I'm having issues with an array returned from DB::select()
. I'm heavily using skip
and take
on Collections
of eloquent models in my API. Unfortunately, DB::select returns an array, which obviously doesn't work with skip and take's. How would one convert arrays to a collection that can utilise these methods?
I've tried
\Illuminate\Support\Collection::make(DB::select(...));
Which doesn't quite work as I expected, as it wraps the entire array in a Collection, not the individual results.
Is it possible to convert the return from a DB::select
to a 'proper' Collection that can use skip
and take
methods?
Update
I've also tried:
$query = \Illuminate\Support\Collection::make(DB::table('survey_responses')->join('people', 'people.id',
'=', 'survey_responses.recipient_id')->select('survey_responses.id', 'survey_responses.response',
'survey_responses.score', 'people.name', 'people.email')->get());
Which still tells me:
FatalErrorException in QueryHelper.php line 36:
Call to a member function skip() on array
Cheers
For anyone else that's having this sort of problem in Laravel, I figured out a work around with the following solution:
$query = DB::table('survey_responses')->join('people', 'people.id', '=', 'survey_responses.recipient_id')
->select('survey_responses.id', 'survey_responses.response', 'survey_responses.score', 'people.name', 'people.email');
if(isset($tags)){
foreach($tags as $tag){
$query->orWhere('survey_responses.response', 'like', '%'.$tag.'%');
}
};
// We apply the pagination headers on the complete result set - before any limiting
$headers = \HeaderHelper::generatePaginationHeader($page, $query, 'response', $limit, $tags);
// Now limit and create 'pages' based on passed params
$query->offset(
(isset($page) ? $page - 1 * (isset($limit) ? $limit : env('RESULTS_PER_PAGE', 30)) : 1)
)
->take(
(isset($limit) ? $limit : env('RESULTS_PER_PAGE', 30))
);
Basically, I wasn't aware that you could run the queries almost incrementally, which enabled me to generate pagination chunks before limiting the data returned.
I would try:
$queryResult = DB::table('...')->get();
$collection = collect($queryResult);
If the query result is an array, the collection is filled up with your results. See the official documentation for the collection. Laravel5 Collections
