Doesn't throw an error for validation in Yii2?

Question

Yii

Validation code:

public $contact;

    public function rules()
    {
        return [
            [['contact'], 'required', 'message' => Yii::t('app', 'The field does not have to be empty!')],
            [['contact'], 'string', 'min' => 4, 'message' => Yii::t('app', 'Contact should contain at least 4 characters.')],
        ];
    }

This code does not work, does not replace the message, how to solve?

[['contact'], 'string', 'min' => 4, 'message' => Yii::t('app', 'Contact should contain at least 4 characters.')],

Answer 1

Found a solution, for the error message when there is 'min' => 4, 'tooShort' => "message error" displays an error, not 'message', well, for 'max' => 50 then 'tooLong' => "message error".

Answer 2

Good evening.
Do you have such a line in the translation file?
Show translation file.
ps
In your translation file, in the returned array, there should be the following line:
And then in the validation rules, you can use it like this:
'message' => Yii::t('app', 'MIN_ERROR')
