[chef] Re: Re: Re: how do I share common functions between templates

[John Dyer < >]

Bryan,

   Personally when I have more complicated logic in a template I'll factor that out into a library method, which I then call directly in the template...   Only draw back here is that the node data isnt available in the Library, so I have to pass that into the method...

......

<networkAccessPoints>

<%= Prism.build_network_access_point(node) %>

</networkAccessPoints>

.....

hope that helps

-John

Surely, we can all agree to call these something more chef-fy...a "buffet" or "serving dish".

Partials are a new feature in chef (just merged to master, in fact: https://github.com/opscode/chef/pull/498)

For now, I'm not sure there is a good solution. You can possibly use ERB to evaluate the a subtemplate and pass that into a template via variables.
