Double less than Ruby access -



Double less than Ruby access -

i still new ruby , wondering how access info element stored in "double less than" structure:

@email << {:envelope => envelope, :body => body}

if do

<% @results.email.each |result| %> <%= result %> <% end %>

i get

bodytest test envelope#<struct net::imap::envelope date="tue, 28 jun 2011 09:20:35 -0700", subject="test test", from=[#<struct net::imap::address name="some name", route=nil, mailbox="someinbox", host="somehost.com">], sender=[#<struct net::imap::address name="somename", route=nil, mailbox="somebox", host="somedomaincom">], reply_to=[#<struct net::imap::address name="someperson", route=nil, mailbox="somemailbox", host="somehost.com">], to=[#<struct net::imap::address name=nil, route=nil, mailbox="thisinbox", host="somehost.com">], cc=nil, bcc=nil, in_reply_to=nil, message_id="<c4427977-8a42-46e4-adb4-1ae88ed9ccde@mehost.com>">

how access each element, body, envelope, sender (within envelope)? result.body doesn't work, nor result[body].

thanks!

you should utilize result[:body] , not result[body]. body variable, whereas :body symbol (similar string).

notice have stored values in hash symbols. {:envelope => envelope; :body => body} storing content of variable envelope (the 1 on right) value against key :envelope (and same body , :body).

note: nice write on how symbols differ strings - http://www.robertsosinski.com/2009/01/11/the-difference-between-ruby-symbols-and-strings/
