How replace join query with whereHas? - php

Question

I am using Laravel 5.6 and i have a standard query
Order::where('dict_statuses_id', 1)
->leftJoin('dict_statuses', 'dict_statuses_id', '=', 'dict_statuses.id')
->get();
So i have list of orders with details where status = 1 (new) after join table i see status as New or Complete. Is any way to change this query using whereHas ?
i tried use
Order::whereHas('status', function($q){
$q->where('dict_statuses_id', 1);
})->get();
But no results, in model Order i have
public function status()
{
return $this->hasMany('App\DictStatuses');
}
[Updated]
i have an error:
Column not found: 1054 Unknown column 'dict_statuses.orders_id'
in 'where clause' (SQL: select * from `orders` where exists
(select * from `dict_statuses` where `orders`.`id` = `dict_statuses`.`orders_id` and `dict_statuses_id` = 1)
and `orders`.`deleted_at` is null)
In my table i have table Orders where is field: dict_statuses_id
and table dict_statuses with fields: id, public_name
Why error is about dict_statuses.orders_id

Answer 1

Try Order::has('status')->get();

Answer 2

You can pass in variables to a relationship so you could potentially do.
public function status($id) {
return $this->hasMany(DictStatuses::class)->where('dict_statuses_id', $id);
}
Try defining the local key & foreign key.
$this->hasMany(DictStatuses::class, 'foreign_key', 'local_key');

Answer 3

I think your dict_statuses doesn't have a column called order_id.
Please include that column in your migration
then call
Order::whereHas('status', function($q){
$q->where('dict_statuses_id', 1);
})->get();
in your controller
or change the relation in Order model as
public function status(){
return $this->belongsTo('App\DictStatuses'):
}
