[FIXED] Cakephp 3 paginator sort fields with translate behavior i18n

Issue

I have a Posts table with Translate behavior and I want to sort it by title on the table at index view. I can't sort by the fields that are translated because the field's don't actually exist on the database. They exist on the i18n table.

This, as I explained above, doesn't work:

$this->Paginator->sort('title');
$this->Paginator->sort('Posts_title_translation.content');

So, what I should do? What am I missing?

Many Thanks!

Solution

The second variant should work once the field is being whitelisted, which is generally necessary for associations to be used for sorting:

$this->paginate = [
    // ...
    'sortWhitelist' => [
        'Posts_title_translation.content',
        // ...
    ]
];

Note that with the whitelist in place, you will have to add all other fields of your Posts table that need to be used for sorting too!
