Data Constraints and Validators
May 24, 2017 by markpiller

It is very easy to configure rules for individual properties of the objects stored in Backendless. Available constraints include:

  • Not-null – forces saved/updated objects to have a value for the constrained property.
  • Unique – property value in the created/updated object must be unique across all other objects in the same table.
  • Indexed – indexes the stored values in the column to optimize it for faster searches.

The video below demonstrates the not-null constraint in action:
