在树枝Symfony3中的for循环内获取数据

Question

I'm beginner in Symfony, How do I fetch the value of sub_agent.companyId in my company table on views using symfony?

Controller:

public function indexAction(Request $request) {

    $em = $this->getDoctrine()->getManager();

    $sub_agents = $this->getDoctrine()
        ->getRepository('AppBundle:Sub_agent')
        ->findAll();

    return $this->render('Backend/Sub_agent/index.html.twig', array(
        'sub_agents' => $sub_agents
    ));
}

Template: index.html.twig

{% for sub_agent in sub_agents %}

{{ sub_agent.companyId }} // Get the data of this companyId in my company table

{% endfor %}

Answer 1

Try this:

{% for sub_agent in sub_agents %}
 {{ sub_agent.companyId|e }}
{% endfor %}

Answer 2

I think the company has an relation with the sub_agent entity or not?

If it is a seperated entity you should first get the company and after that get the id of the company entity

try this:

{% for sub_agent in sub_agents %}
   {{ sub_agent.company.id }} 
{% endfor %}

Answer 3

Use your getter. Not sure what it is called for your Entity. Something like this:

{% for sub_agent in sub_agents %}
   {{ sub_agent.getId }}
{% endfor %}

It should be as easy as that, since you normally can't call the attribute directly, so just use your Entity setters/getters to get/set them.

EDIT #2 - Based on you didn't mention you had a separate Entity called Company

{% for sub_agent in sub_agents %}
   {{ sub_agent.getCompany.getId }}
{% endfor %}

The above presumes that the sub_agent Entity has a $company attribute and the getter is called getCompany() . Then getCompany() returns a Company object, and then the Company method getId() returns the Company ID. You could also use DanBuit's suggestion, but both Chi-Chi and my suggestions are the "typical" way to do it in Twig.
