So I'm trying to add a new Metric Trend to a Resource but always receive the following error:
Too few arguments to function Laravel\Nova\Resource::__construct(), 0 passed in /crm/nova/src/Metrics/Trend.php on line 116 and exactly 1 expected {"userId":1,"exception":"[object] (Symfony\\Component\\Debug\\Exception\\FatalThrowableError(code: 0): Too few arguments to function Laravel\\Nova\\Resource::__construct(), 0 passed in crm/nova/src/Metrics/Trend.php on line 116 and exactly 1 expected at /crm/nova/src/Resource.php:108)
I'm trying to receive the data from the column 'ph_value' in the database table 'reports'.
<?php
namespace App\Nova\Metrics;
use Illuminate\Http\Request;
use Laravel\Nova\Metrics\Trend;
use App\Nova\Report;
class ph extends Trend
{
/**
* Calculate the value of the metric.
*
* @param \Illuminate\Http\Request $request
* @return mixed
*/
public function calculate(Request $request)
{
return $this->countByDays($request, Report::class, 'ph_value');
}
/**
* Get the ranges available for the metric.
*
* @return array
*/
public function ranges()
{
return [
30 => '30 Days',
60 => '60 Days',
90 => '90 Days',
];
}
/**
* Determine for how many minutes the metric should be cached.
*
* @return \DateTimeInterface|\DateInterval|float|int
*/
public function cacheFor()
{
// return now()->addMinutes(5);
}
/**
* Get the URI key for the metric.
*
* @return string
*/
public function uriKey()
{
return 'ph';
}
}
Card is of course included.
public function cards(Request $request)
{
return [
new Metrics\Ph,
];
}
The trend metric just loads constantly like it isn't available to retrieve the data.
countByDays
function's second parameter is a model
class not Nova resource
class.
Update following use statement use App\Nova\Report
to use App\Report
I have same issue, just change use App\Nova\Report; to use App\Report; and it'll be fine. Suggestion from php storm so weird xD
