Why does pull and push return Illuminate\Database\Eloquent\Builder intead of int

[bitinn]

I am very likely doing something wrong but i can't seem to figure it out. my query is as simple as this:

MyModel::where('_id', $id)->pull(array(
    'feeds' => array('url' => $url),
));

feeds is an array of feed, i try to find the matching feed url and pull such feed.

But instead of returning 0 or 1, it returns Illuminate\Database\Eloquent\Builder object.

This doesn't make any sense even when i look at the source code, performUpdate should return n, and it should be int right?

PS: I am on commit 76781d7

interesting, so DB::collection does return int, but not for model. by design?

        DB::collection('my.model')->where('_id', $id)->pull(array(
            'feeds' => array('url' => $url),
        ));

PS: should add that MyModel::update does return int, which seems to suggest otherwise...

so this is the call stack:

#0  Jenssegers\Mongodb\Query\Builder->push()
#1  call_user_func_array() called at [/var/www/leaf/vendor/laravel/framework/src/Illuminate/Database/Eloquent/Builder.php:872]
#2  Illuminate\Database\Eloquent\Builder->__call()
#3  Illuminate\Database\Eloquent\Builder->push() called at [/var/www/leaf/app/models/BaseModelMongo.php:209]

Jenssegers\Mongodb\Query\Builder->pull()
#1  call_user_func_array() called at [/var/www/leaf/vendor/laravel/framework/src/Illuminate/Database/Eloquent/Builder.php:872]
#2  Illuminate\Database\Eloquent\Builder->__call()
#3  Illuminate\Database\Eloquent\Builder->pull() called at [/var/www/leaf/app/models/BaseModelMongo.php:213]

seems like __call on Illuminate/Database/Eloquent/Builder use a $passthru to controll if builder should be returned or not. adding push and pull make my test works.
