Other filters

id

Filter for retrieving a data object's ID. The filter is 'permissive' and checks for keys and attributes called id or extId.

{% if region|id == 'CZ010' %}Městské části{% else %}Okresy{% endif %} v# {{region|name|morph('Case=Loc')}}

• Městské části v Praze.
• Okresy v Plzeňském kraji.

enum (Cs/En)

Generates an enumeration, for example:

• {{['x', 'y', 'z']|enum}} → x, y and z (English)
• {{['x', 'y', 'z']|enum}} → x, y a z (Czech)

Basic mathematical operations

It is possible to use filters for basic mathematical operations like finding a maximum, minimum or summation (and average from it).

Assuming this data:

{ "prices": [32.19, 32.24, 32.21, 36.33, 33.41, 36.33, 31.77, 31.81 ] }

we can generate the following (note the ln filter is used to obtain localized numbers):

• The maximal price is {{prices|max|ln}} EUR. → The maximal price is 36.33 EUR
• The minimal price is {{prices|min|ln}} EUR. → The minimal price is 31.77 EUR.
• The average price is {{((prices|sum)/(prices|length))|ln}} EUR. → The average price is 33.29 EUR.
