Question

我是action_mailer的新手，我不知道会出现什么问题。过去12个小时我一直在圈子里。它可能是一个宝石依赖，它可能是我做错了。请帮忙！

邮件在我的本地环境中工作，但我无法推送到heroku。我一直收到这个错误：

-----> Preparing app for Rails asset pipeline
   Running: rake assets:precompile
   rake aborted!
   NoMethodError: undefined method `action_mailer' for #<Rails::Application:
:Configuration:0x00000002fad208>

在将版本添加到GEM文件后编辑新错误

Running: rake assets:precompile

我正在尝试将Mandrill用于我的SMTP服务器。我已经安装并正确配置了heroku插件（据我所知）。我遵循了这个：https://devcenter.heroku.com/articles/mandrill

user_mailer文件：

class UserMailer < ActionMailer::Base
  default from: "info@myflix.com"

  def send_welcome_email(user)
      @user = user
  mail(to: @user.email, subject: "Welcome to Myflix!")
  end
end

生产环境

Myflix::Application.configure do

 config.action_mailer.delivery_method = :smtp
 config.action_mailer.smtp_settings = {
   :address              => 'smtp.mandrillapp.com',
   :port                 => 587,
   :user_name            => ENV['MANDRILL_USERNAME'],
   :password             => ENV['MANDRILL_APIKEY'], # SMTP password is any valid API key
   :domain               => 'heroku.com', # your domain to identify your server when  connecting
   :authentication       => 'plain' # Mandrill supports 'plain' or 'login'
 }

 config.cache_classes = true
 config.eager_load = true
 config.consider_all_requests_local       = false
 config.action_controller.perform_caching = true

 config.serve_static_assets = false

 config.assets.compress = true
 config.assets.js_compressor = :uglifier

 config.assets.compile = false

 config.assets.digest = true

 config.i18n.fallbacks = true

 config.active_support.deprecation = :notify
end

的Gemfile：

gem 'coffee-rails'
gem 'rails', '4.0.0'

group :development, :test do

end

Answer 1

指定您在Gemfile

中使用的Rails版本

例如，如果您使用Rails 3.2.13：

gem 'rails', '3.2.13'

或者如果你使用Rails 4

gem 'rails', '4.0.0' `

运行bundle install

希望有效。

Answer 2

这是一个依赖性问题。感谢@Abednego，我在我的宝石文件中添加了rails版本，当我得到一个新的错误时，我研究了这个并发现它是sass-rails的依赖问题。新的gemfile如下：

source 'https://rubygems.org'
ruby '1.9.3'

gem 'bootstrap-sass'
gem 'coffee-rails'
gem 'rails', '4.0.0'
gem 'haml-rails'
gem 'sass-rails', "4.0.2"
gem 'uglifier'
gem 'jquery-rails'
gem 'bootstrap_form'
gem 'bcrypt-ruby', '~> 3.0.0'
gem 'fabrication'
gem 'faker'


group :development do
  gem 'sqlite3'
  gem 'pry'
  gem 'pry-nav'
  gem 'thin'
  gem 'better_errors'
  gem 'binding_of_caller'
  gem 'letter_opener'
end

group :development, :test do
    gem 'rspec-rails'
end

group :test do
    gem 'shoulda-matchers'
  gem 'capybara'
  gem 'launchy'
end

group :production do
  gem 'pg'
  gem 'rails_12factor'
end
