Derive username from userId

How can i derive the username using a user id? I have these entities: entity JobAd {=psl id Int @id @default(autoincrement()) description String owner User @relation(name: "createdBy", fields: [ownerId], references: [id]) ownerId Int provider User? @relation(name: "servedBy", fields: [providerId], references: [id]) providerId Int?
psl=} entity User {=psl id Int @id @default(autoincrement()) isProvider Boolean @default(false) psl=} In my client side, i have a tsx file with the following signature: const SearchResult = ({ jobAd } : { jobAd: JobAd }) => { const { description, ownerId, providerId } = jobAd; How can i get the email address that was used for this user? something like: const username = getUsername(ownerId)

Hi @OrBlatt. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave: ---------------------- Based on the provided knowledge sources, Wasp provides a helper function getUsername that can be used to get the username of a user. However, this function requires a user object as an argument, not a userId. The getUsername function returns the user's username or null if the user doesn't have a username auth identity. Here is an example of how to use it:

import { getUsername } from 'wasp/auth'  
  
const MainPage = ({ user }) => {  
 const username = getUsername(user)  
 // ...  
}

import { getUsername } from 'wasp/auth'  
  
const MainPage = ({ user }) => {  
 const username = getUsername(user)  
 // ...  
}

In your case, you would need to first fetch the user object associated with the userId (either ownerId or providerId), and then pass this user object to the getUsername function. Unfortunately, the knowledge sources do not provide information on how to fetch a user object by userId in Wasp. You might need to create a query to fetch the user object from the database using the userId. Please note that there is an open issue on GitHub discussing the possibility of rethinking the getUsername and getEmail functions to make them methods or properties on the AuthUser object, which might change how these functions are used in the future.

Don't worry though, I've pinged my support and they will try to fix me up! :technologist: Perhaps try again in 15mins?

Wohooo @OrBlatt, you just became a Waspeteer level 2!

kapa.ai•3mo ago

Let me check the knowledge base for you. One moment! :books: ---------------------- To fetch a user object from the database using the userId, you can create a query in Wasp. Here's an example of how you might do it: In your main.wasp file, declare the query:

query getUserById {
  fn: import { getUserById } from "@src/user/queries.js",
  entities: [User],
}

query getUserById {
  fn: import { getUserById } from "@src/user/queries.js",
  entities: [User],
}

Then, in src/user/queries.js, implement the query:

export const getUserById = async (args, context) => {
  const User = context.entities.User
  return User.findOne({
    where: {
      id: args.id
    }
  })
}

export const getUserById = async (args, context) => {
  const User = context.entities.User
  return User.findOne({
    where: {
      id: args.id
    }
  })
}

In this example, getUserById is a Node.js function that takes two arguments: args and context. args is an object containing the data passed in when calling the query (in this case, the userId), and context is an additional context object passed into the query by Wasp. This object contains user session information, as well as information about entities. You can then use this query in your client-side code to fetch the user object:

import { useQuery } from 'wasp/client'
import { getUserById } from 'wasp/client/queries.js'

const { data: user, error } = useQuery(getUserById, { id: ownerId })

import { useQuery } from 'wasp/client'
import { getUserById } from 'wasp/client/queries.js'

const { data: user, error } = useQuery(getUserById, { id: ownerId })

Please note that this is a simplified example and you might need to adjust it according to your needs.

This is how the User and the auth entities are connected: https://wasp-lang.dev/docs/auth/entities#entities-explained You'll need to use the include option in Prisma to get the auth and the identities list. Alternatively, you'd save the username on the User using the userSignupFields. @kapa.ai tell us about both options

Auth Entities | Wasp

Wasp supports multiple different authentication methods and for each method, we need to store different information about the user. For example, if you are using the Username & password authentication method, we need to store the user's username and password. On the other hand, if you are using the Email authentication method, you will need to s...

