active_merchant 的配置设置与 Rails 3 应用程序兼容

Question

我正在关注 http://railscasts.com/episodes/145-integrating-active-merchant

如何设置配置设置以与 Rails 3 应用程序兼容。

我尝试将以下内容放入 config/initializers/active_merchant.rb 中，

if Rails.env == 'development'
  config.after_initialize do
    ActiveMerchant::Billing::Base.mode = :test
    ::GATEWAY = ActiveMerchant::Billing::PaypalGateway.new(
      :login     => 'seller12341234zxcv.foobar.com',
      :password  => 'pasword',
      :signature => 'abc123'
    )
  end
elsif Rails.env == 'test'
  config.after_initialize do
    ActiveMerchant::Billing::Base.mode = :test
    ::GATEWAY = ActiveMerchant::Billing::BogusGateway.new
  end
elsif Rails.env == 'production'
  config.after_initialize do
    ActiveMerchant::Billing::Base.mode = :test
    ::GATEWAY = ActiveMerchant::Billing::PaypalGateway.new(
      :login     => 'seller12341234zxcv.foobar.com',
      :password  => 'pasword',
      :signature => 'abc123'
    )
  end
end

以下内容会出现错误：

config/initializers/active_merchant.rb:2:in `<top (required)>': undefined local variable or method `config' for main:Object (NameError)

Answer 1

看起来你只需要摆脱 config.after_initialize do 块 - 之后应该可以正常初始化。

Answer 2

您可以将此代码放入您的环境文件中，即 config/environments/development.rb, production.rb 等只需使用

config.after_initialize do
  ActiveMerchant::Billing::Base.mode = :test
  ::GATEWAY = ActiveMerchant::Billing::PaypalGateway.new(
   :login     => 'seller12341234zxcv.foobar.com',
   :password  => 'pasword',
   :signature => 'abc123'
  )
end

Answer 3

您需要将 config.after_initialize 更改为 ApplicationName::Application.config.after_initialize ，它应该可以正常工作。
