Requirements

Installation

You can install the package via composer:

composer require mediconesystems/livewire-datatables

Optional

You don't need to, but if you like you can publish the config file and blade template assets:

php artisan vendor:publish

This will enable you to modify the blade views and apply your own styling, the datatables views will be published to resources/livewire/datatables. The config file contains the default time and date formats used throughout

• This can be useful if you're using Purge CSS on your project, to make sure all the livewire-datatables classes get included

Several of the built-in dynamic components use Alpine JS, so to remove flickers on page load, make sure you have

[x-cloak] {
    display: none;
}

somewhere in your CSS

Basic Usage

• Use the livewire-datatable component in your blade view, and pass in a model:

...

<livewire:datatable model="App\User" />

...

Template Syntax

• There are many ways to modify the table by passing additional properties into the component:

<livewire:datatable
    model="App\User"
    include="id, name, dob, created_at"
    dates="dob"
/>

Component Syntax

Create a livewire component that extends Mediconesystems\LivewireDatatables\LivewireDatatable

php artisan livewire:datatable foo --> 'app/Http/Livewire/Foo.php'

php artisan livewire:datatable tables.bar --> 'app/Http/Livewire/Tables/Bar.php'

Provide a datasource by declaring public property $model OR public method builder() that returns an instance of Illuminate\Database\Eloquent\Builder

php artisan livewire:datatable users-table --model=user --> 'app/Http/Livewire/UsersTable.php' with public $model = User::class

Declare a public method columns that returns an array containing one or more Mediconesystems\LivewireDatatables\Column

Columns

Columns can be built using any of the static methods below, and then their attributes assigned using fluent method chains. There are additional specific types of Column; NumberColumn, DateColumn, TimeColumn, using the correct one for your datatype will enable type-specific formatting and filtering:

class ComplexDemoTable extends LivewireDatatable
{

    public function builder()
    {
        return User::query();
    }

    public function columns()
    {
        return [
            NumberColumn::name('id')
                ->label('ID')
                ->linkTo('job', 6),

            BooleanColumn::name('email_verified_at')
                ->label('Email Verified')
                ->format()
                ->filterable(),

            Column::name('name')
                ->defaultSort('asc')
                ->searchable()
                ->filterable(),

            Column::name('planet.name')
                ->label('Planet')
                ->searchable()
                ->filterable($this->planets),

            DateColumn::name('dob')
                ->label('DOB')
                ->filterable()
                ->hide()
        ];
    }
}

Column Methods

Method Arguments Result Example static name String $column Builds a column from column definition, which can be eith Eloquent or SQL dot notation (see below) Column::name('name') static raw String $rawSqlStatement Builds a column from raw SQL statement. Must include "... AS alias" Column::raw("CONCAT(ROUND(DATEDIFF(NOW(), users.dob) / planets.orbital_period, 1) AS `Native Age`") static callback Array|String $columns, Closure|String $callback Passes the columns from the first argument into the callback to allow custom mutations. The callback can be a method on the table class, or inline (see below) static scope String $scope, String $alias Builds a column from a scope on the parent model Column::scope('selectLastLogin', 'Last Login') static delete [String $primaryKey default: 'id'] Adds a column with a delete button, which will call $this->model::destroy($primaryKey) Column::delete() static checkbox [String $column default: 'id'] Adds a column with a checkbox. The component public property $selected will contain an array of the named column from checked rows, Column::checkbox() label String $name Changes the display name of a column Column::name('id')->label('ID) format [String $format] Formats the column value according to type. Dates/times will use the default format or the argument Column::name('email_verified_at')->filterable(), hide

Marks column to start as hidden Column::name('id')->hidden() sortBy String|Expression $column Changes the query by which the column is sorted Column::name('dob')->sortBy('DATE_FORMAT(users.dob, "%m%d%Y")'), truncate [Integer $length (default: 16)]Truncates column to $length and provides full-text in a tooltip. Uses view('livewire-datatables::tooltip) Column::name('biography)->truncate(30)

linkTo String $model, [Integer $pad] Replaces the value with a link to "/$model/$value". Useful for ID columns. Optional zero-padding. Uses view('livewire-datatables::link) Column::name('id')->linkTo('user') round [Integer $precision (default: 0)] Rounds value to given precision Column::name('age')->round() defaultSort [String $direction (default: 'desc')] Marks the column as the default search column Column::name('name')->defaultSort('asc') searchable

