Symfony Admin生成器 - 显示Doctrine Collection

Question

In my model i have:

 * @method Doctrine_Collection getComments() Returns the current record's "Comments" collection

Default if i generated admin then this isn't showing in list. If is in generator.yml :

config:
  actions: ~
  fields:  ~
  list:    
    display: [id, title, comments]
  filter:  ~
  form:    ~
  edit:    ~
  new:     ~

Then this show me

<pre> Doctrine_Collection data : Array( ) </pre>

instead of list of comments.

I know - i can get files from cache and showing this, but maybe this is possible only with generator.yml ? For example if i have relation one to many then this showing me this name.

I dont want use cache for this! thanks!

Answer 1

you can use a function for your problem.

For example, in my generator.yml

  list:    
    display: [id, description, public, nbQuestions]

nbQuestions is a function in Object.class.php

public function getNbQuestions() {
    return $this->getQuestion()->count();
}

The admin generator will automatically call the "getYouField" Method in the object class. So you can describe a function which return a long string for you doctrine collection.
