ruby-on-rails - Ruby on Rails 中的 ruby​​-openai api gem : how to implement a streaming conversation?

Question

Openai 提供了一个 API，允许您实现 ChaGPT 或 DAL-E 等 AI 服务。对于 Ruby on Rails 应用程序，有几个可用的 gem，其中有 ruby-openai。

它工作得很好，但唯一的问题是它没有流对话功能，这意味着您一次只能发送一个问题请求，而没有任何对话历史记录。换句话说，API 会忘记您在发送回复后提出的每个问题。

那么我们该如何解决这个问题呢？

Answer 1

基本上，您需要自己实现整个行为。以下是所有实现步骤，包括 dal-e ai 的实现，其响应包含多张图片而不是一张。

您还可以找到我的整个存储库 HERE 并克隆应用程序!!!

实现流对话功能

基本实现

查看Doug伯克利的Notion Page API的基本实现

实现流式对话

默认情况下，openai gem 不具备该功能，因此必须自己实现

1. 使用 3 个表(对话、问题、答案)创建数据库，其结构如下:

# schema.rb
ActiveRecord::Schema[7.0].define(version: 2023_05_29_194913) do
  create_table "answers", force: :cascade do |t|
    t.text "content"
    t.integer "question_id", null: false
    t.datetime "created_at", null: false
    t.datetime "updated_at", null: false
    t.index ["question_id"], name: "index_answers_on_question_id"
  end

  create_table "conversations", force: :cascade do |t|
    t.text "initial_question"
    t.datetime "created_at", null: false
    t.datetime "updated_at", null: false
    t.text "historic"
  end

  create_table "questions", force: :cascade do |t|
    t.text "content"
    t.integer "conversation_id", null: false
    t.datetime "created_at", null: false
    t.datetime "updated_at", null: false
    t.index ["conversation_id"], name: "index_questions_on_conversation_id"
  end

  add_foreign_key "answers", "questions"
  add_foreign_key "questions", "conversations"
end

路线

Rails.application.routes.draw do
  root "pages#home" # supposes that you have a pages controller with a home action
  resources :conversations, only: [:create, :show]
  post "question", to: "conversations#ask_question"
end

主页 View (只有一个重定向到创建对话操作的按钮 - 见下文)

<h1>Let's talk</h1>
<%= button_to "Create New Conversation", conversations_path, method: :post, class: "btn btn-primary my-3" %>

Controller app/controllers/conversations_controller.rb

class ConversationsController < ApplicationController
  def create
    @convo = Conversation.create
    redirect_to conversation_path(@convo)
  end

  def show
    @convo = Conversation.find(params[:id])
  end

  def ask_question
    @question = Question.new(content: params[:entry])
    conversation = Conversation.find(params[:conversation])
    @question.conversation = conversation
    @question.save
    if conversation.historic.nil?
      response = OpenaiService.new(params[:entry]).call 
      conversation.historic = "#{@question.content}\n#{response}"
    else
      response = OpenaiService.new("#{conversation.historic}\n#{params[:entry]}").call
      conversation.historic += "\n#{@question.content}\n#{response}"
    end
    conversation.save
    @answer = Answer.create(content: response, question: @question)
    redirect_to conversation_path(conversation)
  end
end

显示页面app/views/conversations/show.html.erb

<h1>This is your conversation</h1>
<p>Ask your question</p>
<form action="<%= question_path %>", method="post">
  <input type="hidden" name="conversation" value="<%= @convo.id %>">
  <textarea rows="5" cols="33" name="entry"></textarea>
  <input type="submit" class="btn btn-primary">
</form>

<br>

<ul>
  <% @convo.questions.each do |question| %>
    <li>
      Q: <%= question.content.capitalize %> <%= "?" if question.content.strip.last != "?" %>
    </li>
    <li>
      A: <%= question.answers.first.content %>
    </li>
  <% end %>
</ul>

<%= link_to "Back", root_path %>
