覆盖模型的软删除表列(Overwriting soft delete table column for a model)

 我正在使用laravel 5.4。 
 
 我有一个指向具有以下属性的数据库表的模型。 
 
id       integer
name     varchar
location varchar
deleted  boolean
 
 这是一张旧表，由于它与一堆代码交织在一起，我们无法更改此表。 
 
 我想要做的是利用模型中的laravels软删除功能。 我知道laravel期望列名为deleted_at ，数据类型为数据库表上的date 。 
 
 我如何覆盖这个，以便Laravel查看deleted的列并检查它是否是一个boolean ？ 
 
 我已经尝试查看我的模型继承的类，但是无法找到定义处理它的常量和函数的位置。 我怀疑它可能在收藏品上，但没有运气。 
 
 理想情况下，我想简单地重新定义我的模型中的函数。 
 
 谢谢。 

I'm using laravel 5.4.
 
I have a model that points to a database table that has the following attributes.
 
id       integer
name     varchar
location varchar
deleted  boolean
 
This is an old table and due to it being entwined in a bunch of code we can't change this table.
 
What I want to do is take advantage of laravels soft delete functionality within a model. I know that laravel expects the column name to be deleted_at and the data type to be date on the database table.
 
How do I override this so this so that Laravel will look at the column deleted and check if it's a boolean?
 
I've tried looking at the classes that my model inherits from but haven't been able to find where the constant and function that handles this is defined. I suspect it might be on the collection but have had no luck.
 
Ideally I would like to simply redefine the functions in my model.
 
Thanks.
