Laravel Filterable

This package allows you to easily handle database filtering through query strings. The idea is taken from one of the Jeffrey's videos (behind the paywall). One quick example might look like this: /users?filter-username=~joe will result in SQL query select * from users where "username" like '%joe%'.

Installation

You can install the package via composer:

Laravel will discover the package by itself. If you feel old-school, disable auto-discovery and add Kyslik\LaravelFilterable\FilterableServiceProvider::class to the providers array in your config/app.php.

Before we start

Package lets us create & apply two kinds of filters: custom and generic.

Custom filters

Custom filters are just like in Jeffrey's video. We define our logic on builder instance and package will apply it via local scope.
Let's say we want to display recently created records. We create method recent($minutes = null) inside our filter class, this method returns Builder instance:

Full example is shown later on.

Generic filters

Generic filters are those defined in config file. By default, the package supports filtering timestamps, ranges, ins, booleans and strings.

Default operator matrix for generic filters

Usage

While using both custom or generic filters we must:

1. have local scope on model with signature scopeFilter(Builder $query, FILTERNAME $filters)
2. have particular (FILTERNAME) filter class that extends one of:
   • Kyslik\LaravelFilterable\GenericFilterable class - enables us to use both custom & generic filters
   • Kyslik\LaravelFilterable\Filterable class - enables us to use only custom filters
3. call scope within a controller

Example with custom filters

Let's say we want to use filterable on user model. We will have to create filter class App/Filters/UserFilter.php, specify filterMap() and method with our custom logic.

Note: filterMap() must be defined and it should return associative array where key is method name and value is either alias or array of aliases

Secondly, we will have to add a local scope to our user model via trait:

Finally, in user controller we will have to call model's scope:

Now we can visit users?recent or users?recently or users?recent=25 and results will be filtered by recent() method defined in UserFilters class.

Example with generic filters

Let's say we want to use filterable on user model. We will have to create filter class App/Filters/UserFilter.php and specify $filterables.

Secondly, we will have to add a local scope to our user model via trait:

Finally, in our user controller we will have to call model's scope:

We are ready to filter user model.

Note: behind the scenes GenericFilterable class extends Filterable class, thus using GenericFilterable also enables us to apply custom filters defined within the filter class

Additional configuration

While using generic filters we may define which generics should be allowed. In our filter class we define settings() method in which we specify settings.
