[Rails] passing value from controller to view

[amvis]

 *require "rubygems"
 require "twitter"

def login

Twitter.configure do |config|
         config.consumer_key = ''
         config.consumer_secret =  ''
         config.oauth_token = ''
         config.oauth_token_secret = ''
      end

 @client = Twitter::Client.new
end*

In my *tweet.html.erb*

*<% @client.**home_timeline**.each do |tweet| %> 
 
&nbsp; <%= tweet.user[:screen_name] %>&nbsp;<br/> 
<%= tweet.text %><br/> 

<% end %> *


Here i got the* undefined method `home_timeline' for nil:NilClass,* Why 
cannot access that *@client* in view from controller?*
*
Thankyou
vishnu*
