Running ember-cp-validations using typescript

[gabrieltrita]

Environment

• Ember Version: 3.20.2
• Ember CLI Version: 3.20.2
• Ember CP Validations Version: 4.0.0-beta.10
• Typescript: 4.5.4

Steps to Reproduce

Hello everyone! I'm using native class in my project and we're migrating to Typescript. We have models like this in the current project:

const Validations = buildValidations({
  name: [
    validator('presence', true),
  ]
});

export default class UserModel extends Model.extend(Validations) {
...
}

when changing to typescript the Model.extend(Validations) stops working. Does anyone have an alternative? I've seen decorators like hasValidations implemented in the past, but it's been removed. I wanted to know if we have any alternative for the typescript. Thanks!

We are setting up a validated model first as an extension of the base ember-data model class, and then extending that extension, like this:

const ValidatedBaseModel = BaseModel.extend(Validations) as typeof Model;

export default class SeedModel extends ValidatedBaseModel {
