@casl/prisma: "equals" does not supports comparison of arrays and objects

[krutilins]

Can we perform validation based on nested models? Right now when I'm trying to achieve something similar, I'm getting an error: "equals" does not supports comparison of arrays and objects

        can(Action.Read, 'ChatConversation', {
          members: {
            some: {
              userId: activeMembership.id,
            },
          },
        });

Here is my simplified model:

model ChatUser {
  id String @id @default(cuid())

  memberships      ChatConversationMembership[]
  ChatMessage      ChatMessage[]

  @@map("chat_user")
}

model ChatConversation {
  id   String @id @default(cuid())

  members     ChatConversationMembership[]
  ChatMessage ChatMessage[]

  @@map("chat_conversation")
}

model ChatConversationMembership {
  userId String   @map("user_id")
  user   ChatUser @relation(fields: [userId], references: [id], onDelete: Cascade, onUpdate: Cascade)

  conversationId String           @map("conversation_id")
  conversation   ChatConversation @relation(fields: [conversationId], references: [id], onDelete: Cascade, onUpdate: Cascade)

  @@unique([userId, conversationId])
  @@map("chat_conversation_membership")
}

model ChatMessage {
  id Int @id @default(autoincrement()) @map("id")

  conversationId String           @map("conversation_id")
  conversation   ChatConversation @relation(fields: [conversationId], references: [id], onDelete: Cascade, onUpdate: Cascade)

  senderId String   @map("sender_id")
  sender   ChatUser @relation(fields: [senderId], references: [id], onDelete: Cascade, onUpdate: Cascade)

  content     String

  @@unique([id, conversationId])
  @@map("chat_message")
}

yes. You can do it like this: #528

can(Action.Read, 'ChatConversation', {
    members: {
            is: {
              some: {
                userId: activeMembership.id,
              },
            }
          },
        });

and you can check the access with (no is needed):

ability.can(
      Action.Read,
        subject('ChatConversation', {
          members: {
            some: {
              userId: activeMembership.id,
            },
          },
      )
