Application.html.haml文件未呈现

Question

我是ROR的新手。我正在使用erb文件的项目，现在我已经将它们转换为haml。

我已经安装了哈姆宝石正如其他帖子中提到的，但没有运气！ 并使用导轨4.

问题是这个application.haml文件没有呈现我不知道为什么。 请帮助 请让我知道如果任何其他信息需要 这里是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 

这里是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 

这页控制器扩展应用程序控制器，但其没有渲染应用程序布局

个

class PagesController < ApplicationController 
    def home 

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

Server日志你可以尽管所有文件都是HAML这里需要注意的却是呈现页/ home.html.erb不知道从那里！

Answer 1

其实你不需要布局，只是简单的部分。

= render 'layouts/header' 

当你使用这样的构造时，你试图呈现部分内部布局。

确保，它的名字是“应用程序/视图/布局/ _header.html.haml”

通过约定的谐音应该从下划线开始。
