私は最近、ファイルをアップロードしているように見えるRoRプロジェクトにインポートオプションを追加し、このファイルをdbに正常に保存しましたが、新しいユーザーを作成して保存しようとすると、次のエラーが発生します

これは、インポートコントローラーにあるコードです

    params = Hash.new
    params[:user] = Hash.new
    params[:user]["email"] = line[0]
    params[:user]["gender"] = "male"

    params[:user]["first_name"] = line[1]
    params[:user]["last_name"] = line[3]
    user = User.new(params[:user])
    user.save
  end


def proc_csv
    @import = Import.find(params[:id])
    lines = parse_csv_file(@import.csv.path)
    lines.shift #comment this line out if your CSV file doesn't contain a header row
    if lines.size > 0
      @import.processed = lines.size
      lines.each do |line|
        case @import.datatype
          when "releases"
            new_user(line)
            flash[:notice] = "Saving data processing was successful."
        end
      end
      @import.save
      flash[:notice] = "CSV data processing was successful."
      redirect_to :action => "show", :id => @import.id
    else
      flash[:error] = "CSV data processing failed."
      render :action => "show", :id => @import.id
    end
  end

コード スニペットとログ出力から、検証の問題が原因でユーザーが保存されていないようです。通常、このような問題が発生した場合は、Rails コンソールにドロップして、コードが実行しようとしていることがコンソールでも機能するかどうかを確認します。コンソールで動作する場合、コードは動作するはずです。

これを試して

$ rails c --sandbox

> params = {
           :user => {
                   :gender => "male",
                :last_name => "paul",
                 :password => "abc231",
               :first_name => "mcguane",
                    :email => "paul.mcguane1@westnet.com.au"
           }
         }

> user = User.new(params[:user])
> user.valid?
> user.errors.full_messages

そうすれば、本当にユーザー検証が問題の原因であるかどうかを特定できます。それはまったく別のものかもしれません。ユーザーモデルコードを投稿すると、それも役立ちます。

linesまた、イテレータ内でフラッシュ通知を設定していることにも気付きました。行を反復するたびに上書きするだけです。
