Golang，模板未定义

I'm currently trying to create a small web application using golang and I'm following the tutorial on their webpage (https://golang.org/doc/articles/wiki/final.go). Instead of having the templates on the same folder as the rest of the code I'm trying to move them into templates/template_name.html.

For template rendering I'm using the following code:

var templates = template.Must(template.ParseFiles("templates/edit.html", "templates/view.html"))

func renderTemplate(w http.ResponseWriter, tmpl string, p *Page) {
    err := templates.ExecuteTemplate(w, "templates/"+tmpl+".html", p)
    if err != nil {
            http.Error(w, err.Error(), http.StatusInternalServerError)
    }
}

And for example my View handler is the following:

func viewHandler(w http.ResponseWriter, r *http.Request, title string) {                                                                                                                                    
    p, err := loadPage(title)                                                                                                                                                                           
    if err != nil {                                                                                                                                                                                     
            http.Redirect(w, r, "/edit/"+title, http.StatusFound)                                                                                                                                       
            return                                                                                                                                                                                      
    }                                                                                                                                                                                                   
    renderTemplate(w, "view", p)                                                                                                                                                                        

}

I have the templates/ folder with the edit.html and view.html file inside. I run the full code with: go run wiki.go but when I try to access the webpage I get the following error:

html/template: "templates/view.html" is undefined

Any idea of what might be happening?
