Sitecore Data Importer – Media import from SQL

The module is developed by @maaakstiles and I really like it because it’s easy to extend/change to fit your requirements. The basic idea is very easy. It gets data from somewhere (Sitecore/CSV/SQL/MySQL). I played with the SQL part.

I would like to import files from another database and create a media item from it. To make it work I had to do 2 changes.

Make it to deal with byte[]

using System;
using System.Data;
using Sitecore.Data;
using Sitecore.Data.Items;
namespace Sitecore.SharedSource.DataImporter.Providers
{
public class CustomSqlDataMap : Sitecore.SharedSource.DataImporter.Providers.SqlDataMap
{
public CustomSqlDataMap(Database db, string connectionString, Item importItem)
: base(db, connectionString, importItem)
{}
protected override string GetFieldValue(object importRow, string fieldName)
{
var item = importRow as DataRow;
var f = item[fieldName];
// it was the missing area because the default solution calls the .ToString()
// and if it's byte[] then I get "System.Byte[]"
var bytes = f as byte[];
if (bytes != null)
{
return Convert.ToBase64String(bytes);
}
return (f != null) ? f.ToString() : string.Empty;
}
}
}

So now I have the byte array converted to string. This value is passed to the FillField method so now I need to change that to attach this stream to the media item.

using System;
using System.IO;
using Sitecore.Data.Items;
using Sitecore.Resources.Media;
using Sitecore.SharedSource.DataImporter.Mappings.Fields;
using Sitecore.SharedSource.DataImporter.Providers;
namespace Sitecore.SharedSource.DataImporter.Mappings.Fields
{
public class ToMedia : ToText
{
public ToMedia(Item i)
: base(i)
{}
public override void FillField(BaseDataMap map, ref Item newItem, string importValue)
{
var bytes = Convert.FromBase64String(importValue);
var media = MediaManager.GetMedia(newItem);
// here upload the picture as a .jpg
media.SetStream(new MemoryStream(bytes, false), "jpg");
// it's needed to make it editable after SetStream becauase it closes the edit context
if (!newItem.Editing.IsEditing)
{
newItem.Editing.BeginEdit();
}
}
}
}

Remaining step is create a new template for Field in Sitecore and use it. This video shows how you can do that:
