This Nova Package allow you to nest items in hierarchy level.
composer require aiman/nest-tool
class CreateTopicsTable extends Migration
{
/**
* Run the migrations.
*
* @return void
*/
public function up()
{
Schema::create('topics', function (Blueprint $table) {
$table->id();
$table->text('topic');
$table->text('slug')->nullable();
$table->integer('order')->default(1);
$table->integer('parent_id')->nullable();
$table->timestamps();
$table->softDeletes();
});
}
/**
* Reverse the migrations.

* @return void
*/
public function down()
{
Schema::dropIfExists('topics');
}
}
In order to use the nest tool, it requires a model to use which includes a order column, parent column, amd the display name to be shown in each item. Example is shown above
use Aiman\ThaanaTextField\ThaanaTextField;
/**
* Get the fields displayed by the resource.
*
* @param \Illuminate\Http\Request $request
* @return array
*/
public function fields(Request $request)
{
return [
ID::make()->sortable(),
//other fields
NestTool::make()
->usingModel(\App\Models\Topic::class)
->slug('slug')
->orderColumn('order')
->parentColumn('parent_id')
->displayName('topic')
->disable(false)
];
}
the model which is entered into usingModel() function should have this relationship
function parent(){
return $this->belongsTo('App\Models\Topic', 'parent_id');
}
function children(){
return $this->hasMany(self::class, 'parent_id')->orderBy('order')->with('children');
}
This function requires the model in which nest tool uses
NestTool::make()->usingModel(\App\Models\Topic::class)
This function requires the slug field to be displayed. By default it is slug
NestTool::make()->slug('slug')
This function requires the order column name in the model class above which is used for ordering. By default it is order
NestTool::make()->orderColumn('order')
This function requires the parent column name in the model class above which is used for nesting items under a parent item. By default it is parent_id
NestTool::make()->parentColumn('parent_id')
This function requires the display name's column name in the model class above which is used to display in each item. By default it is topic
NestTool::make()->displayName('topic')