Let me check the knowledge base for you. One moment! :books: ---------------------- Sure, let's discuss both options: 1. Using Prisma's include option to get auth and identities list: In Wasp, the User entity is connected to the rest of the auth system through the Auth and AuthIdentity entities. The Auth entity is connected to the User entity via a one-to-one relationship, and the AuthIdentity entity is connected to the Auth entity via a one-to-many relationship. When you want to fetch a User along with its associated Auth and AuthIdentity entities, you can use Prisma's include option. However, the knowledge sources do not provide a specific example of how to do this. 2. Saving the username on the User using the userSignupFields: The userSignupFields is a feature in Wasp that allows you to define extra fields that need to be set on the User during the sign-up process. For example, if you have a username field on your User entity, you can set it by defining the userSignupFields like this:

    import { defineUserSignupFields } from 'wasp/server/auth'  
  
    export const userSignupFields = defineUserSignupFields({  
     username: (data) => data.username,  
    })

    import { defineUserSignupFields } from 'wasp/server/auth'  
  
    export const userSignupFields = defineUserSignupFields({  
     username: (data) => data.username,  
    })

In this example, the username field of the User entity is set to the username property of the data object, which is the data passed to the sign-up process. You can read more about the userSignupFields function here (https://wasp-lang.dev/docs/auth/overview#1-defining-extra-fields).

I don't understand the options. @miho @kapa.ai Here's what i have: main.wasp query getUserById { fn: import { getUserById } from "@src/queries", entities: [User], } server side: queries.ts export const getUserById: GetUserById<{ userId: number }, User> = async (args, context) => { return context.entities.User.findMany({ where: { id: args.userId }, include: { auth: true, identities: true } }) } client side: import { getUserById, useQuery } from 'wasp/client/operations' const { data: ownerUsername, error } = useQuery(getUserById, { id: ownerId }) Why isn't it working?

kapa.ai•3mo ago

Let me check the knowledge base for you. One moment! :books: ---------------------- Based on the provided code, it seems like you're trying to fetch a single user by their ID, but you're using findMany which is used to fetch multiple records. You should use findUnique instead when you're fetching a single record by a unique identifier like id. Here's how you should modify your getUserById query:

export const getUserById: GetUserById<{ userId: number }, User> = async (args, context) => {
  return context.entities.User.findUnique({
    where: {
      id: args.userId
    },
    include: {
      auth: true,
      identities: true
    }
  })
}

export const getUserById: GetUserById<{ userId: number }, User> = async (args, context) => {
  return context.entities.User.findUnique({
    where: {
      id: args.userId
    },
    include: {
      auth: true,
      identities: true
    }
  })
}

On the client side, the useQuery hook returns an object with data and error properties. The data property will contain the user object returned by the getUserById query. If you're trying to get the username, you'll need to access it from the user object. Here's how you can do it:

import { getUserById, useQuery } from 'wasp/client/operations'
const { data: user, error } = useQuery(getUserById, { id: ownerId })
const ownerUsername = user?.username

import { getUserById, useQuery } from 'wasp/client/operations'
const { data: user, error } = useQuery(getUserById, { id: ownerId })
const ownerUsername = user?.username

Please note that this assumes that the username is a property of the User entity. If the username is stored in the AuthIdentity entity, you'll need to access it differently.

In github I see https://github.com/wasp-lang/wasp/blob/f0bbdd37d91aa2480ae3df06c4147d0eae432449/waspc/data/Generator/templates/sdk/wasp/auth/session.ts#L55 async function getAuthUserData(userId: {= userEntityUpper =}['id']): Promise<AuthUserData> { const user = await prisma.{= userEntityLower =} .findUnique({ where: { id: userId }, include: { {= authFieldOnUserEntityName =}: { include: { {= identitiesFieldOnAuthEntityName =}: true } } } }) Can I use this to get the username of a user given a userId? @kapa.ai

kapa.ai•3mo ago

Let me check the knowledge base for you. One moment! :books: ---------------------- Yes, the function getAuthUserData in the provided GitHub link is a good example of how to fetch a user along with their associated Auth and AuthIdentity entities using Prisma's include option. This function takes a userId as an argument and fetches the corresponding user from the database, including the auth and identities fields. Here's the function for reference:

async function getAuthUserData(userId: User['id']): Promise<AuthUserData> {
  const user = await prisma.user
    .findUnique({
      where: { id: userId },
      include: {
        auth: {
          include: {
            identities: true
          }
        }
      }
    })
  // ...
}

async function getAuthUserData(userId: User['id']): Promise<AuthUserData> {
  const user = await prisma.user
    .findUnique({
      where: { id: userId },
      include: {
        auth: {
          include: {
            identities: true
          }
        }
      }
    })
  // ...
}

In this function, User['id'] is the type of the userId argument, AuthUserData is the type of the data returned by the function, and prisma.user is used to interact with the User entity in the database. You can use this function to fetch a user and their associated Auth and AuthIdentity entities, and then extract the username from the returned data. Please note that the actual implementation of this function might be slightly different in your case, depending on how your entities are defined and how the username is stored.
