Symfony2：如何从数组中获取值并将其打印到twing文件中

Question

I am new to Symfony. I am currently using symfony2.4 .

where I stuck -

I have one scenario. In which I have to show simple listing in twing file. The data comes from database. This data comes from the two joined tables.

First table is Teams

id

name

nickname

country_id

Second table is Country

id

name

I want to print data like this

     Name     | Nickname | Country(name)

Mumbai Indians| MI       | India
New Royals    | NR       | India

So What I do in my twing file :

<table border=1>
    <tr>
        <th>Name</th>
        <th>Nickname</th>
        <th>Country</th>
    </tr>
{% for team in teams %}
  <tr>
      <td>{{ team.name }}</td>
      <td>{{ team.nickname }}</td>
      <td>{{ team.country }}</td> <<<<<<<<<<<
  </tr>
{% endfor %}

So Here country is not working

This is my controller code

$teams = $this->getDoctrine()
                ->getRepository('AdminSporteventsBundle:Teams')
                ->findAll();

        if (!$teams) {
            throw $this->createNotFoundException('No news found');
        }
        $build['teams'] = $teams;
        return $this->render('AdminSporteventsBundle:Teams:teams_list.html.twig', $build);

Answer 1

You need to do {{ team.country.name }} assuming you have set your relationships up properly.

Updated to reflect entity code.

Answer 2

Yo have mistake in the teams entity at join column annotation. Referencedcolumn generally is id(what's your country primary key). Then try to access country like this

You need to do {{ team.country.name }} in twig assuming you have set your relationships up proper

Answer 3

This part:

/**
 * @var \Admin\SporteventsBundle\Entity\Countries
 *
 * @ORM\ManyToOne(targetEntity="Admin\SporteventsBundle\Entity\Countries")
 * @ORM\JoinColumns({
 *   @ORM\JoinColumn(name="country_id", referencedColumnName="country_id")
 * })
 */
private $country;

need to be changed to:

/**
 * @var \Admin\SporteventsBundle\Entity\Countries
 *
 * @ORM\ManyToOne(targetEntity="Admin\SporteventsBundle\Entity\Countries")
 * @ORM\JoinColumns({
 *   @ORM\JoinColumn(name="country_id", referencedColumnName="id")
 * })
 */
private $country;

as referencedColumnName should be id , not country_id

By doing as above, you will create the relationship properly then in your twig file, you can use:

{{ team.country.name }}

Hope this help :)

Answer 4

In the Teams Entity , at the $country field, try using the following to set the relationship:

/**
 * @var \Admin\SporteventsBundle\Entity\Countries
 *
 * @ORM\ManyToOne(targetEntity="Admin\SporteventsBundle\Entity\Countries")
 * @ORM\JoinColumn(name="country_id", referencedColumnName="country_id")
 */
private $country;

and then you can access the name of your country by typing the following in twig:

{{ team.country.name }}

Answer 5

maybe it's an array , and you must scan it?

 {% for country in team.country %} {{ country.name }} {% endfor %}
