Documentation on hasMany association

[thejoelinux]

Following closed issue #16, documentation on the subject is needed. I set up a small sample project on https://github.com/thejoelinux/cakephp-dt-test to have a test case.

I want to have a list of customers in datatables, with the number of invoices for each, or the sum of invoices if possible.

I try to find a way to do so, but in the meanwhile, any help would be very much appreciated.

@thejoelinux you will need to do something along the lines

in Template.../datatables/configName.ctp

$results->select([
 'invoice_count' => $results->newExpr()->add('sql expression that counts');
 'invoice_count' => $results->func()->count('Invoices.id')
]);
$results->group('Customers.id');

Can use either method, I think.

Thanks for the tip. I used this in my sample project, issue 2, and I will soon commit a solution. It was pretty easy ... once done :)

Next, I'll propose a documentation patch here.
