Question

我是ROR的新手。我正在开发一个使用erb文件的项目，现在我已将它们转换为haml。

我已经在其他帖子中提到了 haml gem ，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。请帮忙 如果需要其他任何信息，请告诉我 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

这是页面控制器扩展应用程序控制器，但它不呈现应用程序布局

class PagesController < ApplicationController
  def home 

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

服务器日志您可以在此处注意，虽然所有文件都是haml但是渲染 pages / home.html.erb 不知道从何处！

Answer 1

实际上你不需要布局，只需要简单的部分。

= render 'layouts/header'

使用此类构造时，您尝试渲染部分内部布局。

确保其名称为＆＃39; app / views / layouts / _header.html.haml＆＃39;

按惯例，partials应从下划线字符开始。

Application.html.haml文件未呈现
