How to add undo functionality with SubSonic

How I can add undo functionality with SubSonic?

Best Answer

You're not going to get many answers with this. Undo functionality is very costly and complex to implement. I think Rob toyed around with adding automatic undo functionality in (based on parallel tables with names set by convention), but I don't think that went anywhere. He's been spending his time on bringing SubSonic into linq-land and T4-ville.

If you're looking for an ORM/data object framework that has undo baked in, you'll probably want to check out CSLA.NET. It is, no surprise, a heavy duty framework which will probably require some heavy lifting to get it into your application. You'll have to do some of the database work SubSonic does for you, no matter what.

Getting back a collection of departments which each contain a collection of divisions would be ideal

SubSonic does this for you (if you setup your relationships correctly in the database), just select all Departments:

var depts = Model.Department.All();

There will be a property in each item of depts named Divisions, which contains a collection of Division objects.

You can use Take to select a limited number of items for example:

IQueryable<myTable> topFive = myTable.All()
  .OrderByDescending(table => table.reads)
  .Take(5);
