我试图将show action数据放在模态弹出窗口中。在视图中有一个客户端数据表，每当我点击show按钮时它会弹出第一个客户端的数据。我需要有关如何以及在何处放置循环的帮助，以便每次我都可以访问不同的相关数据。
This is the code
<% @clients.each do |client| %>
<tr class="even pointer">
<td class="a-center "><%= client.name %></td>
<td class="a-center "><%= truncate(client.email, :length => 15)%></td>
<td class="a-center "><%= client.mobile_number %></td>
<td class="a-center "><%= client.car_model %></td>
<td class="a-center "><%= client.date_of_purchase.try(:strftime , '%d %b %Y') %></td>
<td class="a-center "><%= client.insurance_expiry_date.try(:strftime , '%d %b %Y') %></td>
<td class="a-center "><%= client.warranty_expiry_date.try(:strftime , '%d %b %Y') %></td>
<td class="a-center "><%= client.lifestyle_manager_name %></td>
<td class="a-center "><%= truncate(client.lifestyle_manager_email, :length => 15) %></td>
<td class="a-center "><%= client.lifestyle_manager_mobile_number %></td>
<td><a href="#" data-toggle="modal" data-target="#myModal">Show</a><td>
<!-- Modal -->

您无法在div内放置tr元素。同样在你的情况下，你需要一些模态，你需要一些东西来唯一地识别相应的模态。将client id附加到模态ID，您可以使其正常工作。
<% @clients.each do |client| %>
<tr class="even pointer">
<td class="a-center "><%= client.name %></td>
<td class="a-center "><%= truncate(client.email, :length => 15)%></td>
<td class="a-center "><%= client.mobile_number %></td>
<td class="a-center "><%= client.car_model %></td>
<td class="a-center "><%= client.date_of_purchase.try(:strftime , '%d %b %Y') %></td>
<td class="a-center "><%= client.insurance_expiry_date.try(:strftime , '%d %b %Y') %></td>
<td class="a-center "><%= client.warranty_expiry_date.try(:strftime , '%d %b %Y') %></td>
<td class="a-center "><%= client.lifestyle_manager_name %></td>
<td class="a-center "><%= truncate(client.lifestyle_manager_email, :length => 15) %></td>
<td class="a-center "><%= client.lifestyle_manager_mobile_number %></td>
<td><a href="#" data-toggle="modal" data-target="#myModal-<%= client.id %>">Show</a><td>
<td><%= link_to 'Edit', edit_client_path(client) %></td>
<td><%= link_to 'Delete', client, method: :delete, data: { confirm: 'Are you sure?' } %></td>
</td>
</td>
</tr>

虽然我不建议将模态放在循环中。它会使html更大，并会影响加载时间。我建议你在循环外编写模态，并使用javascript修改模态中的值。
