如何在方法中使用firebase而不是在本地使用firebase，如示例所示？例如：@firebase，请参见以下网址： http://bpaste.net/show/501b6a67c8d4

或 -

require 'sinatra'
require 'firebase'
require 'bundler'
Bundler.require

# Configure database
configure do
  @base_uri = 'https://veriyo.firebaseio.com/'
  @firebase = Firebase::Client.new(@base_uri)
end

# Display homepage
get '/' do
  erb :index
end

post '/search' do
  @username = params["username"]
  redirect to("/user/#{@username}")
end

get '/user/:username' do
  response = @firebase.push("todos", { :name => @username })
  'hello'
end

@ firebase变量的属性无法访问 - #<NoMethodError: undefined method push'代表nil：NilClass＆gt;`
