![]() ![]() Therefore I have implemented a hook_menu_local_tasks_alter() in my_module/my_module. By leveraging cache contexts, Drupal can serve personalized content while still benefiting from caching. With the module and routes created, we can now start playing with Drupal caching.In DefaultController.I have the following situation: I want to hide or show some local Tasks (Tabs) based on a field on the current user. Cache Contexts: Cache contexts allow Drupal to vary cache entries based on different conditions, such as user roles, languages, or device types. Now we should have an *.info.yml, *.routing.yml and our controller class.inally, let’s enable our custom module: $ drupal module:install d8_cache Cache “max-age” Cloudflare ended support for Drupal 7 in 2016. Note for Drupal 7 website owners: This document applies only to Drupal 9 and 10. **Title** **Method Name** **Path** cacheMaxAge cacheMaxAge /d8\_cache/max-age cacheContextsByUrl cacheContextsByUrl /d8\_cache/contexts cacheTags cacheTags /d8\_cache/tags Allow the Drupal administrator to tell Cloudflare to purge all its content in its cache for the website so that visitors will get new (updated) content rather than old (cached) content. Let’s make one route for each of the cache types: When creating the controller, you’ll enter into a loop where you can enter three pieces of information necessary for the controller to define a route: The title, method name, and the path. For instance, let us consider a block displaying a list of tutorial links on a D8 instance. We can use Drupal Console to generate the controller too: $ drupal generate:controller -module=d8_cache - class = DefaultController Cache Context is basically a service that helps in creating multiple cached versions of something depending upon the context/request be it a view, block or any other section on the page. We also need a controller to respond to incoming requests. For instance, 'user' is mapped to the current user's ID.Ĭreating the module and controller $ drupal generate:module -machine-name=d8_cacheĪ module alone isn’t enough. These are converted to a final value depending on the request. contexts specifies one or more cache context IDs.tags is an array of one or more cache tags identifying the data this element depends on.max-age stores cache data by defining its time in integer format and seconds.But what kind of caching? Drupal 8 provides several kinds out of the box: When we have a render array, instructing Drupal to cache the results is easy, we only need to use the #cache property. Drupal ( / drupl /) 5 is a free and open-source web content management system (CMS) written in PHP and distributed under the GNU General Public License. ![]() If you’re interested in more about render arrays, see Render arrays from official Drupal docs. In the configuration of the View, the cache is set 'Tag based' Each user have a specific property, and I want the Views to deal with it, without totally disable the cache of the Views. A render array is an associative array that represents a one or more HTML elements, properties and values. 2 I would like to set a user cache context to a Views, but I don't know where to do this (in what hook ). ![]() While render arrays are a complex topic, let’s cover the basics.
