php symfony doctrine:generate-admin backend Author
php symfony doctrine:generate-admin backend Book

Now i want in the author view a link to his books. What is the best way to do that ? My try is a custom link that pre-selects filters, but i dont know how to do that.

#generator.yml for Author
# ...
    config:
      actions: ~
      fields:
      list:
        display: [id, name, _booksLink]
      filter:  ~
      form:    ~
      edit:    ~
      new:     ~

and

<!-- modules/author/templates/_booksLink.php -->
<a href="<?= link_to('book?author_id='.$author->getId()) ?>"><!-- how to select filter? -->
  See <?= $author->getName() ?> books
</a>

Thanks


This lecture answers your question (slide 39 and 40): http://www.slideshare.net/jcleveley/working-with-the-admin-generator

in your actions.class php add:


class AuthorActions extends AutoAuthorActions
{
  public function executeViewBooks($request) { 
    $this->getUser()->setAttribute( 'book.filters',   
    array('authorId' => $request->getParameter('id')), 'admin_module' ); 
    $this->redirect($this->generateUrl('book')); 
  }
}

Note about the case: The field name matches the case defined in the schema. Eg: if you have authorId in the schema, you must write authorId in the function above (line 5). If you have author_id in the schema, you must write author_id in the function. Also, The module names are always lowercase with underscores (eg: schema : MyBooks -> module name: my_books).

In your generator.yml


list: 
  object_actions:
    _edit: ~
    _delete: ~
    viewPhones: { label: View books, action: viewBooks }
