V5 - Relationship getter with parameters

[danpospisil]

Hi,

I have an app in v4.1 - I am using simple User model with OneToMany relationship to get user configuration (stored in Config model). I have a method defined directly in App/Models/User.js which gets specific configuration option - specified by moduleName and optionName. The method also decrypts the value it if necessary (I need to encrypt sensitive configuration options only - not all of them):

async getConfigOption(moduleName, optionName) {
		let option = await this.config().where('module', '=', moduleName).where('option', '=', optionName).first()
		//some more logic - decrypting option if necessary
	}

Now I am trying to convert it to v5 and I have this working code:

async getConfigOption(moduleName, optionName) {
		let option = await this.related('config').query().where('module', '=', moduleName).where('option', '=', optionName).first()
		//some more logic - decrypting option if necessary
	}

As I said, the code seems to work, but I am getting these error messages:

app/Models/User.ts:45:37 - error TS2345: Argument of type '"config"' is not assignable to parameter of type 'ExtractModelRelations<this>'.

45     let option = await this.related('config').query().where('module', '=', moduleName).where('option', '=', optionName).first()
                                       ~~~~~~~~

  Each member of the union type '(<Result extends unknown = LucidRow>() => RelationQueryBuilderContract<LucidModel, Result>) | (<Result extends unknown = LucidRow>() => HasManyQueryBuilderContract<LucidModel, Result>) | (<Result extends unknown = LucidRow>() => RelationQueryBuilderContract<...>) | (<Result extends unknown = LucidRow>() => ManyToMan...' has signatures, but none of those signatures are compatible with 
each other.

45     let option = await this.related('config').query().where('module', '=', moduleName).where('option', '=', optionName).first()
                                                 ~~~~~

What am I missing? I bet its something basic..

I have managed to fix this by using this workaround:

let user = await User.find(this.id)
let option = await user!.related('config').query().where('module', '=', moduleName).where('option', '=', optionName).first()

I don't find this as a very clean approach. Is there any other solution?
