Why is {attribute} not being replaced with the attribute name?

Question

Yii

In the model

$this->addError('email', '{attribute} уже занят.');

Prints '{attribute} already taken.'

Answer 1

messages of the format '{attribute} already taken.' support built-in validators, but you add error messages through the addError model method, which does not support this message format. Specify the attribute name explicitly, for example:
$this->addError('email', 'email уже занят.');

Answer 2

$this->addError('email', "{$attribute} is already taken.");
