Remove reationship from many-to-many models in laravel 4
提问by localhost
I tried the following:
我尝试了以下方法：
$one = OneModel::findOrFail($id);
$two = $one->two_model()->findOrFail($two_id);
$two->delete();
But that deletes the record from the database, how can I just remove the relationship without deleting from the table? And also not having to mess with the pivot table, because if that is needed, why am I even using a framework...
但这会从数据库中删除记录，我如何才能删除关系而不从表中删除？而且也不必弄乱数据透视表，因为如果需要，为什么我什至使用框架......

If I got you correctly, detach()is what you're looking for:
如果我猜对了，detach()就是你要找的：
$one = OneModel::findOrFail($id);
$one->two_model()->detach($two_id);
This will delete only the relation with one_model's table's $idand two_model's table's $two_idin your pivot table.
这将仅删除数据透视表中与one_model's table's$id和two_model's table's的关系$two_id。
