String of certain length in Sailsjs Model

问题

How can I enforce a Model property to be exactly 32 characters long?

I have tried

key : {
    type: 'string',
    len : 32
}

but it doesn't work.

Ok, let me tell you what i did.

After reading hours y figure out that "columnType" property is the solution. It works together with "type" property. For example. I have a "description" field. It looks like:

descripcion: { type: 'string', columnType: 'varchar (27)' }

And it works. (this is for mysql db).

I hope this works for you. This is on the docs. Model verbatim field

Apparently the correct way to do it is:

        maxLength   : 32,
        minLength   : 32,
