producing json compliant output from jinja template

[Rajul Vora]

Hello Salties:

how do I produce double-quoted string list out of jinja that will be JSON compatible?

foo-template:

{

  "foo": {{ pillar['foo'] }}

}

salt/pillar/foo.sls:

foo:

  - 10.1.1.1

  - 10.2.2.2

This when rendered produces single-quoted strings which is not JSON:

{

  "foo": ['10.1.1.1', '10.2.2.2']

}

How can we produce double-quoted strings?

Thanks,

Rajul

Hi Rajul,

If you're using jinja and if you know that your pillar variables will
never contain single quotes, you could do:

{
"foo": {{ pillar['foo']|replace("'", '"') }}
}

or

{
"foo": ["{{ pillar['foo']|join('", "') }}"]
}

however if you need to escape possible double quotes you can use:

{
"foo": [
{%- for foo in pillar['foo'] -%}
"{{ foo|replace('"', '\\"') }}"
{%- if not loop.last -%}
,
{%- endif -%}
{%- endfor -%}
]
}

Sorry, I meant to say "if you know that your pillar variables will never
contain double quotes"

this might be a longshot, but salt has a mongodb "returner" module, which seems like it would produce valid json at some point.

Salt has a custom Jinja filter that will convert variables to a JSON string:

{
  "foo": {{ pillar['foo'] | json() }}
}

Thanks everyone. I think this solution seems promising and elegant.
