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

Question

Good day, I am trying to create a chat section on my website but I keep on getting ActiveModel::UnknownAttributeError in MessagesController#create
unknown attribute 'user_id' for Message.
I don't know what I am doing wrong here,
my route is
resources :conversations do
resources :messages
end
Here is my conversations model
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
And in the Message model, app/models/message.rb: I have
class Message < ApplicationRecord
belongs_to :conversation
belongs_to :user
validates_presence_of :body, :conversation_id, :user_id
end
In the Conversations controller, app/controllers/conversations_controller.rb: I have
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
I think the main issue is in my conversation index page on the line that links to a message page #message = #conversation.messages.new(message_params)
In the Message controller, app/controllers/messages_controller.rb: I have
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
In app/views/conversations/index.html.erb
<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 %>
In app/views/messages/index.html.erb I have
<% #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 %>
I would appreciate if anyone can guild me on what to do right and is this a good way to setup a chat system?
