在rake任务中获取服务器url

Question

Is there any way I can get the url of the application inside a rake task? I'm running heroku, so maybe there is a way I can get hold of the appname?

Answer 1

I was able to do the following in my Rakefile:

task(:foo => :environment) do
  puts ENV['APP_NAME']
end

and it successfully returned Heroku's application name, my_foo_app. when I ran the command:

heroku rake foo --app my_foo_app

Answer 2

You can just set a config variable with the app URL using

heroku config:add APP_URL=http://myapp.com

Then you can get the value inside your rake task (or anywhere in your app) using ENV['APP_URL']
