Introducing Formengine - The New Formbuilder, try for FREE formengine.io.

I want to add a column to the model, but I do not want to add it to the database. What do I do?

We have created the Extension container functionality for that. To use this functionality you need to:

  1. Add the Extensions (or any other name) field of the nvarchar(max) type to the table.
  2. Add a column to the model and specify its name in the Extension container field.
  3. Add attributes with the Extension flag.

After that, all attributes with the Extension flag will be serialized and stored in the Extension container in the JSON format.

Please, note:

  • DWKit ORM fully supports such columns; however, you may encounter difficulties when directly accessing these fields through the database server.
  • This functionality works in MS SQL Server 2017+ and PostgreSQL 9.5+.
