我刚在Rails 3.1.1中创建了一个新的rails应用程序,我的应用程序布局没有在浏览器中呈现。唯一呈现的是我放在视图中的代码(例如views / public / home.html.erb)。
它只渲染通过<%= yield%>传输的内容。例如,localhost:3000 / public / home仅显示以下内容:
<h1>Homepage</h1>
<h2>Here we go.</h2>
<a href="/#">Visit the login page</a>
这是我的/layouts/application.html.erb中的内容:
<!DOCTYPE html>
<html>
<head>
<title>My App</title>
<%= stylesheet_link_tag "application" %>
<%= javascript_include_tag "application" %>
<%= csrf_meta_tags %>
</head>
<body>
<ul class="user_nav">
<% if current_user %>
<li>
Logged in as <%= current_user.email %>.
</li>
<li>
<%= link_to "Log out", logout_path %>
</li>
<% else %>
<li>
<%= link_to "Sign up", signup_path %>
</li>
<li>
<%= link_to "Log in", login_path %>
</li>
<% end %>
</ul>
<% flash.each do |name, msg| %>
<%= content_tag :div, msg, :id => "flash#{name}" %>
<% end %>
<%= yield %>
<h1>test!</h1>
</body>
</html>
以下是我的路线:
root :to => "public#home"
match "/secret" => "public#secret"
get "logout" => "sessions#destroy", :as => "logout"
get "login" => "sessions#new", :as => "login"
get "signup" => "users#new", :as => "signup"
resources :users
resources :sessions
这是application_contoller.rb中的内容:
class ApplicationController < ActionController::Base
protect_from_forgery
end
这是public_controller.rb中的内容:
class PublicController < ActionController::Base
protect_from_forgery
def home
end
def secret
end
end
这是sessions_contoller.rb中的内容:
class SessionsController < ApplicationController
def new
end
def create
user = login(params[:email], params[:password], params[:remember_me])
if user
redirect_back_or_to root_path, :notice => "Logged in!"
else
flash.now.alert = "Email or password was invalid"
render :new
end
end
def destroy
logout
redirect_to root_path, :notice => "Logged out"
end
end
以下是users_controller.rb中的内容:
class UsersController < ApplicationController
def new
@user = User.new
end
def create
@user = User.new(params[:user])
if @user.save
redirect_to root_path, :notice => "Signed up!"
else
render :new
end
end
end

我自己也遇到了同样的问题,问题只是一个简单的错误。
你的控制器PublicController是子类“ActionController :: Base”。 ApplicationController以外的控制器需要从ApplicationController继承,以便在application.html.erb布局中呈现它们的视图
如果你改变了
PublicController < ActionController::Base
到
PublicController < ApplicationController
它应该有用。

最后一个皱纹陷入同样的问题:我在子类控制器中重写初始化。确保首先调用'超级':
def initialize
super
@some_client = SomeClient.new
end
