Sweep (fast): Sweep: Add message-id to messages list in API response #83

[Czechh]

Details

Current Implementation:

Actual call to http://MOTOR_URL/sessions/{session-id}/memory returns a list of messages in the following format:

{
    "messages": [
        {
            "role": "AI",
            "content": "Test."
        },
        {
            "role": "Human",
            "content": "Test"
        },
          ],
    "context": null,
    "tokens": 0
}

Enhancement Request:

In the messages list, it would be beneficial to include a unique message-id for each message. This enhancement would facilitate the ability to delete or update a specific message content. Here's the updated format:

{
    "messages": [
        {
            "role": "AI",
            "content": "Test.",
            "message-id" : "uuid"
        },
        {
            "role": "Human",
            "content": "Test",
            "message-id" : "uuid"
        },
          ],
    "context": null,
    "tokens": 0
}

Step 2: ⌨️ Coding

• src/memory.rs ✅ Commit 62a7012

• In the `MemoryMessage` struct in `src/models.rs`, add a new field `message_id: String`.
• In the `get_memory` function, update the creation of `MemoryMessage` objects to include the `message_id`. The `message_id` can be generated using a UUID library like `uuid::Uuid::new_v4().to_string()`.
• In the `post_memory` function, update the creation of `MemoryMessage` objects to include the `message_id`. The `message_id` can be generated using a UUID library like `uuid::Uuid::new_v4().to_string()`.
• In the `delete_memory` function, update the deletion of memory messages to delete messages based on the `message_id`.
