Application.html.haml文件未呈現

Question

我是ROR的新手。我正在使用erb文件的項目，現在我已經將它們轉換爲haml。

我已經安裝了哈姆寶石正如其他帖子中提到的，但沒有運氣！ 並使用導軌4.

問題是這個application.haml文件沒有呈現我不知道爲什麼。 請幫助 請讓我知道如果任何其他信息需要 這裏是application.html.haml

!!! 
%html 
    %head 
    %title PipeCast 
    %link{:rel => "stylesheet", :href => "assets/stylesheets/application.css"} 
    = csrf_meta_tags 
    = render 'layouts/shim' 
    %body 
    = render 'layouts/header' 
    = yield 

這裏是application_controller.rb

class ApplicationController < ActionController::Base 

    # Prevent CSRF attacks by raising an exception. 
    # For APIs, you may want to use :null_session instead. 
    # protect_from_forgery with: :null_session 

    # before_filter :set_cache_buster 
# 
    # def set_cache_buster 
    # response.headers["Cache-Control"] = "no-cache, no-store, max-age=0, must-revalidate" 
    # response.headers["Pragma"] = "no-cache" 
    # response.headers["Expires"] = "Fri, 01 Jan 1990 00:00:00 GMT" 
    # end 
# 
end 

這頁控制器擴展應用程序控制器，但其沒有渲染應用程序佈局

個

class PagesController < ApplicationController 
    def home 

    @greeting = "Hello Welcome to Ruby Web Application" 
    end 
end 

Server日誌你可以儘管所有文件都是HAML這裏需要注意的卻是呈現頁/ home.html.erb不知道從那裏！

Answer 1

其實你不需要佈局，只是簡單的部分。

= render 'layouts/header' 

當你使用這樣的構造時，你試圖呈現部分內部佈局。

確保，它的名字是「應用程序/視圖/佈局/ _header.html.haml」

通過約定的諧音應該從下劃線開始。
