Page.extra array selector

1

given front matter with an array as such

+++
[extra]
features = [
        {name="Weight", value="1.12 kg"},
        {name="Dimensions", value="4 x 8 m"},
]

is it possible to select one matching a selector along the lines of

page.extra.features[name='Weight']

2

Possibly a bit verbose but maybe something like this? If I understood correctly.

{% for feature in page.extra.features %}
    {% if feature.name is matching("Weight") %}
        {{ feature.name }}
    {% endif %}
{% endfor %}

Corresponding tera docs.

Yes, i’m currently doing that. It’s nasty.
I was hoping some short cut existed for accessing objects.

its possible to access a value using the key

{{ page.extra['title'] }}

and also possible to access an object (not within an array) given

+++
[extra]
weight = {unit="kg", value=1.2}

both forms access the object in the template

{{ page.extra.weight.value }} {{ page.extra.weight.unit }}
{{ page.extra.weight['value'] }} {{ page.extra.weight['unit'] }}

but not for accessing an object WITHIN an array.

+++
[extra]
features = [
        {name="Weight", value="1.12 kg"},
        {name="Dimensions", value="4 x 8 m"},
]

ill try the some tera ‘built-ins’

The tera filter looks promising

page.extra.feature | filter(attribute='name', value="Weight")}}

Looks like it returns an array of object. Now to access the first element in the array.

{% set x = page.extra.feature | filter(attribute='name', value="Weight") | first %}
{{x}}

Would like to access that in one line but this is a good start
