Installation

You can install the package via composer:

Usage

use Gabrielesbaiz\NovaFieldJson\NovaFieldJson; 

  NovaFieldJson::make("ColumnName", [ 
      Select::make(__("Discount Type"), "type")
          ->options([
              'percent' => __('Percent'),
              'amount' => __('Amount'),
          ])->rules('required')->default('percent'),
      Number::make(__("Discount Value"), "value")
          ->rules("min:0")
          ->withMeta([
              'min' => 0
          ]),   
  ]),

Nested Usage

Storing nested data is very like straight data. just like the following; use the Json nested.

use Gabrielesbaiz\NovaFieldJson\NovaFieldJson; 

  NovaFieldJson::make("ColumnName", [ 
      Select::make(__("Discount Type"), "type")
          ->options([
              'percent' => __('Percent'),
              'amount' => __('Amount'),
          ])->rules('required')->default('percent'),
      Number::make(__("Discount Value"), "value")
          ->rules("min:0")
          ->withMeta([
              'min' => 0
          ]),   
      // nested data
      NovaFieldJson::make("discount", [ 
        Select::make(__("Discount Type"), "type")
            ->options([
                'percent' => __('Percent'),
                'amount' => __('Amount'),
            ])->rules('required')->default('percent'),
        Number::make(__("Discount Value"), "value")
            ->rules("min:0")
            ->withMeta([
                'min' => 0
            ]),   
      ]),
  ]),

Action Usage

It is possible to use the Json in the Action like follow:

use Gabrielesbaiz\NovaFieldJson\NovaFieldJson; 

class UpdateTime extends Action
{
    use InteractsWithQueue, Queueable, SerializesModels; 


    /**
     * Perform the action on the given models.
     *
     * @param  \Laravel\Nova\Fields\ActionFields  $fields
     * @param  \Illuminate\Support\Collection  $models
     * @return mixed
     */
    public function handle(ActionFields $fields, Collection $models)
    {
      //
    }

    /**
     * Get the fields available on the action.
     *
     * @return array
     */
    public function fields()
    {
        return collect([
            /// some fields
            
            NovaFieldJson::make(mb_strtolower($meal), [
                Text::make(__("From"), 'from')->rules('required'),
                Text::make(__("Until"), 'until')->rules('required'),  
                NovaFieldJson::make(mb_strtolower($meal), [
                    Text::make(__("From"), 'from'),
                    Text::make(__("Until"), 'until'),  
                ]),
            ]),

            /// some fields
        ])->map(function($field) {
            return $field instanceof NovaFieldJson ? $field->fields() : [$field];
        })->flatten()->all();
    }
}

Showing And Hiding Fields

you can use the field show/hide methods on the JSON field. so this method will be called on each field under the Json field.The following example will hide all fields from the index view.

use Gabrielesbaiz\NovaFieldJson\NovaFieldJson; 

  NovaFieldJson::make("ColumnName", [ 
       // fields
  ])->hideFromIndex(),

Save Last Values

By default; we clean the last data for store new data. but, it's possible to save the last data. for this, call the saveHistory method on parent Json class. this causes us to overwrite the new data without clean the last data. see the follow:

use Gabrielesbaiz\NovaFieldJson\NovaFieldJson; 
  
  NovaFieldJson::make("ColumnName", [ 
       // fields
  ])->saveHistory(),

Separated Data

If you want store fields in one column but show in a separate place; you should make multiple Json field by one name.see the following:

use Gabrielesbaiz\NovaFieldJson\NovaFieldJson; 

  NovaFieldJson::make("ColumnName", [ 
       // fields group 1
  ]),

  // other fields

  NovaFieldJson::make("ColumnName", [ 
       // fields group 2
  ])->saveHistory(),

• ATTENTION: at this situation, you should use saveHistory for next Json field.

Fill The Value

if you want to store the customized value of the field; you can use the fillUsing method and return custom value. see the follow:

• fillUsing accept three argumnets $request, $attribute, $requestAttribute.

use Gabrielesbaiz\NovaFieldJson\NovaFieldJson; 
  
  NovaFieldJson::make("ColumnName", [ 
       Number::make(__("Discount Value"), "value")
            ->rules("min:0")
            ->withMeta([
                'min' => 0
            ])->fillUsing(function($request, $attribute, $requestAttribute) {
                if($request->exists($requestAttribute)) { 
                    return $request[$requestAttribute];
                }

                return 1000;
            }), 
  ]),
  

Null Values

If there need to store some values as the null; you can use the nullable method that works like the Nova nullable. By default; nullable has the true value which means all values will be stored. But; It's possible to reject the storing of null values via passing the false value into the nullable method.

Auto Casting

If not defined JSON casting for the field attribute; we will convert the field Value into JSON. if you need disable this feature; use the ignoreCasting method;
