Refining ​

Overview ​

Refining is the concept of filtering and sorting data. Hybridly offers a first-party, declarative API for refining queries.

The refining process happens as follows:

  • The available filters and sorts are declared using a Refine instance
  • The Refine instance runs the query according to the current request
  • The query result and the refinements are shared to the view as properties
  • The view uses useRefinements to generate a user interface and apply sorts and filters

Experimental

This feature has not been dogfed yet and is considered experimental. Its API may change at any time. Feel free to give feedback on our Discord server.

Refining a query ​

The Refine class can be instanciated using a model class name or an Eloquent builder instance.

php
use App\Models\Chirp;
use Hybridly\Refining\Refine;

Refine::model(Chirp::class);
php
use App\Models\Chirp;
use Hybridly\Refining\Refine;

Refine::query(
  Chirp::query()->where('author_id', $user->id)
);

This Refine instance will update the query according to the specified refiners and the current request.

The query can then be executed as usual by chaining any Eloquent builder method, like paginate or get:

php
$chirps = Refine::model(Chirp::class)
  ->paginate();

Specifying refiners ​

A refiner is an object that updates the query according to the current request.

Filters and sorts are example of built-in refiners, but you may create your own by implementing the Hybridly\Refining\Contracts\Refiner interface.

You may specify refiners for a query using the with method:

php
use App\Models\Chirp;
use Hybridly\Refining\{Sorts, Filters};
use Hybridly\Refining\Refine;

$chirps = Refine::model(Chirp::class)->with([
    Sorts\Sort::make(property: 'created_at', alias: 'date'),
    Filters\TrashedFilter::make(name: 'trashed'),
]);

Sharing the query ​

The result of the query can be obtained by calling any valid Eloquent builder method on the Refine instance. Similarly, the available refiners can be obtained by calling the refinements method.

These two objects should be shared as properties to the view:

php
public function index()
{
    $this->authorize('viewAny', Chirp::class);

    $chirps = Refine::model(Chirp::class)->with([
        Sorts\Sort::make('created_at', alias: 'date'),
        Filters\TrashedFilter::make(),
    ])->forHomePage();

    return hybridly('chirps.index', [
        'chirps' => ChirpData::collection($chirps->paginate()),
        'refinements' => $chirps->refinements(),
    ]);
}
vue
<script setup lang="ts">
const $props = defineProps<{
	chirps: Paginator<App.Data.ChirpData>
	refinements: Refinements
}>()

const refine = useRefinements($props, 'refinements') 
</script>

Applying filters and sorts ​

The useRefinements composable may be used to build a user interface that allows applying refiners.

It provides methods that can be used to apply or reset filters and sorts, and it has properties that may enumerate available and current refiners.

The following example shows how to create a basic user interface using the filters properties:

vue
<script setup lang="ts">
const $props = defineProps<{
	chirps: Paginator<App.Data.ChirpData>
	refinements: Refinements
}>()

const refine = useRefinements($props, 'refinements') 
</script>

<template>
  <!-- Loops through available filters -->
  <div v-for="filter in refine.filters" :key="filter.name">

    <!-- Shows a `text` input for the filter named `body` -->
    <template v-if="filter.name === 'body'">
      <input
        type="text"
        @change="filter.apply($event.target.value)"
      />
    </template>

    <!-- Shows a `select` input for the "trashed" filter -->
    <template v-if="filter.type === 'trashed'">
      <select @change="filter.apply($event.target.value)">
        <option value="with" :selected="filter.value === 'with'">All</option>
        <option value="only" :selected="filter.value === 'only'">Trashed</option>
        <option value="" :selected="!filter.value">Not trashed</option>
      </select>
    </template>

  </div>
</template>

Querying nested relationships ​

Filters have basic relationship filtering capabilities, which means you may use the dot-notation syntax to specify a property from a relationship.

php
// ?filters[user]=jon
Filters\Filter::make('user.full_name', alias: 'user');

It is recommended to specify an alias when filtering relationship properties, otherwise the filter name will have its . replaced by underscores.

Note that filters using relationship use whereHas under the hood, which might not be the best option performance-wise.

Sorts are not supported

Note that the provided sorts do not support relationships. You will need to use a custom sort with a subquery to achieve a relationship sort.

