<div class="col-md-12">
  <div class="group">
    <%= link_to("New group", new_group_path, class: "btn btn-primary pull-right") %>
  </div>
  <table class="table table-hover">
    <thead>
      <tr>
        <td>#</td>
        <td>Title</td>
        <td>Description</td>
      </tr>
    </thead>
    <tbody>
      <% @groups.each do |group| %>
        <tr>
          <td>#</td>
          <td><% link_to(group.title, group_path(group)) %></td>
          <td><% group.description %></td>
          <td>
            <% link_to("Edit", edit_group_path(group), class: "btn btn-sm btn-defalut") %>
            <% link_to("Delete", group_path(group), class: "btn btn-sm btn-defalut",
                        method: :delete, data: {confirm: "Are you sure?" } ) %>
          </td>
        </tr>
      <% end %>
    </tbody>
  </table>
</div>

 

原因1：<%= %>忘记加“=”

原因2：defalut拼写错误
