Get Relation data in Search results about laravel-boilerplate HOT 12 CLOSED

Ha just re-looked quickly your code and finded why your parent was null, i didnt see it.

You're simply forget to add parent_id in your sql fields so we should have :

return $requestSearchQuery->result([
            'product_categories.id',
            'product_categories.name',
            'product_categories.parent_id',
            'product_categories.slug',
            'product_categories.status',
            'product_categories.created_at',
            'product_categories.updated_at',
        ]);

The related ids is mandatory for getting "with relation" working ;)

You must explicit the property of the parent you want get in the results. Example :

return $requestSearchQuery->result([
            'product_categories.id',
            'product_categories.name',
            'parent.name',
            'product_categories.slug',
            'product_categories.status',
            'product_categories.created_at',
            'product_categories.updated_at',
        ]);

Hello,

I'm pretty sure this because you use a query SQL join on search method, so "$with" property cant apply in this case.
Just add manually a query join with his parent and it should work.

Thanks @adr1enbe4udou1n

I thoight so but I tried to put this in search function:

$query->leftJoin('product_categories', 'product_categories.id', '=', 'parent_id');

but I got :

"SQLSTATE[42000]: Syntax error or access violation: 1066 Not unique table/alias: 'product_categories' (SQL: select count(*) as aggregate from product_categories left join product_categories on product_categories.id = parent_id)

    public function search(Request $request)
    {

        /** @var Builder $query */
        $query = $this->productCategories->query();

        if (! Gate::check('view product_categories')) {
            // Filter to only current user's posts
            $query->whereUserId(auth()->id());
        }

        $query
            ->leftJoin('product_categories', 'product_categories.id', '=', 'parent_id');


        /** @var RequestSearchQuery $requestSearchQuery */
        $requestSearchQuery = new RequestSearchQuery($request, $query, [
            'name',
            'summary',
            'body',
        ]);

        if ($request->get('exportData')) {
            return $requestSearchQuery->export([
                'name',
                'status',
                'product_categories.created_at',
                'product_categories.updated_at',
            ],
                [
                    __('validation.attributes.title'),
                    __('validation.attributes.status'),
                    __('labels.created_at'),
                    __('labels.updated_at'),
                ],
                'product_categories');
        }


        return $requestSearchQuery->result([
            'product_categories.id',
            'product_categories.name',
            'product_categories.slug',

            'product_categories.created_at',
            'product_categories.updated_at',
        ]);

It's because you join with the same table with same alias.
Try with a different alias :

Getting there :
I done this

$query ->leftJoin('product_categories as parent', 'parent.id', '=', 'product_categories.parent_id');

but in the response 'parent' value is still null

Do i need to modify search function somehow as I think it somehow needs to be included in response.

??

Perfect that worked.. 👍

But how come you could get 'owner' object in PostController->search() but in this case I have to be granular ?

Ideally I would like to get the whole object in the search result

Ha in fact i get this owner thanks to "$with" property.

For posts I use users join only for make order by working.
So indeed strange it's not working on your side, maybe a particular case as it's the same table/object ?

Thanks , that worked perfect !!! :)

@webdesign7 He used Eager loading. You can check in laravel docs also. You can also do it bro .And I guess you are duplicating lot of things why don't you abstract some of code to methods

Thanks

@bloggervista for me personally wasn't too obvious the solution to that issue, being new to Laravel its normal I think for questions like that to come up.. especially on CMSes done by other developers.

Don't worry keep learning :)
