With the following, where state defaults to enabled

I want a task like:

> `
> 
> - name: Enable plugins  
> rabbitmq\_plugin:  
> names: “**{{rabbitmq\_plugins.filter(p =\> p.state is not defined or p.state == ‘enabled’).map(\_.name).join(‘,’)}}**”  
> new\_only: yes  
> state: enabled  
> with\_items: rabbitmq\_plugins
> 
> notify:
> 
> - rabbitmq restart  
> `

Where of course the expression for ‘names’ is a dream. Its seems so painful to work with collections.  
I know can create a template and use a lookup, or create a filter plugin. But it should be easier.

Any nuggets out there from the ansible gurus?

So I ended up with

`  
{% for plugin in rabbitmq\_plugins if plugin.state is not defined or plugin.state == ‘enabled’ -%}  
{{plugin.name}}{% if not loop.last %}{{‘,’}}{% endif %}  
{% endfor %}

`

Not terrible, but…
