puppet defined type and creating multiple templates from 1 .erb file

Question

I need to find a solution to this problem that I've come across.

I have a hash (it's supposed to be overriden as a smart class parameter later on) that I am iterating trough in my template.erb to generate multiple File resources that I have defined using an array. I want the iteration to stop after it's trough the first set of key value pairs and then start writing to the next file.

I'll show an example to make things clearer.

#### init.pp ####
class testing ( 
$nameid = ['alex','ben'],
$game_code = {
    alex_super_mario => {
            "type"     => "1",
            "characters" => {
                            "bowser" => "123",
                            "luigi" => "456",
                            "princess" => "789" }
    },
    ben_mega_man => {
            "type" => "2",
            "characters" => {
                            "something" => "111213",
                            "else" => "131415",
                            "lastone" => "161718" }
    },
 }
) {

define testing(
$base_path = '/var/tmp/testing',
){
file  {"${base_path}/${name}_file.xml":
  owner   => 'root',
  group   => 'root',
  ensure  => 'file',
  mode    => '0644',
  content => template("testing/template.xml.erb"),
 }
}
testing { [$nameid]: }
}

### template file ### template.xml.erb

  <% @nameid.each do |username| %>
<UserName><%= username %></UserName>
<% end %>
<games>
<% @game_code.sort.map do |hero, value| %>
<% value.sort.map do |game,code| %>
         <% if game == "characters" %>
                <% code.each do |k, v| %>
    <game>
        <type><%= value['type'] %></type>
        <gameid><%= v %></gameid>
        <extcharacters>
            <char>/var/tmp/<%= k %></path>
        </extcharacters>
    </game>
            <% end %>
    <% end %>
 <% end %>
<% end %>
</games>

# this generates two files from my array $nameid = ['alex','ben'] as expected.

Notice: /Stage[main]/Testing/Testing::Testing[ben]/File[**/var/tmp/testing/ben_file.xml**]/ensure:     defined content as '{md5}21af03b1dd7427d17c2460bae323bc24'
Notice: /Stage[main]/Testing/Testing::Testing[alex]/File[**/var/tmp/testing/alex_file.xml**]/ensure:     defined content as '{md5}21af03b1dd7427d17c2460bae323bc24'
Notice: Finished catalog run in 0.34 seconds

However looking inside these files I get two identical files with the output for both "alex_super_mario" and "ben_mega_man" key from my hash $game_code:

The expected output I want to achieve is basically to have the first set of iterations that is done for "alex_super_mario" => { .... to go inside the alex_file.xml together with the alex username.

and the ben_mega_man stuff go inside the ben file.

Is this possible?

    <UserName>alex</UserName>  <--- ## this should go into the alex_file.xml

<UserName>ben</UserName> <--- ## this should go into the ben_file.xml ##

<games>




    <game>                       ## <-- this should go to the ben_file.xml
        <type>2</type>
        <gameid>111213</gameid>
        <extcharacters>
            <char>/var/tmp/something</path>
        </extcharacters>
    </game>

    <game>
        <type>2</type>
        <gameid>161718</gameid>
        <extcharacters>
            <char>/var/tmp/lastone</path>
        </extcharacters>
    </game>

    <game>
        <type>2</type>
        <gameid>131415</gameid>
        <extcharacters>
            <char>/var/tmp/else</path>
        </extcharacters>
    </game>




    <game>                  ### <------ these should go into the alex_file.xml
        <type>1</type>
        <gameid>123</gameid>
        <extcharacters>
            <char>/var/tmp/bowser</path>
        </extcharacters>
    </game>

    <game>
        <type>1</type>
        <gameid>789</gameid>
        <extcharacters>
            <char>/var/tmp/princess</path>
        </extcharacters>
    </game>

    <game>
        <type>1</type>
        <gameid>456</gameid>
        <extcharacters>
            <char>/var/tmp/luigi</path>
        </extcharacters>
    </game>

Your template explicitly loops over nameid and then over all keys in game_code, so of course each generated file is going to have all the data in it. Perhaps something like this would do:

<UserName><%= @name %></UserName>
<games>
<% @game_code.sort.map do |hero, value|
if (somecondition)
value.sort.map do |game,code| 
         <if game == "characters" 
                 code.each do |k, v| %>
    <game>
        <type><%= value['type'] %></type>
        <gameid><%= v %></gameid>
        <extcharacters>
            <char>/var/tmp/<%= k %></path>
        </extcharacters>
    </game>
            <% end 
     end 
  end 
end
end %>
</games>

where "somecondition" is however you want to decide if the current 'value' hash is the one that matches your current hero name (it's hard to tell how you want to do that, given that they keys in game_code don't match the strings in nameid)

You are right! I will have to change the keys in game_code to match the string in nameid and set that if condition. if ( @name == hero) maybe ? — ThreeTwo, Feb 22 '15 at 08:17
