ruby ActionMailer uninitialized constant ActionMailer(NameError)

今天用了学习了点ruby的使用actionmailer发送电子邮件，看着教材写的，没想到还报错

 

首先要配置actionmailer的参数，指定邮件的发送方式，邮件服务器的地址以及账户信息等（就是这里报错了）

我之前的config/envirenment.rb是这样修改的

RAILS_GEM_VERSION = '2.3.2' unless defined? RAILS_GEM_VERSION

# Bootstrap the Rails environment, frameworks, and default configuration
require File.join(File.dirname(__FILE__), 'boot')

Rails::Initializer.run do |config|
 
  config.time_zone = 'UTC'
  ActionMailer::Base.delivery_method = :smtp
  ActionMailer::Base.default_charset = "utf-8"
  ActionMailer::Base.raise_delivery_errors = true
  ActionMailer::Base.smtp_settings={
    :address =>"smtp.***.com",
    :port => **,
    :domain =>"***.com",
    :user_name =>"***",
    :password =>"***",
    :authentication => :login
  }
end

 

当执行：ruby script\generate mailer WebMailer web时

错误如下：

D:/rubytest/rails_app/mailers/config/environment.rb:41: uninitialized constant A
ctionMailer (NameError)
        from D:/ruby/lib/ruby/gems/1.8/gems/rails-2.3.2/lib/initializer.rb:111:i

        from D:/ruby/lib/ruby/gems/1.8/gems/rails-2.3.2/lib/commands/generate.rb

        from D:/ruby/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:31:in `re
quire'
        from script/generate:3

 

解决方法：

 

要把你的配置参数放到最下面，Rails::Initializer.run do |config|这个块的外面，

RAILS_GEM_VERSION = '2.3.2' unless defined? RAILS_GEM_VERSION

# Bootstrap the Rails environment, frameworks, and default configuration
require File.join(File.dirname(__FILE__), 'boot')

Rails::Initializer.run do |config|
 
  config.time_zone = 'UTC'
 
end
 ActionMailer::Base.delivery_method = :smtp
  ActionMailer::Base.default_charset = "utf-8"
  ActionMailer::Base.raise_delivery_errors = true
  ActionMailer::Base.smtp_settings={
    :address =>"smtp.wlotx.com",
    :port => 25,
    :domain =>"wlotx.com",
    :user_name =>"fengcx",
    :password =>"abc123",
    :authentication => :login
  }

这样就可以了，呵呵！
