在where子句中指定表时的Eloquent错误

Question

I have this query:

$query = Product::query();

$query->join('models AS m', 'products.model_id', '=', 'm.id');

if ($request->has('q')) {
    $terms = explode(' ', $request->get('q'));
    $query->orWhereHas('products.name', function($q) use ($terms) { $q->whereIn('name', $terms); });
}

It's returning

Call to undefined method Illuminate\Database\Query\Builder::products()

If I change products.category to anything else the error change to the new value for example:

$query->orWhereHas('s.name', function($q) use ($terms) { $q->whereIn('name', $terms); });

Will output

Call to undefined method Illuminate\Database\Query\Builder::s()

I need to specify that category belongs to names because if I don't it returns ambiguous fields existence.

The reason I'm joining the models table is because I need to select a single field from model

$query->get(['products.id', 'products.name', 'products.front_image', 'products.back_image', 'products.slug', 'm.slug as model_slug'])

How can I specify table in where clause without getting this error?

Answer 1

The whereHas method is for querying relations; the first argument should correspond with the name of a relationship method in your Model. In your case, the QueryBuilder is trying to call the method products() on the Product model.

If you're looking to query records by name, you can just use the where() method.
