How to range over slice of structs instead of struct of slices

go, go-templates, html, struct, templates

Solution

Use:

{{range .}}
    {{.Id}}
    {{.Name}}
{{end}}

for the template. Here is a example: http://play.golang.org/p/A4BPJOcfpB You need to read more about the "dot" in the package overview to see how to properly use this. http://golang.org/pkg/text/template/#pkg-overview (checkout the Pipelines part)

Problem

Having played around with Go HTML templates a bit, all the examples I found for looping over objects in templates were passing structs of slices to the template, somewhat like in this example : ``` type UserList struct { Id []int Name []string } var templates = template.Must(template.ParseFiles("main.html")) func rootHandler(w http.ResponseWriter, r *http.Request) { users := UserList{ Id: []int{0, 1, 2, 3, 4, 5, 6, 7}, Name: []string{"user0", "user1", "user2", "user3", "user4"}, } templates.ExecuteTemplate(w, "main", &users) } ``` with the "main" template being : ``` {{define "main"}} {{range .Name}} {{.}} {{end}} {{end}} ``` This works, but i don't understand how I'm supposed to display each ID just next to its corresponding Name if i'm ranging on the .Name property only. I would find it more logical to treat each user as an object to group its properties when displaying. Thus my question: What if I wanted to pass a slice of structs to the template? What would be the syntax to make this work? I haven't found or understood how to in the official html/template doc. I imagined something looking remotely like this: ``` type User struct { Id int Name string } type UserList []User var myuserlist UserList = ... ``` and a template looking somewhat like this: (syntax here is deliberately wrong, it's just to get understood) ``` {{define "main"}} {{for each User from myuserlist as myuser}} {{myuser.Id}} {{myuser.Name}} {{end}} {{end}} ```
