Automatyczne uaktualnienie

Narzędzie Automatyczne uaktualnienie pozwala administratorowi sklepu na utworzenie kopii zapasowej i aktualizację PrestaShop za pomocą kilku kliknięć i nie wymaga wiedzy technicznej.

Moduł 1-Click Upgrade jest częścią standardowej instalacji PrestaShop i powienien być dostępny w zakładce "Moduły" panelu administracyjnego. Wystarczy nacisnąć przycisk "Instaluj" znajdujący się obok ikonki tego modułu, żeby zyskać możliwość zaktualizowania sklepu do najnowszej wersji.

 

 

Nigdy nie powinno się aktualizować sklepu bez przygotowania. Automatyczne uaktualnienie może w pewnych sytuacjach ulec awarii, a przywrócenie poprzedniej wersji może w tej sytuacji się nie powieść.
Najbezpieczniejszą praktyką jest umieszczenie dokładnych kopii sklepu - jednej na Twoim komputerze lokalnym, a drugiej w osobnym folderze na Twoim serwerze WWW. Taka kopia powinna zawierać wszystkie produkty, kategorie, szablony, moduły, tłumaczenia, pliki konfiguracyjne itd.
Zalecamy przeprowadzenie próbnej aktualizacji na kopii sklepu. Kiedy proces zostanie zakończony, należy dokładnie przejrzeć sklep i jego funkcjonowanie zarówno od strony użytkownika, jak i od strony panelu administracyjnego, aby upewnić się, że wszystko działa i wygląda jak należy. Jeśli tak nie jest, prawdopodobnie zachodzi jakiś konflikt między narzędziem Automatycznego uaktualnienia, a ustawieniami sklepu. W tej sytuacji powinieneś zastosować metodę ręcznej aktualizacji, która choć nie jest już rozwijana i jej zastosowanie zabiera więcej czasu, może okazać się jednak pomocna.

 

 

Pobieranie i instalacja modułu 1-Click Upgrade

Jeśli modułu 1-Click Upgrade nie ma w Twoim sklepie PrestaShop w wersji 1.4 lub 1.5, możesz pobrać go bezpłatnie ze strony Addons. 

 

Nawet jeśli moduł 1-Click Upgrade masz już zainstalowany, upewnij się, że jest to najnowsza wersja tego modułu.

  • Jeśli Twój sklep to PrestaShop 1.4: Sprawdź numer wersji w zakładce "Moduły", a następnie porównaj go z numerem  wersji gotowej do pobrania na stronie Addons (więcej informacji na ten temat znajduje się poniżej). Jeśli numery różnią się, pobierz moduł ze strony Addons i zaktualizuj go.
    • W celu zaktualizowania modułu: odinstaluj, a następnie usuń "stary" moduł w zakładce "Moduły" panelu administracyjnego. Dalej, rozpakuj folder skompresowany "nowego" modułu, który pobrałeś ze strony Addons. W utworzonym w ten sposób folderze odszukaj folder "/autoupgrade", a następnie (używając na przykład protokołu ftp) skopiuj go do folderu "/modules" znajdującego się na Twoim serwerze. Następnie zainstaluj moduł 1-Click Upgrade w panelu administracyjnym Twojego sklepu.
  • Jeśli Twój sklep to PrestaShop 1.5 lub nowszy: PrestaShop automatycznie sprawdzi, czy Wersja modułu, którą posiadasz jest wersją najnowszą. will automatically check the Addons site for new versions of your modules. If a new version is available, it will present a new button "Upgrade!" button next to the "Install/Uninstall" button. Click to have PrestaShop download and update the module for you.

Simply follow the normal path to installing a module on PrestaShop:

  1. Download the 1-Click Upgrade module from PrestaShop Addons: http://addons.prestashop.com/en/administration-tools/5496-autoupgrade.html. Save the Zip file to your desktop.
  2. In your PrestaShop administration panel, go to the "Modules" page of the "Modules" menu.

  3. Click on the "Add a module" button, located at the top right of the list of available modules.

     

    If updating from version 1.4, click on the "Add a module from my computer" link, located at the top left.

