Feature Request: to_array_exclude on ->related();

[alfierivera]

Many of us have encountered a couple of situations where excluding certain fields on a related Model dynamically is necessary.

For such purpose, I think that the following feature should be added to future updates of the ORM.

Use case:

We have an API and we want to expose comments like so /api/comments.
We also want to know who was the user that submitted that comment, but we do not want it's email or password.

Current workaround:

### Model_User:
$_to_array_exclude(array('email', 'password'));

### API Controller:
$comments = Model_Comment::query()->related('users')->get();
$result = array();
foreach ($comments as $i => $comment)
{
    $result[$i] = $comment->to_array();
}

return $result;

Note: This workaround has a big disadvantage. We will always exclude those fields when using ->to_array();

Proposed feature:

## Model_User:
We set nothing on the User's Model.

## API Controller:
$comments = Model_Comment::query()->related('users'=>array('to_array_exclude' => array('updated_at')))->get();
$result = array();
foreach ($comments as $i => $comment)
{
    $result[$i] = $comment->to_array();
}

return $result;

I assume, given your example, this is about Fuel v1? If so, this is the wrong repository.

Partial selects will not be implemented, it's a bad idea. And it's not the task of an ORM to filter data for your API.

We talked about this in IRC, it was a way to dynamically add or remove things from the "to array ignore", which should be easily possible in v2
