If a relationship is hidden on a resource form does filament still try to submit it?

I have a resource form that when no relationship is set displays a select box but that changes to a section displaying the details once the relationship is set. The problem is when submitting the form I'm getting an error that a null value in the relation violates not-null constraint. Below is the section of the form

Forms\Components\Select::make('user_id')
    ->hidden(fn (Get $get) => !empty($get('user_id')))
    ->columnStart(1)
    ->columnSpan(2)
    ->label('Owner')
    ->options(User::all()->pluck('name', 'id'))
    ->searchable()
    ->live(),
Forms\Components\Section::make('Owner Information')
    ->hidden(fn (Get $get) => empty($get('user_id')))                    
    ->columnSpan(2)
    ->relationship('owner')
    ->schema([
        Forms\Components\Section::make('Basic Information')
            ->columns(2)
            ->schema([
                Forms\Components\TextInput::make('name')
                    ->label('Full Name')
                    ->columnSpan(2)
                    ->maxLength(255),
                Forms\Components\TextInput::make('phone')
                    ->tel()
                    ->maxLength(255),
                Forms\Components\TextInput::make('email')
                    ->email()
                    ->maxLength(255),
            ])
            ->reactive(),
        Forms\Components\Section::make('Social Media')
            ->columns(3)
            ->schema([
                Forms\Components\TextInput::make('line_id')
                    ->maxLength(255)
                    ->reactive(),
                Forms\Components\TextInput::make('facebook')
                    ->maxLength(255)
                    ->reactive(),
                Forms\Components\TextInput::make('whatsapp')
                    ->maxLength(255)
                    ->reactive(),
            ]),
    ])
    ->reactive(),

Forms\Components\Select::make('user_id')
    ->hidden(fn (Get $get) => !empty($get('user_id')))
    ->columnStart(1)
    ->columnSpan(2)
    ->label('Owner')
    ->options(User::all()->pluck('name', 'id'))
    ->searchable()
    ->live(),
Forms\Components\Section::make('Owner Information')
    ->hidden(fn (Get $get) => empty($get('user_id')))                    
    ->columnSpan(2)
    ->relationship('owner')
    ->schema([
        Forms\Components\Section::make('Basic Information')
            ->columns(2)
            ->schema([
                Forms\Components\TextInput::make('name')
                    ->label('Full Name')
                    ->columnSpan(2)
                    ->maxLength(255),
                Forms\Components\TextInput::make('phone')
                    ->tel()
                    ->maxLength(255),
                Forms\Components\TextInput::make('email')
                    ->email()
                    ->maxLength(255),
            ])
            ->reactive(),
        Forms\Components\Section::make('Social Media')
            ->columns(3)
            ->schema([
                Forms\Components\TextInput::make('line_id')
                    ->maxLength(255)
                    ->reactive(),
                Forms\Components\TextInput::make('facebook')
                    ->maxLength(255)
                    ->reactive(),
                Forms\Components\TextInput::make('whatsapp')
                    ->maxLength(255)
                    ->reactive(),
            ]),
    ])
    ->reactive(),

Solution:

mutating the form data didn't work but it got me looking at the docs which is when I discovered the ability to conditionally submit the relationship 🙂

You can try to dd the subitted data and check whats passing. Just add the method mutateFormDataBeforeCreate in the Create** in the resource folder. ```php // in Create(resource name).php EXAMPLE: CreatePage.php protected function mutateFormDataBeforeCreate(array $data): array { dd($data); } ``` You can check if is null and remove it from the data. Same can be done for Edit.
