Puppet users - Dec 2013 - Pass variable to class from hiera puppetlabs-apache

Hi,

I am cleaning my manifest by moving things to hiera yaml config file.

For the https://github.com/puppetlabs/puppetlabs-apache I need to 
pass mpm_module variable as false like:

class { ''apache'':
  mpm_module => false
}

But I can''t figure out how to do this in hiera yaml file. I include
classes
using hiera_include(''classes'').

I tried 

classes:
     - apache
     - apache::mpm_module: false
     - apache::mod::prefork
     - apache::mod::php
     - apache::mod::rewrite
     - apache::mod::ssl

But I get error

Error: undefined method `downcase'' for
{"apache::mpm_module"=>false}:Hash
at /tmp/vagrant-puppet/manifests/site.pp:13 on node precise64.asus

Please advise how properly pass variables to classes in yaml files?

Thank you a lot

Yuriy

The classes indicator/variable/key (whatever it''s officially called) is
only for classes. 
Then in the appropriate yaml file, specify:
apache::mpm_module: false
or whatever. It''s that easy.

So your file should look like:

classes:
     - apache

apache::mpm_module: false
apache::mod::prefork: true
apache::mod::php: this
apache::mod::rewrite: that
apache::mod::ssl: "the other"

Exactly so.  The latter part is an exercise of Puppet 3''s automatic
data
binding feature, and it is applicable to any of the available mechanisms by 
which you can declare classes, either directly or indirectly.  Class 
parameter values defined that way in your hiera hierarchy will be effective 
whether you ''include'', ''require'', or
''contain'' (coming soon) a class, or if
you declare it via hiera_include() or another function.  They will be 
effective also if you use parameterized-style class declarations, except 
that parameter values declared explicitly in such a declaration override 
hiera data.
