How can I determine if my rails is in the development environment and not the test environment?
提问by spierepf
I have some code that needs to run only if the rails app is in the development environment (i.e. $ rails server) but not in the test environment (i.e. $ rake test).
我有一些代码需要在 rails 应用程序处于开发环境（即 $ rails server）而不是在测试环境（即 $ rake test）中时运行。
When I try
当我尝试
if Rails.env.development?
dont run me during testing
end
the code gets executed regardless of which environment I am in. I've even tried:
无论我在哪个环境中，代码都会被执行。我什至尝试过：
if Rails.env.development? and not Rails.env.test?
NO, REALLY, DONT RUN ME DURING TESTING
end
but no love.
但没有爱。
What should I be doing instead?
我应该怎么做？

It looks like you're calling it correctly. Perhaps the problem is that the environment is named differently somewhere. Try in the console:
看起来您正确地调用了它。也许问题在于环境在某处的命名不同。在控制台中尝试：
> Rails.env
=> "development"
> Rails.env.development?
=> true
> Rails.env.test?
=> false
...to confirm that the environment is what you think it is.
...确认环境是您认为的那样。
