我有一个同时使用载波和轮胎宝石的应用程序。我遇到的问题是当我尝试这样做时rake environment tire:import CLASS=Website FORCE=true --trace：

** Invoke environment (first_time)
** Execute environment
** Invoke tire:import (first_time)
** Execute tire:import
[IMPORT] Deleting index 'websites'
[IMPORT] Creating index 'websites' with mapping:
{"website":{"properties":{"id":{"type":"integer"},"title":{"type":"string"}}}}
[IMPORT] Starting import for the 'Website' class

轮胎和载波之间似乎存在某种冲突。如果我mount_uploader :screenshot, ScreenshotUploader从我的网站模型中删除，那么 rake 命令将成功。关于这个原因的任何想法以及可能的解决方案可能是什么？

看起来与两个 gem 使用的 serializable_hash 方法存在冲突。Tire 在其 to_hash 方法中使用 serializable_hash，该方法被 Carrierwave 覆盖。我希望这能有所帮助。

# tire-0.4.0/lib/tire/model/search.rb:270
...
def to_hash
  self.serializable_hash
...

# carrierwave-0.6.0/lib/carrierwave/orm/activerecord.rb:46
...
def serializable_hash(options=nil)
...

编辑

你可以试试这个（丑陋的）解决方法。将其放入您的网站模型中：

def to_hash
  self.serializable_hash_copy
end

def serializable_hash_copy(options = nil)
  options = options.try(:clone) || {}

  options[:except] = Array.wrap(options[:except]).map { |n| n.to_s }
  options[:except] |= Array.wrap(self.class.inheritance_column)

  super(options)
end

我希望它有效
