I have three tables, an articles table, a tags table, and an intermediate pivot table called article_tags, which only contains an article_id and tag_id, forming a many-to-many-relationship.
I want to write a function that receives an Article, and returns a collection or query with all Articles that share at least one tag with the received Article, after trying a bunch of different solutions, I have this:
public function scopeRelated($query, Article $article)
{
return $query->whereHas('tags', function ($query) use ($article) {
// I've tried a bunch of different lines, like just $article->tags
$query->whereIn('tags', $article->tags->pluck('id'));
});
}
This returns an error:
Illuminate/Database/QueryException with message 'SQLSTATE[42S22]: Column not found: 1054 Unknown column 'tags' in 'where clause' (SQL: select * from articles
where exists (select * from tags
inner join article_tag
on tags
.id
= article_tag
.tag_id
where articles
.id
= article_tag
.article_id
and tags
in (1, 6, 4)))'
Evidently, Eloquent is trying to match the tags to a 'tags' column on the Articles table, which doesn't exist. What would be the correct way of asking for what I want?
