Transforming Raw Sql to Laravel equolent - sql

Question

I have written this SQL code
SELECT drugs.*, COUNT(*) as 'views' from drugs INNER JOIN drug_seen on drugs.id = drug_seen.drug_id GROUP BY drugs.id order by views ASC
And now I am trying to write in in the Laravel equolent but I am facing some troubles.
This is what I have tried
$drugs = Drug::select(DB::raw('drugs.*,count(*) as views'))
->join('drug_seen', 'drugs.id', 'drug_seen.drug.id')
->groupBy('drug.id')->orderByRaw('views');
I am having errors like column not found i think the code is not written properly
Drug class
class Drug extends Model
{
use HasFactory;
use SoftDeletes;
...
...
...
public function drugVisits()
{
return $this->hasMany(DrugSeen::class);
}

Answer 1

Hop this will solve your problem.
$drugs = Drug::with('drugVisits')->get();
$drugs->count(); //for total records in drugs table.

Answer 2

You have typo error in join instead on drug_id you use drug.id
Try this:
$drugs = Drug::select(DB::raw('drugs.*,count(*) as views'))
->join('drug_seen', 'drugs.id', 'drug_seen.drug_id')
->groupBy('drugs.id')->orderByRaw('views');
}

Answer 3

As soon as you use join() you're leaving Eloquent and entering Query\Builder, losing the benefits of Model configurations in the process. And with() eager-loads aren't the answer, if you're looking to filter the results by both tables. What you want is whereHas().
Also, as far as your grouping and count manipulation there, I think you're looking more for Collection handling than SQL groups.
$drugModel = app(Drugs::class);
$results = $drugModel->whereHas('drugVisits')->with('drugVisits')->get();
$organizedResults = $results
->groupBy($drugModel->getKey())
->sortyBy(function (Drugs $drugRecord) {
return $drugRecord->drugVisits->count();
});
If you want to have a 'views' property that carries the count in the root-level element, it would look like this:
$drugModel = app(Drugs::class);
$results = $drugModel->whereHas('drugVisits')->with('drugVisits')->get();
$organizedResults = $results
->groupBy($drugModel->getKey())
->map(function (Drugs $drugRecord) {
$drugRecord->views = $drugRecord->drugVisits->count();
return $drugRecord;
});
->sortyBy('views');
