Question

If I try to use bootstrap’s icon class, it doesn’t show correctly.
Anyone knows how to display it?

<%= f.submit nil, :class => 'btn btn-primary', :value => sanitize('<i class="icon-plus icon-white"></i> ') +  'Create!' if @community.new_record? %>

Answer 1

glyphicon-halflings-white.png (for white icons) must be in the Rails app’s app/assets/images directory. Then add <i class="icon-plus icon-white"></i> to your desired view.

To use the icon as a form submit button, pass a block to button_tag:

<%= button_tag(type: 'submit', class: "btn btn-primary") do %>
  <i class="icon-ok icon-white"></i>
<% end %>
