I am using middleman (Ruby on Rails) with HAML.

I have code like this at the beginning of each page:

- if pageversion == "test"
   - domain = data.testvars.domain
   - action_url = data.testvars.openlocker_url
   - lockergroup = data.testvars.lockergroup

- else
  - domain = data.prdvars.domain
  - action_url = data.prdvars.openlocker_url
  - lockergroup = data.prdvars.lockergroup

but I want to know if it possible to do something like this:

domain = data.#{pageversion}vars.domain
…

so every time it parses #{pageversion} and uses the output to create either data.testvars.domain or data.prdvars.domain.

So I’d like to either specify which .yml file to use based on #{pageversion} or interpret the string before as part of the name of a variable to look in the correct file.

Any idea how to do this?

My current way of doing it involves a lot of duplicate code and trying to do it any other way has yielded errors only.
