如何使用两组数据修复golang嵌套模板

Question

I want to get two data structs into a golang nested template, I've created a struct like this for 'url' and for 'user' data like so,

type url struct {
    id    string
    Userid    string
    Long_url  string
    Short_url string
}
type user struct {
    Email        string
    First_name   string
    Last_name    string
    Password     []byte
}

I want to get the two sets of data into a nested golang template. The user data is just one set of data and the url struct will have many rows of data.

My idea is that I would create another struct like so,

   type Data struct {
        UU []url
        User []user
    }

and then do the following,

  bb := []url{urls}
  tu := []user{u}
  data := &Data{bb, tu}
 tp.ExecuteTemplate(w, "form", data)

the output of the url data is like this,

[{2 123 https://confluence.expedia.biz/display/INFRAENG/Graphite+Infrastructure short2} {1 123 https://tour.golang.org/moretypes/13 short}]

the error I get is as follows:

error:  "cannot use urls (type []url) as type url in array or slice literal"

I'm really not sure how to progress, can you help?

Always create a test case on playground to test your problem and to share with others. Hope this helps.

type Data struct {
    url  // embedded
    User []user
}
