Rails - Aug 2013 - Getting started with rails guide: Encountering problems at Section 5.1

Hi people,

I need some help here. I''m new to ROR, and is following the guideline
on
"Getting started with rails". The inputs have been accurate and are
running
well until section:
"5.1 Laying down the ground word"*. *While navigating to 
http://localhost:3000/posts/new  the error message display were:



ActiveRecord::PendingMigrationError
Migrations are pending; run ''rake db:migrate
RAILS_ENV=development'' to
resolve this issue.
 





instead of what was suggested in the guide which is suppose to be:



[image: Another routing error, uninitialized constant PostsController]



How should I go resolve this issue? 

*I''m currently using ruby 2.0.0 and Rails 4.0.0*

Why don''t you do what the error says?

run "rake db:migrate RAILS_ENV=development"

Though you won''t normally need RAILS_ENV=development as it should
default to that.  First have a look in db/migrate and see if you have
accidentally created a new migration.

At this stage of the game, it''s hard to hear "yer doin it
rong" but something did go wrong. You should not have received that message
if you were following the getting started tutorial from the beginning. If you
were doing other things, you may have created a migration which the system is
complaining about. My suggestion at this point is to start the Getting Started
tutorial from scratch with a brand new rails app in a brand new directory.

WAT? Why would you start over when you could just rake db:migrate?
It''s quite easy to miss that when it tells you to run it, and missing
it is a far better in how to correctly build migrations than being
told to do it, because now you''ve learned the hard way to always
migrate.  I find it ignorant that anybody would tell somebody to start
over again rather than tell them how they broke it and to fix it and
the simple solution is: "You forgot to run a migration like they told
you to, lesson: run `rake db:migrate` after every migration.

Up to that point in the tutorial, there should not have been any migrations
created.

Its all a bit irrelevant anyway since the OP has shown no further
interest.  Perhaps he worked out what he was doing wrong and is too
embarrassed to reply.
