Composite Key validation when saving a record

I have the following components on the form of relation manager class

    public function form(Form $form): Form
    {
        return $form
            ->schema([
                Forms\Components\Select::make('option_1_value')
                    ->relationship('option1', 'key')
                    ->required(),

                Forms\Components\Select::make('option_2_value')
                    ->relationship('option2', 'key')
                    ->required(),

                Forms\Components\Select::make('option_3_value')
                    ->relationship('option3', 'key')
                    ->required(),
            ]);
    }

    public function form(Form $form): Form
    {
        return $form
            ->schema([
                Forms\Components\Select::make('option_1_value')
                    ->relationship('option1', 'key')
                    ->required(),

                Forms\Components\Select::make('option_2_value')
                    ->relationship('option2', 'key')
                    ->required(),

                Forms\Components\Select::make('option_3_value')
                    ->relationship('option3', 'key')
                    ->required(),
            ]);
    }

How can I validate unique combination selection for the parent resource when saving the form?

Basically, the selection for option 1 / option 2 / option 3 needs to be unique for the parent relation any advice on this please? @awcodes any advice on this.

awcodes•12mo ago

maybe?

->unique(column: ['option_1_value', 'option_2_value', 'option_3_value'])

->unique(column: ['option_1_value', 'option_2_value', 'option_3_value'])

so do I add this rule to all the 3 fields?

public function form(Form $form): Form
{
  return $form
    ->schema([
        Forms\Components\Select::make('option_1_value')
            ->relationship('option1', 'key')
            ->unique(column: ['option_1_value', 'option_2_value', 'option_3_value'])
            ->required(),

        Forms\Components\Select::make('option_2_value')
            ->relationship('option2', 'key')
            ->unique(column: ['option_1_value', 'option_2_value', 'option_3_value'])
            ->required(),

        Forms\Components\Select::make('option_3_value')
            ->relationship('option3', 'key')
            ->unique(column: ['option_1_value', 'option_2_value', 'option_3_value'])
            ->required(),
    ]);
}

public function form(Form $form): Form
{
  return $form
    ->schema([
        Forms\Components\Select::make('option_1_value')
            ->relationship('option1', 'key')
            ->unique(column: ['option_1_value', 'option_2_value', 'option_3_value'])
            ->required(),

        Forms\Components\Select::make('option_2_value')
            ->relationship('option2', 'key')
            ->unique(column: ['option_1_value', 'option_2_value', 'option_3_value'])
            ->required(),

        Forms\Components\Select::make('option_3_value')
            ->relationship('option3', 'key')
            ->unique(column: ['option_1_value', 'option_2_value', 'option_3_value'])
            ->required(),
    ]);
}

don't know, haven't needed it. just try it. it is confusing though, not gonna lie you're trying to unique across tables though, so i'm not sure there is a good way to do this.

AbiOP•12mo ago

the problem with the above is, the uniqueness for the parent id isn't set the table has

parent_id,  option_1_value, option_2_value, option_3_value

parent_id,  option_1_value, option_2_value, option_3_value

these are the 4 columns and I am trying to find option value combination for the parent_id

1, 1,2,3
1, 2,1,3
1, 3,2,1
1, 1,3,2
1, 2,3,1
2, 1,2,3
....

1, 1,2,3
1, 2,1,3
1, 3,2,1
1, 1,3,2
1, 2,3,1
2, 1,2,3
....

yea, i'm understanding. You're probably going to have to do a custom rule for this. https://laraveldaily.com/post/laravel-unique-validation-multiple-columns

but it'll probably get fairly complicated with each 'option' being a separate relationship and table. as long as the query is correct it should work though.
