attribute

The attribute function can be used to access a «dynamic» attribute of a variable:

{{ attribute(object, method) }}
{{ attribute(object, method, arguments) }}
{{ attribute(array, item) }}

In addition, the defined test can check for the existence of a dynamic attribute:

{{ attribute(object, method) is defined ? 'Method exists' : 'Method does not exist' }}

Примечание

The resolution algorithm is the same as the one used for the . notation, except that the item can be any valid expression.
