Question

I have an hash like this:

@json = [{"id"=> 1, "username" => "Example"}, {"id"=> 2, "username" => "Example 2"}]

I want to do something like this:

<ul>
    <% @json.each do |user| %>
    <li><%= user.username %></li>
    <% end %>
</ul>

and it would output a list with the two usernames.

Just tried this in IRB:

json2 = [{"id"=> 1, "username" => "Example"}, {"id"=> 2, "username" => "Example 2"}]
irb(main):076:0> json2.each do |user|
irb(main):077:1* user["id"]
irb(main):078:1> end
=> [{"id"=>1, "username"=>"Example"}, {"id"=>2, "username"=>"Example 2"}]
irb(main):079:0>

Answer 1

What you have there is a Hash, not a User object. Therefore, you must access the username using the index operator ([]):

<ul>

<% @json.each do |user| %>
  <li><%= user["username"] %></li>
<% end %>

</ul>
