Question

关于MySQL的字符集＆＃34; utf8mb4＆＃34;，
rails console运行良好。

<pre>
<p style="background-color:#FFFFFF;border:1px solid #999999;padding:5px;">
10191% rails c -e production                                                                                                                                   Loading production environment (Rails 4.2.5)
irb(main):001:0> skin = Skin.first
  Skin Load (203.9ms)  SELECT  `skins`.* FROM `skins`  ORDER BY `skins`.`id` ASC LIMIT 1
=> #<Skin id: 1, created_at: "2015-12-19 07:59:48", updated_at: "2015-12-19 08:08:34", name: "", file: "standard.css", expression: "">
irb(main):002:0> skin.name = 'たのしい''
irb(main):003:0'
irb(main):004:0' '
=> "たのしい\n\n"
irb(main):005:0> skin.name = 'たのしい'
=> "たのしい"
irb(main):006:0> skin.save
   (112.3ms)  BEGIN
  SQL (115.0ms)  UPDATE `skins` SET `name` = 'たのしい', `updated_at` = '2015-12-19 11:56:18' WHERE `skins`.`id` = 1
   (105.7ms)  COMMIT
=> true
</p>
</pre>

但是＆＃34; rake db：seed_fu＆＃34;没有像这样运行得很好。

<pre>
<p style="background-color:#FFFFFF;border:1px solid #999999;padding:5px;">
10192% rake db:seed_fu RAILS_ENV=production
== Seed from /Users/js/work/picrating/db/fixtures/production/publish.rb
 - Publish {:id=>1, :name=>"公開"}
 - Publish {:id=>2, :name=>"非公開"}

== Seed from /Users/js/work/picrating/db/fixtures/production/skin.rb
 - Skin {:id=>1, :name=>"standard", :file=>"standard.css", :expression=>"レギュラー"}
 - Skin {:id=>2, :name=>"light", :file=>"light.css", :expression=>"たのしい"}

</p>
</pre>

我不知道，甚至rails控制台运行良好，
但db：seed_fu运行不好发生了什么事？

Answer 1

这是一个充分的线索吗？

在application_controller.rb

  def configure_charsets
    response.headers["Content-Type"] = "text/html; charset=utf-8"
    suppress(ActiveRecord::StatementInvalid) do
      ActiveRecord::Base.connection.execute 'SET NAMES utf8mb4'
    end
  end

在MySQL的字符集＆＃34; utf8mb4＆＃34;，甚至rails控制台运行良好，但seed_fu运行不好
