Question

我想在每个循环中显示图像，图像由paperclip gem上传。真正的道路是

/system/users/images/000/000/035/original/lovecupcake.jpg

当我使用它时，这工作正常

rails code <%= image_tag @user.image.url(:medium) %>  

output <img alt="Lovecupcake" src="/system/users/images/000/000/035/original/lovecupcake.jpg">

它显示我的图像但是当我应用循环

<% @result.each do |r| %>
            <tr>

                <td> 
                    <% image = r['image_file_name'] %>
                    <%=image_tag r['id'].image.url %>

                    </td>
                </td>

            </tr>
        <% end %>

检查结果后

它没有显示我的图像

我错了

Answer 1

所以你的@result是一组用户。只需致电<%= r.image.url(:medium) %>

回形针显示图像网址是undefine
