/////////////////////////
// We can see that the Pivot class is extends Model class,
// it just use the AsPivot trait, set the $incrementing = false,
// and set the $guarded = [].

// So, we can run the methods of Model in Pivot entity, such as @delete.
// Working:
$user = User::find(1);
$client = $user->clients->firstWhere('id', $clientId);
if ($client) {
    $client->pivot->delete();
}

// Last:
// You may have seen that I added a 'is_enabled' field in the pivot table,
// I think it may better than SoftDeletes.

是的，你可以在数据透视表上进行软删除，你所需要的只是给它们自己的id和时间戳。这样“SoftDeletingTrait”就可以工作了。这有点棘手，但对我来说很有效。编辑：
我还忘了提到，您必须为数据透视表创建一个模型，就像上面有人告诉您的那样=P。例如，您有一个信用额度，以及该信用额度的多个请求，这些请求用于多个credit_lines，但您希望了解每一行上请求的状态，以及从该信用额度中删除的请求，而不是从其他信用额度中删除的请求。

Table
credit_line
id
name
capital
[More columns]
Table
requirements (Documents and things that everybody uses)
id
name
[More columns]

Table (pivot)

credit_line_has_requirements
id <---- you need this...
timestamps <---- also this
status_id <---- declined, accepted etc... 
reason <---- a text description of why you declined or acepted the requeriment...

然后使用数据透视表为CreditLineHasRequeriments创建一个模型。
抱歉我的英语不好。

如果您需要在数据透视表中使用softDeletes特征，则必须扩展数据透视模型vai Laravel的常规模型，而不是数据透视模型，即

YourPivotModal extends Illuminate\Database\Eloquent\Model; instead of 

YourPivotModal extends Illuminate\Database\Eloquent\Relations\Pivot;

此外，必须在透视表中定义deleted_at列
