Problem Description

I created a Filter to generate random numbers within the chat.
It works normally, but before each request, I need to go through all the chat records to replace this random value.
It cannot be stored in the database, and I haven't found a better solution
Perhaps "Pipe" can achieve this function, but if we insist on using its proxy for every model, I believe it would be counterproductive.
It could also be that I am not very familiar with the project, and I am unable to find a reasonable solution

async def inlet(self, body: dict, __event_emitter__) -> dict:
        # This is where you manipulate user inputs.

        chat_id = body["metadata"]["chat_id"]

        random.seed(chat_id)

        __RANDOM__ = r"\{\{RANDOM\#\[([^\]]+)\]\#(\d+)\}\}"

        def replace_random(match):
            items = [item.strip() for item in match.group(1).split(",")]
            count = int(match.group(2))
            selected = random.sample(items, min(count, len(items)))
            return ", ".join(selected)

        for i, msg in enumerate(body["messages"]):
            if i >= 10:
                break
            if "content" in msg and isinstance(msg["content"],str):
                msg["content"] = re.sub(__RANDOM__, replace_random, msg["content"])

        return body

Desired Solution you'd like

There are optional parameters or other methods to directly modify the original content
