Question

我从Rails 3.1.3迁移到3.2.1并在加载主页时出现以下错误：

PGError: ERROR:  relation "translations" does not exist
LINE 4:              WHERE a.attrelid = '"translations"'::regclass
                                    ^
:             SELECT a.attname, format_type(a.atttypid, a.atttypmod), d.adsrc, a.attnotnull
          FROM pg_attribute a LEFT JOIN pg_attrdef d
            ON a.attrelid = d.adrelid AND a.attnum = d.adnum
         WHERE a.attrelid = '"translations"'::regclass
           AND a.attnum > 0 AND NOT a.attisdropped
         ORDER BY a.attnum

当globalize3 gem尝试构建page_meta_tags和page_meta_tag_translations表之间的关系时，会发生这种情况。在Rails 3.1.3上一切正常。是否可能是由于新的Active Record和globalize3不兼容？任何人都有同样的事情吗？

class PageMetaTag < ActiveRecord::Base
  translates :title, :description, :keywords

  accepts_nested_attributes_for :translations
end

尝试使用globalize3 beta：

gem 'globalize3', '0.2.0.beta8'

迁移到Rails 3.2.1后，关系“转换”不存在
