Ruby on rails HAML和Stripe的形式为，我不断得到一个编译错误。有什么明显的问题吗？

我刚刚将应用程序切换到rails 3.1和ruby 1.9。我还通过他们的API集成了Stripe。也许这会引起问题？ 我一辈子都搞不懂这个表格有什么问题。它说第一个错误在第3行的

else

语句中（这是一个编译错误，下面是完整的错误细节）。所有的缩进都是一致的，我一行一行地检查并修复了它。让我知道我是否应该发布更多信息，比如我的GEM文件或其他东西

下面是有问题的表单：

=声明 您正在HAML中使用Javascript数组表示法。HAML使用Ruby计算=（表达式）：

所以这是错误的：

= 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 代码行不产生输出，所以使用-而不是=

- if 
    %h1 Sign up
- else
    %h1 Edit

---

好的，错误的数量已经减少了，但是我仍然在第三行得到

编译错误

…

语法错误，意外的kELSE

。我已经编辑了这个问题，包括编辑过的表单，去掉了javascript数组notationupdated答案——movember每年都会留胡子一次（不允许留到12月）啊，这就成功了，出于某种原因，我错误地认为在rails 3.1中，haml中的所有内容都应该使用等号。不幸的是，注重细节不是我的强项。thakns对于helpNah来说，他们实际上只是改变了form_标记的工作方式——它以前是不一致的。我刚刚发现的另一件事——你原来的哈希符号是正确的——例如，在Ruby 1.9中，{注意：'hello'}和{：注意=>'hello'}是一样的
