Changes and improvements​

UniqueConstraint​

This Expanders version introduces a new Element UniqueConstraint. Each DataElement can have one or more of these UniqueConstraints.

Each one lists a number of Fields. The constraint will generate a check to make sure it is not possible to create 2 instances. with the same values for these Fields.

It replaces the option uniqueKey and improves on it:

  • You can have more than one UniqueConstraint.
  • The check uses a dedicated query instead of a Finder, so that it will work even for null values.
  • No need to explicitly define a Finder.
  • No more loosely typed String to define the Fields.
ConvertUniqueKeyOptions Transmuter

You can automatically convert uniqueKey options by using the ConvertUniqueKeyOptions transmuter. In the µRadiant (version 1.8.3+), right-click on the Application and select Convert Unique Key Options.
