recursion - Accessing variable from parent object in go html template -


i have recursive go html templates showing replies post, top parent object contains field called random , field called replies, recurse on replies, don't have random field, want use same random field in each reply.

when try goes 2 replies deep (i assume because $ references parent object , not "top" parent object.

edit: more code. thread original object passed template, thread.replies looped on recursively, don't contain thread.random string. want make thread.random string available globally children without restructuring structs.

type thread struct {     random string     body string     title string     replies []*reply }  type reply struct {     body string     title string     replies []*reply }

template:

<html>                                                       <body>                                                     <div id="posts">     <p>.title</p>     <p>.body</p>                                             {{define "replies"}}                                       <ul>                                                         {{ range $key, $value := .replies }}                        <p>$value.title</p>                                        <p>$value.body</p>                                         <p>$.random</p>                                            {{template "replies" . }}                                  </li>                                                    {{end}}                                                  </ul>                                                      {{end}}                                                   <div id="posts">                                             <div class="replypost">{{ template "replies" .}}</div>   </div>                                                     </body>                                                  </html>

whatever want access in template must passed it. there no such thing "this struct field of other struct , want magically access other struct".
