{
    return $this->hasOne(Client::className(), ['id' => 'client_id']);
}

but when i generated crud, in client filed just input text field. Help me please, where is problem?

Answer 1

That's correct. In your _form.php file you have to define a dropdown box if the user should choose a client:

<?= $form->field($model, 'client')->dropDownList($clients) ?>

and in controller actions create/update you have to provide the $clients:

return $this->render('create', [  // or: return $this->render('update', [
    'model'    => $model,
    'clients' => ArrayHelper::map(Client::find()->all(), 'id', 'name'),
]);

Don't forget to pass them in the view files for create.php and update.php to the _form.php file:

<?= $this->render('_form', [
    'model' => $model,
    'clients' => $clients, // <-- added
]) ?>

In other views where you just want to show client you may use this:

echo $model->client->name; //or something different
