How to make retrieve data from another controller Symfony2 - symfony

Question

I'm new with Symfony2 and I have a question that I could not fully solve by myself. I'm programming an application and use the tables client and project. Every project has one client and every client can have multiple projects.
The autonomous display of clients- and projectstables does already work, but I also have to display the projects in the frontend of clients. I already tried multiple ways to do so but I did not have any success so far.
Could you tell me what I have to put in my ClientController-, config.yml and routing.yml-File in order to display the projecttables in the show.html.twig file of client?
I thank you in advance for your answer

Answer 1

If your entity relations are configured correctly (what they seem to be), then you can acces the projects array direclty in twig:
{% for project in entity.projects %}
Name: {{ project.name }}
...
{% endfor %}
