升级到Rails 3.1.0后，带有atom_feed的ActionView :: Template :: Error(错误的参数数量(1表示0)) [英] ActionView::Template::Error (wrong number of arguments (1 for 0)) with atom_feed after upgrading to rails 3.1.0

问题描述

我刚刚将Rails应用程序从3.0.7版本升级到了候选发布版本3.1.0，我在原子供稿生成器中遇到了一个奇怪的错误:

I've just upgrade my rails application from the 3.0.7 version to the release candidate 3.1.0 and I got a strange error located in my atom feed builder:

ActionView::Template::Error (wrong number of arguments (1 for 0)):
1: atom_feed do |feed|
2:   feed.title("site name")
3:  
4:   for post in @posts
app/views/posts/index.atom.builder:1:in `_app_views_posts_index_atom_builder___1517323884_2197638100'

在atom_feed方法中似乎需要一个参数，但是我尝试在其中添加一些内容，但并没有解决问题.在升级之前就可以了.

It seems to need an argument in the atom_feed method, but I tried to put something in it and it hasn't fixed the problem. It worked before the upgrade.

推荐答案

Builder 3.0与ruby 1.8.7上的fast_xs 0.8.0不兼容，并且会出现此错误.也许您已经安装了该软件? (还请注意，Hpricot捆绑了fast_xs 0.8.0)

Builder 3.0 is not compatible with fast_xs 0.8.0 on ruby 1.8.7 and will give this error. Perhaps you have that installed? (also note that Hpricot bundles fast_xs 0.8.0)

(edit :)您可以通过将其拖放到配置目录中来进行猴子修补:

(edit:) you can monkey patch it by dropping this in your config dir:

class String
  def fast_xs_absorb_args(*args); fast_xs; end
  alias_method :to_xs, :fast_xs_absorb_args
end
