Campaign_groups＃show中的語法錯誤

Question

我已經看了很多，只是找不到語法錯誤，我不斷得到：

compile error
/home/durrantm/code/it_trunk/webapp/app/views/campaign_groups/_cgs_overview.html.erb:36: syntax error, unexpected kELSE, expecting ')'
;  else ; @output_buffer.concat "\n  ...
       ^
/home/durrantm/code/it_trunk/webapp/app/views/campaign_groups/_cgs_overview.html.erb:40: syntax error, unexpected kEND, expecting ')'
;  end ; @output_buffer.concat "\n\n"
      ^
/home/durrantm/code/it_trunk/webapp/app/views/campaign_groups/_cgs_overview.html.erb:43: syntax error, unexpected kENSURE, expecting ')'
/home/durrantm/code/it_trunk/webapp/app/views/campaign_groups/_cgs_overview.html.erb:45: syntax error, unexpected kEND, expecting ')'

該頁面的完整代碼（_cgs_overview.html.erb）為：

<% if @campaign_group.campaigns.count > 0 %>
    <%=# render :partial => 'show_offer_images' %>
    <div class="overview">

      <table class="show_activity show_overview">
        <tr>
          <th>Unique Shoppers</th>
          <td id="overview-shoppers" class="clearable">-</td>
        </tr>
        <tr>
          <th>Issuances</th>
          <td id="overview-issuances" class="clearable">-</td>
        </tr>
        <tr>
          <th>Redemptions</th>
          <td title="Redemption rate does not include informational campaigns" id="overview-redemptions" class="clearable">-</td>
        </tr>
        <tr>
          <th>Total Cost</th>
          <td id="overview-cost" class="clearable">-</td>
        </tr>
        <tr>
          <th>Products</th>
          <td id="overview-products" class="clearable">-</td>
        </tr>
      </table>
    </div>
    <div style="clear:both;"></div>

    <div style="width:300px; padding-bottom: 10px">
      <%=# link_to("<<", campaign_group_path(params[:id], :offer_images_offset_for_pagination => @previous_images_to_paginate )) %>&nbsp;&nbsp;
      <%=# link_to(">>", campaign_group_path(params[:id], :offer_images_offset_for_pagination => @next_images_to_paginate )) %>&nbsp;&nbsp;
      <%=# link_to(">ajax>", :remote => true, :action => 'show_offer_images', :campaign_group_id => params[:id], :offer_images_offset_for_pagination => @next_images_to_paginate ) %>
    </div>

<% else %>
    <p style="font-size:120%;font-style:italic;margin:140px 0 160px;">
      There are no campaigns in this group.
    </p>
<% end %>

如果讓erb通過-x開關向您顯示紅寶石代碼，您將看到

... _erbout.concat((# render :partial ...)); _erbout.concat "\n"

注意#哈希如何注釋掉整行代碼。 這條線和其他三個類似的詞是“ expecting ')'的原因。

搜索erb注釋指向在erb中添加注釋的最佳方法，在該方法中 ，我們得知您應將<%=# ... %>替換為<%#= ... %>
