laravel pivot table relationships 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();
Example 3: laravel pivot table model
public function customer(){
return $this->belongsToMany('customer')->withPivot(
'start_date',
'stop_date',
'rem_date',
'due_date',
'status'
);
}
public function services(){
return $this->belongsToMany('Service')->withPivot(
'start_date',
'stop_date',

'due_date',
'status'
);
}
public function staff(){
return $this->belongsToMany('Staff');
