Question

我有关于导出excel用户列表的操作的以下方法：

def users_report
    @users = Kid.where(confirmation_token: nil).paginate(:page => params[:page], :per_page => 30)
    @userxls = Kid.where(confirmation_token: nil)
    respond_to do |format|
        format.html
        format.xls { send_data @userxls.to_csv({col_sep: "\t"}) }
    end
end

在我的模型上，to_csv方法：

def self.to_csv(options = {})
    CSV.generate(options) do |csv|
    csv << ["Name", "Surname", "E-mail", "Age", "School", "Class", "Native Language", "Practised Language", "Conversations same Native", "Convserations different Native", "Message same Native", "Message different Native", "Posts", "Clossed/Finished calls", "Missed calls", "Connections per Week", "Nb of foreign friends", "Nb of friends same country", "Activation Date", "Email Parent", "Parent Activated"]
        kids = Array.new
        all.each do |kid|
            if kid.user_role != "admin"
                k   = Array.new
                kid.name = kid.name rescue "No name"
                k << kid.name
                kid.surname = kid.surname rescue "No surname"
                k << kid.surname
                kid.email = kid.email rescue "No email"
                k << kid.email
                k << kid.age rescue "No age"
                if !kid.school.nil?
                    k << kid.school.name
                else
                    k << "No School"
                end
                if kid.courses.empty?
                    k << "No Courses"
                else
                    k << kid.courses.first.name
                end

                if !kid.native_languages.empty?
                    languages = Array.new
                    kid.native_languages.each do |lang|
                        languages << Language.find(lang).name
                    end
                    k << languages
                else
                    k << "No native language"
                end
                if !kid.practice_languages.empty?
                    languages = Array.new
                    kid.practice_languages.each do |lang|
                        languages << Language.find(lang).name
                    end
                    k << languages
                else
                    k << "No practise language"
                end

                k << kid.number_of_native_conversations rescue "0"
                k << kid.number_of_foreign_conversations rescue "0"
                k << kid.number_of_native_messages rescue "0"
                k << kid.number_of_foreign_messages rescue "0"
                k << kid.number_of_activity_posts rescue "0"
                k << kid.number_of_finished_closed_calls rescue "0"
                k << kid.number_of_missed_calls rescue "0"
                k << kid.avg_of_connections_week rescue "0"
                k << kid.number_of_foreign_friends rescue "0"
                k << kid.number_of_friends_same_country rescue "0"
                k << kid.confirmed_at.try(:strftime, "%d/%m/%Y") rescue "0"
                k << kid.tutor.email rescue "No parent email"
                k << kid.tutor.confirmed? rescue "No parent email"

                kids << k
            end
        end
        kids.each do |k|
            csv << k
        end
  end
end

但是在我的excel文件中，我得到了像JérÃ'me而不是Jérôme这样的名字。我试过了：

# encoding: utf-8

在我的观点上也尝试了每个领域

.force_encoding("UTF-8")

但我仍然有这个问题。我真的需要帮助。

提前致谢

Answer 1

CVS::generate了解选项:encoding（请参阅Ruby API）。

所以使用

format.xls { send_data @userxls.to_csv({col_sep: "\t", encoding: 'UTF-8'}) }

您也可以考虑分离表示和业务逻辑。我使用提供csv_builder等视图的user_report.csv.csvbuilder来定义csv输出。

cvs_builder使用实例变量@encoding来指定输出字符编码。

修改

看起来，就像你生成的csv已经用UTF-8编码了一样，但你读的就好像它是ISO-8859-1 aka。 LATIN-1。
您可能想尝试在LATIN-1中生成csv，因为excel在导入UTF-8 csv文件时出现问题。
根据Ruby或Rails版本，您必须使用ISO-8859-1而不是LATIN-1。