  4. In the form that opens, click on the "Browse..." button, then find and select the module's Zip file that you just downloaded.
  5. Click the "Upload this Module" button. PrestaShop will put the module on your server, unzip it, and place the files in the /modules folder.

The module is now available in your list of modules, but you still have to install it:

  1. In the "Modules" tab, find the 1-Click Upgrade module: type "1-click upgrade" or "autoupgrade" in the module search box (not the global search at the top). A direct link to the module should appear as you type. Click it.
  2. PrestaShop then displays the module in the main module list.
  3. Click the module's "Install" button.

The module is now ready to configure and use.

The configuration Screen

The module's configuration screen is available from the "Modules" list, by clicking on the module's "Configure" link.

 

The configuration screen is also available from:

  • PrestaShop 1.4: under the "Tools" tab, in the "1-Click Upgrade" sub-tab.
  • PrestaShop 1.5 and later: under the "Advanced parameters", in the "1-Click Upgrade" page.

The configuration screen presents you with a series of sections, providing information, tools and settings.

Welcome

This small section serves as a reminder that an upgrade is never 100% safe, and therefore that you should make sure you have made a complete backup of your files and data. This way, should the upgrade fail, you will be able to return to the initial state of your shop – albeit with a bit of work putting your files and data back into place.

This process is explained in details in the "Making and restoring your own backup" chapter of this guide:http://doc.prestashop.com/display/PS16/Making+and+restoring+your+own+backup.

Note that the 1-Click Upgrade module performs its own set of backup in order to allow for reverting of the whole upgrade. Nevertheless, you should rely on your own backups.

The pre-Upgrade checklist

The "The pre-Upgrade checklist" section gives you useful information on your current PrestaShop installation, and how it might interact with the automatic upgrade.

You must make sure that all the checks are validated before you can launch the upgrade.

All these indicators must be green for the upgrade to work. Otherwise, the upgrade button will not appear.

 

When your store is hosted on your local server (http://localhost or http://127.0.0.1), the auto-upgrade module understands that the maintenance mode is not required, since no one else than you can access the site. Therefore, even if you are not in maintenance mode, the module marks that check as valid.

Start your Upgrade

This section compares your version of PrestaShop with the latest stable one. You can quickly see whether you need to update or not. If you know that there is a newer version available than the one presented, you can trigger a version check by clicking the "Check if new version available" button.

By default, the update tool is set to update your store to the next minor version. This means that if you use a version from the 1.4.x branch, it will not suggest the latest 1.6.x version, but rather the latest 1.4.x version. Therefore, if you want to update from a 1.4.x version to the latest 1.6.x version, you must click on the "More options (Expert mode)" button. This will open a new section, named "More options (expert mode)", where you can choose the distribution channel to which you want to update.
This is also very useful if you want to check for a version other than a stable one (for instance, beta, RC or any other unstable version).

Before launching the upgrade, you must make sure that you understand its settings. The "Backup options" and "Upgrade options" sections are available at the bottom of the page (and are described later in this chapter). Make sure you understand them all.

Expert mode

This section enables you to pinpoint exactly to which version you want to upgrade your current PrestaShop installation.

The options are:

Version comparison

For the curious, the numbered differences between your current version and the latest version in the chosen channel.

In case you have make changes directly to the core files instead of using the overriding possibilities of PrestaShop, these lists can help you know if your changes are safe or not.
Nevertheless, you can improve the lifespan of your custom code by turning it into overriding files. See the developer documentation for more information.

Rollback

This section only appears when at least one upgrade has been performed.

See below for more information.

Backup options

These options enable you to have some control on the backup process:

Upgrade Options

These options enable you to have some control on the upgrade process:

The Upgrade process

Once all the indicators in the "pre-Upgrade checklist" section are green, the update button appears in the "Start your Upgrade" section, along with the URL from which the new version will be downloaded.

Clicking the "Upgrade PrestaShop now !" button triggers the whole process.

Once the upgrade process is launched, the whole configuration page is replaced by two sections: "Activity Log" and "Rollback".

