    <p>Sadly, even if you go about and use a custom "define" to iterate over an array upon splitting your custom fact on a comma, the result will be rather not what you expect and not even close to a "for each" loop -- aside of causing you a headache, probably.</p> <p>Said that, I am not sure if this is what you want to achieve, but have a look at this approach:</p> <pre><code>$fact = '1.1.1.1,2.2.2.2,3.3.3.3' $servers = split($::fact, ',') $count = size($servers) $names = bracket_expansion("host[01-${count}].address") file { '/tmp/test.txt': content =&gt; inline_template('&lt;%= @servers.each_with_index.map {|v,i| "#{v}\t\t#{@names[i]}\n" } %&gt;'), ensure =&gt; present } </code></pre> <p>What we have there are two custom functions: size() and bracket_expansion(); which we then use values that they provide inside a hack that leverages the inline_template() function to render content of the file utilising parallel access to two arrays -- one with IP addresses from your fact and one with host names that should follow.</p> <p>The result is a follows:</p> <pre><code>matti@acrux ~ $ cat | puppet apply $fact = '1.1.1.1,2.2.2.2,3.3.3.3' $servers = split($::fact, ',') $count = size($servers) $names = bracket_expansion("host[01-${count}].address") file { '/tmp/test.txt': content =&gt; inline_template('&lt;%= @servers.each_with_index.map {|v,i| "#{v}\t\t#{@names[i]}\n" } %&gt;'), ensure =&gt; present } notice: /Stage[main]//File[/tmp/test.txt]/ensure: created notice: Finished catalog run in 0.07 seconds matti@acrux ~ $ cat /tmp/test.txt 1.1.1.1 host01.address 2.2.2.2 host02.address 3.3.3.3 host03.address matti@acrux ~ $ </code></pre> <p>Both size() and bracket_expansion() functions can be found here:</p> <p><a href="https://github.com/kwilczynski/puppet-functions/tree/master/lib/puppet/parser/functions/">https://github.com/kwilczynski/puppet-functions/tree/master/lib/puppet/parser/functions/</a></p> <p>I hope this helps a little :-)</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
