp',"personnels_id" : 1}]},

        {"id":2,"name":"peter","sex":0,"skill":[{"id": 3,"skill_name": 'asp',"personnels_id" : 2}
        ]
};

我该怎么办，请帮帮我，谢谢。

Answer 1

如果您在模型中正确配置了关系，您应该能够执行以下操作：

$personnel = Personnel::with('skills')->get();
return view('bs_sidebar/recommend', compact('personnel'));

编辑 给定您的模型，如果您添加以下关系，您将能够使用上面的 Eloquent 查询。

class Personnel extends Model
{
    protected $table = 'personnels';

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

    public function skills() 
    {
        return $this->hasMany(Personnels_skill::class, 'personnel_id', 'id');
    }
}

class Personnels_skill extends Model
{
    protected $table = 'personnels_skill';

    protected $fillable = [
        'personnel_id',
        'skill_name',
    ];

    public $timestamps = false; 

    public function personnel()
    {
        return $this->belongsTo(Personnel::class, 'id', 'personnel_id');
    }
}

让我们试试这个 它会起作用的。

      foreach ($personnels as $key => $value) {
        $skill_list = DB::table('skill')->where('personnels_id','=',$value->id)->get();
        $personnels[$key]->skill = $skill_list;   
                    }  

return view('bs_sidebar/recommend',['personnels' => $personnels]);
