Query causes error

const user = await database.query.users.findFirst({
  where: eq(users.id, id),
  with: {
    links: true,
    reactions: true,
    friendships: true
  }
})

const user = await database.query.users.findFirst({
  where: eq(users.id, id),
  with: {
    links: true,
    reactions: true,
    friendships: true
  }
})

Is there something wrong? Thanks.

Looks good (if these relations exist). Any particular error?

TimoOP•5mo ago

well, the catch-part of a try-catch-block is entered and run. user is never set Error: There are multiple relations between "friendships" and "users". Please specify relation name here this is the error

//// Friendship Model
export const friendships = pgTable(
  'friendships',
  {
    userId: uuid('user_id').references(() => users.id),
    anotherUserId: uuid('another_user_id').references(() => users.id),
    createdAt: timestamp('created_at').notNull().defaultNow()
  },
  (table) => ({
    primaryKey: primaryKey({
      columns: [table.userId, table.anotherUserId]
    })
  })
)

//// Friendship Relations
export const friendshipsRelations = relations(friendships, ({ one }) => ({
  user: one(users, {
    fields: [friendships.userId],
    references: [users.id]
  }),
  anotherUser: one(users, {
    fields: [friendships.anotherUserId],
    references: [users.id]
  })
}))

//// Friendship Model
export const friendships = pgTable(
  'friendships',
  {
    userId: uuid('user_id').references(() => users.id),
    anotherUserId: uuid('another_user_id').references(() => users.id),
    createdAt: timestamp('created_at').notNull().defaultNow()
  },
  (table) => ({
    primaryKey: primaryKey({
      columns: [table.userId, table.anotherUserId]
    })
  })
)

export const friendshipsRelations = relations(friendships, ({ one }) => ({
  user: one(users, {

    references: [users.id]
  }),
  anotherUser: one(users, {
    fields: [friendships.anotherUserId],
    references: [users.id]
  })
}))

this is the data model you will be able to see what the problem is 😉 I don't know it ...

on both relations user and anotherUser, just add a relationName :p

TimoOP•5mo ago

could you please show me an example? relationName? I am not used to it

rphlmr ⚡•5mo ago

export const friendshipsRelations = relations(friendships, ({ one }) => ({
  user: one(users, {
    fields: [friendships.userId],
    references: [users.id],
    relationName: "user"
  }),
  anotherUser: one(users, {
    fields: [friendships.anotherUserId],
    references: [users.id],
    relationName: "anotherUser"
  })
}))

export const friendshipsRelations = relations(friendships, ({ one }) => ({
  user: one(users, {
    fields: [friendships.userId],
    references: [users.id],
    relationName: "user"
  }),
  anotherUser: one(users, {
    fields: [friendships.anotherUserId],
    references: [users.id],
    relationName: "anotherUser"
  })
}))

yes when you reference the same columns, you have to add a unique relationName (what you want here)

TimoOP•5mo ago

and then? should I reset the database? or what? because the error does not disappear

rphlmr ⚡•5mo ago

no but I am creating an example based on your snippets

TimoOP•5mo ago

rphlmr ⚡•5mo ago
