I have this form:
<%= form_tag(user_pages_path(current_user), :method => \"get\") do %> <%= text_field_tag :update, \'yes\', type: \"hidden\" %>
You can use button_tag instead of submit_tag:
button_tag
submit_tag
<%= button_tag(type: "submit", class: "btn btn-default") do %> Update list <i class="icon-repeat"></i> <% end %>
