whereHas feature — even more sugar

[Cellard]

Lets say, we have models City and Street with hasMany and belongsTo relationships.

If we need to find the city that contains the street, we write:

$city = City::whereHas('street', function($query) use ($street) {
   $query->whereKey($street->id);
})->first();

But it may be simplified that way:

$city = City::whereHas('street', $street)->first();

Or even:

$cities = City::whereHas('street', $collectionOfStreets);

Framework can do this work.

What do you think about this feature?

(Of course, the feature is also applicable to whereHasMorph)

It's not a bad idea, similar to something I was thinking the other day.

$city->streets()->whereKey($street->id)->exists()

Would be cool if you could do

$city->streets()->contains($street->id);
