Datatables Bundle for Laravel 4

About

This bundle is created to handle the server-side processing of the DataTables Jquery Plugin (http://datatables.net) by using Eloquent ORM or Fluent Query Builder.

Feature Overview

Supporting Eloquent ORM and Fluent Query Builder
Adding or editing the contents of columns and removing columns
Templating new or current columns via Blade Template Engine
Customizable search in columns

Installation

Require bllim/datatables in composer.json and run composer update.

{
    "require": {
        "laravel/framework": "4.0.*",
        ...
        "bllim/datatables": "*"
    }
    ...
}

Composer will download the package. After the package is downloaded, open app/config/app.php and add the service provider and alias as below:

'providers' => array(
    ...
    'Bllim\Datatables\DatatablesServiceProvider',
),



'aliases' => array(
    ...
    'Datatables'      => 'Bllim\Datatables\Facade\Datatables',
),

Finally you need to publish a configuration file by running the following Artisan command.

$ php artisan config:publish bllim/datatables

Usage

It is very simple to use this bundle. Just create your own fluent query object or eloquent object without getting results (that means don't use get(), all() or similar methods) and give it to Datatables. You are free to use all Eloquent ORM and Fluent Query Builder features.

Some things you should know:

When you call the select method on Eloquent or Fluenty Query, you choose columns.
Modifying columns
- You can easily edit columns by using edit_column($column, $content)
- You can remove any column by using remove_column($column)
- You can add columns by using `add_column($column_name, $content, $order)
- You can use the Blade Template Engine in your $content values.
- You may pass a function as the $content to the add_column or edit_column calls. The function receives a single parameter: the query row/model record. (see Example 2)
The column identifiers are set by the returned array.
- That means, for posts.id the relevant identifier is id, and for owner.name as ownername it is ownername
You can set the "index" column (http://datatables.net/reference/api/row().index()) using set_index_column($name)
You can add class (DT_RowClass) to each row using set_row_class($content) function.
You can add jquery's data (DT_RowData) to each row using set_row_data($name,$content) function.
You can add customized search filters for each column to override the default search functionality
You can call make(true) to return an array of objects instead of an array of arrays. (see Example 4)

Examples

Example 1: Simple use

$posts = Post::select(array('posts.id','posts.name','posts.created_at','posts.status'));

return Datatables::of($posts)->make();

Example 2: Adding and editing columns

$place = Place::left_join('owner','places.author_id','=','owner.id')
   ->select(array('places.id','places.name','places.created_at','owner.name as ownername','places.status'));


return Datatables::of($place)
    ->add_column('operations', '<a href="{{ URL::route( \'admin.post\', array( \'edit\',$id )) }}">edit</a>
                    <a href="{{ URL::route( \'admin.post\', array( \'delete\',$id )) }}">delete</a>
                ')
    ->edit_column('status', '{{ $status ? 'Active' : 'Passive' }}')
    ->edit_column('ownername', function($row) {
        return "The author of this post is {$row->ownername}";
    })
    ->remove_column('id')
    ->make();

Notice: If you use double quotes while assigning the $content in an add_column or edit_column call, you should escape variables with a backslash (\) to prevent an error. For example:

edit_column('id', "{{ \$id }}") .

Example 3: Using filter_column

$clients = Client::select(array(
		'Client.id',
		DB::raw('CONCAT(Client.firstname," ",Client.lastname) as ClientName'),
		'Client.email',
		'Client.code',
		'Client.updated_at',
		'Client.isActive',
		'Language.name as LanguageName',
	))
	->leftJoin('Language', 'Client.Language_id', '=', 'Language.id')
	->where('isDeleted', '!=', '1');

return Datatables::of($clients)
		->filter_column('id', 'where', 'Client.id', '=', '$1')
		->filter_column('code', 'where', 'Client.code', '=', DB::raw('UPPER($1)'))
		->filter_column('LanguageName', 'whereIn', 'Language.name', function($value) { return explode(',',$value); })
		->filter_column('updated_at', 'whereBetween', 'Client.updated_at', function($value) { return explode(',',$value); }, 'and')
		->edit_column('isActive', '@if($isActive) <span class="label label-success">Active</span> @else <span class="label label-danger">Inactive</span> @endif')
		->make();

Notes on filter_column:

Usage: filter_column ( $column_name, $method, $param_1, $param_2, ..., $param_n )

$column_name - the column name that search filter is be applied to
$method - can be any of QueryBuilder methods (where, whereIn, whereBetween, having etc.).
- Note: For global search these methods are automaticaly converted to their "or" equivalents (if applicable, if not applicable, the column is not searched).
- If you do not want some column to be searchable in global search, set the last parameter to "and" (see line 17 in example above). Doing this, the filter cannot be switched into its "or" equivalent and therefore will not be searched in global search .
$param_1 ... $param_n - these are parameters that will be passed to the selected where function ($method). Possible types:
- string
- DB::raw() - The DB::raw() can output literaly everything into the query. For example, subqueries or branching if you need some really sophisticated wheres.
- function - or any other callable
- array of any of the above
The search value is passed to the query by the string $1 placed anywhere in parameters. If a callable (function) is used the searched value is passed to callable as first parameter the first parameter (again see line 17).
- The callable must return a value that will be passed to the QueryBuilder's function.

