Laravel / Eloquent model with custom relations

Question

Imagine:

I have a adverts table with a price column. I have a pricerange table with a price_from and a price_to column.

I want to setup my Eloquent models, so that I can fetch the matching adverts from a Pricerange instance. Or query the pricerange table, and do a count on all matching adverts. Optionally, get the query from the adverts-relation and add more criteria.

In other words, I'd like the equivalent of this raw query:

SELECT priceranges.*, (
  SELECT COUNT(adverts.id) FROM adverts
  WHERE adverts.price >= priceranges.price_from 
  AND adverts.price < priceranges.price_to 
) AS adverts_count
FROM priceranges

or

SELECT priceranges.*, COUNT(adverts.id) AS adverts_count
FROM priceranges
INNER JOIN adverts ON adverts.price >= priceranges.price_from 
AND adverts.price < priceranges.price_to 
GROUP BY priceranges.id

Is this possible? I searched on custom relations, but I cannot find a working solution.

Thanks in advance!

Answer 1

You can do something like this,

Priceranges::join('adverts',function($join){
  $join->on('adverts.price','>=','priceranges.price_from')->orOn('adverts.price','<','priceranges.price_to');
})
->groupBy('priceranges.id')
->get();
