You seem to have a misapprehension here. See below.

I would write it using a selector, like this:
file { "somefile" :
ensure => ${hasfile} ? {
'true' => present,
default => absent
},
source => "puppet:///somefile",
owner => "root",
}
Others' examples of using an 'if' statement outside the resource are
also fine, but where the desired conditional effect is so localized, I
prefer to localize the conditional itself.