The activity log gives you a detailed journal of what the updater is doing, in a screen you can scroll through:

A lot of files are mentioned during the whole process. You do not need to read all the notifications, it's only there for you to peruse in case of error.

You'll know the upgrade is over when the following message "upgrade complete. Please check your front office theme is functional (try to make an order, check theme)" appears in green, along with the following final log entry: "End of process". 
The upgrader also indicates that you should re-enable your shop, but before you do that, you should first check that everything is working in your back office: no errors, all products and categories are in place with their images and attached files, etc. Until you have checked that everything is okay in your shop, it is better to keep it from the public eye.

 

On first load, pages might look wonky: because your web browser caches files, it is probably using the old CSS files instead of the new ones. Do not hesitate to reload the page several times, or even empty your browser's cache, in order to get the correct interface.

 

When you upgrade from version 1.4 to version 1.6, your menus will not be arranged the way they would be if you made a fresh installation of version 1.6.

That is because PrestaShop 1.4 tabs got reorganized into 1.6 menus, and a lot of pages were moved around in order to create consistent menus. Additionally, the upgrader assumes that your 1.4 tabs may have been customized or moved around, either by a module or by your own action. Therefore, rather than breaking the existing settings, the upgrader takes the tabs as-is, and does not re-arrange them into the default 1.6 menu order.

If you want to change the position of pages within a menu once you have updated to version 1.6, go the to "Menus" page under the "Administration" menu, and start fiddling with positions.

Once you have made sure your PrestaShop installation is up and running, you can re-enable your shop using the option in the "Maintenance" page of the "Preferences" menu, then make tests on your front office: browse products, sort them, try to order one, etc. In short, go through the entire buying process in order to make sure that you won't miss a sale.

Is everything working fine? Congratulations, you know have successfully upgraded your PrestaShop installation!

JavaScript error

 

In some server configurations, an error message might be displayed, saying "Javascript error (parseJSON) detected for action "upgradeNow". Starting restoration...".

Follow these steps to solve the error, :

  • Open your php.ini file and enable (uncomment) the MySQLi and MySQL PDO extensions. If you cannot access the php.ini file, contact your web host about this.

  • Open the /modules/autoupgrade/db/Db.php and find these lines (around line 210):

     

    public static function getClass()
    {
        $class = 'MySQL';
        /*if (PHP_VERSION_ID >= 50200 && extension_loaded('pdo_mysql'))
            $class = 'DbPDO';
        else if (extension_loaded('mysqli'))
            $class = 'DbMySQLi';*/
        return $class;
    }

     

    Simply uncomment these lines (remove /* and */). They should now look like this:

     

    public static function getClass()
    {
        $class = 'MySQL';
        if (PHP_VERSION_ID >= 50200 && extension_loaded('pdo_mysql'))
            $class = 'DbPDO';
        else if (extension_loaded('mysqli'))
            $class = 'DbMySQLi';
        return $class;
    }

After you have done all this, start the autoupgrade process again.

Going back to the previous version: rollbacks

Sadly, not all upgrades are successful – which is the very reason why you should always back-up all your files and data, and why PrestaShop performs an additional backup of said files and data by itself, which you should not always count on. Make your own backup first. See the "Making and restoring your own backup" chapter of this guide for more information.

PrestaShop's own backup files are saved on your server, and if it turns out your update has gone badly, you can find them in the "Rollback" section of the configuration page for the 1-Click Upgrade module.
Backup files are created as soon as the upgrade process is started, and are available immediately in the "Choose your backup" drop-down list.
Choose the most recent one. The date and hour of the creation of the backup file are right within the name: Vversion-date-hour-random, for instance "V1.4.9.0_20120907-114024-f85f41a" for a backup of a previous PrestaShop 1.4.9 installation, made September 7th 2012, at 11:40:24 AM.

The "Rollback" button triggers two actions:

Select the backup archive to which you want to roll back to, and click the "Rollback" button. As with the upgrade process, the whole interface disappears to only leave the "Activity Log" section and the "Rollback" section. You can follow the rollback process in the scrolling journal, and once it is finished, reload the page in order to check that everything is indeed back in place.

Going back to the previous version: restoring your own backup