Includes the column in the global search Column::name('name')->searchable() filterable [Array $options], [String $filterScope] Adds a filter to the column, according to Column type. If an array of options is passed it wil be used to populate a select input. If the column is a scope column then the name of the filter scope muyst also be passed Column::name('allegiance')->filterable(['Rebellion', 'Empire']) view String $viewName Passes the column value, whole row of values, and any additional parameters to a view template (see below) editable

Marks the column as editable (see below) alignCenter

Center-aligns column header and contents Column::delete()->alignCenter() alignCenter

Right-aligns column header and contents Column::delete()->alignRight() editable

Marks the column as editable (see below) excludeFromExport

Prevents the column as editable Column::name('email')->exclude

Listener

The component will listen for the refreshLivewireDatatable event, which allows you to refresh the table from external components.

Eloquent Column Names

Columns from Eloquent relations can be included using the normal eloquent dot notation, eg. planet.name, Livewire Datatables will automatically add the necessary table joins to include the column. If the relationship is of a 'many' type (HasMany, BelongsToMany, HasManyThrough) then Livewire Datatables will create an aggregated subquery (which is much more efficient than a join and group. Thanks @reinink). By default, the aggregate type will be count for a numeric column and group_concat for a string column, but this can be over-ridden using a colon delimeter;

NumberColumn::name('students.age:sum')->label('Student Sum'),

NumberColumn::name('students.age:avg')->label('Student Avg'),

NumberColumn::name('students.age:min')->label('Student Min'),

NumberColumn::name('students.age:max')->label('Student Max'),

Custom column names

It is still possible to take full control over your table, you can define a builder method using whatever query you like, using your own joins, groups whatever, and then name your columns using your normal SQL syntax:

public function builder()
{
    return User::query()
        ->leftJoin('planets', 'planets.id', 'users.planet_id')
        ->leftJoin('moons', 'moons.id', 'planets.moon_id')
        ->groupBy('users.id');
}

public function columns()
{
    return [
        NumberColumn::name('id')
            ->filterable(),

        Column::name('planets.name')
            ->label('Planet'),

        Column::raw('GROUP_CONCAT(planets.name SEPARATOR " | ") AS `Moon`'),

        ...
}

Callbacks

Callbacks give you the freedom to perform any mutations you like on the data before displaying in the table.

• The callbacks are performed on the paginated results of the database query, so shouldn't use a ton of memory
• Callbacks will receive the chosen columns as their arguments.
• Callbacks can be defined inline as below, or as public methods on the Datatable class, referenced by passing the name as a string as the second argument to the callback method.

class CallbackDemoTable extends LivewireDatatable
{
    public model = User::class

    public function columns()
    {
        return [
            Column::name('users.id'),

            Column::name('users.dob')->format(),

            Column::callback(['dob', 'signup_date'], function ($dob, $signupDate) {
                $age = $signupDate->diffInYears($dob);
                return $age > 18
                    ? '<span class="text-red-500">' . $age . '</span>'
                    : $age;
            }),

            ...
    }
}

Views

You can specify that a column's output is piped directly into a separate blade view template.

• Template is specified using ususal laravel view helper syntax
• Views will receive the column's value as $value, and the whole query row as $row

class CallbackDemoTable extends LivewireDatatable
{
    public model = User::class

    public function columns()
    {
        return [
            Column::name('users.id'),

            Column::name('users.dob')->view('tables.dateview'),

            Column::name('users.signup_date')->format(),
        ];
    }

'tables/dateview.blade.php'
<span class="mx-4 my-2 bg-pink-500">
    <x-date-thing :value="$value" />
</span>

Editable Columns

You can mark a column as editable using editable This uses the view() method above to pass the data into an Alpine/Livewire compnent that can directly update the underlying database data. Requires the column to have column defined using standard Laravel naming. This is included as an example. Much more comprehensive custom editable columns with validation etc can be built using the callback or view methods above.

class EditableTable extends LivewireDatatable
{

    public $model = User::class;

    public function columns()
    {
        return [
            Column::name('id')
                ->label('ID')
                ->linkTo('job', 6),

            Column::name('email')
                ->editable(),

            ...
        ];
    }
}

Styling

I know it's not cool to provide a package with tons of opionated markup and styling. Most other packages seem to have gone down the route of passing optional classes around as arguments or config variables. My take is that because this is just blade with tailwind, you can publish the templates and do whatever you like to them - it should be obvious where the Livewire and Alpine moving parts are.

You could also override the render method in your table's class to provide different templates for different tables.
