RAILS_ENV和轨道2.3.2

Question

i noted that in rails 2.3.2 there is no more option to set which rails environment you are using. So i cannot just set it anymore in environment.rb? There is any other way to set it?

Answer 1

RAILS_ENV=production rake db:migrate

What exactly are you trying to run? The rails generator? A rake task? Mongrel? I'm not sure this is actually a Rails issue.

Disclaimer: I haven't used 2.3.2, however.

Answer 2

im using rails 2.3.5 which should be similar to 2.3.2, and terry lorber is right,

RAILS_ENV=xyz is the exact way to lauch rails stuff with RAILS_ENV specifified from command line.

In this way, you can use rake, script/console script/runner script/server etc. in your different environments

Answer 3

Maybe you mean in config/environment.rb ?

I'm 90% sure you can just add the line there if you need it. And I'm wrong , see VP's comment below. (Tested and confirmed it)

Answer 4

If you wanna run an application in development,

ruby script/server

To run in production,

ruby script/server -e production

Answer 5

define in config/environments/production.rb or development.rb or whatever other modes you are running like stage.rb instead of writing/defining in config/environment.rb

I am using it and its serving my purpose. don't use the keyword RAILS_ENV (I haven't tried it) I am using it APP_MODE = "Production" In production environment file and APP_MODE = "Development" in development file.

then you can use this in your application to detect which mode you are in.

Hope, I answer the question

Answer 6

我认为这是一个命令行参数。
