I struggled with this lately. What we seek is a BelongsToThrough relationship field. That type of relationship isn't natively supported by Laravel, which means there's no field for it in Nova either. However, you can easily implement it in Laravel by installing this package: https://github.com/staudenmeir/belongs-to-through
You can then add your report relationship to the User model.
// App\Models\Report
use \Znck\Eloquent\Traits\BelongsToThrough;
public function report()
{
return $this->belongsToThrough('App\Models\User','App\Models\Meter');
}
And you can use a regular BelongsTo relationship within Nova.
// App\Nova\Report
public function fields(Request $request)
{
return [
BelongsTo::make('User')
]
}
Note: This would work for the Report index/details views, but you'll want to exclude it from the edit form. (Consider a computed Text field, if you want to display the user on the edit form.)
