下拉列表中的轨道

Question

    <% form.inputs do %>
      <% @account.account_preference.editorial_attributes.each do |key, value| %>
        <%= account_pref.input "editorial_#{key}".to_sym, :as => :radio, :collection => options_for(Editorial, key.to_sym), :wrapper_html => { :class => "compact" }, :label => key.titleize  %>
      <% end %>
    <% end %>

如何将此下拉列表更改为不带单选按钮的常规下拉列表？

Answer 1

您可以这样进行：

account_pref_options = []
@account.account_preference.editorial_attributes.each do |k,v|
  account_pref_options << [k.titleize, "editorial_#{key}"]
end

然后使用选择标签帮助器。 如果在form_for model do |f| 做标签

<%= f.select :field_name, account_pref_options_options %>

如果带有form_tag标记，请执行

<%= select_tag(:field_name, options_for_select(account_pref_options)) %>
