Issue in parseHasMany relationship

[Xubair-Dev]

Hi Team,

I am getting below error
parseHasMany - Model type for relationship activities not found

Please go through below codes

ParentActivity.ts
import { JsonApiModel, JsonApiModelConfig, Attribute, HasMany } from "angular2-jsonapi";
import { ChildActivity } from "./childactivity.model";
@JsonApiModelConfig({
type: 'parent-activity'
})
export class ParentActivity extends JsonApiModel {
@Attribute()
id:string;
@Attribute()
name:string;
@hasmany()
activities: ChildActivity[];
}

ChildActivity.ts
import { JsonApiModel, JsonApiModelConfig, Attribute, BelongsTo } from "angular2-jsonapi";
@JsonApiModelConfig({
type: 'child-activity'
})
export class ChildActivity extends JsonApiModel {

@Attribute()
id:string;
@Attribute()
name:string;
@Attribute()
description: string;

}

@Injectable()
@JsonApiDatastoreConfig()
export class ActivityDataStore extends JsonApiDatastore {

constructor(http: HttpClient, @Inject('API_URL') public linkToAPI: string) {
super(http);
this.config = {
baseUrl: this.linkToAPI,
models: {
activities: ChildActivity,
activityGroup: ParentActivity
}
}
}
}

Now in analysis I found issue in below lines
json-api.model.js -> JsonApiModel.prototype.parseHasMany ->
var modelType = Reflect.getMetadata('JsonApiDatastoreConfig', this.internalDatastore.constructor).models[typeName];

here typeName is child-activity which coming as undefined because in models array it is activities and its looking for child-activity.
The key activities referring from JsonApiDatastore models array and typeName 'child-activity' getting value from ChildActivity class type metadata.

I hope you understand the Issue and root cause.

Please share if you have any work-around or how can I override this function if possible.

Thanks
