我想知道如何解决以下错误。
我的代码：
控制器/ application_controller.rb
class ApplicationController < ActionController::Base
def home
@app_name = Cache.app_name
respond_to do |format|
format.html {render "application/home"}
end
end
视图/应用/ home.html.erb
<h1>Home</h1>
错误：
Missing template application/home with {:locale=>[:en], :formats=>[:html], :handlers=>[:erb, :builder, :arb, :rabl]}.

提示：您不应将公开方法放入application_controller。有一个额外的控制器，并检查您的routes.rb和查看文件名称：
# in app/controllers/home_controller.rb
class HomeController < ApplicationController
def index
@app_name = Cache.app_name
end
end
# in app/views/home/index.html.erb
<h1>Home of <%= @app_name %></h1>
# in config/routes.rb
root to: 'home#index'

您可以使用rails生成器创建一个新的控制器来放置它。不要使用应用程序控制器。
例如： rails g controller home index
这将创建一个Home控制器和一个索引操作以及所需的默认文件。它还将为您创建路线和资产。
