rails 3 array display value

Question

Hi How do i display the value of domain from this array: {:domain=>"www.domain1.com"}, {:domain=>"domain1.com"}, {:domain=>"www.domain2.com"}

I have tried this:

<% @domains.each do |d| %>
    <%= d %><br />
<% end %>

That displays this:

domainwww.shopcms.dk

domaindomain1.com

domainwww.domain2.com

I have also tried to get valeu of domain like this <%= d.domain %> That gives me an error.

Obviously I want to only display the Domain like www.domain1.com

since each element is a hash, if you are sure it only contains one key, you can use

d[:domain]

to get the value and print it.
