Question

我有一个在开发中完美运行的应用程序，一旦部署到Heroku，它的大多数工作正常。邮寄到/users时收到错误，由UsersController#create处理。我似乎无法追查实际问题是什么。

我的UsersController：

    class UsersController < InheritedResources::Base
      actions :new, :edit, :update
      before_filter :require_user, only: [:show]

      def create
        @user = User.new(user_params)
        result = UserSignup.new(@user).sign_up(params[:stripeToken], params[:invitation_token])
        if result.successful?
          flash[:success] = "Thank you for registering! Please sign in."
          redirect_to sign_in_path
        else
          flash[:error] = result.error_message
          render :new
        end
      end  
    ...
    end

在Heroku上，我可以填写注册表并提交。页面/users上显示错误“我们很抱歉，但出现了问题”，因此当Heroku在我的本地环境中时，创建功能显然不成功。

请原谅任何新手疏忽。我很感激任何提示。谢谢。

UserSignup.rb：

    class UserSignup

      attr_reader :error_message

      def initialize(user)
        @user = user
      end

      def sign_up(stripe_token, invitation_token)
        if @user.valid?
          customer = StripeWrapper::Customer.create(
            :user => @user,
            :amount => 999, # amount in cents  currency is hardcoded in wrapper
            :card => stripe_token,
            :description => "Subscribtion charge for #{@user.email}"
          )
          if customer.successful?
            @user.customer_token = customer.customer_token
            @user.save
            handle_invitation(invitation_token)
            AppMailer.send_welcome_email(@user).deliver
            @status = :success
            self
          else
            @status = :failed
            @error_message = customer.error_message
            self
          end
        else
          @status = :failed
          @error_message = "Invalid user information. Please check your info."
          self
        end
      end

      def successful?
        @status == :success
      end

      private

      def handle_invitation(invitation_token)
        if invitation_token.present?
          invitation = Invitation.where(token: invitation_token).first
          @user.follow(invitation.inviter)
          invitation.inviter.follow(@user)
          invitation.update_column(:token, nil)
        end
      end
    end

评论太长了 -

正如@Mandeep在评论中所述，问题可能与UserSignup.new行有关;问题是为什么

我认为有很多方面需要关注：

-

<强>结果

您的行如下：

result = UserSignup.new(@user).sign_up(params[:stripeToken], params[:invitation_token])

这里的问题是您正在尝试使用原始对象构建另一个（看似无关的）对象。这里的核心问题是这条线看起来很简单（抱歉缺乏科学答案）。我将重点关注您的User和UserSignup对象之间的关联，特别是使用after_create回调来填充UserSignup功能：

#app/controllers/users_controller.rb
Class UsersController < InheritedResources::Base
   ...
   def user_params
      params.require(:user).permit(:your, :user, :params).merge(stripe_token: params[:stripeToken], invitation_token: params[:invitation_token])
   end
end

#app/models/user.rb
Class User < ActiveRecord::Base
   attr_accessor :stripe_token, :invitation_token

   before_create :create_user_signup
   after_create  :send_welcome_email

   private

   def create_user_signup
      result = UserSignup.new(self).sign_up(stripe_token, invitation_token)
      if result.successful?
         @user.customer_token = customer.customer_token
         # you might need a "return" here
      else
        errors.add("Stripe Error")
        # likewise, you might need "return false" here
      end
   end

   def send_welcome_email
      AppMailer.send_welcome_email(self).deliver
   end
end

#app/models/user_signup.rb
Class UserSignup
   def sign_up(stripe_token, invitation_token)
      return StripeWrapper::Customer.create(
        :user => @user,
        :amount => 999, # amount in cents  currency is hardcoded in wrapper
        :card => stripe_token,
        :description => "Subscription charge for #{@user.email}"
      )
   end
end

虽然这绝不是经过验证的代码，但我试图为您做的是模块化你的电话。您遇到的一个大问题是您在User

中调用UserSignup模型方法

为了与OOP原则保持一致，您希望确保使用相应对象的相应方法

-

<强>条纹

其次，您要将数据提交到Stripe

这里的问题可能源于几个问题：

您的Stripe凭据可能无法在Heroku上使用

您的UserSignup型号可能没有向Stripe发送正确的数据

您确定Stripe是否在production环境中工作？

人们对Heroku的核心问题之一就是没有设置environment variables。由于STRIPE需要某些API密钥才能运行，因此您需要确保在后端设置它们

为此，您可以使用Heroku的CLI（Heroku Toolbelt），如下所示：

$ heroku config:set STRIPE_SECRET_KEY=your_secret_key

创建用户时Heroku路由错误
