我刚刚尝试过，rails_admin在保存包含变音符号的字符串时遇到了问题（例如“ü，ö，ä ...”）。模型已保存到数据库，但后续屏幕失败。
incompatible character encodings: UTF-8 and ASCII-8BIT
Extracted source (around line #17):
14: = menu_for((@abstract_model ? (@object.try(:persisted?) ? :member : :collection) : :root), @abstract_model, @object)
15: = content_for :contextual_tabs
16: = yield
17:
18: %footer
19: %p © RailsAdmin 2012
我还尝试使用 before_save 钩子对 utf8 中的字符串进行编码，但是在按下保存后，错误仍然存在：
我的模特
# encoding: utf-8
require 'carrierwave/orm/activerecord'
class Product < ActiveRecord::Base
mount_uploader :img_small, ProductImgSmallUploader
mount_uploader :img_large, ProductImgLargeUploader
attr_accessible :img_small, :img_small_cache, :remove_img_small
attr_accessible :img_large, :img_large_cache, :remove_img_large
attr_accessible :title_de, :title_en, :description_de, :description_en, :visible
before_save do
[:title_de,:title_en,:description_de,:description_en].each do |arg|
if self.try arg
self.send("#{arg}=", self.send(arg).encode('UTF-8'))
end
end
end
end
关于如何在我这边解决它的任何建议？还是我必须分叉宝石？
