The problem with sending messages in the chat

when you enter a message in the form and click the "send" button, the message is not created, and, accordingly, is not displayed in the window. that a message is not created, checked by logs and consoles - in the logs there is a query in the SELECT database "messages". * FROM "messages" ORDER_BY created_at ASC, when prompted in the console Message.find (: id), for example 1, or 2, or 3 - gives an error, because the message was not created.

Message model belongs to User model

controllers/messages_controller.rb :

 class MessagesController < ApplicationController def new @message = Message.new @messages = Message.all.order('created_at ASC') end def create if current_user @message = current_user.messages.build(message_params) if @message.save flash[:success] = 'created successfully' else flash[:error] = 'oops, an error!' end end redirect_to root_path end private def message_params params.require(:message).permit(:body) end end 

index.html.erb :

 <div class="panel panel-default"> <div class="panel-body"> <ul class="media-list"> <%= render @messages %> </ul> </div> </div> 

_message.html.erb

 <li class="media-message"> <%= link_to image_tag(message.user.avatar_url, alt: message.user.name, class: "media-object"), message.user.profile_url, target: '_blank', class: 'pull-left' %> <div class="media-body"> <h4 class="media-heading"> <%= link_to message.user.name, message.user.profile_url, target: '_blank' %> says <small class="text-muted">[at <%= message.created_at.strftime('%-d %B %Y, %H:%M:%S') %>]</small> </h4> <p><%= message.body %></p> </div> </li>
