unique_with on update always says combination exists (2.0.1 )

[eduardogoncalves]

In my ProductRequest.php I have set this:

public function rules()
    {
        return [
            'name' => 'required|min:3|unique_with:products,category_id',
            'price' =>'required'
        ];
    }

And in my ProductsController.php I have this:

public function update(Product $product, ProductRequest $request)
    {
        $product->update($request->all());
        return redirect('products');
    }

But when I try to Update a field, like product's price, it gives me the message:

This combination of name, category id already exists.

Could someone help me?

Define a separate ProductUpdateRequest.php:

public function rules()
{
    return [
        'name' => 'required|min:3,
        'price' =>'required'
    ];
}

It would also be possible to specify one ID that should be ignored, but I think this is not possible with Laravel 5 Request objects.

Hi, I was playing with Request class, printing value of $this and this is what I've got:

public function rules()
    {
        switch($this->method())
        {
            case 'POST':
            {
                return [
                    'name' => 'required|min:3|unique_with:products,category_id',
                    'price' =>'required'
                ];
            }
            case 'PATCH':
            {
                return [
                    'name' => 'required|min:3|unique_with:products,category_id,'.$this->products->id,
                    'price' =>'required'
                ];
            }
        }
