ruby-on-rails - ActiveModel::MessagesController#create の UnknownAttributeError

Question

こんにちは、私は自分のウェブサイトにチャットセクションを作成しようとしていますが、取得し続けていますActiveModel::UnknownAttributeError in MessagesController#create

unknown attribute 'user_id' for Message.

ここで何が間違っているのかわかりませんが、

私のルートは

resources :conversations do
  resources :messages
end

ここに私の会話モデルがあります

class Conversation < ApplicationRecord
  belongs_to :sender, foreign_key: :sender_id, class_name: 'User'
  belongs_to :recipient, foreign_key: :recipient_id, class_name: 'User'
  has_many :messages, dependent: :destroy
  validates_uniqueness_of :sender_id, scope: :recipient_id
  scope :between, -> (sender_id, recipient_id) do 
    where("(conversations.sender_id = ? AND   conversations.recipient_id =?) OR (conversations.sender_id = ? AND conversations.recipient_id =?)", sender_id, recipient_id, recipient_id, sender_id)
  end
end

Message モデルでは、app/models/message.rb:

class Message < ApplicationRecord
  belongs_to :conversation
  belongs_to :user
  validates_presence_of :body, :conversation_id, :user_id
end

Conversations コントローラーの app/controllers/conversations_controller.rb:

class ConversationsController < ApplicationController
  before_action :authenticate_user!
  
  def index
    @users = User.all
    @conversations = Conversation.all
  end
  def create  
    if Conversation.between(params[:sender_id], params[:recipient_id]).present? 
       @conversation = Conversation.between(params[:sender_id], params[:recipient_id]).first
    else
       @conversation = Conversation.create!(conversation_params)
    end
    redirect_to conversation_messages_path(@conversation)
  end
  private
  def conversation_params
    params.permit(:sender_id, :recipient_id)
  end
end

主な問題は、メッセージ ページにリンクする行の会話インデックス ページにあると思います@message = @conversation.messages.new(message_params) メッセージ コントローラーの app/controllers/messages_controller.rb:

class MessagesController < ApplicationController
  before_action do
    @conversation = Conversation.find(params[:conversation_id])
  end
  
  def index
    @messages = @conversation.messages
    @message = @conversation.messages.new
  end
  def new
    @message = @conversation.messages.new
  end
  def create
    @message = @conversation.messages.new(message_params)
    if @message.save
      redirect_to conversation_messages_path(@conversation)
    end
  end
  private
  def message_params
    params.require(:message).permit(:body, :user_id)
  end
end

app/views/conversations/index.html.erb 内

<h1>My Inbox</h1>
<h1>All Conversations:</h1>
<% @conversations.each do |conversation| %>
 <% if conversation.sender_id == current_user.id || conversation.recipient_id == current_user.id %>
  <% if conversation.sender_id == current_user.id %>
   <% recipient = User.find(conversation.recipient_id) %>
  <% else %>
   <% recipient = User.find(conversation.sender_id) %>
  <% end %>
  <h3><%= link_to recipient.email, conversation_messages_path(conversation)%></h3>
 <% end %>
<% end %>
<h1>All Users:</h1>
<% @users.each do |user| %>
 <% if user.id != current_user.id %><h3>
 <%= link_to user.email, conversations_path(sender_id: current_user.id, recipient_id: user.id), method: "post"%></h3>
 <% end %>
<% end %>

app/views/messages/index.html.erb には

<% @messages.each do |message| %>
 <% if message.body %>
  <% user = User.find(message.user_id) %>
  <%= user.email %><%= message.message_time %>
  <%= message.body %>
 <% end %>
<% end %>
<%= form_for [@conversation, @message] do |f| %>
 <%= f.text_area :body %>
 <%= f.text_field :user_id, value: current_user.id, type: "hidden" %>
 <%= f.submit "Send Reply" %>
<% end %>

誰かが私に何をすべきか教えてくれるとありがたいのですが、これはチャットシステムをセットアップする良い方法ですか?
