Symfony3+Twig How to make a global variable?

Question

symfony

Good evening.
Please tell me how to implement a global variable, for example {{ tags.name }}, with the output of a specific value from the database in any template.

Answer 1

Make a service that can give you the data you need upon request of the desired method.
And inject the service into twig.
In config.yml:

twig:
    globals:
        your_service: '@your_service'

In twig, you can just pull a {{ your_service.someMethod() }}
