データベースに挿入しようとしているモデルメソッドは次のとおりです。

def self.add_documents
  body = Nokogiri :: HTML(open('http://www.someurl.com'))。to_s.to_my_utf8
  Merchant_id = Merchant.find(1)
  Document.create(:merchant_id => Merchant_id、:body => body)
終わり

#config / initializers / string.rb
'iconv'が必要

クラス文字列
  def to_my_utf8
    :: Iconv.conv('UTF-8 // IGNORE'、'UTF-8'、self +'')[0 ..-2]
  終わり
終わり

私はこの問題についてどんな援助も望んでいます!
