Question

I want show gallery with parent and child. I have code in controller to call model like this.

$galery  = GalleryModel::with(['gallerydetail'])->get();

And i have code for get table and column in model :

<?php
namespace App\Models;

use Illuminate\Database\Eloquent\Model;

class GalleryModel extends Model {
    protected $table        = 'tbl_gallery';
    protected $primary_key  = 'id_gallery';
    protected $fillable     = ['category_id','author_id','gallery_title','gallery_text','gallery_time','gallery_date','gallery_isdelete'];

    public function gallerydetail() {
        return $this->hasMany(GalleryDetail::class, 'gallery_id');
    }
}

class GalleryDetail extends Model {
    protected $table        = 'tbl_gallery_detail';
    protected $primaryKey   = 'id_detail_gallery';

You don't have to add second argument in hasMany in gallerydetail() function, just add belongsTo function in your GalleryDetail Model.

GalleryModel:

public function gallerydetail() {
    return $this->hasMany(GalleryDetail::class);
}

GalleryDetail:

public function gallerymodel() {
    return $this->belongsTo(GalleryModel::class, 'gallery_id');
}
