How about a FAQ as the last chapter?

[markch123]

I quite like FAQs even if they are a bit antiquated :) And from the perspective of a lazy contributor its pretty easy to spend 5-10 minutes adding a question/answer to a list

Maybe its an idea to simply edit this comment with the list ? Rather then adding to the bottom of the thread and starting discussions on particular questions. Also another suggestion could be that each answer should be shortish 1/2 sentences and then a link to the official Yii2 guide (or cookbook!). If there is a better answer in SO then maybe the user guide should be updated or extended :)

The list of course could potentially get huge so at some stage would need to split into categories. But for now maybe just keep it simple. Actually maybe its just easier to start now and follow the Yii guide chapter structure :)

Let's do FAQ session right here and see where it leads to. Ask anything.

[Anton Marin]

Is any example of layered architecture? Or something like

In general, it's out of scope of the framework and would look exactly the same no matter which framework is used. Many examples could be found searching for DDD.

[Anton Marin]

Seems like there is no questions ))

It would be great to have something like that on the new Yii 2 website where you can add / edit questions and answers. StackOverflow is one of the main sources of perfect FAQ examples - countless times I've answered questions like "how to remove label on radioList?", "how to change template on checkbox field?", "why composer returns error about bower?" and so on...

[Alexander Makarov]

We could just link to SO :)

[Bizley]

True 😄 but not every question there can be answered in 1-2 sentences.

[Nikola Kostadinov]

I have some questions/issues which I had workaround for now, but if you could give me a better way to do it would be nice:

1. How to extend controllers ?
2. How to dynamically add fields to form with validation ?
3. How to properly refresh GridView in nested pjax component ?

[Alexander Makarov]

1. How to extend controllers ?

BController extends AController? Same as any other PHP class.

1. How to dynamically add fields to form with validation ?

https://github.com/samdark/yii2-cookbook/blob/master/book/forms-activeform-js.md#adding-and-removing-fields-dynamically

1. How to properly refresh GridView in nested pjax component ?

What's "nested pjax component"?

[Nikola Kostadinov]

1. Seems obvious but the problem is that the action you want to override returns already rendered string. So you cannot do anything from there on e.g. add/modify variables sent to view, render other view etc
2. 10x for that :)
3. Sorry about that - I tested it now and now it works, may be it was an old issue. By nested pjax I mean

<?php \yii\widgets\Pjax::begin() ?>
<h2>Nested pjax</h2>
<div>
    <?php \yii\widgets\Pjax::begin() ?>
    <?= \yii\grid\GridView::widget([...]) ?>
    <?php \yii\widgets\Pjax::end() ?>
</div>
<?php \yii\widgets\Pjax::end() ?>

If you need to override controller action, most probably, you're on a wrong way to a huge architectural mess. Extract contents of controller into domain layer, and call it from different controller actions.
