Laravel 5.3无法使用派生字段对模型进行分页

Question

I have a Property model and I have made the following scope:

public function scopeSearch($query, $search)
{
    return $this->addSelect(DB::raw("( 3959 * acos( cos( radians(".$search['latitude'].") ) * cos( radians( properties.latitude ) )
                      * cos( radians( properties.longitude ) - radians(".$search['longitude'].") ) + sin( radians(".$search['latitude'].") )
                      * sin( radians( properties.latitude ) ) ) ) AS distance"))
        ->having('distance', '<=', $search['radius']);
}

If I then try and get some paginated results like so:

$properties = Property::search($search)
        ->addSelect('properties.*')
        ->paginate($this->per_page);

I get the following error:

QueryException in Connection.php line 729:
SQLSTATE[42S22]: Column not found: 1054 Unknown column 'distance' in 'having clause' (SQL: select count(*) as aggregate from `properties` where `properties`.`deleted_at` is null having `distance` <= 25)

Looks like the pagination is doing a count query that doesn't run the addSelect() methods so the field distance doesn't exist. Is there a way to get it to add the selects as well?

Full stack trace:

Answer 1

What you can do is copying the whole definition of distance column into having part. In fact you should use havingRaw function to achieve this.

However you should for both addSelect and havingRaw use bindings because now your code is vulnerable to SQL injection.
