use QueryScope in Blade template

问题:

I have define scope in model like this

class Station extends Model {

    protected $primaryKey = 'st_id';

    public function scopeByDid($query)
    {
        return $query->groupBy("st_did");
    }

}

I can call byDid from controller but I cannot get it through blade template like this

@foreach ($river->stations->byDid as $didType)
....
@endforeach

how do I get it. Appreciate your response. Thanks

If you're getting a relationship as an attribute (without () at the end) it means the relationship will have already been retrieved before the scope.

To get your code to work you will just need to change your foreach to:

@foreach($river->stations()->byDid()->get() as $didType)

Hope this helps!
