ruby-on-rails - Rails - 添加自定义项目以选择

Question

我有这行代码：

<%= select "family", "num_of_children", (1..10), { :include_blank => true } %>

我想在列表末尾添加一项。在这种情况下：我想要一个“更多”选项作为最后一项。我怎样才能做到这一点？

Answer 1

将范围转换为数组，然后附加'more'到它：

<%= select "family", "num_of_children", (1..10).to_a << 'more', { :include_blank => true } %>

Answer 2

<%= select "family", "num_of_children", (1..10).to_a + [['more', '11']], { :include_blank => true } %>
