Laravel关系返回null

Question

I'm trying to fetch database data through a model relationship in Laravel. I've set up one model, like this:

<?php

use Illuminate\Auth\UserInterface;
use Illuminate\Auth\Reminders\RemindableInterface;

class Userskeywords extends Eloquent {

    public function relatedKeywords()
    {
        return $this->hasOne('Keywords', 'id', 'keywordId');
    }

}
?>

And the other model is just a normal model. In the database they look like this:

Keywords

UsersKeywords

However, when I run UsersKeywords::with('relatedKeywords')->get() it returns NULL for related_keywords . This happens when the following code is executed. What am I doing wrong?

$keywords = Userskeywords::where('user', '=', $id)->get();
$keywords->load('relatedKeywords');
return Response::json($keywords);

Answer 1

Your relation is called relatedKeywords so you need to access related object with

$object->relatedKeywords

instead of

$object->related_keywords
