Setting table columns based on model's json column

I have this structure: Form Response a form has n responses, 1 response belongs to 1 form a form has a json field called fields - example:

[{"name": "birthdate", "type": "2", "is_required": true, "placeholder": "Random placeholder test"}]

[{"name": "birthdate", "type": "2", "is_required": true, "placeholder": "Random placeholder test"}]

a response has a field called responses - example:

{"birthdate": "2023-11-25"}

{"birthdate": "2023-11-25"}

in the form's responses table, i want to set the table's columns dynamically, so it shows all form fields and their responses. im trying this: (file app/Filament/Resources/ResponseResource.php)

public static function table(Table $table): Table
{
    return $table
        ->columns((function (): array {
            $form = Form::findOrFail(1); // 1 is set hardcoded on purpose to test

            return collect()
                ->merge($form->fields)
                ->map(function (array $field) {
                    return Tables\Columns\TextColumn::make($field['name'])
                        ->formatStateUsing(function (Response $record) use ($field) {
                            return $record->responses[str($field['name'])->slug()->toString()]; // this doesnt work ⚠️
                        })
                    ;
                })
                ->merge([
                    Tables\Columns\TextColumn::make('created_at'),
                    Tables\Columns\ToggleColumn::make('is_read')
                        ->onColor(Color::Green)
                        ->offColor(Color::Red)
                    ,
                ])
                ->toArray()
            ;
        })())

public static function table(Table $table): Table
{
    return $table
        ->columns((function (): array {
            $form = Form::findOrFail(1); // 1 is set hardcoded on purpose to test

            return collect()
                ->merge($form->fields)
                ->map(function (array $field) {
                    return Tables\Columns\TextColumn::make($field['name'])
                        ->formatStateUsing(function (Response $record) use ($field) {
                            return $record->responses[str($field['name'])->slug()->toString()]; // this doesnt work ⚠️
                        })
                    ;
                })
                ->merge([
                    Tables\Columns\TextColumn::make('created_at'),
                    Tables\Columns\ToggleColumn::make('is_read')
                        ->onColor(Color::Green)
                        ->offColor(Color::Red)
                    ,
                ])
                ->toArray()
            ;
        })())

which results into this image here, where the birthdate isnt shown. why??? if i just dd $record->responses[str($field['name'])->slug()->toString()] in my tinker, it works, it shows -> "2023-11-25"

if something is unclear, let me know please, so i can try to explain it better

Sergiu•7mo ago

have you tried dd() inside the ->formatStateUsing() ?

ericmp #2•7mo ago

yes, it doesnt dd but if i instead do it in here, when mergin the created_at field, it dds

Tables\Columns\TextColumn::make('created_at')
    ->formatStateUsing(function (Response $record) use ($field) {
        dd('hi'); // i see it in the browser
    })
,

Tables\Columns\TextColumn::make('created_at')
    ->formatStateUsing(function (Response $record) use ($field) {
        dd('hi'); // i see it in the browser
    })
,

Try using getStateUsing instead of formatStateUsing, it won't call if the column name does not exist on the base data 'birthdate' doesn't exist on $record so it won't even attempt to call the format function as there isn't really anything to format.

cant believe it works u think the code looks fine? or is kinda weird? i mean, u'd do it the way i did it? just looking for some feedback now ( : , if u dont mind

ConnorHowell•7mo ago

Nah I don't see anything inherently wrong with it, you could maybe store the slug as part of the fields def so you don't have to repeat this:

str($field['name'])->slug()->toString()

str($field['name'])->slug()->toString()

Just $field['slug'] or something
