Hi

I could not find how to add default items to a relationship repeater.

I the EditPage for TimesheetWeek I want to display 7 TimesheetDay even if they do not exist in database.

There is 2 tables: days that belongs to weeks.

class TimesheetWeek extends Model {
	protected $casts = [
		'first_day' => 'immutable_date',
	];
	public function days(): HasMany {
		return $this->hasMany( TimesheetDay::class, 'week_id','id' );
	}
}
class TimesheetDay extends Model
{
	protected $casts = [
		'day' => 'immutable_date',
		'hours' => 'json',
	];
	public function week(): BelongsTo
	{
		return $this->belongsTo( TimesheetWeek::class, 'week_id','id' );
	}
}

In the TimesheetWeekResource::form() there is :

        /** @var CarbonImmutable $first_day */
        $first_day = $form->getRecord()->first_day;

        return $form
            ->schema([
                Forms\Components\Fieldset::make('Week')
                    ->schema([
                        Forms\Components\Select::make('company_id')
                            ->relationship('company', 'name')
                            ->required(),
                        Forms\Components\DatePicker::make('first_day')
                            ->required(),
                    ]),
                Repeater::make('days')
                    ->relationship()
                    ->columnSpan(2)
                    ->schema([
                        Forms\Components\DatePicker::make('day')
                            ->required(),
                        Repeater::make('hours')
                            ->schema([
                                Forms\Components\Fieldset::make('Label')
                                    ->schema([
                                        TextInput::make('start')->required(),
                                        TextInput::make('end')->required(),
                                    ])
                            ])
                            ->grid(4)
                            // ->defaultItems(2), // only works on CreatePage.
                            ->default([
                                ['start' => '', 'end' => ''],
                                ['start' => '', 'end' => ''],
                                ['start' => '', 'end' => ''],
                            ])
                            ,
                    ])
                    //->defaultItems(7), // only works on CreatePage.
                    ->default([
                        ['day'=>$first_day],
                        ['day'=>$first_day->addDay(1)],
                        //new TimesheetDay(['day'=>$first_day]),
                        //new TimesheetDay(['day'=>$first_day->addDay(1)]),
                    ])
                    ,
            ]);

Every things work fine, excepted the days default 😥

Any idea ? I've seeked the Internet for hours around mutateRelationshipDataBeforeFillUsing, afterStateHydrated ... but could not find a working solution 😥

Thanks for your help 💌

yes, default only works on CreatePage.

Use formatStateUsing

Thanks 🙏 , I go to re-read the doc.

just to make it clear default() works fine with the nested field Repeater::make('hours'), I get 3 blocks with start end for each.

default() is not working only with the relationship Repeater::make('day').

Ok, thanks @leandrocfe 👍
I use afterStateHydrated() to add default data to Repeater::make('day') and remove the call to Repeater::make('hours')->default([...])
