Rails: Can't add CSS class from variable in link_to

Question

SyntaxError occurs when:

<% @list1.each do |list| %>
  <div class="well well-sm">
    <%= list.test_name %> <%= link_to 'Do It', '#', class: <%= list.test_type %>
  </div>
<% end %>

Tried also class: <%= #{list}.test_type %> and so on... what's wrong with it?

You have excess erb open tag <%=, instead:

<%= list.test_name %> <%= link_to 'Do It', '#', class: <%= list.test_type %>
^^^open          close^^  ^^open                                     ^^^open       close^^

use:

<%= list.test_name %> <%= link_to 'Do It', '#', class: list.test_type %>

I suggest you read An Introduction to ERB Templating

try this:

 <%= link_to 'Do It', '#', class: list.test_type  %>

or

<%= link_to 'Do It', '#', class: "#{list.test_type}" %>
