laravel8 eloquent relationships tutorial 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: associate laravel
When updating a belongsTo relationship, you may use the associate method. This
method will set the foreign key on the child model:
$account = App\Account::find(10);
$user->account()->associate($account);
$user->save();
When removing a belongsTo relationship, you may use the dissociate method. This
method will set the relationship foreign key to null:
$user->account()->dissociate();
$user->save();
