在螺栓中找到一个

I have a Golang project and I am using Bolt as my Database. I found and started to use This project to handle the connection and operations over the database. My current problem is that I cannot make a search by one field and get one result.

My struct definition in Golang is:

type Component struct {
    ID          int      `storm:"increment"`
    Name        string   `storm:"id,unique"` // primary key
    Cars        []string `storm:"index"`  // this field will be indexed
    Houses      []string `storm:"index"`  // this field will be indexed
    Pets        []string `storm:"index"`  // this field will be indexed
    Children    []string `storm:"index"`  // this field will be indexed
    Level       int
}

At first, I know is strange to have one field ID and a field Name with the tag id, the thing is that I want the name as the id and possibly as the key. I made some inserts and everything is ok, I even retrieved all the values and it worked perfectly. Now, I want to get one element by his name, I have this:

name := "someComponent"
var component models.Component
err := db.One("Name", name, &component)

But it returns not found but I know that a component is stored with that name. In other hand, if I make the search with Find I get the element, but that command is to return many results, and I want only one, I have this:

var components []models.Component
err := db.Find("Name", name, &components)
