Collection of free resources to dive into Node.js.

I prefer quite small, useful and clear articles/books (and I would not be so clever to post official docs links here, I hope you have already found it and know what to do in case of emergency :)).
I'll try to order it from very basic to more sophisticated, so if you don't know where to start... just start from the very beginning of the list.

Official CHANGELOG appeared so my digests could be not so useful now
but in any case I will keep going :)

What's new

• Validator in Yii can be used without model - long awaited feature
• Getting started with Yii2 development documantation. Decribes the best way to have a locally runnable webapp that uses codebase cloned from main repository
• Extension guidelines

Namespace and package names Extension MUST use the type yii2-extension in composer.json file. Extension MUST NOT use yii or yii2 in the composer package name or in the namespaces used in the package. Extension SHOULD use namespaces in this format vendor-name\package (all lowercase). Extension MAY use a yii2- prefix in the composer vendor name (URL). Extension MAY use a yii2- prefix in the repository name (URL). etc...

@cebe : I think we can close this issue now. I am done with all the system I know and can support as I am going to work with them on a regular basis. Others should be provided as extensions or by other core developers. If someone wants to start working on an implementation of an AR feel free to contact me, I can help with that.

  ', [':status' => 1])->queryScalar();

  $dataProvider = new SqlDataProvider([
      'sql' => 'SELECT * FROM tbl_user WHERE status=:status',
      'params' => [':status' => 1],
      'totalCount' => $count,
      'sort' => [
          'attributes' => [
              'age',
              'name' => [
                  'asc' => ['first_name' => SORT_ASC, 'last_name' => SORT_ASC],
                  'desc' => ['first_name' => SORT_DESC, 'last_name' => SORT_DESC],
                  'default' => SORT_DESC,
                  'label' => 'Name',
              ],

      ],
      'pagination' => [
          'pageSize' => 20,
      ],
  ]);

First all be aware of Apple's policy as for auto renewable subscription and application types that could use it (your app could be rejected if reviewers will decide you that you are missusing subscriptions).

11.15 Apps may only use auto renewing subscriptions for periodicals (newspapers, magazines), business Apps (enterprise, productivity, professional creative, cloud storage) and media Apps (video, audio, voice), or the App will be rejected

Auto renewable subscriptions flow

Basically it works as all AppStore in-app purchases - iOS makes purchase on client side, receives Receipt and gives it server for validation. An issue appears when you need to renew subscription - unfortunately there is no something like IPN in PayPal and AppStore does not "push inform" us about prolongation or cancellation of subscription (as PayPal do). We need to do it ourselves.

As for auto-renew subscriptions we should make such steps:

• Take initial receipt, validate it on server side (what should be validated except Apple response - is a topic for another big post)
• Store initial receipt in DB (assign to user internally and save renew date)
• CRON job should make periodic check of records by renew date (frequency depends on your logic, but once in 1-6 hours could be fine)
• If it is time to check some subscription - take previously saved Receipt and make a validate request to Apple server as usually
• If subscription was continued and money booked from user - you will receive response with new Receipt (and old one also), if not renewed - you will receive "Expired" response.
• If subscription was continued and success response received - save it to DB, and use in next subscription validation round
• If not - process your app logic on expired subscription (close some services for this user or something)
