遍历结构并执行数据库查询

So I'm new to go and I come from a javascript/node background and for practice, I've been rewriting some of my javascript code into go.

I have a situation where I have an struct (in node it was my object) and I need to iterate over it and perform two database queries. I have something that works but it seems costly and repetitive.

Struct:

type SiteUsers struct {
    Active struct {
        Moderators []string `json:"moderators"`
        Admins     []string `json:"admins"`
        Regulars   []string `json:"regulars"`
    } `json:"active"`
}

Then in the function where I handle an api request that returns JSON binded to this struct I use a for range loop for each role under active. For each one I perform the same first query and then a second one that is specific to each one.

v := getSiteUsers(&usrs, website)

for _, moderators := range v.Active.Moderators {
    // Insert into user table
    // Insert into user table with role of moderator
}

for _, admins := range v.Active.Admins {
    // Insert into user table
    // Insert into user table with role of admin
}

for _, regulars := range v.Active.Regulars {
    // Insert into user table
    // Insert into user table with role of regular
}

This method will work but it doesn't feel completely right and I would love to get some input from people experienced with go.

Would something like this be better?

v := getSiteUsers(&usrs, website)

insertUsers := func(users []string, role roleType) {
    for _, user := range users {
        // Insert into user table
        // Insert into user table with given role
    }
}

insertUsers(v.Active.Moderators, moderatorRole)
insertUsers(v.Active.Admins, adminRole)
insertUsers(v.Active.Regulars, regularRole)
