Why is selection not working in laravel?

Question

Laravel

The News entity has a source_id field (owned by companies)
In Company

public function news()
    {
        return $this->hasMany('App\News', 'source_id', 'id');
    }

So Argument 2 passed to Illuminate\Database\Eloquent\Relations\ HasMany
::match() must be an instance of Illuminate\Database\Eloquent\Collection, instance of App\CustomCollection\SupportsCollection given, called in
What's wrong?

Answer 1

What is App\CustomCollection\SupportsCollection?
Direct text is written that the wrong type of a collection is transferred.
What is App\CustomCollection\SupportsCollection and where does it come from?

Answer 2

First of all, they most likely mixed up the order of the passed parameters: the
first is foreign_key, the second is local_key.
Secondly, they could also confuse entities, judging by your words.

class News
public function company()
{
     return $this->hasMany('App\Company', 'id', 'source_id');
}

class Company
public function news()
{
     return $this->belongsTo('App\News');
}

Thirdly: it would be worthwhile to understand the relationship between your entities. Because your words only confuse. Describe the Company and News entities. For example: many/one Company may own many News, many News may belong to one/many Companies. Since it actually depends on this how to correctly describe relationships (relations) in models. I am sure that if you scribble yourself on a piece of paper in such a simple text, then it will become clearer to you what and where to prescribe, and how to write it correctly.
