How can I get a user’s name with their ID?
I’m creating a comments system in an app - only signed in users can comment. I want to store each user’s ID with the comment (each comment is a document), then get the user’s name to display on the page.
TL;DR
The user wants to get a user's name with their ID in a comments system. The solution provided is to either use the Users SDK inside a cloud function or create two collections, one for comments and one for user details. Storing the user ID with the comment and updating the second collection when the user changes their name can be a solution. This allows accessing the user's name without using a cloud function. 
Either
- Use the Users sdk inside a <:functions:1108648038156746792> cloud function
- Store the ID with the username - can be problematic in case the username has changed, for that you can go with this 👇 approach
2 Collections
1st collection will be
- comment
- date
- user_id
2nd collection will be the user details
- user_id
- user_name
So that's way you'll need to update only the 2nd collection when the user changes is name, and also you can make the second collection accessible without a having to use cloud function.
Seems a bit much - this is just an addon feature that’s not really required - it would just be a bit useful. I guess I’ll just store the name directly
