Nova Global Filter

This package allows you to emit any of your existing Laravel Nova filters to metrics or custom cards.

Installation

You can install the package in to a Laravel app that uses Nova via composer:

composer require nemrutco/nova-global-filter

Usage

In this example, we are registering few Metric Cards and the Global Filter with a Date filter as:

...
use Nemrutco\NovaGlobalFilter\NovaGlobalFilter;
use App\Nova\Filters\Date;

class Store extends Resource
{
  ...
  public function cards(Request $request)
  {
    return [
      new TotalSales // Value Metric

      new Orders, // Trend Metric

      new MostSoldProduct, // Partition Metric

      // NovaGlobalFilter
      new NovaGlobalFilter([
        new Date, // Date Filter
      ]),
    ];
  }
  ...
}

And now metric cards or any other cards optimized to listen GlobalFilter can be filtered by using GlobalFilterable trait and calling $this->globalFiltered($model,$filters) method.

globalFiltered($model, $filters = []) method expect $model and $filters parameters:

use Nemrutco\NovaGlobalFilter\GlobalFilterable;
use App\Nova\Filters\Date;
...

class UsersPerDay extends Trend
{
use GlobalFilterable;

  public function calculate(NovaRequest $request)
  {
    // Filter your model with existing filters
    $model = $this->globalFiltered(Store::class,[
      Date::class // DateFilter
    ]);

    // Do your thing with the filtered $model
    return $this->countByDays($request, $model);

  }
...
}

And that's it. Cards will be filtered based on passed filter value.

If you want to apply default value on initial request make sure you set default value in your filter as

...
// set default date
public function default()
{
    return Carbon::now();
}
...

To change layout from grid to inline

by default it's set to grid

...
new NovaGlobalFilter([
    // Filters
])->inline(),
...

To enable Reset button

...
new NovaGlobalFilter([
    // Filters
])->resettable(),
...

To add multiple Global Filters

...
new NovaGlobalFilter([
    // Filters
])->inline()->resettable(),

new NovaGlobalFilter([
    // Filters
])->onlyOnDetail(),
...

To listen Global Filter on any Custom Cards:

...
created() {
  Nova.$on("global-filter-changed", filter => {
    // Do your thing with the changed filter
    console.log(filter);
  });
},
...

To request all filter states from Global Filter on any Custom Cards:

...
  Nova.$emit("global-filter-request");
...

To request spesific filters state from Global Filter on any Custom Cards:

...
created() {
  Nova.$emit("global-filter-request", [
      "App\\Nova\\Filters\\DateFilter",
      "App\\Nova\\Filters\\CountryFilter"
  ]);
},
...

To receive filters state from Global Filter on any Custom Cards:

...
created() {
  Nova.$on("global-filter-response", filters => {
    // Do your thing with the filters
    console.log(filters);
  });
},
...

Good to know

• Basic functionality of this package is that it listens all the asigned filters. Once a value of a filter is changed, it emits as Nova.$on('global-filter-changed', [changed filter and value]). So any card that listens to this event will recieve the filter and its value.
• This package overwrites Nova's default Metric Cards to allow them to listen "global-filter-changed" event. Make sure there are no any conflicts with other pacages.
• This package currently does not support Index view filters to be synchronized. So filters in Global Filter will not trigger update at the filters in Filter Menu of your Index view.
• Reset button simply reloads the current page. There is nothing fancy going on behind the scenes.
• If you are willing to support this package, it will be great to get your issues, PRs and thoughts on Github. And dont forget to Star the package.
