Make a model projectable

When you want to make your model projectable, you must add it the Projectable trait and define the $projections class attribute:

use App\Models\Projections\MyProjection;
use TimothePearce\TimeSeries\Projectable;

class MyProjectableModel extends Model
{
    use Projectable;

    protected array $projections = [
        MyProjection::class,
    ];
}

Implement a Projection

When you're implementing a projection, follow theses three steps:

• Define your projection periods
• Add a default content
• Bind your projection to the projectable models

Query a Projection

A Projection is an Eloquent model and is queried the same way, but keep in mind that the projections are all stored in a single table. That means you'll have to use scope methods to get the correct projections regarding the period you defined earlier:

MyProjection::period('1 day')
    ->between(
        today()->subDay(), // start date
        today(), // end date
    )
    ->get();

Query a time series

To get a time series from a projection model, use the toTimeSeries method:

MyProjection::period('1 day')
    ->toTimeSeries(
        today()->subDay(),
        today(),
    );

Note that this method fill the missing projections between the given dates with the default content you defined earlier.
