Rails - Use ENV variable in yml file

This is myfile.yml

this_is_key:
  - [<%= ENV['MY_KEY_NAME'] %>, 1]

It will return the error syntax, can not parse file.Now, i change like this:

this_is_key:
  - [my_key_here, 1]

No errors occurred. Somebody can tell me, how can i pass ENV variable in my file?

You can do it only if you parse the resulting yml file as an erb template:

YAML.load(ERB.new(File.read("myfile.yml")).result)

result method passes the current binding into template and renders the file according to the variables in the scope.

Here's an article about such experiments.
