Refresh page data from resource form action

I need to call refreshFormData (https://filamentphp.com/docs/3.x/panels/pages#refreshing-form-data) from an action within a resource form, but that method is on the page. How can I access the page component from the action method?

Solution:

I managed to get this fully working with: ```php ->action(function (array $data, Forms\Components\Repeater $component) { Chapter::create($data, ...); $component->clearCachedExistingRecords();...

you can inject $livewire

Jack SleightOP•4w ago

Ah ha, thanks! I tried $page. Is there a list of everything that can be passed to those closures somewhere? That works, but refreshFormData doesn't seem to be doing anything. I'm trying to refresh a relationship (displayed as a repeater). Any ideas?

Perfect thanks

LeandroFerreira•4w ago

could you share the code please?

Jack SleightOP•4w ago

Sure. Just for context, I want to override the repeaters add action to use a modal that prompts for data and then actually creates the record. It all works perfectly, except I need the repeater to update with the newly added item.

Forms\Components\Repeater::make('chapters')
    ->relationship()
    ->label('Lessons')
    ->itemLabel(fn (array $state): ?string => $state['title'] ?? null)
    ->addActionAlignment(Alignment::Start)
    ->addAction(fn ($action) => $action
        ->form([
            Forms\Components\TextInput::make('title')
                ->required(),
        ])
        ->action(function (Page $livewire, Course $record, array $data) {
            Chapter::create([
                ...$data,
                'course_id' => $record->id,
            ]);
            $livewire->refreshFormData(['chapters']);
        }))

Forms\Components\Repeater::make('chapters')
    ->relationship()
    ->label('Lessons')
    ->itemLabel(fn (array $state): ?string => $state['title'] ?? null)
    ->addActionAlignment(Alignment::Start)
    ->addAction(fn ($action) => $action
        ->form([
            Forms\Components\TextInput::make('title')
                ->required(),
        ])
        ->action(function (Page $livewire, Course $record, array $data) {
            Chapter::create([
                ...$data,
                'course_id' => $record->id,
            ]);
            $livewire->refreshFormData(['chapters']);
        }))

try this please

Forms\Components\Repeater::make('chapters')
...
->registerListeners([
    'refreshChapters' => [
        function (Repeater $component, Course $record) {
            $component->state($record->chapters->toArray());
        },
    ],
])

Forms\Components\Repeater::make('chapters')
...
->registerListeners([
    'refreshChapters' => [
        function (Repeater $component, Course $record) {
            $component->state($record->chapters->toArray());
        },
    ],
])

Chapter::create([...]);
$livewire->dispatchFormEvent('refreshChapters', record: $record);

Chapter::create([...]);
$livewire->dispatchFormEvent('refreshChapters', record: $record);

That works, thanks! But, when you then hit save on the form it attempts to save the chapter again, which fails with a null title column error, and that somehow deletes the row that was previously added... do I need to tell it that item already exists somehow?

LeandroFerreira•4w ago

hum not sure. I think the correct approach would be to create/update the relationship items using the default submit page action

LeandroFerreira•4w ago

You can also use Relation Mangers to handle this.

Jack SleightOP•4w ago

Yeah I did try that, but I need the drag and drop re-ordering feature. May have to cook up a custom field.

LeandroFerreira•4w ago

There is a reorderable function in Filament tables that you can use. Yes, you can also create a custom field and manage it as you need.

Jack SleightOP•4w ago

Ah OK, thanks I'll check that out. It does get even more complicated, because each chapter then has a list of lessons, and ideally I want to end up with a single view where you can add/edit/delete/reorder chapters and lessons 😂 In theory repeater works great for this, I've got the add/edit/delete/reorder working great, it's just syncing the data after the actions that's the issue.

I managed to get this fully working with:

->action(function (array $data, Forms\Components\Repeater $component) {
    Chapter::create($data, ...);
    $component->clearCachedExistingRecords();
    $component->fillFromRelationship();
})

->action(function (array $data, Forms\Components\Repeater $component) {
    Chapter::create($data, ...);
    $component->clearCachedExistingRecords();
    $component->fillFromRelationship();
})

Thanks again for your help!

LeandroFerreira•4w ago

much better 👌

Jack SleightOP•4w ago

And it works perfectly on the nested repeaters as well.
