Laravel 4: How to add scope to DB::table?

Question

With Eloquent models adding scopes is easy:

public function scopeMyScope($query)
{
   // Do stuff to that $query
}

But how to add scope to

Answer 1

DB::table doesn't have support for scopes. What you could do is simply write a little function that does some things with the query and returns it. The syntax isn't as nice but it works:

function applyScope($query){
    $query->whereNotNull('deleted_at');
    $query->where('foo', 'bar');
    return $query;
}

And then:

$query = DB::table('page_views')
    ->where('id', $this->id)
    ->where('agent', 'NOT LIKE', '%bot%');
$query = applyScope($query);
$views = $query->count(DB::raw('distinct session, DATE(created_at)'));

Or a bit a shorter syntax:

$views = applyScope( DB::table('page_views')
                       ->where('id', $this->id)
                       ->where('agent', 'NOT LIKE', '%bot%')
         )->count(DB::raw('distinct session, DATE(created_at)'));
