我在我的网站上使用rails_admin gem。 安装后，去localhost：3000 / admin，任何人都可以访问管理页面，我想停止它。
我使用的教程：http://amrithaprasad.com/2012/09/19/getting-started-with-rails_admin.html
首先，如果可能的话，我不想使用任何宝石，浏览后我在文件config / initializers / rails_admin.rb中找到了这个解决方案
RailsAdmin.config do |config|
ADMIN_EMAILS= ['youremail@email.com', 'email2@email.com']
config.current_user_method { current_user } # auto-generated
config.authenticate_with {} # leave it to authorize
config.authorize_with do
is_admin= ADMIN_EMAILS.include?(current_user.email)
if current_user
redirect_to main_app.new_user_session_url unless is_admin
end
end
我在这里遇到的问题是，我甚至无法启动rails服务器，我的意思是当我输入rails server时，我遇到了一些文本错误，只有当我输入内容时才会发生错误这个文件/写这段代码。
这是我在终端中遇到的整个错误：
=> Booting WEBrick
=> Rails 4.0.0 application starting in development on http://0.0.0.0:3000
=> Run `rails server -h` for more startup options
=> Ctrl-C to shutdown server

syntax error, unexpected end-of-input, expecting keyword_end (SyntaxError)错误明确指出其期望end关键字。
在初始化程序文件底部添加end，因为您错过了它。
RailsAdmin.config do |config|
ADMIN_EMAILS= ['youremail@email.com', 'email2@email.com']
config.current_user_method { current_user } # auto-generated
config.authenticate_with {} # leave it to authorize
config.authorize_with do
is_admin= ADMIN_EMAILS.include?(current_user.email)
if current_user
redirect_to main_app.new_user_session_url unless is_admin
