我有一个主要细节工作,但当我转到编辑表单时,选择字段未显示为数据库中记录的,它显示第一个option_for_select
:
<div class='fields'>
<div class='span-24 last'>
<div class='span-11'>
<%= f.select :ordem, options_for_select([["0", 0], ["1", 1], ["2", 2], ["3", 3], ["4", 4], ["5", 5]]) %>
</div>
<div class='span-8'><%= f.text_field :opcao %></div>
<div class='last'>
<%= f.hidden_field :_destroy %>
<%= link_to_function '(X)', "remove_fields(this)" %>
</div>
</div>
</div>
那么我该如何显示此选择的录制内容呢?
答案 0 :(得分:1)
只需添加一个包含选项ID的:selected
选项即可:
f.select :ordem, [["0", 0], ["1", 1]], {:selected => '1'}
