First of all, thanks :)
With regards to ViewModels, there are several available strategies that you can employ.
- To control the hiding and exposing of properties, you can use the inclideInApi option of a field, for example:
class User{
...
@Fields.string({ includeInApi:false })
password='';
}
Or an authorization rule:
class User{
...
@Fields.string({ includeInApi:"Admin" })
password='';
}
Or even a condition that is based on the instance itself:
class User{
...
@Fields.string<User>({ includeInApi:(remult)=>/* some rule */ })
password='';
}
-
You can use the serverExpression field option, to enrich the view model with server data. Here's an example from the CRM-Demo
-
You can also use the sqlExpression if you're using Postgres to create more sophisticated sql's
-
You can use multiple entities that view the same database table and optionally use inheritance to reduce duplicity, for example:
@Entity("deliveries")
export class Deliveries {
@Fields.uuid()
id?: string;
@Fields.string()
name = '';
@Fields.boolean()
deleted = false;
}
@Entity<ActiveDeliveries>("activeDeliveries", {
dbName: 'deliveries',
backendPrefilter: {
deleted: false
}
})
export class ActiveDeliveries extends Deliveries {
}
- For the more complex scenarios, you can use the Backend Methods
If you have a specific example that you are interested in, please share it here, and we'll be happy to review it together.

Thanks for the reply. I have been mentoring a group for a while and we have been reviewing some nodejs frameworks these questions came to mind while in that brief review.
