Should repositories know about authenticated user?

[mr746866]

In my project, I need to fetch some data related to the authenticated user, and for that I need the userId of the user. I have an AuthManager class that gives me the userId of the authenticated user. I am confused whether to add this AuthManager class as a member of my UserRepository implementation, or just get the userId from AuthManager outside the repository and provide it when needed. Basically I have 2 options.

Option 1: Add AuthManager as a member to the UserRepository implementation. UserRepository will contain functions like getAuthenticatedUserFirstName(), getAuthenticatedUserLastName() etc. In the implementations of these functions use the AuthManager to get the necessary userId internally.

Option 2: Leave out AuthManager from the repository. UserRepository will contain functions like getFirstName(String userId), getLastName(String userId) etc. When calling these functions, use the AuthManager to get the required userId parameter.

Looking for feedback and suggestions.

@android10 Can you please shed some light on this?

Option 2 would be better. Not only it makes your functions generic (and reusable, when using different id as parameters), it also separates the concern. AuthManager is a "Manager" and not a repository. You may create something like SessionRepository to store session related data. and you can use that repository in the use case

@mr746866 Your other option is to create a custom scope... I call this my session scope, and in that scope I have my user model as a provided model, so I can inject it anywhere in my data layer which gives me acess to my userID and such, and as long as your data layer objects are scoped in the session graph they'll be able to inject the user modle... or you could even do @Named("userId") @Provides String userId or something to that effect.
