Sonata Admin +显示列表视图中的所有项目（不是每页）

In the Sonata Admin Bundle you have a list view where you can add fields you want to show in your table.

At the bottom of the table you have the number of results and pagination. I like the pagination and items per page. But I would like to show ALL the items at the load of the page. So all the items are shown on the page but you can still choose to decrease the number of results per page.

The problem is I don't have a clue on how to do this. Can someone set me on my way?

Actually, it is possible to do. You have in you EntityAdmin to

a) Define a list of possible "Results per page" values.

Now it is protected $perPageOptions = array(16, 32, 64, 128, 192);

So the easiest solution could be just to put a new really big number, foe example

protected $perPageOptions = array(16, 32, 64, 128, 192, 1000000);

But if you want to make really "all", then you must do

protected $perPageOptions = array(16, 32, 64, 128, 192, 'All');

and then

2) redefine a method EntityAdmin::buildDatagrid() to process this 'All' value of $filterParameters['_per_page']

In SonataAdmin 3.x to have all rows by default you need to do the following :

1 - Add _per_page = All to $datagridValues :

 protected $datagridValues = array(
    '_sort_order' => 'ASC',
    ...
    '_per_page' => 'All',
);

2 - Add All to $perPageOptions:

protected $perPageOptions = [16, 32, 64, 128, 192, 'All'];

3 - Set $maxPerPage to All:

protected $maxPerPage = 'All';

class YourAdmin extends AbstractAdmin
{
    protected $perPageOptions = [64, 128, 256, 'All'];

    protected $datagridValues = [
        '_per_page' => 'All',
    ];

    protected $maxPerPage = 'All';

    ...
}

If you find $maxPerPage variable as strange or redundant ask him @author Thomas Rabaix thomas.rabaix at sonata-project dot org
