在练习基于 Go 语言构建在线论坛（五）：创建群组和主题功能实现的时候遇到了一些问题。

访问群组页面的时候，并没有出现回复框。其中views下的文件都是一致的。

这是handlers/thread.go

xxxxxxxxxx
 
func ReadThread(writer http.ResponseWriter, request *http.Request) {
    vals := request.URL.Query()
    uuid := vals.Get("id")
    thread, err := models.ThreadByUUID(uuid)
    if err != nil {
        fmt.Println("Cannot read thread",err)
    } else {
        _, err := session(writer, request)
        if err != nil {
            generateHTML(writer, &thread, "layout", "navbar", "thread")
        } else {
            generateHTML(writer, &thread, "layout", "auth.navbar", "auth.thread")
        }
    }
}

这是创建群组页面的handlers\thread\NewThread.go

xxxxxxxxxx
 
func NewThread(writer http.ResponseWriter, request *http.Request) {
    _, err := session(writer, request)
    if err != nil {
        http.Redirect(writer, request, "/login", 302)
    } else {
        generateHTML(writer, nil, "layout", "auth.navbar", "new.thread")
    }
}

这是new.thread.html

xxxxxxxxxx
 
{{ define "content" }}
​
    <form role="form" action="/thread/create" method="post">
        <div class="lead">Start a new thread with the following topic</div>
        <div class="form-group">
            <textarea class="form-control" name="topic" id="topic" placeholder="Thread topic here" rows="4"></textarea>
            <br/>
            <br/>
            <button class="btn btn-lg btn-primary pull-right" type="submit">Start this thread</button>
        </div>
    </form>
​
{{ end }}

经过多次排查，还是找不到问题..
