How to make order by in eager load laravel eloquent - php

Question

I wanna question about how to use order by inside eager load laravel eloquent, I already have a query like this :
$getData = StockIn::select(
StockIn::raw('group_concat(stock_ins.id_stock_in) as id_stock_ins'),
'stock_in_id_type'
)
->with(['type_of_items' => function ($query) {
$query->orderBy('type_of_item');
}])
->orderBy('type_of_items.type_of_item')
->groupBy('stock_ins.stock_in_id_type')
->get();
But when I compile the query and look to the result, the result of my query didn't make result with order by query, Am I making a mistake in my query so that the result is matching with my expectation? Thanks before
Here for my model :
Stock In :
public function type_of_items() {
return $this->belongsTo('App\TypeOfitem', 'stock_in_id_type');
}
Type Of Item :
public function stock_ins() {
return $this->hasMany('App\StockIn');
}
when I try to look on the console, the result of my query like this :
SQLSTATE[42S22]: Column not found: 1054 Unknown column 'type_of_items.type_of_item' in 'order clause' (SQL: select group_concat(stock_ins.id_stock_in) as id_stock_ins, `stock_in_id_type` from `stock_ins` group by `stock_ins`.`stock_in_id_type` order by `type_of_items`.`type_of_item` asc)

Answer 1

You're currently using order by on eager loaded data.
Instead, you need to call it on the model itself.
$getData = StockIn::select(
StockIn::raw('group_concat(stock_ins.id_stock_in) as id_stock_ins'),
'stock_in_id_type'
)
->with(['type_of_items' => function ($query) {
$query->orderBy('type_of_item');
}])
->orderBy('type_of_items.type_of_item')
->groupBy('stock_ins.stock_in_id_type')
->get();
You can also try it out without groupBy first, to be sure you're getting the correct results