Example 4: Returning an array of objects

$posts = Post::select(array('posts.id','posts.name','posts.created_at','posts.status'));

return Datatables::of($posts)->make(true);

This returns a JSON array with data like below:

data: {
    {
        id: 12,
        name: 'Dummy Post',
        created_at: '1974-06-20 13:09:51'
        status: true
    }
    {
        id: 15,
        name: 'Test post please ignore',
        created_at: '1974-06-20 13:15:51',
        status: true
    }
}

Example 5: DT_RowID, DT_RowClass and DT_RowData

$todo = ToDoList::select(array('todo.id','todo.name','todo.created_at','todo.status'));

return Datatables::of($todo)
    ->set_index_column('id')
    ->set_row_class('@if($status=="done") success @endif')
    ->set_row_data('created_at','{{$created_at}}')
    ->make();

Example 6: Advanced usage of dataFullSupport

To better utilize dataTables mData (1.9), now columns.data (1.10) feature you may enable dataFullSupport by either setting it to true in the config file, or passing true to the second initialization argument Datatables::of($query, true)

Creating a table with a searchable and sortable joined table:

//html
<table id="user-list"></table>
//script.js
$("#users-list").dataTable({
        "processing": true,
        "serverSide": true,
        "ajax": "/api/user/datatables",
        "order": [[1,'desc']],
		"columnDefs": [ { //this prevents errors if the data is null
			"targets": "_all",
			"defaultContent": ""
		} ],
        "columns": [
            //title will auto-generate th columns
            { "data" : "id",               "title" : "Id", "orderable": true, "searchable": false },
            { "data" : "profile.last_name","title" : "Name", "orderable": true, "searchable": true },
            { "data" : "username",         "title" : "Username", "orderable": true, "searchable": true },
            { "data" : "email",            "title" : "Email", "orderable": true, "searchable": true },
            { "data" : "created_date",     "title" : "Created", "orderable": true, "searchable": true },
        ]
    });

$users = Models\User::select()->ModelJoin('profile');
        return $dataTables = Datatables::of($users)
            ->filter_column('profile.last_name','where',\DB::raw('CONCAT(profile.last_name,\' \',profile.first_name)'),'LIKE','$1')
            ->filter_column('created_at','where','users.created_at','LIKE','$1')
            //for the blade template only the array data results is provided, it is `extracted` into the template
            ->edit_column('profile.last_name', '{{ $profile["first_name"]." ".$profile["last_name"] }}')
            ->edit_column('created_at', function($result_obj) {
                //in a callback, the Eloquent object is returned so carbon may be used
                return $result_obj->created_at->format('d/m/Y - h:ia');
            })
            ->add_column('manage', '<a href="/user/edit/{{$id}}" >Edit</a>', 3)
            ->remove_column('profile.photo_id')
            ->set_index_column('row-{{ $id }}')
            ->make();

//helper scope method in base Model class
    public function scopeModelJoin($query, $relation_name, $operator = '=', $type = 'left', $where = false) {
        $relation = $this->$relation_name();
        $table = $relation->getRelated()->getTable();
        $one = $relation->getQualifiedParentKeyName();
        $two = $relation->getForeignKey();

        if (empty($query->columns)) {
            $query->select($this->getTable().".*");
        }

        //$join_alias = $table;
        $prefix = $query->getQuery()->getGrammar()->getTablePrefix();
        $join_alias = $relation_name;
        foreach (\Schema::getColumnListing($table) as $related_column) {
            $query->addSelect(\DB::raw("`$prefix$join_alias`.`$related_column` AS `$join_alias.$related_column`"));
        }
        $two = str_replace($table . ".", $join_alias . ".", $two);
        return $query->join("$table AS $prefix$relation_name", $one, $operator, $two, $type, $where); //->with($relation_name);
    }

Notes on columns.data:

When using the columns.data option the order the data is returned in doesn't matter.
You may return extra rows that you use in some tables, and ones you don't without needing to worry about ignoring them.
When the data is returned within enbeded arrays, datatables lets you access it using dot notation. This allows the columns.data element to address items in your table. The values of the data items are expected to match the columns (or aliases) of the table. For example, if you sort by "profile.last_name" it will use that to sort by the last_name column in the "profiles" table, so make sure that table is joined so the reference exists.
If you don't do a direct join you can't sort or search those columns so make sure to set those options to false in the columns array
If you eager load the data via Eloquent, you will still get those items back and they may be edit via edit_column just the same without needing to alias the names.
