sinatra - how to connect to Twilio API with ruby -

sorry basic question should easy answer!

using ruby , sinatra, trying connect, via api, details of calls. prescribed way twilio seems be:

@client = twilio::rest::client.new account_sid, auth_token # loop on calls , print out property each 1 @client.account.calls.list.each |call| puts call.sid puts call.from puts call.to 

which works fine , "puts" data in terminal. want print results on html page, changed line

@client.account.calls.list.each |call| 

to

@calls = @client.account.calls.list 

and removed last 3 lines of code block above, ie. "puts"

then, attempting print on index page included following:

<% @calls.each |call| %>  <h4 style="color: #ff0000;"><%= params['msg'] %></h4>  <ul>   <li> <%= call.from %> </li>   <li> <%= call.to %> </li>   </ul> <% end %> 

the error message says:

undefined method `each' nil:nilclass 

so not connecting twilio seems though code same above connect , produce required results.

any ideas? gratefully received.

in sinatra, not use instance variables store connection objects , similar stuff. instead of @call, use set method enables user set such objects different variables.

the calls.list method, per code, defined in twilio::rest::listresource module. returns array , so, second part of code (in index.erb) correct.

the problem is, when start using instance variables storing connection object, gets reset in route , that's what's happening inside get .. end block.

change code to:

set :client, twilio::rest::client.new(account_sid, account_pass) # now, setting can accessed settings.client  '/calls'   @calls = settings.client.account.calls   erb :index end  # index.erb  <% @calls.each |call| %> ... <% end %> 

this should work.
