html - Rails new line on

Question

I am trying to figure out a way I can have a new line in a cell so it is displayed in this format:

Phone Number 1
Phone Number 2
Phone Number 3

Let me show you the code that I have now so that you may understand my problem:

<tbody>
        <% @books.each do |book| %>
  <% record = AddressBookController.address_book(book.id) %>
        <tr>
            <td><%= record['last_name'] %></td>
            <td><%= record['phone_numbers'].join ', ' %></td></td>
        </tr>
        <% end %>
</tbody>

The .join will break up the array and display it like this: Phone Number 1, Phone Number 2, Phone Number 3

How can I make it show like first example in this post?

Answer 1

您可以使用<br />. 以下应该有效：

<td><%= raw record['phone_numbers'].join('<br />') %></td>

另外，请使用raw帮助程序，以免输出被转义。

Answer 2

我猜你正在寻找这个：

<tbody>
    <% @books.each do |book| %>
    <% record = AddressBookController.address_book(book.id) %>
        <% record['phone_numbers'].each do |number| %>
        <tr>
          <td><%= record['last_name'] %></td>
          <td><%= number %></td></td>
        </tr>
        <% end %>
    <% end %>
</tbody>
