คนหลาย laravel
For example, a blog post may have an infinite number of comments. And a single
comment belongs to only a single post
class Post extends Model
{
public function comments()
{
return $this->hasMany('App\Models\Comment');
}
}
class Comment extends Model
{
public function post()
{
return $this->belongsTo('App\Models\Post');
}
}
laravel นเป็นของ
<?php
namespace App\Models;
use Illuminate\Database\Eloquent\Model;
class Phone extends Model
{
/**
* Get the user that owns the phone.
*/
public function user()
{
return $this->belongsTo('App\Models\User');
}
}
laravel หลายจะมีความสัมพันธ์
/*
users
id - integer
name - string
roles
id - integer
name - string
role_user
user_id - integer
role_id - integer
*/
class User extends Model
{
/**
* The roles that belong to the user.
*/
public function roles()
{
/*To determine the table name of the relationship's intermediate
table, Eloquent will join the two related model names in
alphabetical order. However, you are free to override this
convention. You may do so by passing a second argument to the
belongsToMany method*/
return $this->belongsToMany(Role::class,'role_user');
}
}
//Defining The Inverse Of The Relationship
class Role extends Model
{
/**
* The users that belong to the role.
*/
public function users()
{
return $this->belongsToMany(User::class);
}
}
laravel ความสัมพันธ์ต้องมีหลาย
// Post model
public function comments()
{
return $this->hasMany(Comment::class);
}
// Post controller
$comments = Post::find(1)->comments;

*/
public function comments()
{
return $this->hasMany('App\Models\Comment');
}
}
หลายที่มีความสัมพันธ์ laravel
use App\Models\User;
$user = User::find(1);
$user->roles()->attach($roleId);
