Question

我遇到了创建操作的问题。传递验证时，记录将在数据库中保存两次。有时会有更多重复的记录。

IndividualTrainingController

  def create
    @individual_training = IndividualTraining.new(individual_training_params)
    Stripe.api_key = ENV['STRIPE_SECRET_KEY']
    token = params[:stripeToken]
    if @individual_training.valid?
      begin
        charge = Stripe::Charge.create(
          amount: (@individual_training.training_cost.cost * 100).floor,
          currency: 'pln',
          card: token
        )

        if charge && @individual_training.save
          redirect_to show_backend_individual_trainings_path(@client), notice: 'Pomyślnie dodano.'
        else
          render :new
        end
      rescue Stripe::CardError => e
        flash[:danger] = e.message
        render :new
      end
    else
      render :new
    end
  end

结果：

你知道这种情况的原因是什么吗？如果您想了解更多信息，请写下评论。
