many to many in laravel code example
Example 1: one to many 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');
}
}
Example 2: laravel detach
$user->roles()->detach($roleId);
$user->roles()->detach();

<?php
namespace App\Models;
use Illuminate\Database\Eloquent\Model;
class Post extends Model
{
public function comments()
{
return $this->hasMany('App\Models\Comment');
