是否可以检查 Rails 环境中正在运行的 rake 任务？

我可以在 Rails 初始化程序中利用环境变量来确定 rake 任务是否正在执行吗？就像 -- rake db:migrate db:seed

我有一堆初始化程序，对于大多数 rake 任务可以跳过：

不要加载 spring （这是一个 jruby 项目）
不要加载审计观察者这会破坏迁移

更新：

我稍后可能会后悔——但以下内容似乎有效——

在我的 application.rb 中——添加了以下内容：

config.is_rake = (File.basename($0) == 'rake')

检查该值

config.active_record.observers = :audit_observer unless config.is_rake

然后我稍后会在春天的其他地方初始化器

SPRING_CONTEXT = org.springframework.context.support.FileSystemXmlApplicationContext.new(SPRING_XML_CONFIG_FILES) unless Rails.application.config.is_rake

基于答案在这里找到

原文

Is there an environment variable I could leverage in my rails initializers to determine if a rake task is executing ? Like -- rake db:migrate db:seed

I have a bunch of initializers that could be skipped for most rake tasks:

Don't load spring (it's a jruby project)
Don't load the audit observer that breaks the migration

Update:

I'm probably going to regret this later -- but the following seems to work --

In my application.rb -- have added the following:

config.is_rake = (File.basename($0) == 'rake')

Then I am checking for the value later on

config.active_record.observers = :audit_observer unless config.is_rake

Elsewhere in my spring initializer

SPRING_CONTEXT = org.springframework.context.support.FileSystemXmlApplicationContext.new(SPRING_XML_CONFIG_FILES) unless Rails.application.config.is_rake
