DataTable Console Commands

Introduction

Artisan is the command-line interface included with Laravel. It provides a number of helpful commands that can assist you while you build your application. To view a list of all available Artisan commands, you may use the list command:

php artisan list

Creating a DataTable service class

In this example, we will create a DataTable service class.

php artisan datatables:make Posts

This will create an PostsDataTable class on app\DataTables directory.

namespace App\DataTables;

use App\User;
use Yajra\Datatables\Services\DataTable;

class PostsDataTable extends DataTable
{
    /**
     * Build DataTable class.
     *
     * @return \Yajra\Datatables\Engines\BaseEngine
     */
    public function dataTable()
    {
        return $this->datatables
            ->eloquent($this->query())
            ->addColumn('action', 'path.to.action.view');
    }

    /**
     * Get the query object to be processed by dataTables.
     *
     * @return \Illuminate\Database\Eloquent\Builder|\Illuminate\Database\Query\Builder|\Illuminate\Support\Collection
     */
    public function query()
    {
        $query = User::query();

        return $this->applyScopes($query);
    }

    /**
     * Optional method if you want to use html builder.
     *
     * @return \Yajra\Datatables\Html\Builder
     */
    public function html()
    {
        return $this->builder()
                    ->columns($this->getColumns())
                    ->ajax('')
                    ->addAction(['width' => '80px'])
                    ->parameters($this->getBuilderParameters());
    }

    /**
     * Get columns.
     *
     * @return array
     */
    protected function getColumns()
    {
        return [
            'id',
            // add your columns
            'created_at',
            'updated_at',
        ];
    }

    /**
     * Get filename for export.
     *
     * @return string
     */
    protected function filename()
    {
        return 'posts_' . time();
    }
}

Model Option

In this example, we will pass a --model option to set the model to be used by our DataTable.

php artisan datatables:make Posts --model

This will generate a App\DataTables\PostsDataTable class that uses App\Post as the base model for our query. The exported filename will also be set to posts_(timestamp).

<?php

namespace App\DataTables;

use App\Post;
use Yajra\Datatables\Services\DataTable;

class PostsDataTable extends DataTable
{
    /**
     * Build DataTable class.
     *
     * @return \Yajra\Datatables\Engines\BaseEngine
     */
    public function dataTable()
    {
        return $this->datatables
            ->eloquent($this->query())
            ->addColumn('action', 'path.to.action.view');
    }

    /**
     * Get the query object to be processed by dataTables.
     *
     * @return \Illuminate\Database\Eloquent\Builder|\Illuminate\Database\Query\Builder|\Illuminate\Support\Collection
     */
    public function query()
    {
        $query = Post::query();

        return $this->applyScopes($query);
    }

    /**
     * Optional method if you want to use html builder.
     *
     * @return \Yajra\Datatables\Html\Builder
     */
    public function html()
    {
        return $this->builder()
                    ->columns($this->getColumns())
                    ->ajax('')
                    ->addAction(['width' => '80px'])
                    ->parameters($this->getBuilderParameters());
    }

    /**
     * Get columns.
     *
     * @return array
     */
    protected function getColumns()
    {
        return [
            'id',
            // add your columns
            'created_at',
            'updated_at',
        ];
    }

    /**
     * Get filename for export.
     *
     * @return string
     */
    protected function filename()
    {
        return 'posts_' . time();
    }
}

Creating a DataTable Scope service class

DataTable scope is class that we can use to limit our database search results based on the defined query scopes.

php artisan datatables:scope ActiveUser

This will create an ActiveUser class on app\DataTables\Scopes directory.

namespace App\DataTables\Scopes;

use Yajra\Datatables\Contracts\DataTableScopeContract;

class ActiveUser implements DataTableScopeContract
{
    /**
     * Apply a query scope.
     *
     * @param \Illuminate\Database\Query\Builder|\Illuminate\Database\Eloquent\Builder $query
     * @return mixed
     */
    public function apply($query)
    {
         return $query->where('active', true);
    }
}
