[FR]: Pass object variables in JSON format when used in templates

[erkr]

Hi code owners

Updated to a FR, 8 June 2024: Decluttering card is really a great project. I recently discovered it and I love it 😊

I noticed that we can pass both object and strings as variables. Directly assign object variables (e.g list) to a key in the card works. I'm stuck passing object variables and use them in templates.

I either get a string that contains [[undefined]], [[variable name]] or the default value 'xxx' declared as a string.

I tried this markdown card template:

  decl_test_var:
    default:
      - VALUE: xxx
    card:
      type: markdown
      content: "{{ '[[VALUE]]' }}"

With this card:

type: custom:decluttering-card
template: decl_test_var
variables:
  - VALUE:
      - tst1.x
      - tst2.y

That doesn't work. There seems no way to pass the object variables into a template

FR: Please pass object variables as a json string when applied inside a template. A special marker like this would be fine:

content: "{{ '[[VALUE:JSON]]' }}"

Thanks in advance Eric

It's because it injects the YAML itself. So VALUE is returning:

- VALUE:
    - tst1.x
    - tst2.y

Instead you can try:

- VALUE: '[tst1.x, tst2.y]'

And remove the quotes around [[VALUE]]

This is really only an issue with Jinja. I use lists elsewhere in my configuration but usually to add cards to a stack.

@droans ah thanks, now I understand what happens. I already found out to pass them as a string, but this was just a simplified example without sub-keys. I will change this question into a FR to pass objects in JSON format when the variables are used inside templates. Thanks!
