关系“翻译"；迁移到Rails 3.2.1后不存在 [英] Relation "translations" does not exist after migrating to Rails 3.2.1

问题描述

我从Rails 3.1.3迁移到3.2.1，并在加载主页时遇到以下错误:

I migrated from Rails 3.1.3 to 3.2.1 and got the following error when loading the home page:

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试图建立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.可能是由于新的Active Record和globalize3不兼容造成的吗?任何人都有同一件事吗?

This happens when globalize3 gem tries to build the relation between page_meta_tags and page_meta_tag_translations tables. Everything worked fine on Rails 3.1.3. Can it be due to new Active Record and globalize3 incompatibility? Anyone has the same thing?

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

  accepts_nested_attributes_for :translations
end

推荐答案

尝试使用globalize3 beta:

try using globalize3 beta:

gem 'globalize3', '0.2.0.beta8'
