How to set rails_env for a script or batch file
I put my batch file in lib folder and use rails db configuration, active-record like this.
require "#{File.dirname(__FILE__)}/../config/environment.rb"
class Batch
def hello
Message.new do |t|
t.title = "hello"
t.save
end
end
end
batch = Batch.new
batch.hello
when excute batch
ruby lib/batch.rb
in development environment it's ok
but pro开发者_JAVA百科duction environment still save development database...
how do i set rails_env batch.rb like this
ruby lib/batch.rb RAILS_ENV=production
To initialise the Rails environment, instead of putting
require "#{File.dirname(__FILE__)}/../config/environment.rb"
launch your batch file using script/runner
and specify the environment with the -e
option
e.g.
script/runner -e production lib/batch.rb
I think the above is The Rails Way of writing and executing a script that needs the Rails framework initialised in order to work. The alternative, as neutrino says, is to prefix the command with RAILS_ENV=value e.g.
$ RAILS_ENV=production lib/batch.rb
This is a standard shell feature to set an environment variable prior to executing a command.
Just FYI without script/runner :
RAILS_ENV=production ruby lib/batch.rb
