Product Variant info in ver 2.6

Hello,

how can I ad a field in to product variant info.

I need to ad product variant info. i.e. I would like to add "condition" and options new, used. It should show next to the price on product page. I dont want to ad it in specification or product attributes because I want to show it to next to the price.

do it in css. just press f12 ( developer tools) in ie./chrome or any other browser supperted. select the field you want to reposition. do changes in the margin values. and update the same in your style.css file in your theme/yourtheme/content/style.css file. you can achive it.  :)

Let me rephrase my question. I need a field in "product variant info" in admin area with options. The field name would be "condition" just like we have tax category. So I can put the condition of the item there and I want this to be displayed next to the price on product page.

I hope I was able to explain my question properly.

Any suggestion.

Thanks.

Check release notes for v2.6:
•Developers. Added generic attribute support (now you can add a new property to any entity without database changes). Previously we could do it only for "Customer" entity (we had "CustomerAttribute" associated entity). Now we have "GenericAttribute" and "IGenericAttributeService".

How do I change or add generic attributes? Can you please show me or explain me little bit.

Thanks

Here is how to extend tables using Generic Attributes. I have used it to extend Product as an example.

Generic Attribute Schema:

Column  Type
Id           int
EntityId   int
KeyGroup   nvarchar
Key           nvarchar
Value   nvarchar

Sample Data:
Id  EntityId  KeyGroup           Key                      Value
1  1          Customer           FirstName               Hari
2  1          Customer           LastName               Dupati
32  54845  ProductVariant   Barcode               111
33  54845  ProductVariant   YearToDateSales    222

Usage:

1.  Create SystemProductAttributeNames class under Nop.Core.Domain.Catalog Namespace

namespace Nop.Core.Domain.Catalog
{
    public partial class SystemProductAttributeNames
    {
        public static string Barcode { get { return "Barcode"; } }

        public static string YearToDateSales { get { return "YearToDateSales"; } }

    }
}

2. Inserting or Updating Attributes for an Entity.
                        

  _genericAttributeService = EngineContext.Current.Resolve<IGenericAttributeService>();

/// create an instance of productVariant

_genericAttributeService.SaveAttribute(productVariant, SystemProductAttributeNames.Barcode, "111");
 
_genericAttributeService.SaveAttribute(productVariant, SystemProductAttributeNames.YearToDateSales, "222");

3.Retreiving Attribute value based on Keygroup,Entity and Key using GenericAttributeServiceExtensions


string barcode = productVariant.GetAttribute<string>(SystemProductAttributeNames.Barcode);
decimal yeartodatesales = productVariant.GetAttribute<decimal>(SystemProductAttributeNames.YearToDateSales);
