symfony2. How to make a list of something from the database displayed on all pages?

Question

symfony

Hello dear experts!
Please help me solve the problem, I need to display the category block on all pages. There are 18 pages in total, and 18 routes for them. How to do this without passing a selection with categories in each controller and action?

Answer 1

The most obvious is to call the controller that displays the category block in the base layout, from which all other views are inherited.

{% block categories %}
  <h2>Категории</h2>
  {{ render(controller('YourBundle:YourCategoryController:index')) }}
{% endblock %}

Answer 2

You can look towards services, or TwigExtension

Answer 3

What about the onKernelRequest event?

Answer 4

You can use the block from sonata-project.org/bundles/block/master/doc/refere...