Using an alias ​

It may not be desirable to expose the name of a database column to users. You may use the alias argument to specify a name that will identify a refiner:

php
// ?sort=date
Sorts\Sort::make('created_at', alias: 'date');

In the example above, date is used to apply the sort instead of the column name created_at.

Note that certain refiners, like TrashedFilter or CallbackFilter, cannot have an alias as they don't use the specified property in their query.

Available filters ​

Filter ​

This filter will use the provided column to find a match using a WHERE column = ? or a WHERE column LIKE ? statement.

Strict comparisons ​

By default, Filter will do a strict comparison using a WHERE column ? statement:

php
// ?filters[user_id]=1  ->  WHERE user_id = 1
Filters\Filter::make('user_id');

Loose comparisons ​

You may call the loose, beginsWithStrict or endsWithStrict methods to specify which kind of comparison the filter should use.

php
// ?filters[full_name]=Jon  ->  WHERE full_name LIKE %jon%
Filters\Filter::make('full_name')->loose();

// ?filters[full_name]=Jon  ->  WHERE full_name LIKE Jon%
Filters\Filter::make('full_name')->beginsWithStrict();

// ?filters[full_name]=Doe  ->  WHERE full_name LIKE %Doe
Filters\Filter::make('full_name')->endsWithStrict();

Using another operator ​

You may change the operator by specifying it through the operator method:

php
// ?filters[full_name]=Jon  ->  WHERE full_name NOT LIKE %jon%
Filters\Filter::make('full_name')
	->operator('NOT LIKE')
	->loose();

// ?filters[user_id]=1      ->  WHERE user_id != 1
Filters\Filter::make('user_id')->operator('!=');

Using an enum ​

You may call the enum method to specify a backed enum class that will validate the property. If the property doesn't match one of the enum values, the filter will not apply.

php
// ?filters[company]=apple   ->  Filter applies
Filters\Filter::make('company')->enum(Company::class);

// ?filters[company]=foobar  ->  Filter will not apply
Filters\Filter::make('company')->enum(Company::class);

SelectFilter ​

This filter will perform a where statement on the value provided by the options array. If the value is not found in the provided list, the filter will not apply.

Key-value options ​

If the options provided are a list of key-value pairs, the key represents the query parameter name, and the value for the column name:

php
// ?filters[os]=iphone -> `WHERE os = 'ios'`
Filters\SelectFilter::make('os', options: [
  'iphone' => 'ios',
  'ipad' => 'ipados',
  'samsung' => 'android',
]);

List options ​

If the option array is a list, the key will be used for both the query parameter and the column name:

php
// ?filters[os]=ios -> `WHERE os = 'ios'`
Filters\SelectFilter::make('os', options: [
  'ios',
  'ipados',
  'android',
]);

Enum options ​

Alternatively, you may provided a backed enum as the options.

php
use App\Enums\OperatingSystem;

// ?filters[os]=ios -> `WHERE os = 'ios'`
Filters\SelectFilter::make('os', OperatingSystem::class);

TrashedFilter ​

This filter will include or exclude soft-deleted records:

php
// ?filters[trashed]=only
Filters\TrashedFilter::make();

BooleanFilter ​

This filter will convert the request's value to a boolean value to perform a boolean where statement:

php
// ?filters[is_active]=true
// ?filters[is_active]=1
// ?filters[is_active]=y
Filters\BooleanFilter::make('is_active');

Available sorts ​

Sort ​

This sort will sort the records by the specified field:

php
// ?sort=created_at
Sorts\Sort::make('created_at');

Custom filters and sorts ​

The provided filters are relatively basic and will not suit every situation, notably the ones where relationships are involved.

You may use the provided CallbackFilter to implement your own filter using a closure or an invokable class:

php
// Invokable class
CallbackFilter::make('own_chirps', OwnChirpsFilter::class);

// Callback function
CallbackFilter::make(
	name: 'own_chirps',
	callback: function (Builder $builder, mixed $value, string $property) {
			$builder->where('author_id', auth()->id());
	}
);

Similary, the CallbackSort class can be used to implement a custom sort:

php
// Invokable class
CallbackSort::make('date', DateSort::class);

// Callback function
CallbackSort::make(
	name: 'date',
	callback: function (Builder $builder, string $direction, string $property) {
			$builder->orderBy('created_at', $direction);
	}
);
