Laravel Eloquent查询使用where

Question

I have two models. A status and a SaleDetails.

Status
------ 
  id
 name
 slug

I didn't define any relationship from Status to SaleDetails.

SaleDetails
-----------  
  id
  id_statuses //connects it to the status table
  id_products
  price
  qty

---

in the Model:

  public function status(){
    return $this->belongsTo('App\Status', 'id_statuses', 'id');
}

So what I am trying to do here is get all orders that whose status match a certain slug. E.g dd($this->sale_details->where('status.slug', 'pending')

With what I have using this:

$orders = $this->sale_details->with('product', 'status')->today()->get();

I should be able to filter them based on the status slugs in the frontend, but I want to just do it straight from here.

What's the best way to go about this?

Answer 1

You should use whereHas() it allows you to specify additional filters for the related model to check.

To apply the where condition you can use whereHas() like,

$status = "pending";

$this->sale_details->whereHas('status', function($q) use ($status){
   $q->where('slug', $status);
})->get();
