Re: [ansible-project] for loop in template gives error undefined variables: list object has no element

[Brian Coca]

you seem to be trying to use the jinja2 implicit loop.index but you
are branching it off of the server dictionary
I believe you want:
Server{{ usenet_servers[server] + '.' + loop.index }}.Level={{
usenet_servers[server].level }}

I believe you need to make 2 changes:

loop.index instead of usenet_servers[server].loop.index

And just use server instead usenet_servers[server] everywhere else. server isn't the index, it is the actual hash/dict.

Hi all

Can anyone help me with do a loop in a template?

bcoca helped me earlier on IRC and I think I'm a bit closer than I was before! =]

(1) variables (layout copied from http://www.yaml.org/start.html)

usenet_servers:
    - server: astraweb
      level: 0
      host: ssl-eu.astraweb.com
      port: 563
      username: me
      password: mypass
      join_group: yes
      connections: 2
    - server: newsgroupdirect
      level: 1
      host: news-eu-ssl.newsgroupdirect.com
      port: 563
      username: me
      password: mypass
      join_group: yes
      connections: 3
    - server: newsgroupdirect
      level: 1
      host: news.tweaknews.eu
      port: 563
      username: me
      password: mypass
      join_group: yes
      connections: 10

(2) task

- name: create nzbget conf file
  template:
    src=nzbget.conf.j2
    dest=/etc/nzbget.conf
    mode=660
    owner=root
    group=library

(3) loop in template nzbget.conf.j2

{% for server in usenet_servers %}
Server{{ usenet_servers[server].loop.index }}.Level={{ usenet_servers[server].level }}
Server{{ usenet_servers[server].loop.index }}.Host={{ usenet_servers[server].host }}
Server{{ usenet_servers[server].loop.index }}.Port={{ usenet_servers[server].port }}
Server{{ usenet_servers[server].loop.index }}.Username={{ usenet_servers[server].username }}
Server{{ usenet_servers[server].loop.index }}.Password={{ usenet_servers[server].password }}
Server{{ usenet_servers[server].loop.index }}.JoinGroup={{ usenet_servers[server].join_group }}
Server{{ usenet_servers[server].loop.index }}.Connections= {{ usenet_servers[server].connections }}


{% endfor %}

(4) desired output from loop

Server1.Level=0
Server1.Host=ssl-eu.astraweb.com
Server1.Port=563
Server1.Username=me
Server1.Password=mypass
Server1.JoinGroup=yes

Server2.Host=news-eu-ssl.newsgroupdirect.com
Server2.Port=563
Server2.Username=me
Server2.Password=mypass
Server2.JoinGroup=yes
Server2.Connections=3

Server3.Level=1
Server3.Host=news.tweaknews.eu
Server3.Port=563
Server3.Username=me
Server3.Password=mypass
Server3.JoinGroup=yes
Server3.Connections=10
