How to control when notify gets triggered by i.e. command

[Jonas Rottmann]

Hi,

I have for an example an task which enables modules in apache2 in debian with the command a2enmod.

So I have:

- name: Debian | Apache | Enable Basic Mods

  command: a2enmod {{ item }}

  with_items:

    - rewrite

    - ssl

  when: "ansible_os_family == 'Debian'"

  tags: apache

  notify:

    - restart apache2

Now I don't wan't to get apache restarted every single time, only if it really enabled an module. I can handle such a task as failed with:

register: command_result
failed_when: "'Enabling module' in command_result.stderr"

I would need that but for success not for failing.

Is this possible?

thanks

so you have changed_when, which will control notify the handler, also
you have the apache2_module which might make this much easier.

Thanks, the changed_when was what I was looking for.
