Ruby on rails 仅在选择第一个值时选择标记

我在rails select标记上遇到问题。在这两种情况下，select_标记都会传递数组中的第一项，无论选择了什么

用户地址数组来自我的一个型号，交付计划只有以下两个选项。我一直在阅读文档，但每当我尝试添加一个选定的=>'plan'时，总是会出现一个错误

有人能就正确的语法提出建议吗

  <<%= form_tag charges_path, id: 'chargeForm' do %>

                        <%= hidden_field_tag 'stripeToken' %>
                        <%= hidden_field_tag 'stripeEmail', current_user.email %>
                        <%= hidden_field_tag 'amount', final_charge %>
                        <%= text_field_tag 'tax', tax_amount %>
                         <b><%= label_tag 'Select a shipping address:' %></b>
                            <%= select_tag 'address_id', options_for_select(user_address.collect{ |address| [address.full_street_address, address.id]},) %>
                        <b><%= label_tag 'Select a delivery plan:' %></b>&nbsp;
                            <%= select_tag 'plan',["One Time Order","Weekly Subscription"] %>
                        <%= hidden_field_tag 'chickenVegetables_quantity', chickenVegetables_quantity %>
                        <%= hidden_field_tag 'chickenRice_quantity', chickenRice_quantity %>
                        <%= hidden_field_tag 'beefCouscous_quantity', beefCouscous_quantity %>
                        <%= hidden_field_tag 'beefVegetables_quantity', beefVegetables_quantity %>
                        <%= hidden_field_tag 'user_id', current_user.id %>


                        <button id="btn-buy1" type="button" class="button i-submit">
                            Checkout
                        </button>
                        <script>
                        var handler = StripeCheckout.configure({
                            key: '<%= Rails.configuration.stripe[:publishable_key] %>',
                            email: '<%=current_user.email%>',
                            token: function(token, arg) {
                                document.getElementById("stripeToken").value = token.id;
                                document.getElementById("stripeEmail").value = token.email;
                                document.getElementById("chargeForm").submit();
                            }
                        });
                        document.getElementById('btn-buy1').addEventListener('click', function(e) {
                            handler.open({
                                name: 'Name',
                                description: 'Purchase',
                                amount:  document.getElementById("amount").value
                            });
                            e.preventDefault();
                        })
                        </script>
                        <% end %>

结束

如果您浏览了有关选项的文档，您会发现如果您需要默认选择一个选项，则必须将其作为第二个参数传递给选项

所以在你的情况下是这样的

<%= select_tag 'address_id', options_for_select([user_address.collect{ |address| [address.full_street_address, address.id]}],@selected_address.id) %> # if user address to be selected is @selected_address
<%= select_tag 'plan',options_for_select(["One Time Order","Weekly Subscription"],"Weekly Subscription")%> # to select 2nd option

它适用于订阅，但我在@selected_address上得到了一个未定义的nil:NilClass错误方法'id'。id@selected_address需要是对象，我想在你的情况下，它应该是UserAddress的对象。我根据惯例猜测这个模型。刚刚再次选中，对于“计划”，它现在只通过第二个选项。如何传递用户选择的内容？传递还是选择？传递。我希望用户选择和选项，并将其传递到表单中
