How scope a database to a logged in user using Hilt? The problem is that a database should also be kind of singleton scoped but also scoped to a new user when logging out and in.

Scopes used to confuse me a lot and I think Jake explained it well once, but basically... Only you know the lifetime of a scope such as "UserLoggedIn" and so if you just create a new scope, then instantiate it when the user is logged, then get rid of it on log out, and that should be what you need. Just a heads up that I've never created a custom scope actually, but I read into it a lot when I tried doing the same thing that you're doing. I wanted a UserLoggedIn scope and UserLoggedOut scope but a few different questions online ended up talking me out if it. I think Uber had done this in their RIBS architecture.

Yeah I'm experiencing the same. I can't even find proper samples and this is a common problem in a real world application

Hey I recently implemented an AuthenticatedScope with dagger. If you’re using Hilt a great starting point is https://medium.com/androiddevelopers/hilt-adding-components-to-the-hierarchy-96f207d6d92d

Yes I am referring to this right now, but i just learned that WorkManager cant access dependencies of custom components

@exfalso What is it in particular you aren’t sure about? It’s basically the same as the article but I added some extension functions to make injecting less verbose

yea i was just wondering because if i build a AuthComponent with my DB, then every other dependency would have to get manually injected using EntryPoints and this would be super messy

Yeah most of our repositories are auth scoped as well. I made them extension properties on the component, so injecting looks like:

private val userRepository = authManager.component.userRepository

mhmm

Can you not constructor inject your auth manager into work manager?

WorkManager would need to be SingletonScoped so the scopes would clash

What scope does it have

I think WorkManager has to be Singleton, and my repositories would be scoped to AuthComponent which is technically one layer below Singleton so the dependency is not available to the WorkManager

amazing, I had exact this problem last week but decided to implement explicit database closing when logging out. This is much nicer, will adopt 🙏
