acts_As_taggabe_on更改標籤大小寫 - 可能緩存問題但不確定

我正在使用actsastaggableon gem。出於某種原因，系統將標籤「Python」保存爲「python（小寫）」。由於我驗證用戶只能輸入特定的標籤，系統將標籤保存爲「python」會導致一些問題。以下是我的服務器日誌。第一行是在所有驗證運行（它通過）之後tag_list的puts語句。之後，服務器正在做一些奇怪的事情，並將「Python」變成「python」。這可能與緩存有關，因爲我曾經有一個名爲「python」的標籤，但我不再這樣做。如何解決這個問題，而不會嚴重改變我的緩存設置？acts_As_taggabe_on更改標籤大小寫 - 可能緩存問題但不確定

你有沒有設置這個地方：

ActsAsTaggableOn.force_lowercase = true

如果從而迫使小寫

如果你沒有這樣的設置，可以是另一個可能的問題，如果你正在使用MySQL的db可以在這裏找到： https://github.com/mbleigh/acts-as-taggable-on/issues/259

class EditTagTableToBeCaseSensitive < ActiveRecord::Migration 
    def up 
    @sql = "ALTER TABLE `tags` CHANGE `name` `name` VARCHAR(255) BINARY DEFAULT NULL;" 
    execute @sql 
    end 

    def down 
    @sql = "ALTER TABLE `tags` CHANGE `name` `name` VARCHAR(255) DEFAULT NULL;" 
    execute @sql 
    end 
end
