Is it possible for templates to have multiple if and/or statements.

It seems to work ok for 2, however any more than this and it does not seem to work correctly.

Details: Works for

<% if environment == "qa" and group == "test" %>

Does not work for

<% if environment == "qa" or environment == "dev" and group == "test" or group == "test2" %>

I assume you mean the 2nd expression doesn't evaluate to true when expected, rather than throws a syntax error? What are the values of environment and group when you ...(more)

I'd like to see your Puppet code, and the values that are being used in the template, please.

Hi, I am looking for it to be either environment qa/dev and then if the group matches either test or test2 for those 2 environments then the action is performed.

The code you're using should work correctly, tested with Ruby 1.8.7 and 1.9.3 in a script like the one below. However you may want to explicitly set the order in which it's evaluated in case your real code doesn't match the example. Here's a simple Ruby script, erb is just Ruby, to test with.

#!/usr/bin/env ruby

environment = 'dev'
group = 'test'

puts "My values are #{environment} #{group}"

if ((environment == 'qa' or environment == 'dev') and (group == 'test' or group == 'test2'))
  puts "I matched on both #{environment} #{group}"

# this is equivalent to ...

Does Ruby evaluation left to right instead of *and* before *or*?

Made some edits to my answer to clarify. It does do and before at least in my testing. I think using parens in the real code might help track it down.

Hi, I have retested with your addition of the brackets and this now seems to work as intended. Thanks very much for the response!!
