我从RoR 4.0.4更新到4.1.1以应用最新的安全补丁，看起来pg_search破了。
这是一个错误：
PG :: SyntaxError：ERROR：语法错误在或附近＆＃34; AS＆＃34; 第1行：...... sh＆＃39;，＆＃39;＆＃39;＆＃39; ＆＃39; || unaccent（＆＃39; banner＆＃39;）|| ＆＃39; ＆＃39;＆＃39;）），0）））AS pg_sear ...
我通过ajax搜索，但我不认为这是基于上述输出的问题。我也使用了will_paginate，但我使用的分支应该用rails 4.1.x和pg_search解决以前的问题。
gem 'will_paginate', :git => 'https://github.com/nazgum/will_paginate.git' #until rails 4.1 will_paginate fixed
这是我执行搜索的代码模型：
include PgSearch
pg_search_scope :search, against: [:title, :body],
using: {tsearch: {dictionary: "english"}},
ignoring: :accents
def self.text_search(query)
if query.present?
search(query)
else
scoped
end
end
在RoR版本爆发之前一切正常 - 希望有人可能会有一些建议。
这里是完整的堆栈跟踪：

答案 0 :(得分：18)
@supports.count(:all)应该有效，{4.1}
@supports.count语法
答案 1 :(得分：3)
有一个很好的对话here来澄清问题。
答案 2 :(得分：-3)
这很奇怪 - 当我打电话时
=@supports.count
生成错误但它是一个有效的对象。这有点hacky但现在正在努力：
=@supports.to_a.count
