FAQPage Schema

How do I add a new property to an existing data model?▼

Add a new property to your data model by editing the source model file in /model/*.model/src/, selecting a valid property type (ValueProperty<T>, CommandedProperty<T>, RangedProperty<T>, EnumType, or string[]), then running model generation to propagate changes to client and server automatically.

What property types are supported when extending a model?▼

Supported property types include ValueProperty<T>, CommandedProperty<T>, RangedCommandedProperty<T>, RangedProperty<T>, EnumType, and string[]. Use unitful property names and ensure type selection matches your data structure requirements.

How do I propagate model changes to client and server code?▼

After editing source models in /model/*.model/src/, run model generation to automatically propagate property changes to both client and server models. Update corresponding Entity ViewModels and label converters afterward.

Can I edit generated model files directly?▼

No, do not edit generated files. Only modify source models under /model/*.model/src/, then run model generation. This enforces consistency and prevents manual changes from being overwritten.

What steps follow after adding a model property?▼

After running model generation, update the corresponding Entity ViewModel and server/client code to handle the new property. This ensures the property integrates fully across your MVC stack.
