You can do it this way
<% @comments.each do |comment| %>
<%= render "/talk/partials/comment_2014", comment: comment, votes: @votes %>
<% end %>
Or
<% @comments.each do |comment| %>
<%= render partial: "/talk/partials/comment_2014", locals: { comment: comment, votes: @votes } %>
<% end %>
Notice in the second way the comment is inside the locals.
