Chart with a param or Chart for a specific model

[diogogomeswww]

Hi,

I want to create a widget chart for a specific model in the show operation route.
I can easily add a section to show a widget.

But I can't find a way to send custom data to the chart.
I need to send a model_id or a model to the chart's controller.

Is that possible?

Thank you,
Diogo Gomes

Hello Diogo,

Thanks for posting the question. The standard chart widget does not pass any data to the chart controller. However, you can create a custom chart widget by copying the one shipped with our PRO package and modifying the code at the top:

@php
  $controller = new $widget['controller'];
  $controller->model_id = $widget['model_id'];
@endphp

The extra parameter can be passed when defining the widget:

Widget::add([ 
    'type' => 'chart',
    'controller' => \App\Http\Controllers\Admin\Charts\WeeklyUsersChartController::class,
    'model_id' => 10, // <-- can by anything
]);

Hope this helps. Feel free to post follow-up questions if you have any.

Thanks!

@phpfour Thank you very much for your help.

However I'm not able to get the model_id on the chart controller.
I'm able to set the property that I want on the view like you said.

But I'm not able to get that custom param on either controller methods: setup or data...

Can you please help me?

@phpfour I've managed to do it in the controller, but grabbing the param from the url.
A little bit hacky but it works and I don't need to create a custom widget, I can do all the logic on the chart's controller.

Please share if you know a better way of getting the param that I'm sending to the widget.
