you can use: belongsTo -> brand in product model and set in ProductResource under $form->schema something like this

Forms\Components\Select::make('brand_id')
                    ->label("Brand")
                    ->relationship('branch', 'name'),

Forms\Components\Select::make('brand_id')
                    ->label("Brand")
                    ->relationship('branch', 'name'),

and on productResource -> table->columns

            ->columns([
                Tables\Columns\TextColumn::make('brand.name')
                    ->label('brands')
                    ->sortable(),

            ->columns([
                Tables\Columns\TextColumn::make('brand.name')
                    ->label('brands')
                    ->sortable(),

this works if brand has a product id column, however if it doesnt it just says brand::product() doesn't exist or something like that.

Do you mean, product has a brand_id?

adnn•3mo ago

yeah brands table doesn't have anything, relating it to products but product has brand_id. I have a Brand resource, am trying to make it so I can click on a Brand and still list its product where brand_id = selected_id or something like that

Solution

php artisan make:filament-relation-manager BrandResource products name Brand Model

public function products(): HasMany
{
    return $this->hasMany(Product::class);
}

public function products(): HasMany
{
    return $this->hasMany(Product::class);
}

Product Model

public function brand(): BelongsTo
{
    return $this->belongsTo(Brand::class);
}

public function brand(): BelongsTo
{
    return $this->belongsTo(Brand::class);
}
