Templating stops working when lovelace_gen is used! #44

Open Aleborg opened 1 year ago

Aleborg commented 1 year ago

When using lovelace_gen in a yaml file the all templating stops working. states, state_attr etc HA, HACS, lovelace_gen, auto-entities etc is all up2date with the latest versions.

Working:

type: custom:auto-entities
card:
  type: entities
filter:
  template: |
    {% for light in states.light %}
      {% if light.state == "on" %}
        {{ light.entity_id}},
      {% endif %}
    {% endfor %}

Not working:

# lovelace_gen

type: custom:auto-entities
card:
  type: entities
filter:
  template: |
    {% for light in states.light %}
      {% if light.state == "on" %}
        {{ light.entity_id}},
      {% endif %}
    {% endfor %}

I have exactly the same problem. This line crashes the whole dashboard:

{% set names = state_attr('input_select.radio_names', 'options') %}

A little bigger example:

# lovelace_gen
{% set names = state_attr('input_select.radio_names', 'options') %}
title: My test view
cards:
  - type: custom:mushroom-title-card
    title: >
      {{ names }}
mcholcha commented 1 year ago

Ehh, now I just read that we can't use state or attributes. Pity, I thought I had solved the problem of a globally accessible key/value list :(

@Aleborg in your case you need to wrap the templating code by {% raw %}

d2kagw commented 1 year ago

I'm curious @mcholcha, where did you read about not being able to use states or attributes?
