In my module, I am adding small snippet to every page on site with layout file, that I have attached below. The thing is, I would like to disable caching for my module. How do I do that without disabling FPC for whole page? Using cacheable="false" will make whole page non-cached. So this option won't work for me.

I have already tried following:

  1. controlling cache through the constructor, my block derives from \Magento\Framework\View\Element\Template and setting up cache like this : $this->addData(array('cache_lifetime' => null)); didn't work.

  2. adding parameters to my block in layout file:

    <page xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:View/Layout/etc/page_configuration.xsd">
        <body>
            <referenceContainer name="content">
                <block class="Something\Something\Block\SnippetBlock" name="snippetblock" template="snippetblock.phtml"> 
                 <arguments>
                                    <argument name="cache_lifetime" xsi:type="null">null</argument>
                          </arguments>
            </block>
            </referenceContainer>
        </body>

  3. overwriting getCacheLifetime() method to return null. And this is my layout file that I am using now:

    <page xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:View/Layout/etc/page_configuration.xsd">
<body>
    <referenceContainer name="content">
        <block class="Something\Something\Block\SnippetBlock" name="snippetblock" template="snippetblock.phtml" />
    </referenceContainer>
</body>

I will gladly listen to any suggestion.

  • Have you try to caching magento, and then check? – Dhiren Vasoya Jul 31 '18 at 10:45
  • Each time I am altering my code I am doing bin/magento cache:clean just to be sure. – Michał Paszowski Jul 31 '18 at 10:55

In Magento2, You have to render the content via JS (Ajax).
Check how the mini-cart & login/logout section has been implemented.

Note: There is no concept like hole-punching like in Magento 1.

Please use this code for your construct method.

public function _construct(
    \Magento\Customer\Model\Session $session
) {
    $this->_isScopePrivate = true;
    $this->customerSession = $session;
}

  • It didn't work for me unfortunately. Maybe I am testing it in wrong way: 1 when page cache is disabled i can modify manually code of my snippet refresh page and see the changes. 2 when page cache is enabled I am modyfing code refresh page but changes do not appear until I flush the cache. I would expect that if one of above methods for disabling cache would work the effect would be the same as in point 1. – Michał Paszowski Jul 31 '18 at 11:27
