Question

我正在使用bootstrap，我有一个链接，可以从images#show重定向到home#index操作。该链接以haml：

编写

- url = @entry.class.to_s.downcase.singularize
    = link_to(send("#{url}_path", @entry), data: { 'type' => @entry.class.to_s.downcase }) do
        = yield

目前，home#index显示图像列表，单击图像时，上面写的链接会将用户重定向到特定图像Ex：images/1的视图。也就是说@entry表示图像，点击时会重定向到特定图像或（@entry）。

我不想离开主页（home#index），我只想显示一个模态视图，该视图会考虑点击哪些图像（或@entry）。当单击上面的链接时，如何修改此链接并添加将显示引导模式的代码？我应该遵循哪些其他步骤？我只是需要帮助才能显示模态。

这是我的追踪：

一种选择是使用exec_then_eval('''x = 4 y = 5 x + y''')) # 9 exec_then_eval('''x = 4 y = 5;x + y''')) # 9 exec_then_eval('''x = 4 y = 5;( x + y * 2)''') # 14模板并将您的链接更改为使用js选项：

remote: true

接下来在控制器中，响应类型可以设置为<%- @images.each do |image| -%> <%= link_to '...', image_path(image) remote: true %> <%- end -%> <div id="modals"></div>（可能还是保持js选项的好主意）：

html

然后在处理respond_to do |format| format.js end：

的模板中

js

最后为模态添加部分并设置所需的任何标记：

// app/views/images/show.js.erb
$("#modals").html('<%= j render "images/modal", image: @image %>');
$('#modals .modal').modal();
$('#modals .modal').modal('.toggle');

如何在我的情况下显示引导模式？
