Uninitialized Constant MessagesController

Question

I m building a simple chat app based on this rails cast  I m following along fine  but when I go to localhost  I get an error  uninitialized constant MessagesController  Message   This is generally a simple fix  but I have spent over an hour looking for the fix and I cannot see it  Here is my code   messages controller  class MessagesController  lt  ApplicationController      def index          messages   Message all     end      def create          message   Message create  params  message           PrivatePub publish to   messages new    alert     message content           end  end   model  message rb   class Message end   index  amp  message form  index html erb     lt h1 gt Hack Chat lt  h1 gt    lt ul id  chat  gt       lt    render  messages   gt   lt  ul gt    lt    form for Message new  remote  true do  f    gt       lt    f text field  content   gt       lt    f submit  Send    gt   lt   end   gt    lt    subscribe to   messages new    gt    routes rb   Hackchat  Application routes draw do     root to   messages index      resources  messages end   gemfile   source  https   rubygems org   gem  rails    4 0 0  gem  sqlite3   group  assets do      gem  sass-rails      gt  4 0 0      gem  uglifier     gt   1 3 0      gem  coffee-rails      gt  4 0 0  end  gem  jquery-rails  gem  private pub  gem  thin      gt  1 6 1    I have checked every possible thing I could think of as to why I would be getting this error  and I really do not know why  Any help would be much appreciated    Also  for using private pub  do I have to run two terminal windows  one running rails server  and the other running faye

Your model is  Messages  change it to  message   To change it like you should use migration   def change   rename table  old table name   new table name end   Of   course do not create that file by hand but use rails generator   rails g migration ChangeMessagesToMessage   That will generate new file with proper timestamp in name in  db dir  Then run   rake db migrate   And your app should be fine since then
