问题 Here is a sample database-table ( users ): id - int(11) auto_increment name - varchar(100) banned - int(1) The column banned is a boolean value which is 0 ( false ) by default.

问题 When updating a model and I sync a relationship, if I don't pass in all the ids that already exist, will that relationship be removed? 回答1: You decide: sync has 2nd parameter that defaults to true and is responsible for detaching: $model->relationship()->sync([1,2,3]); $model->relationship()->sync([4,5,6]); // attached [4,5,6], detached [1,2,3] $model->relationship()->getRelatedIds(); // [4,5,6] // but: $model->relationship()->sync([4,5,6], false); // attached [4,5,6], detached [] $model-
