Question

I have three relational table attached below.

https://drive.google.com/file/d/1q1kdURIwFXxHb2MgdRyBkE1e3DMug7r-/view?usp=sharing

I have also three separate models where defined relation among all of my table's.I can read the City Model's information from Country model using hasManyThrough() relation But cannot read the Country information from City model. I have tried to retrieve City model's using ``hasManyThrough``` but didn't get result (attached as commented country method ). Please read my model and it's relational method here..

Is there someone to help me for getting City model's information using Eloquent method hasManyThrough / hasManyThrough or using inverse of hasManyThrough / hasManyThrough ?

Answer 1

Why can't use parent method?

$city = City::find(1);
$country = $city->district->country();
