How to select columns from joined tables: laravel eloquent
Finally found it..
In the ->get()
you have to put the 'staff_id' like this
Vehicle::where('id',1)
->with(['staff'=> function($query){
// selecting fields from staff table
$query->select(['staff.id','staff.name']);
}])
->get(['id','name','staff_id']);
Since I didn't take the staff_id
, it couldn't perform the join and hence staff table fields were not shown.
You can use normal join like this:
Vehicle::join('staff','vehicles.staff_id','staff.id')
->select(
'vehicles.id',
'vehicles.name',
'staff.id as staff_id',
'staff.name'
)
->get();
Since, you can't take both id
at once in a join because only one is allowed. So, you can staff's id as staff_id
.
You can add vehicle id condition with where clause like:
Vehicle::join('staff','vehicles.staff_id','staff.id')
->where('vehicle.id',1)
->select(
'vehicles.id',
'vehicles.name',
'staff.id as staff_id',
'staff.name'
)
->get();
Hope you understand.
The shortest and more convenient way I guess would be :
Vehicle::select('id','name','staff_id')->where('id',1)
->with('staff:id,name' )->get();
foreign key should present for selection .
Since Laravel 5.7 you can use with() like this :
with('staff:id,name' )
for granular selection.
