Rails:配置邮件程序时未初始化的常量库(NameError)

Question

我将environment.rb文件配置如下：

# Load the Rails application.
require File.expand_path('../application', __FILE__)

# Initialize the Rails application.
Rails.application.initialize!

rapp::Application.configure do
    config.action_mailer.delivery_method = :smtp

    config.action_mailer.smtp_settings = {
        address:        "smtp.gmail.com",
        port:           587,
        domain:         "gmail.com",
        authentication:     :login,         # will send password Base64 encoded
        user_name:      "myadress",
        password:       "mypass",
        enable_starttls_auto:   true
    }
end

但是，当我试图生成这样的mailer类时：

rails generate mailer MailNotifier template1 template2 template3

我发现了一个错误：

/home/usr/.../rapp/config/environment.rb:7:in `<top (required)>': undefined local variable or method `rapp' for main:Object (NameError)

from bin/rails:4:in `require'
from bin/rails:4:in `<main>'

有人能帮忙解决这个问题吗？

将action_mailer设置为：-

http://stackoverflow.com/questions/23300150/actionmailer-not-working-when-i-change-gmail-password/23300459#23300459

从environment.rb文件中删除

rapp::Application.configure do
    config.action_mailer.delivery_method = :smtp

    config.action_mailer.smtp_settings = {
        address:        "smtp.gmail.com",
        port:           587,
        domain:         "gmail.com",
        authentication:     :login,         # will send password Base64 encoded
        user_name:      "myadress",
        password:       "mypass",
        enable_starttls_auto:   true
    }
end

那就试试：-

rails generate mailer MailNotifier template1 template2 template3
