ruby-on-rails - 在 Rails 中设置动态数据目标和 id

Question

我正在尝试设置模态的动态数据目标和相应的动态 div id。我遇到了语法错误，但似乎无法找出原因。

我尝试使用“myModal<%= Gift.id %>”作为数据目标和 div 的唯一名称。

我收到的错误:

/Users/bvlaar/Sites/Redwood/app/views/gifts/index.html.erb:12: syntax error, unexpected $undefined, expecting '}'
... :class => "btn btn-primary", \'data-type\' => "html" } %></...
...                               ^
/Users/bvlaar/Sites/Redwood/app/views/gifts/index.html.erb:25: syntax error, unexpected keyword_end, expecting ')'
';       end 
            ^
/Users/bvlaar/Sites/Redwood/app/views/gifts/index.html.erb:32: syntax error, unexpected keyword_ensure, expecting ')'
/Users/bvlaar/Sites/Redwood/app/views/gifts/index.html.erb:34: syntax error, unexpected keyword_end, expecting ')'

我的 Index.html.erb 页面如下所示:

<%= title "Redwood | Gifts" %>
<div class="container">
    <div class="row">
        <% @gifts.each do |gift|  %>
        <div class="col-sm-6 col-md-4">
            <div class="thumbnail">
                <%= image_tag gift.picture.url(:medium) %>
                <div class="caption">
                    <h3><%= gift.name %></h3>
                    <h4><%= gift.merchant.name %></h4>
                    <p><%= gift.description %></p>
                    <p><%= link_to 'Buy', gift_path(gift), { :remote => true, 'data-toggle' =>  "modal", 'data-target' => "#myModal<%= gift.id %>", :class => "btn btn-primary", 'data-type' => "html" } %></p>
                </div>
                <!-- Modal -->
                    <div class="modal fade" id="myModal<%= gift.id %>">
                        <div class="modal-dialog">
                            <div class="modal-content">
                                <%= render partial: 'show', :locals => { :gift => gift } %>
                            </div>
                        </div>
                    </div>
                <!-- End of Modal -->
            </div>
        </div>
        <% end %>
    </div>
</div>

我在 SO 上看到过其他几个类似的问题，但它们似乎不起作用。

谢谢

Answer 1

尝试将 link_中的以下内容更改为“购买”

来自

'data-target' => "#myModal<%= gift.id %>"

至

'data-target' => "#myModal#{gift.id}"
