ruby-on-rails - ActionMailer：默认发件人：地址？

Question

谷歌搜索无济于事。也没有在 API 中找到任何东西。我期待某种类方法或配置选项来设置它......

所以，而不是打电话

from "my@email.com"

对于每种方法，它都可以自动调用。

Answer 1

Rails 3

config/environments/development.rb:

ActionMailer::Base.default :from => 'default@development-server.com'

config/environments/production.rb:

ActionMailer::Base.default :from => 'default@production-server.com'

You can also set this per mailer:

class MyMailer < ActionMailer::Base
  default :from => 'default@myapp.com'
end

Rails 2

This is not supported by default. But you can achieve this functionality by using the action_mailer_callbacks plugin. Essentially this plugin allows you to add before and after filters for the deliver method.

class FooMailer < ActionMailer::Base
  before_deliver do |mail|
    mail.from = "abc@xyz.com"
  end

end

Reference:

1) Article discussing the plugin.

OR

You can monkey patch the from method of ActionMailer::Base.

Add the code below to your config\initializers\mail.rb

class ActionMailer::Base
  class_inheritable_hash :default
  def from_with_default(input=nil)
    return from_without_default(input) || default[:from] if input.nil?
    from_without_default(input)
  end
  alias_method_chain :from, :default
end

Now you can configure your default value as follows:

config/environments/development.rb:

ActionMailer::Base.default = {:from => 'default@development-server.com'}

config/environments/production.rb:

ActionMailer::Base.default = {:from => 'default@production-server.com'}

You can also set this per mailer:

class MyMailer < ActionMailer::Base
  self.default = {:from => 'default@myapp.com'}
end

Answer 2

在 Rails 4 中，您可以在您的环境中进行设置：

config.action_mailer.default_options = {
  :from => "foo@bar.com"
}

Answer 3

在 Rails 3 中：

配置/环境/development.rb：

ActionMailer::Base.default :from => 'default@development-server.com'

配置/环境/production.rb：

ActionMailer::Base.default :from => 'default@production-server.com'

Answer 4

我采用了 KandadaBoggu 建议的猴子修补方法。但是，它在 Rails 2.3.8 中不能正常工作。你不能覆盖默认值。但是，这有效：

def from_with_default(input=nil)
  return instance_variable_set("@from", input) unless input.nil?
  from_without_default || FROM_EMAIL
end
alias_method_chain :from, :default

Answer 5

红宝石 5 & 6

config/environments/$RAILS_ENV.rb
config.action_mailer.default_options = {来自：'no-reply@example.com'}

Answer 6

.. rails-6 有变化吗？

config.action_mailer.default_options = { from: 'noreply@xxx.xx' }
