Concatenate suffix to a twig method

Question

I have a method in class , which the last two characters returns a value or another. The methods are:

getLastnameAD, getLastnameIN getLastanemBB

I want to use a macro to pass two characters to get the value, more or less as follows.

{% macro getLastName (obj, suff) %}
    <span>Lastname: {{ obj.getLastname ~ suff }}</span>
{% endmacro %}

But I get the following error;

Method "getLastname" for object ... does not exist in ...

Do you know if do this is possible ? If it is not possible. Is there any solution ?

I can not edit the object and the method that generate it, so, i have to get it in the view because it is the only place where I can handle data.

Greetings and thank you.

Answer 1

The error that you showed is because Twig is trying to execute the getLastname() method in your object and it's not defined.

The solution is the one provided by @qooplmao in a previous comment and use the attribute() function :

{{ attribute(obj, 'getLastname' ~ suff) }}
