HAML和条纹在form_for中，我不断收到编译错误。有什么明显的错误吗？

我只是将我的应用程序切换到rails 3.1和ruby 1.9。我也通过他们的API整合了Stripe。也许这是造成问题？ 我无法弄清楚我的生活这个表格的问题是什么。它说第一个错误在第3行与else声明（这是一个编译错误，下面的完整错误细节）。所有的缩进都是一致的，我逐行进行修复。让我知道是否应该发布更多信息，比如我的gemfile或其他东西。HAML和条纹在form_for中，我不断收到编译错误。有什么明显的错误吗？

这里是有问题的形式：

=if 
    %h1 Sign up 
=else 
    %h1 Edit 
=form_for(@user) do |f| 
    =render "shared/error_messages", :target => @user 
    =f.hidden_field :stripe_card_token 
    %dl 
     =if signed_in? 
      %dt.field=f.label :avatar 
      %dd.field=f.file_field :avatar 
     %dt.field=f.label :name 
     %dd.field=f.text_field :name 
     %dt.field=f.label :email 
     %dd.field=f.text_field :email 
     =if @user.new_record? 
      %dt.field=f.label :password 
      %dd.field=f.password_field :password 
     =if @user.stripe_card_token.present? 
      %p Credit card has been provided. 
     =else 
      %div.field 
       =label_tag :card_number, "Credit Card Number" 
       =text_field_tag :card_number, nil, name:nil 
      %div.field 
       =label_tag :card_code, "Security Code on Card (CVV)" 
       =text_field_tag :card_code, nil, name:nil 
      %div.field 
       =label_tag :card_month, "Card Expiration" 
       =select_month nil, {add_month_numbers: true}, {name: nil, id: "card_month"} 
       =select_year nil, {start_year: Date.today.year, end_year: Date.today.year+15}, {name: nil, id: "card_year"} 
      %div#stripe_error 
       %noscript JavaScript is not enabled and is required for this form. First enable it in your web browser settings. 
    .actions 
     =f.submit((defined?(editing) ? "Update" : "Sign Up"))

以下是错误：

感谢所有

更新1 ...新的形式，而不JavaScript数组符号：

=if 
    %h1 Sign up 
=else 
    %h1 Edit 
=form_for(@user) do |f| 
    =render "shared/error_messages", :target => @user 
    =f.hidden_field :stripe_card_token 
    %dl 
     =if signed_in? 
      %dt.field=f.label :avatar 
      %dd.field=f.file_field :avatar 
     %dt.field=f.label :name 
     %dd.field=f.text_field :name 
     %dt.field=f.label :email 
     %dd.field=f.text_field :email 
     =if @user.new_record? 
      %dt.field=f.label :password 
      %dd.field=f.password_field :password 
     =if @user.stripe_card_token.present? 
      %p Credit card has been provided. 
     =else 
      %div.field 
       =label_tag :card_number, "Credit Card Number"

回答：

=语句

您使用Javascript数组表示法中HAML。 HAML使用Ruby来评估=（表达）：

因此，这是错误的：

= select_month nil, {add_month_numbers: true}, {name: nil, id: "card_month"}

应该是：

= select_month nil, { :add_month_numbers => true}, { :name => nil, id => "card_month" }

Else语句

的代码行不产生输出，所以使用 - 而不是=

- if 
    %h1 Sign up 
- else 
    %h1 Edit

以上是 HAML和条纹在form_for中，我不断收到编译错误。有什么明显的错误吗？ 的全部内容， 来源链接： utcz.com/qa/258868.html
