Task cards should display if solved or not

[Lekesoldat]

Need a way / query to know if the task is solved by the current user.
Mybe a new db model called SolvedTasks?

I.e:

model SolvedTasks {
    userId String @map("user_id")
    taskId String @map("task_id")
    user   User   @relation(fields: [userId], references: [id])
    task   Task   @relation(fields: [taskId], references: [id])

    @@id([userId, taskId])
}
